NOTE: This is in chronological order.

Original timeline

Childhood

“	That’s the justification. From within itself, humanity is afraid of the things that they cannot comprehend, and from that fear breeds riots and madness. By that aspect, ignorance actually suppresses all the other virtues.	„
	~ Isaac Westcott to Elliot, explaining the reason why mankind fears their existence.

Born as "Ike", Isaac grew up in a town of mages who could use sorcery along with his childhood friends, Elliot Baldwin Woodman, Karen Nora Mathers and her sister Ellen Mira Mathers somewhere on the world.

When acquainted with people, it was not long before Isaac Westcott noticed the difference between himself and others. Westcott was a brilliant boy. If he were to be classified as a child prodigy or genius, than there would have been no objections. In the hidden village that inherited the blood of Magicians, his skills and excellence exceeded his contemporaries. His control over mana was even better than the adults. Only the elders and teachers of the village, and Elliot who self-appointed himself as his rival, could compete with him. Moreover, it was not just that. Linguistics, arithmetic, sports, Westcott had made extraordinary achievements in every field. However, in the end a degree of this level only served to exasperate the question. At that point yet, Westcott did not distinguish himself from others on this issue. Whatever the position, as long as they were traveling in the same road, there would come a day where others will catch up and vice versa.

But Westcott also noticed that the place where he stood was a contorted position that did not intersect with everyone else. He first noticed it when the dog raised in Westcott’s home passed away. The dog lived in his home since before Westcott was born and was a friend that had always been together with him since then. Westcott cried for his dog. Although he was still very young, he was still familiar with the concept of biological death. But above all, in Westcott’s heart, there was inexplicable excitement compared to the sadness. The sad expression of his parents, the faces of sympathetic friends, the remains of the dog that had passed away, and his own sorrow gave him a feeling of pleasure and "happiness".

Looking back at everyone around him, Westcott came to the conclusion perhaps everyone would have criticized this joy as immoral or inhumane. The reason behind his joy was not clear but he felt that the death of his dog woke up something inside him. Westcott did not allow this emotion to rise to the surface. He had the intelligence enough to know that it was a different feeling from everyone else, being prudent enough to understand the disadvantages of it being widely known.

Since the beginning of his childhood, Westcott had been taught this lesson. Just as Magicians choose to hide from humans, he decided to hide this emotion in his heart. Despite not knowing if it was fortunate or unfortunate, Westcott was skillful at manipulating his own emotions as a child. So, when Westcott told his parents that he would like to adopt a new dog after the death of his old pet, his parents quickly agreed to him. Westcott’s parents didn’t even dream that their son’s goal was not to bury the sadness of losing his old pet nor was it an attempt to find a new friend, but rather for the idea that if he raised another dog, he would get to see it die once again.

And so Westcott spent those days without being suspected by anyone. With rigorous but gentle parents, respectable teachers, and fellow students who shared his enthusiasm, under all of these conditions, he grew up. But just as he was ten years old, another misfortunate event struck. His mother, whom always had a weak body, suffered from a lung disease and passed away. Although he lived in a village of magic beyond human sensibility, it was impossible to resurrect the dead. The villagers mourned for her passing as they offered their condolences. They held compassion to Westcott’s father, who had lost his partner at a young age. And when standing by the side of his father, who was trying to hold back his tears, they assumed Westcott was dealt a similar blow to his heart. The death of the mother who gave birth and raised him gave Westcott an unparalleled sense of loss. However, at the same time, what Westcott remembered most was the first time experiencing the supreme sense of intoxication over the loss of human life. If he wasn’t careful, tears would leak out from his eyes. Surely his father and the other villagers thought he was filled with sorrow and despair.

As Westcott watched his mother being buried, he felt a supreme sense of pleasure for the first time in his life.

Genocide

1 year later, Isaac Westcott, who was a 10-year-old child at the time, was looking for Ellen and Elliot and found them in a mountain where Elliot was teaching Ellen magic arts. Elliot revealed to Isaac that unlike her sister, Karen Nora Mathers, who was a talented magician, she can’t succeed in anything and that made Ellen cry as Isaac and Elliot felt sorry for her and the future genocidal tyrant stroked Ellen’s head. In return, Isaac said he was going to help Ellen in her magic training. Isaac then questioned Elliot if their teacher was going to get mad at him again for using magic so visible (as the existence of mages are a secret of mankind). When Elliot wondered why humans fear magic so much, Westcott said that it was only natural to humans fear their power as fear creates madness and madness breeds conflict.

Months later, a group of normal people (humans) who feared the power of mages burned down their village and the few who managed to escape from their houses were gunned down or carbonized alive by the invaders. As Elliot, Karen and Ellen cried over seeing their families and friends being killed from distance, there was a boy who looked down upon the burning village without too much dismay. Ike, even with the hot winds against his face, stared at the village that had fallen into ruin, gazing intensely as his fellow compatriots were being shot dead. Although Elliot could not understand what Ike was thinking at the time as his face was illuminated by the fire, Elliot felt something resembling an uneasy sensation coming from him on that day. While the others survivors were feeling fury, sorrow and despair Westcott was the only one who felt joy, a kind of joy he never experienced before.

At that moment, he understood that he was different from others. He knew that his sense of self was abnormal. It was because of this that Westcott concealed these urges, thereby protecting himself from being isolated from the rest of the community. Although he had the temperament for finding joy in despair, he did not actively seek it. Despite keeping a dog in hopes for death, he didn’t think of killing it with his own hands. Instead, he loves when tragic incidents happens to him and everyone around him, confirming his psychological masoquism. In Westcott's mind, losing something and the despair caused by it is the ultimate sense of happiness that people can feel.

As Westcott watched the destruction of his village he changed his view of the world as humans had shown their fangs to Magicians. While burning with feelings of vengeance and joy, Westcott saw the opportunity to make everyone embrace his pain as he had nothing holding him back. While seeing humans killing his race, Westcott found it to be beautiful as inflicting despair and sorrow into people's heart is more pleasent than waiting for them lose something or someone. With this in mind, Westcott used this chance to declare war to the human race while hiding his true twisted sadistic tendencies of watching mankind losing everything.

“	Let’s create a world, to expel humanity, a world where only magicians can exist. This began with them, so is there no reason why we shouldn’t do it?	„
	~ Westcott to his friends, increasing the hate on their hearts

In hindsight, this was the oldest memory of the foundations that would lead to the beginning of DEM Industries. After that, ten years had passed. Elliot and the others had been buried under the research of magic. Of course, the world wasn’t simple enough for children of about ten years of age to live alone. Westcott and his friends thought it was necessary to rely on foster care during the first few years. Westcott and his friends were sent to an orphanage and lived there for a while. However, it didn’t take long for Westcott, who was a brilliant young boy with many talents, to win the fancy of a wealthy British elderly couple from Westcott Family. It also didn’t take long for the old couple to pass away due to an "unfortunate accident". Indeed, as soon as Ike obtained enough assets through covert means, he invited Elliot and the others to his home. For as much as time would allow, they obtained a taste of the mystery: Theosophy. Occultism, Alchemy, and the Kabbalah. From the falsifications made public to “humans”, they carefully uncovered the genuine article.

First Spacequake

Date A Live-First Spacequake

Years later, in the central part of the Eurasia continent, the three figures stood amidst the open wilderness. Ike, Elliot, Ellen. The three magicians who had grown up to be beyond recognition from that time had come to gather here.

When Ike ordered Karen to start the operation, Karen’s voice could be heard from the observatory through the communication device. At the same time, the device designed to draw out the circle--the magical furnace began to start up while growling out a low howl. From the skies, from the earth, from the air. The energy that resides in every substance in the world turned into dazzling light, swirling and coiling around the surroundings. Gathering all of the mana present in the world to a single focal point, thus creating a new life. By incorporating that power, Elliot and the others, who up until now could only tinker with a tiny amount mana through spells and books, could become all power wizards found in fantasy worlds.

Isaac and his friends summons the First Spirit, Mio Takamiya.

As they were about to start, Westcott said that an universal space that should only exist in humanity’s imagination is being changed into reality. If his calculations are correct, the space of the Spirit being born is to the extent of covering the entire earth and claimed the scale is enough to be called another world--the neighboring world. Like a god wannabe, Westcott then declared this is their world and are going to overwrite their world with the neighboring world. During this time, Elliot noticed Ike’s face as he was describing their hope looked the same as the face that he had displayed on that day when he watched his village being destroyed by humans. However, the summoning ritual of the First Spirit also caused the first spacequake, which destroyed a large portion of Eurasia and killed 150 million people. However, Westcott, Woodman and Ellen protected themselves by using defensive barriers made using sorcery. Afterwards, seeing the destruction that he had caused, Westcott simply laughed manically as he witnessed the destruction. A few minutes later, Isaac and his friends finally put his eyes upon their new creation, the First Spirit.

The First Spacequake's aftermatch.

Later, his company captured the First Spirit and used her in nazi-like experiments to study her energy. For years, Westcott kept the First Spirit under an underground laboratory where she suffered brutal human experiments by the hands of DEM scientists. Because of DEM's human experiments, the First Spirit grew up as a mature woman with the mentallity of an infant. Due to Westcott's abuses, the Spirit could not speak correctly or even think rationally as a normal person and the only thing she had as experience in her life time were painful human experiments where parts of her soul were extracted and turned into military weapons, as well as scientific human tests which she was forced to suffer physical and psychological abuses, all in order to extract her Spirit Mana that lead to creation of technologies that helped DEM Industries to rise as one of the most powerful corporations of the world. In the following years, the DEM created the Realizer and was able to rebuild the nations they destroyed, making their way to glory, fame and power.

At some point, Westcott fell in love with Mio and desired to keep her forever. 

Destroying Takamiya Family

Shido and Mana with Mio.

“	──Oh my, how troubling. I wasn’t intending to lie.	„
	~ Westcott before shooting Shinji Takamiya.

Following the first spacequake, DEM Industries became a huge company since their Realizers, which Westcott seems to have invented, helped with the reconstruction of the world that he destroyed. However, the Spirit he, Woodman and Ellen created managed to escape from them and ended up causing smaller spacequakes around the world for six months killing more millions in the process before suddenly disappearing.

However, one day after causing a spacequake, she was approached by a boy named Shinji Takamiya, who gave the naked girl his jacket and decided to bring her home with him. Upon arriving in his room, however, Shinji's sister, Mana, entered and immediately demanded an explanation as to why her brother was with a half-naked girl. Shinji tried to explain the situation, but just then the First Spirit sneezed. Mana was about to leave for her room to get her some clothes, only for her to use her powers to make her own clothes by copying Mana's school uniform. While living with Shinji and Mana, the First Spirit quickly started to gain knowledge of the real world by reading books, following the radio and watching tv and cassettes. As a result, her vocabulary quickly rose from the level of a baby to being able to perfectly speak Japanese. Shinji decided to give her the name Mio Takamiya, after the day he met her; the 30th. Upon receiving this name, Mio was so overjoyed that she cried. One time, Shinji took Mio around town and told her about everything that caught her attention. They went to an arcade where Shinji won Mio a bear plushy in a crane game. This is where Shinji told her about the feeling of 'like', causing Mio to boldly state that she liked him.

At some point, however, DEM discovered Mio's location, now going by the name Mio Takamiya, forcing her to go on the run with Shinji when they were on a date to teach her more things of the world. While running, Woodman appeared before them and blocked their path. However, he allowed them to pass after asking Mio if she is happy being with Shinji and she told him that she is. Elliot then decided he will defect DEM and help them to escape as he was disgusted with Isaac's crimes and vowed his love for Mio, thus confessing his feelings. Just as Ellen was about to capture Mio, Elliot blocked her attack and fought Ellen while claiming he changed sides, this left Ellen enraged and called him 'traitor'.

As Ellen and Elliot were fighting, Mio and Shinji escaped but they were soon confronted by Westcott himself and dozens of other armed mercenaries, who revealed that he had abducted Mana but was willing to trade her for Mio. Shinji, knowing he was lying and planned to kill both siblings anyway, he tried to run with Mio, but he was shot in the chest by Westcott using a gun, killing him in the process in front of Mio, who fell in despair and sorrow. This, however, caused Mio's powers to manifest in an act of rage, allowing her to escape with Shinji as Westcott watched in surprise. After successfully getting away, she used her powers to heal Shinji's wounds. However, no matter what she did, he wouldn't regain consciousness. This caused Mio to cry, finally realizing how much Shinji meant to her.

After thinking for a long time, Mio finally managed to come up with a plan to save Shinji. She then kissed Shinji, causing him to turn into light and be absorbed into her. Her plan was to recreate Shinji by nurturing him in her womb before giving birth to him. Her plan was to entrust him with her power so that he could become her eternal lover. Since the body of a normal human is frail to accept all her power at once, Mio only gave Shinji the power to take in the Spirit's power. Then, she divided her power, planting them like seeds into young girls in order for Shinji to gradually take their powers one by one. However, humans were not compatible with the Qlipha Crystals she created, causing them to turn into monsters and go berserk. Therefore, Mio decided to reverse their properties, turning them into Sephira Crystals to make them more compatible. To do so, Mio continuously had the Qlipha Crystals bond with humans, turn them into monsters and finally kill them in order to slowly purify them. Around this time, Mio successfully gave birth to Shinji, and left him to be adopted by the Itsuka family.

After DEM kidnapped Mana Takamiya, Shinji's pre-teen sister, Westcott turned her into a Wizard by doing horrible experiments in her body. Westcott's action resulted in remaining her lifespan to about ten years. Not long after that, Isaac installed a Realizer in her brain to block her memories about her past, resulting in amnesia. Soon after, Westcott filled Mana's mind with lies saying that she was abandoned by her parents, and he was the person who gave her a home on DEM. Since then, Mana was trained by DEM to become the Adeptus 2, the second strongest Wizard in the world right after Ellen Mira Mathers. 

Westcott later started his own military campaign by selling weapons and technologies to all military and police forces of the world but keeping his best creations to DEM itself. When DEM discovered that Mio was creating more Spirits like her by turning humans in Spirits, or for better words, "monsters", using the Sephira Crystals to purify them, Westcott immediately put the entire world against the Spirits, whom were normal humans before, but were forced to become part of such race he created. With this, the entire world was against the Spirits and all military forces founded their own secret-battallions, people who can use sorcery made by man; Wizards, to fight them as Westcott and DEM declared that Spirits are a threat to humanity's existence. In the following years, dozens of Spirits were killed by the Anti Spirit squads around the world, becoming Quasi-Spirits or into monsters that went on a rampage, killing thousands.

Around this time, Westcott also had his own mercenary squad of Wizards who were brainwashed by his Realizers and forced them to join his cause like fanatical-brutals-psychotics soldiers and committed the worst war crimes in his name without questioning the nature of their mission. 

Nia Honjou

1 decade later, a human girl named Nia Honjou mysteriously became a Spirit. While at first causing spacequakes like the other Spirits, at some point Nia was able to reintegrate herself with society. However, curious about where she came from, she used her angel and found about her former life. Following this, Nia started to use Rasiel to find information on everyone she encountered. As a result, she discovered the dark side of humanity, causing her to believe she could never trust anyone. Because of this Nia fell in love with the 2D world of manga and video games, since the characters in there could never harbor negative feelings towards her. However, she still wanted to live in society so contact with others was unavoidable. As a result, Nia started to treat others as if they were just characters in a video game, communicating with them but having no real interest in them as people.

Westcott in DAL spin-off prequel.

Around 10 years ago, she was able to get a job as a manga artist under the pen name of "Souji Honjou". The Manga written by her, "Silver Bullet", ended up becoming a hit. However, 5 years after she became a manga artist, Isaac and his company discovered her existence and sent Ellen Mira Mathers to capture her. Ellen managed to defeat Nia and capture her alive by catching her by surprise through a sneak attack. The fans of her manga diacovered that she had disappeared and it was believed to be because of an argument between her with her editor. While in DEM's captivity, Westcott and Ellen put Nia through horrible physical, psychological and sexual torture, such as cutting her belly while alive, opening her skull, her hands and legs got cut by a millimeters after another to make her go into her Inverse Form. However, no matter what they did she did not Inverted, however, the brutal torture sections continued 24/7 for the next 5 years.

At that time, Isaac has invested his money from DEM in creation of weapons and military hardware for the entire planet in order to maintain a false hope for human race that humanity has salvation in exterminating the Spirits, the cosmic beings that threatened life on Earth.

Ashcroft Project

Westcott enters in Edgar's office after discovering his betrayal.

Later, Isaac had put all forces of his company in looking Spirits' radiation on the Earth. A girl named Artemisia Bell Ashcroft from Special Sorcery Service, saw the efforts that the DEM was doing to find the Spirits, and save mankind. Artemisia offered her own body to Isaac's company to create a new weapon for humanity to help to kill the Spirits and save Human race. Taking Artemisia in hands, Isaac put Edgar F. Caroll as leader of the new project that would bear fruit for Westcott's plans in the future; which the project called Ashcroft Project that would be carried out in extracting Artemisia's mental forces and turning her memories into a deadly weapon. However, Edgar used this opportunity to betray Westcott and remove someone malefico like him from DEM command and take the post of DEM Managing Director to himself. However, Edgar's plan was failed by the treason of Minerva Liddell.

When Isaac realized Edgar's treason he ordered Ellen to cut his head off and ruthless killed all other officers who served in Edgar research team. Soon after Artemisia was free from DEM, she was captured again (it's heavily implied that Cecil O'Brien, Ashley Sinclair, Leonora Sears, three of Artemisia's best friends who put their lives in risky to save her from DEM were killed by Westcott and DEM for interrupting their plans) and Isaac brainwashed Artemisia by rewrite her memories and turning her into a sociopath killer to serve him as a "reserve Wizard" in a near future. Since then, Westcott has hidden Artemisia from SSS after putting her in coma.

Yard

Months later, ​​Isaac Westcott received a call from the police of London asking for his help to stop a mass assault on a bank. The criminal organization Yard was attacking a bank with more than 100 people hostage. In response to the request, Westcott requested the presence of the Adeptus 1, 2 & 3 (Ellen Mira Mathers, Mana Takamiya and Jessica Bailey) who were currently in London before the spacequakes mysteriously begin in Tenguu City. However, only Jessica and Ellen were present at Westcott's office.

He explained the current situation of the crime, he mentioned that the assault was being led by Charllote Meyers along with two other former Wizards of SSS, that were Daisy and Izabell, the trio were punished and expelled from the SSS for abusing of magical power that were given to them. After they had been expelled from SSS, they became Wizards of the criminal organization, Yard. After Westcott explained the situation to Jessica and Ellen he asked where Mana was at that moment. Ellen mentioned that Mana was going to the bank before she left the building of D.E.M. Later, Westcott received the call from the bank and the corporation blamed him for letting Mana Takamiya destroy the bank during the process. In response to this, Isaac punished Mana by making her pay the damage she caused to the bank by using her own salary.

Starting the Conflict

Months later, Isaac and his company noticed a large number of apparitions of Spirits in Tenguu City, Japan. He decided to sent Mana Takamiya to kill the Spirit that had killed 10,000 people, Kurumi Tokisaki and was planning to capture some of these Spirits as well.

Days later, Mana was defeated by Kurumi and she was in coma for a while. When JGSDF contacted DEM to send support, Westcott sent one of his greatest failures, White Licorice to give assistance to AST against the Spirits appearing one after another. The White Licorice was a powerful CR-Unit made to heavy combat, however, it was one of DEM's greatest failures as it was a CR-Unit that took the lives of dozens of Wizards from DEM who dared to wear it, implying Westcott sent a failed machine to his "allies" even knowing that all people who will wear it will die by having their brains crushed by the magic energy.

In the next days, White Licorice was stolen by Origami Tobiichi who used it to attack Kotori Itsuka for thinking she was the Spirit who killed her parents when she was a kid. However, the assassination was foiled by Shido who begged her to stop. Before Origami could think about his decision, she lost all of her strength and lost her consciouness.

After reading Origami's report, Westcott showed interest in Origami and thought that she could be useful for him as she was a strong Wizard able to use White Licorice when using it would kill most of the Wizards who dared to pilot it. He then made his way to Japan to free her from her punishment; expulsion of the armed forces and sentenced to life in prison.

Arrival in Japan

Isaac Westcott and Ellen Mathers first appearance.

Westcott made his first appearance at JGSDF base, intervening their decision on Origami's punishment. He tells the officials that he heard that an AST member was able to successfully pilot the White Licorice. When he heard that General Kiritani was planning on forbidding Origami from ever using a Realizer again, he uses his connections with the Minister of Defense, Saeki, to change Origami's punishment to a two month house arrest.

After the meeting, he then gives Origami a card with DEM's contact information, telling her that they would assist her if she ever needs help fighting the Spirits. Despite the aid he gave, Origami remained cautious, feeling something like fear from the man that passed by her a moment ago.

After leaving, he tells Ellen that everyone in the meeting were idiots that did not see how grave that matter was, viewing them as all incompetent fools who were weird enough to put the blame on a genius that is 1 in 10,000. Then, he states that if General Kiritani changes his mind, he should probably invite Origami into his own company, as it is regretful to give up someone who could pilot the White Licorice. He adds that with a magic treatment performed on Origami, she could become a Wizard comparable to Mana or Artemisia.

Ellen informs Isaac about Tohka.

Ellen informs him that they received a report about a girl that looks identical to the Spirit Princess had transferred into Raizen High School right after the Princess disappeared. Intrigued, he asks what was JGDSF’s action towards this matter. After being told that they only used the low accuracy vehicle type DS-06 to classify her as a normal person, he tells Ellen that a peace-loving idiot is much scarier than anyone with dementia. Deciding to take the matter in his own hands, he asks Ellen if her body is rusty from the lack of fighting with Spirits. As Ellen reaffirms that she will never lose to any opponent, Westcott gives off an ominous smile and manipulates an event where the students of Raizen High School will go in a trip to Irubi Island to take them out of civilization and start their operation in capturing Tohka without having to worry to get rid of witness.

Irubi Island's Incident

Westcott after he manipulated Origami's feelings.

After the Arbatel got destroyed by Yamai in Irubi Island, Ellen confirmed that Princess, was the Spirit that had disappeared on Tenguu City 3 months ago before their arrival. After Ellen confirmed the location of Tohka, she asked to Westcott if there exists a human capable of possessing the powers of the Spirits. After she said that Westcott became interested in Shido Itsuka and requested more informations about what happened in Irubi Island. But much to Ellen's shock, Westcott was not worried with his men and spaceship. After that, Westcott ordered Ellen to return to base and considered the mission a success despite all losses.

Ellen contacting Westcott.

Although Westcott had one of his spacecraft destroyed by Ratatoskr, he completely ignored what happened to his soldiers; the Arbatel Pilots, and did not even requested a ransom to his soldiers who died in the crash of Arbatel. When Ellen considered in saving the crew of Arbatel, he simply answered to let them die or be captured by Ratatoskr. However, it was all part of his plan, with the purpose of leaving some of the survivors being captured by Ratatoskr to have a direct conversation with them. He then revealed he installed a Realizer inside of the brains of all his soldiers before dispatching them to the mission, and once they had outlived their usefulness he would explode the heads of all his men.

Westcott Gives Ellen a Day-off

In the side story of Encore 2 which is set after the Irubi Island events, Westcott is inside of DEM HQ in Japan speaking with Ellen about the recent battle with Ratatoskr but soon he changed the matter and said to Ellen, his secretery, to take a day out of work. When Ellen asked the reason of why someone like him would give her a day off, much to her surprise, Westcott answer they were going to have a meeting with other DEM executives but soon the meeting was cancelled and there was nothing to do. Ellen then decides to follow his orders and took a day out of DEM.

Westcott later is seem considering taking a day out of work in the beach but his business in DEM are more important.

However, Ellen's Greatest Day was ruined by three girls known as Ai, Mii and Mai, three students from Raizen High School who became her nightmare after ruining her mission in Irubi Island. On monday, Ellen arrives at Westcott's office and is asked how was her Sunday as she late to work and add there was no need for her to scary most of his workers and officers. She answers saying it was the "best day of her life" but mentions that she hates Monday and much as her secretary's work. Hearing that, Westcott takes a chance to let her more angry and plays a joke. Westcott then says it was "Ellen's Greatest Day" as she looked like a furious beast and mentions how he loved to see her "cute expressions".

Inversion

Westcott at the hotel.

After the battle on Irubi Island, he appeared on the top floor of one of the most luxurious hotels of Tenguu, where he was reading documents created by Ellen, that talked about everything that was known about the Shido Itsuka and the sealed Spirits during the events at Irubi Island. When Westcott was informed that Ratatoskr was involved in the conflict of Irubi Island, he immediately decided to give them a "hell of greeting". Later, he sent Adeptus 3, Jessica Bailey, and small squadron of Wizard consisting of 10 soldiers of D.E.M corporation, the DEM Industry Alpha Team of Japan Branch, to AST HQ in Tenguu City, where they would reinforce the Japanese organization due to continuous failures of AST in capture or kill an Spirit.

No longer after, Isaac sent Jessica and her Elite Squad to capture Tohka Yatogami at Tenou Event (an educational festival which brought together several schools and thousand of students) and to kill as many innocent as possible since DEM Industries' private army needs to be in secret of the public an to prevent the society from discovering the existence of the top-secret super soldiers, Wizards. In truth, the main reason behind of that was to send a "slap" on the face of Ratatoskr for interrupting his plans. However, Westcott's plan failed when Origami and Mana defeated Jessica's forces and left her disabled. Nevertheless, Isaac also sent Ellen if there was some interference of Ratatoskr as a backup plan.

Westcott greeting Tohka.

Ellen captures Tohka and takes her to the building of the D.E.M Industries' Japanese Branch. Later, when Westcott is informed about Shido's disappearance he ordered DEM to search for him as Ellen stated he would be there in a few days.

After Tohka was imprisioned in a salon for hours, Westcott entered the room while Ellen asked some questions to Tohka (played for comedy). Tohka felt a feeling discomfort and felt temperature had dropped several degrees just when she saw him. He performed himself to Tohka in a formal way, but he couldn't hide his sadistic personality for too long after he told her his plans in destroying the mechanics of the reality. He tried to think in ways of how to torture her mentally, physically and sexual in order to make her go in her "original form". But when Westcott said about killing a loved in front of her, she reacted immediatally. Westcott noticed her reactions and asked to Ellen about her "loved one" and realized that her loved one was Shido Itsuka, and the best mode to mentally torture Tohka and make her go in Inverse was to kill Shido in front of her. Hearing that, he decided to wait for him as he knew Shido was going to save her at some point.

Westcott's district and the DEM building where he is keeping Tohka.

After he found out that Shido had joined forces with Kurumi to save Tohka, Westcott triggered the spacequake alarm to all civilians to enter in government shelters in order to decrease witness. Then, Westcott sent thousand of his troops to kill Kurumi and bring Shido to him who was fighting outside of the building. Kurumi decided to play his game and summoned tens thousand of her clones to fight against the troops of Westcott as Shido made his way through DEM's defenses. And then a conflict between DEM and Spirits had started.

Despair Event Horizon

Some hours later, Westcott asks Ellen, who was fighting outside, to come return to the DEM building as everything happened according to the plan. When Shido and Miku arrive to the isolation room, they are greeted by Westcott (in the light novel, he is seated in a chair in the darkness while in the anime he leaves from the wall), who congratulates Miku and asks Shido who he is when he noticed his face. Westcott then starts laughing and saying that all this time, things were in the palm of that woman's hand (the reason behind his surprise was that Shido is the boy that he murdered years ago when he tried to run away with Mio). 

After provoking Shido in a joke, he releases Tohka while saying that he's not as strong as Ellen. When Shido asks Miku to brainwash Westcott to make him open the cage, he tells Shido that he'll be in danger if he stands there while exposing an evil sadistic grin. Shido is then impaled by Ellen. Then, Westcott tells Tohka that she may use anything to stop Ellen, and if her powers are not enough, she can reach even further.

Watching her loved one about to be killed, Tohka tried to break the glass with all her strength but that was not enough. The despair causes Tohka to Inverse as she lost her self in the darkness of her mind, and thus Westcott tells the world that the Kingdom has inverted, and that they should welcome the arrival of the Demon King.

When Tohka is fully Inverted, Westcott tells Ellen that this is the first time he's seen such a perfect Inversion, and that this is their dream. Then, he asks Ellen to defeat Dark Tohka by bringing her head to him and begin the path to their goal. During their fight, Tohka points her sword at Westcott, but Ellen protects him but was severely damaged. Then, he asks her about her opinion on Tohka. Ellen says that she's very powerful, and she won't be able to beat her with her current wound caused by Origami Tobiichi. Westcott says that they'll retreat, adding that this Inversion was a great achievement, and that he even saw an unexpected face; Shido Itsuka. As he and Ellen are leaving, he bids farewell to Shido by calling him accidentally "Takamiya" (his old name before he was murdered by the latter) in the process. However, he quickly corrects himself and says that he doesn't know anything about Shido "Itsuka" as he disappeared with Ellen, leaving all his Wizard and troops behind to meet their doom at the hands of an Inverse Tohka.

DEM Civil War

Westcott calmly watching the DEM directors signing their "suicide" sentence.

“	Unreasonably meddling with the JSDF, personal utilization of equipment and Wizards, instructing a raid plan causing harm to the public, in addition of turning every corners of the office district into a war zone...!? Even if the damage was lightly estimated, it costs more than 1 billion pounds...! We also have a big weakness grabbed by the Japanese government! How on Earth are you going to fix all of this!?	„
	~ Roger Murdoch complained to Westcott and accused his embezzling.

At the DEM headquarters in Great Britain, the board members are reviewing Westcott's actions in Japan, which caused the deaths of several Wizards and the partial destruction of the office district, among other things. One of the board members, Roger Murdoch, asks Westcott what was he thinking back then. However, Westcott replies that everything was worth it, since they successfully inversed Princess. Murdoch claims that Spirits won't save DEM's future, and asks for a vote to remove Westcott as DEM's Managing Director.

When the Chairman Russel asks if it was right to demand a petition to remove Westcott from his MD post, the latter says that this is alright, since the board members have that privilege, even if he is the original founder of the company. However, it can be said Murdoch was only planning to take over Westcott's post.

The DEM directors after having their arms cut off.

When the chairman Russell counted how many raised hands there were, he says that there were none. This is because Ellen cut off their arms, since she considered this an offense to Isaac. However, Westcott says that they simply used the authority given to them. He also adds that their arms will be back to normal if they treat them with Medical Realizers, and that he'll give the company to all of them, once he finishes his "fun and self-gratification", which will happen soon compared to his 30 years of long waiting and planning to fulfill his dearest-wish to rewrite the world and end humanity.

Elliot visiting James in the prison.

Some time later, Elliot Woodman and Karen paid a visit to James Paddington, who was bein' held as a prisoner by Ratatoskr. At first, Paddington didn't move, but then his body was used as a human-speaker by Westcott who was controlling his body with a Realizer. The D.E.M seem to did something to James' body or mind because he was not psychologically stable while being captured, merely acting like a zombie for most of the time. Westcott tried to bring Elliot Woodman back to his side as said Ellen would please if he did so. However, Elliot Woodman refused to return to his side, instead he said he would do everything to stop Isaac and the DEM Industries. Instead of calling Westcott "Ike", Elliot called Westcott's full name in a righteous rage. In Elliot's eye, Isaac is no longer a friend, but merely a fiend with no hope of salvation. After that, Isaac Westcott left the Realizer inside James' body while saying he will show no mercy next time they meet. In the process, Westcott killed James by exploding his internal organs and ending the life of his subordinate.

Westcott suggesting to make Origami Tobiichi to join the DEM.

After that, at the DEM HQ, Westcott tells Ellen that Murdoch was right, and the loss of Mana Takamiya and Jessica Bailey will be a huge problem for targeting Spirits. The fact that he lost two of his most powerful Wizards would be a problem for DEM in the future, mainly when the final battle between Ratatoskr and DEM is going to happen soon enough. Ellen, however, says it's difficulty to find human soldier from the world's army that could become a good Adeptus agent to replace Jessica and Mana besides from Artemisia Bell Ashcroft who was is coma at the time. However, Westcott suggests the young Wizard who inflicted a wound on Ellen's body during the battle of Tenguu City, Origami Tobiichi, who is an outstanding girl who had potential to become the new Adeptus 2, much to Ellen's dismay.

"Westcott Wants You For D.E.M Army!"

Ellen with Mikie.

Taking place a few months after the battle of Tenguu City, Westcott and his secretary, Ellen Mira Mathers, received a huge blow from Ratatoskr after the battle. Noticing that hundreds of his Wizards were killed by Dark Tohka during the battle (curiously, it was him who discarded them), Westcott and the DEM army began a miltiary campaign to recruit more Wizards around the globe to replace the ones he lost.

Days later, Westcott had his men opening selective training at the DEM facilities from the world. And by "coincidence", he put Ellen in the Japanese branch to supervise Origami Tobiichi. There, Ellen personally called the Japanese AST and a few recruits of DEM to test their abilities so they might replace the lost Adeptus killed in the previous battles.

Under Westcott's commands, he made dozens of Wizards fight in a simulator that could bring them to a near-state of death, resulting in many DEM and AST Wizards injured. However, it turns out that Mikie, the protagonist, survived and fought Ellen but was almost killed many times. It was only then that Ryouko Kusakabe noticed that DEM was actually trying to humiliate AST for having less-powerful weapons and mainly for being Japanese.

After many competitions, Ellen and Mikie had their final battle in the pool, where the latter cheated (installing a mini-engine in her swimming board) to win just so she could get have her revenge on Ellen. Later, Ellen lost the poll battle and fall in tears and humiliation while Westcott could be heard laughing at Ellen on the speakers.

Returning to Japan

Westcott arriving in Japan in his private car.

Months passed after the battle that Isaac Westcott causedin Tenguu City was over, and as a result, the activities of DEM Industries stopped on Japan for a few months due to destruction caused by DEM forces and the Spirits, however, this did not prevent him to back again to Tenguu City, Japan.

Isaac Westcott traveled of the British Heathrow airport to reach Japan's Narita airport. The trip took three hours while Isaac Westcott again returned to Japan in private jet. Isaac Westcott made a great aura of darkness and fear wherever he went, but that did not stop people to show respect to Isaac Westcott, the most authoritative and influential businessman of the world. When Isaac Westcott arrived at Japan's Narita airport, he directly went to Japan’s Tokyo metropolitan Tenguu city’s hotel. While Isaac Westcott was in luxury car going to Tenguu City, he told Ellen that they should create a residence in Japan since they were more concentrated in this area and to avoid unnecessary travel and his secretary praised him for leaving his throne in United Kingdom but Westcott answered that he will be embarassed if she praise him like that, acting like a tsundere girl for the most of time. Isaac Westcott vented with Ellen about what happened over the last days, especially when the DEM Board of Member voted to remove him from the post of Managing Director, and he even showed his nihilism.

Westcott holding Natsumi's report.

Isaac Westcott then is informed of the Spirits who were around Shido, and he realized that the Ratatoskr was associated with everything that was happening around Shido. After this, Isaac Westcott manipulated the happy moments of Shido and other Spirits, and said he would let Shido and the Spirits deepen their trusts even more their to finally kill Shido once for all and make all Spirits into their Inverse Forms. During the process of research, Isaac said there was someone manipulating everything that was happening so far and implied it was probably that woman, Phantom.

Ellen and her squad surround Natsumi.

Days later after his arrival in Japan, Westcott ordered Ellen and Wizards squad to capture Natsumi in order to make her go in Inverse Form by torturing her. Some time later, Natsumi is thinking about other pranks to pull on Shido, but Ellen and other Wizards find her. They engage into a fight. After Natsumi uses Haniel several times on the Wizards, they end up becoming children. Ellen decides that she can't waste any more time and attacks Natsumi with her laser blade, causing her to release her powers, and the Wizards go back to normal. When Ellen is about to cut off Natsumi's limbs, Shido and the Spirits arrive to save Natsumi. Despite this, Ellen still has the upper hand, so Shido and the girls teleport with Natsumi to Fraxinus.

Ellen "saves" Origami from Westcott's men.

After the fight, several agents of DEM try to ambush Origami, since her disciplinary punishment has been decided. At the same time, she receives a call from Ellen, who asks her to join DEM under the request of Westcott himself. Origami refuses at first, but Ellen claims that they won't hurt Shido in the mean time, and that she could have access to special Realizers and information on the Spirit that killed her parents. Origami accepts the offer, Ellen attacks the group of men, and she welcomes Origami into DEM Industries. After Natsumi escapes from Ratatoskr, Shido looks for her in his house, only to find Ellen there, sitting on a sofa. When he tries to call Kotori, Ellen takes his phone, saying that the whole house is under her Territory. She also wants to ask Shido where is Natsumi as she had orders coming from Isaac Westcott. He refuses, and Ellen tells him that the peaceful days he has with the Spirits is only because DEM allows it. In exchange for Natsumi, Ellen will let him and the other Spirits live. Shido still refuses, and Ellen takes out her sword. When she threatens to cut his ear off, Shido's phone rings, and he takes to chance to run away, since Ellen is distracted. However, she redeploys her Territory once again. This time, she receives a call from headquarters, and leaves before saying that Shido is a lucky person.

Westcott refusing to flee from Murdoch's satellites.

While she's out on the street, she explains the situation to a subordinate. An artificial satellite is falling on Tengu city, and it's aiming at Westcott. Apparently, the board directors are trying to seize power by killing Westcott. Ellen felt regret for not chopping off their heads instead of their arms. She gives the subordinate orders to evacuate and to retrieve any Sephira Crystal that may be left behind.

When Ellen finds out that there's an artificial satellite falling on Tengu city to assassinate Westcott, she goes to the hotel so that they can evacuate. However, he is far from worried. He even claims that he must praise Murdoch on his attempt, and that Woodman's organization won't let Shido and the Spirits die. However, he decides to take some counter measures, since Ellen insisted. He thinks it's a good chance to test the Mordred CR-Unit, so he dispatches Origami to do the job.

GOETIA

Westcott maliciously smilling as he orders Ellen to finally destroy Ratatoskr once and for all.

“	I want to congratulate him for his 'magnificent plan'. However, I also have other objectives to him.	„
	~ Westcott, about an arrested Murdoch.

Days after the attempted assassination of Westcott, Isaac realized that Murdoch was responsible for the assassination. However, instead of killing him, he simply ordered to arrest Murdoch and the rest of the DEM Council that helped in the conspiracy. After Ellen show her dissatisfaction to Westcott's personality in showing mercy, he mentions to Ellen that he would help Origami to kill the Spirits or make her catch one of them, and let Origami do whatever she wanted; resulting in Shido being kidnapped.

Ellen asks Westcott if it's alright to let Origami act on her own judgment. To this, he says that he doesn't mind, since he wants Mordred's battle data and, if Origami is successful, he will put his hands in one or two Sephira Crystals. However, he also says that the bribe needed for the JGSDF became larger than usual. When Ellen looks unsatisfied, Westcott tells her that he has a different target for her: she'll use the airship Goetia to stop any support from Ratatoskr.

A while later, when Kotori decides to use Fraxinus to rescue Tohka, Kaguya, Yuzuru and Miku from Natsumi, the ship is attacked by Goetia. Ellen communicates with Kotori, and after telling her that her age or looks don't affect her personal abilities, she voices two requests. First: everyone in Fraxinus has three minutes to evacuate the ship. Second: the escaped survivors will give Woodman a message from Ellen, saying that she's coming for him. Then, a huge battle ensues between both airships and, after Ratatoskr believed they had won, Goetia fires at Fraxinus, greatly damaging it and killing most of Ratatoskr's combatents and non-combatents officers.

Westcott ordering Ellen to go after Origami in his last appearance at the First Timeline.

After the fight and some other missions, Ellen returns to Westcott. While he congratulates her, she regrets the fact that Goetia got hit once, and claims that Ratatoskr has an outstanding crew. After this, they talk about Origami, who became a Spirit recently. While she was an amazing Wizard, they are still going to target her. Westcott then orders Ellen to go after Origami, completely ignoring the fact she was once his ally. Once Inverse Origami appears, Shido and the others try to get to her, but they are attacked by Ellen, who claims that they can't hurt an Inverse type and added that Isaac wanted her alive no matter what. However, Kaguya and Yuzuru manage to distract her, giving Shido enough time to reach Origami. 

Kurumi shows up and messes with him for a bit before telling Shido that there is no salvation for Origami now. Kurumi says she does what needs to be done and summons her angel. Shidou tries to get away but Kurumi stops him using her ability and shoots him again with another gun, teleporting him to the past 5 years ago.

Date A Live x Danmachi - Memoria Freese: Ais Catastrophe

Sometime after Origami was sealed, an entity was came to life as a pure spirit born from the mana of all Spirits sealed by Shido Itsuka in his world, the entity named herself as Amalgam of Spirits. During her time alive, she was born as an innocent Spirit but in the meantime she admired the corrupt director of DEM, Isaac Westcott, and all of his atrocities and ambition. By her own free will, she decided merge herself with Westcott's persona, copying him and consequently becoming HIM in the body of a Spirit.

After becoming Westcott, now reborn as Kaguya, discovered the existence of other multiverses using the power she stole from other Spirits and decided to set herself as the rule of all existence by destroying the entire multiverse and killing all Gods of the existence. To start her own plans, she begins merging two worlds at the same time together. These "mergings" lead to catastrophic damage across both of the merging worlds, while also creating phenomenon that summon monsters in both worlds. These alone lead to the deaths of thousands of innocents on various worlds. 

Kaguya's first appearance.

After merging the worlds, Kaguya managed to open a portal between the worlds and teleported the heroes of DAL universe to the Second World: Kurumi Tokisaki, Shido Itsuka, Origami Tobiichi, Kotori Itsuka and Tohka Yatogami. After sending the said heroes to a dungeon filled with monsters, she took the form of Kurumi Tokisaki and attacked a party of adventurers near the dungeon, killing half of its squad and using her clones and letting them devour most of party alive with the solo purpose of incriminating Kurumi and other Spirits to the people of that world.

After passing the impression that all Spirits are monsters, she manipulates the Loki Familia, the guild responsible for sending adventurers to that dungeon and forces the main heroine of Danmachi's world, Ais, to fight Tohka to death while her other party members subjugated Bell and Shido. While the said heroines were fighting, Kaguya invades Ais' mind and discover she was a troubled person with psychological problems and a dark past full of tragedies and abuse. She then began to explore her fears and past while merging her with a Sephira Crystal to turn the heroine into an Inverse Spirit, locking up the pure heroine inside of her mind to see and feel the suffering and cruelty she experienced in her entire life for decades. When the two heroes begins their mission to rescue Ais, Kaguya immediately summons an Inverse Ais on the middle of the city, allowing them to save her. When the heroes finally managed to free Ais from her inverse form, Kaguya takes all the pain and suffering she Ais lived and threw back at her, resulting in her second Inversion; causing destruction to entire planet, killing billions.

Bell freeing Ais from Westcott's control.

However, to make her plans come to life, she needed Ais alive and so she took the form of Kurumi and returned to the past, to where the heroes could have a new chance to save Ais without breaking her Sephira Crystal, something is going to need if she wants to become the new God (Demon Queen) of the multiverse. When the heroes finally managed to save Ais from herself without breaking the Sephira Crystal, Kaguya and her plans were exposed by Kurumi, who then, finally, showed her true colors.

Kaguya reveals her true identity, including her own will, that is Isaac Westcott. Little by little, she express her true plans and how much she hated them. She then stated her true goal was to destroy the multiverse, "squeeze" the lives of all octillion living beings living in it in front of the Gods before turning the Heavens in a paradise of flesh and blood. When Lilirica, one of the main heroines of Danmachi cried and asked why Kaguya was doing that, she simple replied saying she was just pretending to be her sister and regretted for not killing her and cutting her head off due to her innocent personality. Before they could fight, "Westcott" taunts the heroes and states he is going to fight them in the form of Kaguya, a form Shido and his friends, can't hurt for being a close friend.

Shido and Bell defeats "Westcott" together.

With the Sephira Crystal pure, Kaguya proceeds to absorb the Sephira Crystal of Ais in herself, ripping off her soul and becoming an Inverse Spirit. As a Spirit, she begins to cause spacequake around the planet, causing the death of millions just to test her new powers. When the heroes are battling Kaguya Westcott, she begins to torture Bell in front of his friends by breaking his bones and ripping his skin. She then proceeds to summon a storm of darkness that destroyed the town they were in, making thousands of victims.

As a final act to end that battle, Kaguya tries to cut the head off Shido but she ended defeated anyway. In her final moments, she laughs insanely as she embraces the Shinigami sending her soul to Hell. Following her defeat, Shido and the Spirits are sent back to their Earth, ending the false Kaguya's reign of terror but Shido states his battle with the true Westcott will continue before saying he will meet Bell and his friends from the other world again.

Date A Live x Toaru Majutsu no Index War

Days after Shido and his friends saved Origami Tobiichi from her Inverse alter-ego, a strange dimensional hole was opened between two worlds, sucking the Esper Level 5 Misaka Mikoto and her friends from Judgment, Esper 4 Level Shirai Kuroko, out of their world and teleporting them to Tenguu City, an alternative Earth of their world.

The airplane crash in Tenguu City.

Thanks to their unsual and different type of energy, Westcott and the DEM took interest in the girls and decided to capture them to conduct human experiments on their bodies, however, the girls are rescued by Ratatoskr and the sealed Spirits. Under the protection of Ratatoskr, the DEM forces spied the girls' daily lives as they learned more about the new world.

In order to lure them out, Westcott used his resources to hack a plane's system that was just leaving Tenguu City, with destiny to Tokyo. As a result, the plane fell over the town and crashed in the downtown, killing at least 800 people and burning the most of the downtown. With the speed of news, the world declared it as the Asia's worst plane accident of all time.

More coming soon with Chapter 2...

Second Timeline

Material A

“	Yes.----It’s about time we try making our perfect inverse type?	„
	~ Westcott to Ellen.

In the DEM Industry Japan branch, Westcott regrets the loss of the Spirit Devil, and claims that, other than Princess, he's never seen such a perfect Inverse type Spirit. While he wonders about what could have made her go inverse, he tells Ellen that the facility from Neryl Island, which is owned by DEM, has finally given results regarding Material A, with a success rate of 75%. Westcott claims that it's time they made their own perfect inverse type.

Shido flirting with Ellen.

Later, Westcott says that Ellen can take a rest for now after many days of hard missions. Soon afterwards, Ellen decides to go out to eat her favorite strawberry shortcake, but the cold weather annoys her. She remembers a subordinate who told her "Japan's winter is not a big deal". Then again, that subordinate was from Alaska. Suddenly, while thinking about adding strawberry shortcake to the company menu, she bumps into Shido. He tells her that he had feelings for her since their last meeting. And even though she is from DEM, she should go over to Ratatoskr. Ellen thinks this is a prank, and activates her Territory to crush Shido. However, he is unaffected by it. Then, she starts attacking Shido, but he dodges and blocks all of her attacks. After some more attacking, Shido lifts Ellen in a princess carry manner. Next, Shido decides to kiss Ellen, but ends up kissing her forehead since he doesn't want to force an unwilling girl. He goes away, and Ellen claims that she'll never forget this. With teary eyes, she returns to the company building, escaping from the public eye and from her chance to eat strawberry shortcake.

Meanwhile at Neryl Island, the DEM operatives are transporting the second Spirit, Nia Honjou, also know as Material A, out of Neryl Island, are attacked by Kurumi's clones, who was hunting down Nia Honjou to know informations about the First Spirit that Westcott, Elliot, Karen and Ellen summoned 30 years ago. The DEM Wizards are quickly overwhelmed, until Artemisia Bell Ashcroft (who was finally awake from her coma but had her memories altered to the point that she couldn't even recognize Origami Tobiichi who helped to save her life years ago) appears, wearing a CR-Unit like that of Ellen, and beheads several clones. After that, she uses her Territory to paralyze all the clones, and then kills the Kurumi that was leading them, thus securing the transport.

Some time after that, Westcott calls Ellen to his office. Back at the company building, she makes her way to Westcott's office, while thinking about what happened with Shido. Irritated, she hits the wall, but the pain makes her crouch down on the spot with teary eyes. Westcott then informs her that the Spirit Nightmare attacked the transporter that was carrying Material A. However, they solved the problem thanks to the new Adeptus 2. Changing the subject, Westcott informs Ellen about some strange Spirit readings. Ellen recognizes this "Spirit" as Shido Itsuka and claims she'll bring the target's head, however, Westcott reminds her that he prefer a living sample, as he bemuses over the cause of Ellen's overly ecstatic attitude. Westcott then wonders why Ellen is so angry and jokes at her cute behavior. Later, the Material A reacted to Shido's power when the DEM plane approached Tenguu City, causing the plane to fall along with the Material A, but apparently Westcott was aware it was coming.

After the fall of the plane Westcott called the two pilots, Knox and Burton, personally in his office. Because of their failure, it made the two pilots thought they were going to die at that moment, however, much to their surprise Westcott gave them a vacation and a reward for their failure. This confuses both pilots, to which Westcott adds that the treatments will be under insurance. However, Knox explains that they expected a punishment for letting Material A escape. Westcott then tells them that they are both great staff, who remained calm when Kurumi attacked, and he also planned to release Material A. Despite his kind words, Knox and Burton felt that they were being punished somehow by Westcott himself; being viewed as animals in a zoo.

Becoming Spirit & Dark Nia

Westcott becoming Inverse Spirit.

“	Thanks for you work, Artemesia. Looks like it was a right decision to have you hide yourself just in case. — Itsuka Shidou and everyone from Ratatoskr. Let me thank you too. Thanks to you, I'm able to get one step closer to my long-cherished wish. Let's meet again soon, Itsuka Shidou and all spirits. Do enjoy the rest of your peaceful days even though you only have a little left.	„
	~ Isaac Westcott becoming a Spirit.

Some days later, Ellen, Artemisia and Westcott are driving through Tengu city, and he once again says that Knox and Burton did an excellent job. Had they released Nia themselves, there would have been traces. Ellen does not agree with his decision of letting Nia go. Westcott reminds her that they were stuck for years trying to inverse Nia. But he also reveals that they didn't just let her go. They embedded a Realizer inside Nia's brain to make her forget what happened during the last 5 years. However, when Westcott gives the signal, that Realizer will activate, forcing Nia to remember everything and trigger her inversion. Then, he reminds Ellen of their dearest wish and tells Artemisia that he's counting on her as well.

Later, after Westcott noticed Nia found her peace and hope again, he activates the Realizer in her brain that was blocking her memories of her past during her time as guinea pig in DEM facility, forcing her to remember all torture he and his scientists did to her for the last 5 years; some of those tortures included opening her skull, removing her intestines, cutting her belly, cutting her limbs and brutal sexual tortures. As a result, Nia loses her sanity and screams in pain as she enter in Inverse Form. When Shido is trying to save Nia, Westcott appears, and greets Shido as Artemisia rushes to Nia and rips off her Qlipha Crystal. Then he congratulates Artemisia on her work, and puts Nia's Qlipha Crystal in his chest as he becomes a Spirit. 

Westcott succeeding in invert Nia.

After that, Isaac decided to try to use his new Spirit powers in invoking Beelzebub and creating an army of dark monsters. However, Isaac commanded they should go because his body would not endure several Inverted crystals and he was already happy to put his hands on the Demon King. His last words was "let's meet again soon, Itsuka Shidou and all Spirits. Do enjoy the rest of your peaceful days even though you only have a little left" before disappearing in the sky with Artemisia and Ellen.

In the building of his company, Isaac was happy like a child discovering a new toy while discovering the his new Spirit's powers. When checking out of curiosity, Isaac discovers that the world had already been rewritten once Shido Itsuka traveled to the past and changed the future to save Origami Tobiichi. He also discovered his powers were in incomplete form since Shido Itsuka had managed to make a part Nia's human mind back to her, but he did not bother with it and said it was a good result and was a step toward to his long-cherished wish. Westcott then looks at his book and let out a malicious smile as he prepares to go to another meeting.

Westcott's Cybernetic Attack!

Maruna Arusu, the humanoid virus of DEM.

Following the rescue of Nia after the incident in the Mangaka Event, Westcott and the scientist of DEM tried another attack to Ratatoskr, but this time, sending a virus to their system to take down their systems, destroy all electronic devices of Japan to throw the country into state of chaos and anarchy and destroy the city of Tenguu in a nuclear explosion using Fraxinus.

Creating an artificial intelligence based in AI Maria from Fraxinus, the DEM considered her as a failure and discarded her on Internet. Making her first appearance, the virus named Maruna Arusu (based on Marina Arusu from the non-canon game series) first shows up in the PlayStation 4 of Nia as it slowly goes into Fraxinus' system, hacking its defensive codes, shields, energy power, etc.

While pretending to be a "DLC" character, Maruna proposes a game to Nia where she has to take off her clothes in front of Shido. Following her gamer instincts, Nia accept the challenge while Maruna said her "father" (Isaac Westcott) will be proud of her if she wins. When questioned about her father, Maruna replies saying her father is her creator and the man who gave her life as an AI for free to all PS4 players (making a funny and indirect joke to EA in the real world).

Maruna commanding Nia to take off her clothes; funny programming made by Westcott.

As the game goes on, Maruna made Nia to take off all her clothes, leaving her only with bra and panties. At this point, Maruna had access to the Hospital Section of the ship, and following her programming, she disabled all medical machines, putting the lives of many patients in risk of death. Meanwhile, the game continued in Nia's room, but when Maruna ordered Nia to take off her panties, she immediately gave a 'rage quit', leaving Maruna angry and then revealing herself to Japan as a threat.

After discovering the place of origin of Maruna, Kotori came to the conclusion that Westcott and his DEM were trying to take down Fraxinus and take millions of lives with them. Soon afterwards, Maruna began to spread herself to all electronic devices of Japan and prepared to turn the entire country into a Hell on Earth. And following this, Maruna now was trying to control the military satellites of the world that belonged to Asgard Electronics, she then prepared to destroy all facilities of Asgard across the globe.

When Nia questioned why Maruna was doing this, she replied that she is doing it so she can be loved by her father, Isaac Westcott. But when questioned about her sense of morals, she immediately began to doubt Westcott's love for her as he abandoned her from the beginning. Using her sadness as an opportunity to stop this madness, Nia convinces Maruna to play a dating game with her so they can communicate with each other. In the dating game, Maruna said she always knew her father was not a person who could love and began to question her own existence. After a few minutes, Nia convinced Maruna to stop by saying she is going to love her... the game ends with the Nia (the protagonist of the game) and Maruna kissing and having 'sex' later.

Meanwhile in Fraxinus, the system of the ship returned to its normal and all electronic devices of Japan were now back to normal. Still confused by what happened, the crew of Fraxinus look at each other with pathetic faces. Meanwhile in DEM building, Westcott is disappointed that he failed to take Japan to the Stone Ages but was happy that their virus (his artificial daughter) almost had success. Even so, he admitted that he never once loved her and considered her as an "Discarded AI" from the beginning.

Maruna then became the virtual girlfriend of Nia from that day on.

Mukuro Planet

Mukuro destroying DEM forces.

A few days later, Westcott calls both Ellen and Artemisia to his office to inform them that Beelzebub has been receiving interference from an outside source, which he theorizes came from Sister's survival. Despite this heavily restricts the Demon King's omniscience function, he still managed to decipher the information he needed just in time. Thanks to this, he has found the location of a new Spirit. When Ellen questions where the Spirit is, he responds by raising his index finger and pointing to the sky.

Despite sending an entire armada against the new Spirit Zodiac, the fleet and troops are easily destroyed and Zodiac retaliates by transporting the debris simultaneously to DEM's international facilities. Seeing this display of power, Westcott notes that he never expected the vanguard troops to defeat her, implying he sent them to a suicide mission, but praises this power for its excellence. The tracking satellite remaining then notes that the Zodiac has remained at its previous coordinates. Reading Ellen's intentions, Westcott nods his head and decide to leave the capture to Ellen and Artemisia as it was troublesome to have his facilities around the world being destroyed. After Ellen leaves, a nearby Wizard questions if it is really okay to let Ellen go to outer space. Asking if his subordinate is questioning his orders, the Wizard quickly retracts her statement, saying that she is wondering if Ellen can still fight after finding out about that thing. As the Wizard muttered in a feeble voice, Westcott shrugged his shoulders and notes that this is how it should be. As he uncovers his right hand, a black levitating tome materialized with the instructions on how to capture to the new Spirit. He remarks that he expects a lot from Ellen, but for a long time, she wouldn’t want to avoid getting bathed in blood from head to toe. As he finished, Westcott lets out an indifferent laugh.

Much later, Westcott and his forces launch an all-out assault to the secret Ratatoskr facility with hundreds of drones and soldiers, having preciously discovered its location from Beelzebub. Per chance, he runs into Shido and his group just as they were racing towards the new Fraxinus. Seeing him present, Origami and Tohka immediately assume their limited Astral Dresses in an act of rage to kill him for everything he had done. Tohka's attack blows away the Wizard that is accompanying him, while Origami prepares to fire her laser from her Metatron. However, Westcott easily blocks the attack by summoning a book page to shield himself, with him noting that such a pathetic attack won't be able to harm him in his current state. As Westcott grins in a bewitching manner, he notes that this would be a perfect opportunity to test Beelzebub's abilities. As he activates Ashufiriya, enormous books start emerging underneath Shido and his group, eventually swallowing them in. As the Wizard asks where they had gone, he remarks that they are within a fairy tale, trapped in a fantasy. However, rather than focus on Shido, their current target takes precedence at the moment. He smiles and states that he is looking forward to meeting his old friend, Elliot, in person.

Fighting Ratatoskr

Westcott intercepted Woodman and Karen just as the two were about to enter their emergency escape helicopter. When questioned by his timely arrival by his old colleague, he admitted that he had to use his own intuition since the Demon King Beelzebub's information network was still scrambled by Sister. After exchanging pleasantries with his old friend, Westcott was asked if he had come to kill them. In response, he retorts that would defeat the entire purpose of not bringing Ellen along. If possible, he wishes to bring both Woodman and Karen back to DEM. Upon hearing Woodman's refusal, he responds by summoning Beelzebub and asks his old rival to at least entertain him.

The result of the battle is not shown. However, Westcott had lost one of his arms in the conflict and retreated with his forces. As Ellen raced back to DEM headquarters after her defeat by the new Fraxinus EX, she demanded to see Westcott over not being told about the raid on Ratatoskr's headquarters. However, much to Ellen's frustration, she finds that Westcott was in the middle of a Realizer treatment to recover from his wounds. Despite this, he happily waves his severed limb in front of both Ellen and Artemisia. He admits that he was magnificently defeated by them. Still, the front half of his severed arm was successfully recovered, so he should still make a full recovery by tomorrow. After hearing the medical staff's concern over continuing his treatment, Westcott tells them that he will have to postpone their chat until the next day and they should go heal their own wounds in the meantime.

Shido's Death and the Apocalypse

Westcott summons his daughters; Nibelcol.

“	Let that Sister throw a spanner in the works of my rootling around for all I care. With adequate welly, even the tiniest chink in Ratatoskr’s circumspection won’t be kept under their hats any longer. ——It’s about time we thoroughly proceeded with slaughter. Mercy is uncalled for. Flaunt the might of humanity’s strongest Wizard to your heart’s content.	„
	~ Isaac Westcott to Ellen Mathers and Artemisia Ashcroft.

Days after his battle with Ratatoskr, Westcott found himself in a state of inability inside of the DEM Industries Branch thinking in his next step after Mukuru managed to escape from his grasp thanks to the Sealed Spirits of Ratatoskr. Inside of the branch, Westcott calls Ellen and Artemisia to his office but when the latter enters in the room she notices a dark presence coming from the chamber and immediately thinks it was the Spirit Nightmare, Kurumi Tokisaki, who was attacking Westcott but it turned out it was nothing but himself. Westcott then explains to Ellen that her failures against Ratatoskr create a perfect scenery where he will be victorious and says the current circumstances shall precipitate the best-case scenario. Isaac then says it's time to end this and it is time for the massacre starts with a new kind of trick, when the proud Adeptus 1 questions him for doubting her strength, the director answers that Ratatoskr has now too many Spirits under their thumb and their numbers are too overwhelming even for Artemisia and Ellen and decides to bring "reinforcements" to assist them in this quest. Isaac Westcott then invokes several pages from his Demon King Beelzebub and summons several girls known as Nibecol, whom he named as "Daughters of the Demon King", leaving Ellen and Artemisia in shock.

Kurumi and Mana fighting Westcott's daughters.

Later, Ellen and Artemisia plans to ambush Shido Itsuka soon after he left Raizen High School with Kurumi Tokisaki but the Wizards were intercepted by Mana Takamiya, who prevented the assassination by attacking Ellen before she could attack. However, using Westcott's Demon King abilities, Ellen summons several Nibecol to attack Mana, who later mocked Ellen for being Westcott's lover and said their father (Isaac Westcott) had bad tastes. Ellen, following Westcott's orders, ignored Mana and retreated, Mana tried to follow her but was stopped by Nibecol who prevented her from following Ellen. Mana later received the help from Kurumi Tokisaki's clones and fought Nibecol until every single one of them were destroyed but it was later revealed they are immortal.

Later in DEM Branch, Nibecol blamed Ellen for being the first failing in the mission, that was enough for Ellen lose her cool and tried to kill Nibecol but she was stopped by Westcott who entered in the room as his daughters took cover behind him. When Westcott asked the reason of failure Nibecol claimed that there were many annoying people in the battlefield, such as Mana Takamiya and Kurumi Tokisaki's clones that stopped them from killing Shido Itsuka. Westcott then suspected that someone leaked the plans of his attack, or rather, the attack itself. Even so Isaac refused to accept defeat and planned another attack very soon.

This time, to ensure victory, Westcott sent Ellen, Artemisia and Nibecol in a surprise attack end Shido's life and the best moment for this was when Kurumi finally decided to confess her feelings in roof of the Shido's high school, thus creating a scenery where all Spirits, including Kurumi, will go into Inverse Form through seeing their loved one being murdered in cold-blood. Later, when Kurumi was chatting with Shido about sealing her powers, Nightmare (Kurumi Tokisaki's codename), was about to confess her feelings for Shido when suddenly Ellen impaled Shido's chest as they were distracted. The Spirits who were saved by Shido from AST and DEM so far, were watching the scene and rushed to save him but were stopped by Nibecol as they claimed it was time to make the dream of their "daddy" real.

Despite their efforts to pass through their defenses Nibecol displayed her masoquist and nihilistic personality by receiving all the attacks while laughing. In response to the attack, Kurumi summoned several of her clones as well and the roof became a rain of blood as Kurumi and Nibecol sliced and impaled themselves in a bloody batte. As Ellen watched the battle while stepping in Shido's back, Kurumi tried to save him but Artemisia cut off her arms before she could reach him. While everyone were distracted with Nibecol and Artemisia, Ellen claimed it was the end of Shido's life, in despair, Tohka and the Spirits begged for Ellen to stop but she ignored their words and pierced Shido's heart as everyone were watching, thus finally killing him and forcing the Spirits to watch his death.

Kurumi about to undo the future.

During the confusion, Kurumi and her clones managed to escape as the mana of all Spirits who were sealed by Shido so far started to become dark, meaning that everything went according to Isaac's plans; all Spirits fell in despair and were becoming Inverse Spirits.

At last, there was a sharp alarm ringing throughout the town (the Spacequake alarm), but it was already too late. A huge tornado weltered around the school building, which had been reduced into rubble, magnifying the damage to the surrounding structures one after another. Then, a condensed jet-black light expanded radially from the center of the building. As far as one could see, the landscape had transformed into scorched earth and ending the lives of thousands in a second. As the Spirits' black energy started to grow even more, starting the Apocalypse, one of Kurumi clones managed to recover Shido's body during the process and the former tried to revive him with her the Fourth Bullet Dalet but it proved to be useless as it was impossible to bring someone back to life. Due to her failure, Kurumi fell in depression for having killed thousands only to know it was all in vain, she later looked at the world and saw the reality was about to end. During the climax of Westcott's plan (the end of the reality), Kurumi used her Sixth Bullet Vav to return to the past (days before the attack) before DEM could create such chaotic future where Isaac Westcott is the victorious.

Third Timeline

DEM's Full-Scale War Begins!

“	I will kill Itsuka Shidou. No matter how many times you go back. No matter how many times you reset the world. No matter how many times you revise history. I will do it so thoroughly so that you will never be able to overturn it. Well, try and fight it if you can ──Worst Spirit.	„
	~ Westcott's message to Kurumi Tokisaki.

Back at DEM HQ, Ellen and Artemisia were in a room filled with Nibecol clones waiting for Isaac Westcott to arrive from his company duty. During this time, Westcott's daughters annoyed Ellen by asking many questions to her, such as: “How was Otou-sama ("father" in Japanese) like when he was younger?" and many other nonsense. When Ellen asked Nibecol to be quiet but they answered back only to have the wizard calling them as monkeys. When Westcott arrived, Nibecol immediately rushed at him and said Ellen was hurting them and called her a person with the brain of a gorrila, much to Westcott's amusement, however, this time Ellen used her Territory to kill one of Westcott's daughters by squeezing her to death. For Westcott and Ellen, this degree does not fall under death. It was a sensation similar for them to lightly tap their fingertips against something. In fact, the rest of the Nibelcol did not lament over their companion’s annihilation, nor Isaac Westcott. The director then asked Ellen to calm down as he does not want to lose more allies. Westcott exposed a thin smile before walking towards where that piece of paper fell down on the floor reaching out to touch the object that was just a Nibelcol just a moment ago. The moment after that touch, the paper emitted out a faint light just before a girl suddenly appeared from within the sheet. It was the exact same Nibelcol that Ellen had strangled with her territory just earlier.

Westcott then go to the point and says that he is aware that Kurumi Tokisaki altered the timeline by returning to the past thanks to his omniscience granted by his Demon King Beelzebub, the omniscient Demon King that Westcott had stolen away from Nia months ago. Later, Westcott informs that Kurumi is awared of his plan to kill Shido Itsuka and force all Spirits go into Inverse Mode (Westcott's plan in killing during Kurumi's confession) and so the same plan is not going to work. During their conversation, Nibecol entered in their way and said Ellen was the reason why they failed, with this, the Wizard once again tried to the Nibecol clone but they hide themselves behind Westcott who was explaing that as long the Angel Zafkiel is on the hands of Kurumi Tokisaki, it will be impossible to take progress as Kurumi can always return to the past to change the future where DEM will be victorious. Having heard this, Ellen envisioned repeating an endless trial and error to avoid having a beloved from being slaughtered. Even the strongest Wizard Ellen was left shivering in fear. For Nightmare, Tokisaki Kurumi to have endured that kind of thing up until now, it was enough to sincerely respect her despite being an enemy.

As Westcott continued, he planned to end Kurumi's mission by showing the true strength of his company to make her give up on Shido Itsuka and her new "friends". Westcott suggested mobilizing all of DEM Industries’ resources to completely decimate Itsuka Shidou and added that even if Kurumi already knows what will happen, it will be to the extent of being absolutely impossible to prevent from occurring. In the process of this operation, he might start a war of full scale in Tenguu City and end the lives of millions but he doesn't show interest in the lives of civilians and considered a side-effect. Westcott then add that Kurumi's hopes and ideals, everything will become severed when he show the true force of his armada. After saying that, Westcott’s smile grew darker as more Nibecol clones arrived in the room through the vent of the office. Nibecol clones then showed a freshly decapitated head of a Kurumi Tokisaki and informed him that some clones of Kurumi Tokisaki were sneaking around DEM's territory. Westcott then gave his praise to Nibelcol and his daughter let out a cheerful and bashful “eh” sound. For Ellen, it might have even resembled a cute interaction between parent and child were it not for the blood from the severed head dripping on her hands. However, Nibecol continued and said that many of her clones managed to escape after listening to Westcott's plans, however, the director did not mind the fact as long as Zafkiel is in her hands, Kurumi will find out eventually what DEM is planning. Isaac then looks at the roof and asks if there are still clones of Kurumi listening to his words and ask them to send a message to their master, saying he will definitely kill Shido Itsuka and end their miserable lives. Later, Kurumi's shadows shaked in anger and left the room to inform to Ratatoskr that Isaac Westcott is coming with his armada to put an end to the war between DEM and Ratatoskr that has been happening for 3 decades.

The Final Battle Begins

Many days after Westcott declared war, the heroes spent days working in a plan to counter-attack Westcott and his armada that were regrouping from all over the world in United Kingdom to launch a full-assault to Tenguu City to put an end to Shido and Kurumi's lives. When the day had arrived, the DEM Industries had 30 space ships, tens thousands of Wizards, thousands of Bandersnatch and Nibelcol's clones, not to mention Ellen Mira Mathers and Artemisia Bell Ashcroft, two of the World's Strongest Wizards. Westcott then ordered his forces to charge at the enemy with full-force and leave no survivors. If someone of Ratatoskr's ranks survive, execute them or torture them to death and if a civilian witness his armada, shoot them down, no matter if they are women or children. When DEM fleet was near the town, Ratatoskr immediately rang the spacequake alarm to make all population of the city enter in the Anti-Spacequake shelter to reduce the number of civilian victims, however, Westcott was not amused and considered in sending troops to shoot all population of the town in the shelter to find Shido if he refuses to show up.

Despite Ratatoskr's efforts to stop Westcott's armada they had only 5 space ships and places of Tenguu City that were remodeled by them to become artillery bases, hundreds of Wizards who were outnumbered, plus the 10 Spirits and Mana Takamiya, a former Wizard from DEM Industries. Before the battle began, Origami and Mana revealed their plan to defeat the Bandersnatch; that is by defeating Artemisia and insert the jamming code in her brainwave implated by Westcott to rewrite her memories, which will supposedly disable the Ashcroft-Beta Realizers that the Bandersnatch units are using. When the DEM fleet arrived, Westcott gave no chances to truce as he had enough of Elliot Woodman and the war begins, with both sides at a stalemate until Isaac Westcott orders all units to sortie, and then Ratatoskr and DEM's army fought in the skies of Tenguu City, however, it took not so long for the battle go to the ground where Spirits, Wizards and Bandersnatchs fought each other in a bloody battle, resulting in many deaths and destruction below.

At the same time, Westcott orders the AST's HQ from the Japanese Anti-Spirit Team, to charge in to fight against the Spirits to support DEM Industries in this matter for the "greater good". However, Westcott ordered his soldiers to use AST as baits to distract the Spirits and Ratatoskr's Wizards to take the chance to shoot down the enemy. When one of the DEM soldiers targeted the AST by using them as baits, Mukuro (ironically, one of the Spirits they were trying to kill) saved the AST leader by redirecting the laser back to the DEM Wizard herself thus killing her, the AST then decided to ignore Westcott and Japan Ground Self Defense's orders and fight against DEM instead as they had enough of Westcott and DEM in their country. On the battlefield, Westcott watched the war while Mana, Origami, Mukuro and Yoshino went up against Artemisia, however, she was able to go up against them all while explaining DEM gave her power to fight them all. Things went worse when Nia told that Ellen was going over there to back her up, but Ellen then was stopped by Elliot Woodman himself, the leader of Ratatoskr, who was all young again, leaving her surprised as he was an old-man just a few hours ago. At another place, some of Westcott's Nibelcol were facing against Ratatoskr’s Wizards, which were ended up saved by Tohka and the Yamai siblings, and their target Shido. The Nibelcol immediately went to charge towards him, and while Tohka managed to obstruct several of them, one managed to pass through and head towards Shidou with intentions to kill him in Westcott's name but he was saved by Kurumi.

Shido and Kurumi surrounded by Nibelcol.

During the battle, Kurumi tells that she wanted to kill the First Spirit and change history so that Shido can live, but Shido rejected her plan since it would mean he would never meet Kurumi. Not to mention that if she kill Westcott, Ellen, Karen and Elliot in the past, he would never have known none of the Spirits. Thus he decided on a plan where Kurumi let him seal her powers and then use her time travel powers to go back 30 years ago and seal the First Spirit without killing Westcott and the others. Then he will go through history, until the day where he and Kurumi will meet again.

At this moment, a Nibelcol went to kill Kurumi but she was protected by eye-patch Kurumi instead, who then tells her to be honest to her heart before disappearing. Before Shido can finally seal Kurumi, a hand appeared from Kurumi’s chest, just like what Shidou saw happened at the rooftop when Kurumi pierced her hand towards the clone Kurumi back in Volume 3. But this time, it was not a hand that pierced through her, but a hand that came from inside of her and was trying to get out. Then after a moment, the First Spirit who was summoned by Isaac and his friends appeared, who was revealed to be Reine Murasame, the mother of Shido who had her loved one killed by Westcott's hands. The First Spirit--Reine then thanks Kurumi for being her best friend until the end after all.

Battle with Shido

“	It was finally revealed. Westcott was not abnormal, not even insane. He was an extreme human being to the greatest extent. However, in terms of ethics he stood from a completely different from all humanity, with a viewpoint on life and death incompatible with other human beings. He was a human. But... What makes a human and a monster?	„
	~ The author narrating Shido's thoughts about Westcott.

As the battle continued following Kurumi's death by the hands of Mio Takamiya, also known as the First Spirit, Westcott then arrives with the Nibelcol and Beelzebub in hand and watch the battle between the Spirits. At this moment, Mio Takamiya, also known as the First Spiriti, summons Ain Soph Aur and giant flower appears in the air. And from the center, the silhouette of a young lady as if praying together is standing there, who turns out to be Mayuri (a non-canon Spirit from the film universe). As Mio utters the word “bloom”, death begins to spread indiscriminately. As the DEM forces witnesses Mio's power far out of their imagination appear, the crew of DEM's flagship enter in state of panic, but Isaac Westcott laughed madly as he witnessed the power of the "Gods". In the surrounding area, whether "Nibelcole", "Bandersnatch", the Wizards or even the giant warship, anything that touches the bright particles emanating from Ain Soph Aur disappears like smoke.

After that, Westcott and his ship were caught by the light, which resulted in the downfall of the DEM flagship. Yet, somehow, Westcott survived the explosion of his ship and planned to attack Shido Itsuka while he was alone. Waiting for the moment, Westcott used the chance that Shido was making his way towards Mio on the other side of the battlefield and summoned dozens of Nibelcol around him. When Shido prepared to "flirt" with Nibelcol, Westcott showed up and prevented him from doing so (considering his daughters have the personality of school girls). Upon seeing Shido, he proceeded to declare his final battle with him to decide who is more qualified for the power of the Spirits.

As they prepared to fight, Westcott taunted Shido about his death by his hands in the past. This caused the hero to lose his cool and fill his heart with hatred (something Westcott always desired). When Westcott finished, he looked at his destroyed ship from distance and mentioned that his crew of hundreds of DEM officers didn't survive, but added it was actually fantastic to see Mio taking down his ship and killing all his subordinates. Then, Westcott ask Shido's help to take down Mio Takamiya as his forces and himself are not match for the First of All Spirits. Obviously, Shido refuses and then the director claims he will kill Shido first and steal the mana of all Spirits he sealed so far in order to gain absolute power.

Starting their battle, Westcott summons his daughters to prevent the hero from escaping. In response, Shido summons the Angels of all Spirits he had and prepared to seal the fate of Westcott. Meanwhile, on distance the final battle between Ellen and Elliot had ended with a draw. However, after Ellen lost her consciouness, Elliot lost his life due to the exaggerated amount of magical power he used. Even from distance, Westcott could sense the life of Elliot, his best friend, fading away. In response to this, Westcott felt a little of guilty for losing his childhood friend but then he added that he was a fool who deserved death. Enraged by Westcott's lack of love, Shido charges at him and fires a shockwave of light at him, but he quickly cancelled his attack with Beelzebub's book.

Westcott then counter-attacks and gave orders to Nibelcol to attack Shido, only to be defeated and humilliated in front of him. Seeing that, Westcott wipes out their existence and calmly cast another wave of Nibelcol, whom had surrounded Shidou with a queue formation; the group of Nibelcol began to leap to attack Shidou one by one. When Shido tried to seal their powers with a kiss again, he noticed Westcott blindfolded their vision to erase their fears from being kissed. Yet, Shido repelled most of their attacks, leaving Westcott amused as Shido did his best to struggle. Seeing himself in danger, Shido used Metraton Angel to create an artificial sun and disappear from Westcott and Nibelcol's sight. When the evil Spirits began to look for Shido, Westcott was attacked by one of the Nibelcol, who revealed to be Shido disguised. However, no matter what he did, Westcott easily predicted his move and taunted his negligence. Using his strategy, Westcott summoned Nibelcol behind and Shido and made them punch him in his abdomen, injuring the hero and weakning his physical body. While Westcott watched Shido coughing blood in amusement, he was asked why he wants the power of the Spirits by the former. Westcott then replies that he is doing all of that for the sake of creating a new world by rewriting the real universe with Deus (Mio Takamiya)'s world of Spirits in order to have revenge on the human race that killed his family.

After that, he gave Shido a long speech of that good and evil are just a point of view as long he is doing good things in the eyes of his own people; the methods and ways are meaningless. At that point, Shido discovered that Westcott was not a monster but a human being to the greatest extent, it was only him morals and sense of ethic that were screwed up. 

Westcott then prepared to use his hand to rip off Shido's heart but he was stopped by Miku and Natsumi, who arrived in time. Gaining new allies, Shido proposed to defeat Westcott as quickly as possible and help the others to defeat the Spirit of Origin (First Spirit/Mio Takamiya) that has appeared. When Westcott recovered his senses, he smiled sadistically as he thanked Miku and Natsumi for coming for him since he will be able to rip off their Sephirah Crystals along with Shido's mana. While Shido, Miku and Natsumi were discussing a plan to defeat Westcott, the latter summoned more than 100 Nibelcols and ordered them to rip off their hearts. With the help of the Spirits, Shido managed to summon the Halvanhelev (the Throne of Sandalphon of Tohka). Shido then lifted the sword towards Westcott’s direction... Instead of running away, Westcott was too fascinated by the beauty of that attack and laughed madly as he let himself be hit by the wave of power. The excitement of that power becoming his own as long as he took away the Sephira Crystals, the excitement of his imminent death, at that moment Westcott’s mind was overflowing with pleasure. However, Westcott remembered that he wasn't immortal yet and decided to use the hundreds Nibelcols around him as meat shields. While they were being used as shields, Westcott took this chance to escape from the explosion but was caught by the attack with heavy injuries.

Westcott then laughed again as he knew that Shido used all his powers but all proved to be useless against him. As Westcott was celebrating his victory, Shido was preparing to give his ultimate and last energy blast. As Westcott prepared to deny his attack, he couldn't recognize the name of his ability since he was speaking in another language. While examining over the entire possible enemy powers that Westcott was aware of being able to be used in the instance of a chance opportunity, Shido's torrent of Spirit mana swallowed Westcott, who was already exhausted from Halvanhelev's previous attack.

The attack destroyed most of Westcott's bones and disabled him from fighting further. While most thought he wad dead, it was revealed that he had survived and began to curse himself for losing in such boring way. Seeing that Westcott, his killer, was defenseless, Shido proceeded to grab kill Westcott as he accepted his fate. Yet, he remembered that killing a defenseless person, no matter how cruel, would make him just like Westcott, the person who brought death and sorrow for millions. Instead of finishing him off, Shido summoned Michael's Angel to destroy Beelzebub's book. 

Finding his behavior as odd, Westcott questioned why he is letting him live. The hero replied that he will pay for his sins in the living world while calling him a loser. The evil director found that a pity as he was interested in the feeling of death. However, just as Westcott began to laugh, the world became black and white. The next moment revealed that Mio Takamiya was extracting the Sephira Crystals of all Spirits in the world, killing them on the process. Following the defeat of Westcott, Shido and Tohka, the only Spirits who managed to survive, proceeded to attack Mio and finish this battle. However, the battle ended in Tohka's death, and forced Shido to use the power of a clone of Kurumi Tokisaki, to go back in time 30 hours ago to change the future where all Spirits were killed by Mio.

Fourth Timeline

Westcott's Assassination

In the DEM branch, Westcott discovers that Shido altered the future once again using his Beelzebub's omniscience. Discovering this, Westcott then orders all his forces from world to gather in United Kingdom to launch a full-attack to Tenguu City.

Following the events of Westcott's declaration of war to Ratatoskr, Shido managed to return in time before Westcott and the DEM arrived in Tenguu City. This allowed him to go on a date with Reine Murasame (the fragmental Spirit of Mio Takamiya) in order to make her fall in love with over Shinji Takamiya (his previous persona). However, the sealing of Reine's powers fail and DEM shows up. Using Westcott's omniscience, the DEM was able to discover that Shido altered the timeline once again using Kurumi's powers. Aware of this, Westcott, Artemishia and Ellen regrouped in the flagship and prepared to strike the Spirits and Ratatoskr emotionally rather than giving a direct combat. However, Ratatoskr and their allies began the attack, once again turning the town into a war zone. 

Tohka, Origami and Miku facing Westcott and the Bandersnatchs

As Mio saw the man who killed Shinji approaching with his minions, she goes off to fight the army of Wizards and Bandersnatchs droids. While Westcott watched the conflict, he sent troops to the underground facility of Tenguu City, AST Base and a musical event to seek the friends of the heroes. After many minutes, Westcott had a group of teenagers and children in his hands and was willing to trade the lives of their friends for the Sephirah Crystals of all Spirits combined. Not only civilians but also the Wizards from AST who were Origami's friends. Westcott then snap his fingers and finish the transmission while saying they have only a few minutes to decide.

Obviously, the heroes thought he was lying and then he ordered one of his Bandersnatchs to kill one of the hostages. It turned out the hostages were students from Raizen High School and betrayed Wizards from AST, and soon afterwards he once again order his robots to kill some of the hostages, this time, Ryouko, Mikie, Asakura Hiyori, Ai, Mai and Mii as well as a group of dozens of children and teenagers. Seeing this, Mukuro creates dimensional holes and teleports Origami, Miku and Tohka at those locations to protect the civilians, ending the attempted mass-murder in a matter of seconds.

However, while the Spirits were busy saving the hostages, Westcott, Artemishia and Ellen went personally to Fraxinus to kill Elliot Woodman and the rest of the crew. During their invasion, Westcott once again massacred hundreds of officers and members of the staff. Noticing that the Spirits are coming to stop him, he summons an army of thousands of Nibelcols to fight his enemies and destroy the ship from outside. While Westcott invaded the ship alongside Ellen and Artemisia, Shido, Kotori and Mana arrived and prepared to fight the trio while the rest went to fight DEM's force.

While Westcott was fighting Shido, Woodman watched their fight and ordered Karen, to prepare his CR-Unit, Odin, to join the battle since he knew Shido's defeat is inevitable. After a long time fighting, Westcott discovered an opening in the boy's defenses and knocked him. With eager to get Shido's powers, Westcott prepared to impalw him with his own hand. However, Kurumi Tokisaki appeared and impaled his chest, ripping off his Sephira Crystal he stole from Nia's inversion. Then Kurumi's clones unloaded a series of ammunition that caused severe injuries to Westcott.

Westcott then falls to the floor, lifeless, as Kurumi helps Shido to get up and prepares to transfer his crystal and her personality to one of her clones to keep it in safety. Seeing Westcott in the brink of death, Ellen and Artemishia carried his body away. However, it was later revealed he faked his death so he could strike by surprise in a near future. As Kurumi prepared to use Beelzebub, Mio comes back from the battle and declares that she will once again kill all Spirits and erase the memories of Shido to bring back her loved Shinji Takamiya.

As Westcott was faking his death, he asked Ellen where her ship was, GOETIA, and she immediately replied it was attached to Fraxinus. He then smiled maliciously as he declared everything happened according to his plan.

Becoming the Second Spirit of Origin

While Shido, Shinji, Mio and Reine were inside of Ain Soph to have their "special date" in an attempt to seal them both, Westcott prepared to transfer all of Mio's mana to his own body using GOETIA as the source of energy. When Shido and Mio left from the Ain Soph, they were caught by surprise by a magical circle surrouding them. In the middle of their conversation, the scenery around suddenly showed disruptions, Mio and Reine acknowledged that someone was using the Spirit Formula outside. 30 years ago, this was the ritual used to summon the Spirits to the human world. But to perform it, one has to choose a place that has the Spirit Core. And that place is the centre of Eurasia. Currently, Mio was also the incarnation of that Spirit Core. For a Spirit Core to bloom up naturally it would take hundreds of thousands of years, and the current Spirit Formula was not performed in the normal way. Westcott used Goetia as a replica for the Spirit Core. «Goetia» was initially Ellen’s private battleship, but by itself it is also a huge CR-Unit. By lying down inside «Goetia» and performing the Spirit Formula, Westcott had converged the Mana flow into his own body.

After a long and painful transference of power, Westcott managed to drain very single drop of Mio's power and became the new Spirit of Origin, the Second Spirit of Origin. However, since his heart was pure evil, the power of the Spirits declared him as an Inverse Spirit of Origin, the Source of All Evil in Qliphoth Tree. Seeing Westcott becoming the source of all evil in the universe, Mio then asks for Shido's help as Reine and Shinji disappears forever. Mio then held Shido's hands, knowing this mission might end their lives.

Mio then summoned the Celestial Knights to test Westcott's powers but they were instantly vaporized. Seeing the two were about to attack him, Westcott said he is going to be busy rewriting the universe's laws and so he sent a small sphere of energy to Ellen and Artemishia, strengthening their power and physical abilities.

Final Confrontation

Without wasting his time, Westcott ramdonly used his powers to test the limits of his own energy. In the darken sky where the setting sun had already vanished into the horizon, Westcott's light swirled coiled and swirled as it converged onto a single point, twisting the reality and space around him. Discovering his limits, Westcott claimed he is now equal to Deus and nothing can stop him now as he have the power of all Spirits in the universe, making himself the strongest being in the existence, the most common traces of his powers were among omniscience (infinite knowledge), omnipotence (unlimited power), omnipresence (present everywhere), immortality, divine simplicity and control over all aspects of creation and life itself.

Scared of the supernatural power stolen by Westcott, Tohka tried to kill him with a wave of reiryouku. However, the slash, which could cleave open any solid impregnatable fortress, dissolved into the air upon making contact with the light radiating from Westcott. Before she could do anything else, Ellen and Artemisia rushed at the group of Spirits and fought them in a final battle. In an instant, Origami and Mana screamed as their bodies were repelled backwards. An instantaneous attack faster than what the eye could follow. Despite the two of them already having assumed a defensive stance, their weaponry and armored arm respectively were beautifully torn down. Artemisia then tried to cut the head of Tohka but she blocked her sword with her Sandalphon, yet before she could strike back, Artemisia, with the energy of Westcott, kicked Tohka meters away, forcing the Spirit to kick off against the sky. Naturally, Artemisia followed the Spirit but before they could fight again, Mio and Shido came out from the sky, calling the attention of the evil trio. Shido then manifested the Angel Sandalphon in his hand while pointing it at Westcott but the overwhelming pressure from Westcott's energy caused the hero to see illusions of his skin breaking apart into dust, making him confirm that a being that is not a Spirit will easily have their souls dragged out of their bodies just by looking at the new Second Spirit of Origin.

Westcott then thanked Shido for holding off Mio in their special date until he could finish the Spirit Formula and transfer all her powers to his body, making him the new Spirit of Origin. Even with his guard on alert, Shido felt his breath begin to clog as Westcott summoned a Demon King behind him. Floating behind Westcott, a huge “tree” had appeared. A jet-black tree with branches that shaded the sky and roots that dredged towards the earth. It’s epidermis resembled decaying rotten wood as it filled the air with an ominous feeling of suffocation. The Demon King from nightmares emerged as if spreading despair to everyone who gazed at it, Westcott then laughed loudly and like conductor waved his hands while declaring with an intoxicated expression the name of the Demon King, Belial. In that instant, the jet-black tree began to squirm like the movements from a developing fetus. Its branches began to expand out to the horizon as its roots turned and pointed to the ground. At the same time, another landscape began to form in the sky around the huge tree. Everyone recognized this sight as it felt the same as the monochrome space created by Mio's Ain Soph, the sensation of the “neighboring world” gradually eroding this world. Westcott then declared he would not waste his time playing with them and prepared himself to rewrite the dimensional space of all universe to create his own world and replace all life with a dystopia world where magus will come back to life to rule over all reality as the only-superior race of the universe.

At that moment, the Mio summoned her Ain Soph and created a similar tree, but a tree of light, unlike Westcott's that is a tree of darkness and death. Ain Soph extended out its branches and roots to entangled Belial in order to pin it down. Ain Soph and Belial intertwined intricately, enveloping the surrounding area like a huge bird cage. The two worlds vying for development collided against each other, staining the surrounding scenery with noise. Westcott then praised Mio for her efforts but said it was useless as the Inverse Forms of the Angels are way superior. Westcott then raised his hand and twisted a part of the dimension in his hands to force the release of Belial. At the same time, Mio asked for the help of all Spirits to protect the world by lending their Angels to Mio to form one single divine attack to break through Westcott's defenses. The Spirits all responded to Shido's command as they each kicked off the exterior of Fraxinus and rushed towards Westcott. 

However, Westcott wouldn't just wait by silently and tried to use the squirming branches from Belial to shoot down the Spirits at a tremendous speed. Artemisia and Ellen, both given power by Westcott, intercepted the Spirits. Their laser swords were weaved with a dense magic as they traversed in a speed faster than the human eye could follow. Despite this, the Spirits who had regained their full strength wouldn't be killed so easily. Origami and Mana suppressed the DEM wizards as the rest of the Spirits used that opportunity to avoid the branches from Belial. Strengthened by the Angels of all Spirits, the Spirits fired a laser beam with the combined might of everyone as the night sky turned bright red. Although Westcott defended himself with a wall of reiryoku from Belial, it could be seen that damage was gradually beginning to accumulate despite still remaining unscathed. 

Impressed by the attack of all Spirits combined, Westcott summoned Athiel (Extreme Altar of Death) and a huge sphere on the size of a 50km meteor appeared in the sky above Westcott’s head. Following Westcott command, ripples began to form on the surface of the sphere like a flower bud beginning to bloom. From that center, countless particles of darkness poured down towards the Spirits and all the town of Tenguu City. The grains of darkness released from the huge black flower Athiel poured down towards the Spirits like countless particles of drifting pollen, killing the last soldiers of DEM and thousand civilians. Westcott revealed those dark particles were a representation of "death", an instant death attack that would snatch away the life of its target with a mere contact. The Spirits didn’t attempt to rebound or defend as they quickly leaped out the way while the evil magician used this opportunity to bring more destruction and death around the area.

Origami and Mana, who were fighting Artemisia and Ellen, were obstructed by their opponents and forced to make a delayed escape. In response to this, Mio tried to summon Ain Soph Aur to counteract Athiel before it could kill Origami and Mana. Yet, it was too late for both girls, but before they could be killed by the particles, Maria Arusu and hundreds of her clones protected the Spirits and Wizards as they danced in the air, before heading towards Athiel. 

As Shido saw this opportunity to finish Westcott, he flew towards towards Westcott who was busy trying to convert the world into his paradise, making billions victims. Ellen and Artemisia, who noticed his movements, tried to stop him alongside the countless branches of Belial that were squirming like tentacles. The Spirits lined up around him deflected back the Wizards' laser swords and dispelled the incoming branches in order to clear a pathway. Making his to Westcott, who was aware of his incoming attack, released numerous laser beams at the boy but he missed all. Seeing this chance to end this battle before more millions could die. Shido then summoned the power of all Angels in his hand as he prepared to punch the magician. Westcott widened his eyes in joy and excitement to meet his death and defeat as his omniscience had already foresaw the future. 

With the combined powers of all Kabbalah tree in his fist, Shido smashed Westcott's face, making the entire continent tremble like an earthquake. At the same time Westcott let out an anguished cry, the huge tree standing behind him and the overlooking flower above both let out a dull sound. The space fought against with Ain Soph had begun to distort and collapse, putting an end to the two Demon Kings. Although Westcott had possessed the power of the Spirit of Origin, it was impossible to handle that lightly as he is just a magician who don't have control over the Demon Kings yet. Westcott's falls to the floor and his new form begins to crack, returning him to his normal form. While everyone were celebrating their victory after saving the universe, Westcott laughed as he said he didn't stop anything but only brought the end of all life on the planet. Westcott then summoned Qemetiel by spelling its name and a torrent of mana surrounded his body like a storm and then claimed that with his injuries, he could no longer hold the power of the Demon King with perfection, and it would cause a worldwide explosion that would take every single living being on the globe with him (with the planet itself). Meanwhile, Mio is astonished and could think in nothing to stop the magician from destroying the world with him.

Darkness gathered in front of Westcott and formed the shape of a seed. Shido tried to escape but his body was bounded by that seed and could not move. Before he could jump from the seed, Shido realized if he jumps from that seed, the entire zone in kilometers will be erased alongside the Spirits. Meanwhile, the black seed as if germinating, was spreading darkness out into the area, marking the Spirits with death. However, before the darkness could engulf Shido, Mio released him and saved the hero. Before everything, she explained the power of Qemetiel is out of control and if it continues another catastrophe similar to the First Spacequake that happened 30 years ago will happen again but in a worldwide scale. Mio then remembered her life with Shinji and said she loved Shido before saying a final goodbye before pushing him out of the storm of darkness and mana. No, not just Shidou. The other Spirits along with Mana, also got pulled away by countless branches. As Ain Soph pulled everyone away, it gradually changed its gigantic form, just like before when it wrapped around Mio and Shidou, it then covered itself around Shidou and Fraxinus.

Inside of the storm of mana, Mio confronted Westcott in a final meeting. Westcott then said it was a beautiful moment of affection but right now he only wants to delete Shido purely out of envy due to his relationship with Mio, the Spirit he is in love with. Westcott then questioned where he did wrong in his life; from the moment he killed his parents, created the Spirit Formula and summoned her to the world. After seeing that Westcott was living in misery his entire life, af if she was trying to "comfort" him a little by saying if his love for her is one of the causes of his misery, she took this chance to say she would never choose a person so monstrous like him. Westcott then laughed while shocked with the revelation the Spirit he loved for so long never would accept him. With their final conversation finished, Westcott summoned the Black Seed of Qemetiel in his hands as Mio summoned her last Angel, Ain. A moment after, the forces of void and void collided against each other, causing a huge explosion of energy that destroyed everything in thousand kilometers.

Ultimate Demise

“	What... it was so simple... wasn’t it? Fill them with despair...	„
	~ Westcott's last thoughts.

After Mio successively returned Belial's energy back to Westcott, he was hit by the explosion of Ain and Belial's energy, causing his body to be destroyed. When the dust disappeared, it was revealed he had survived but only his torso and head were intact. While he was on the floor, he noticed his Demon Kings are now long gone, and even if he somehow regenerate his own body using a Realizer, there is no point in living since his plans to rewrite the reality were ruined by Mio and Shido. He then thought about suicide but then he realized that he already tried to kill himself with the rest of the world but failed to do so. But what truly caused him to give up was the fact that Mio was dead and refused to be with him.

Moments later, Ellen, his childhood friend, approached him while preparing to take him to a medical realizer. However, he refused as he saw Elliot and Karen approaching. Seeing Elliot and Karen there, Ellen begged for them to save Westcott but the latter refused. At that point, even Elliot knew Westcott's only wish was to die. Westcott then asks if he came to laugh at him but his friend calmly reply saying he was there to see him die. Westcott began to blame himself for asking such idiot question as they were always friends and both were men who were rejected by the same woman (Mio Takamiya).

Mio's death.

Just as Westcott began to feel the hand of the Angel of Death about to get his soul to bring it to Hell, he remembered a strange feeling of joy and pleasure. When he witnessed Ellen, Karen and Elliot's sorrow for losing their childhood friend, Westcott remembered the day his mother died, the day he could feel sorrow for the first time in the face of so many people. The looks of his friends, and the fact that he was the one molding these facial expressions, the fact that he was at the center of their despair, was absolutely wonderful and comfortable for him.

Westcott then dies in "ecstatic excitement" as the Angel of Death (shinigami) reaches him, turning his body into dust and ending his reign of terror once and for all. This time, for good. As such, he finally gets his eternal comeuppance for toying with God and Devil's power; and his soul is dragged into the depths of the Hebrew Hell forever.

Following his death, the Sephira/Qlipha Crystal he had inside of his body is left behind right where he died. Unfortunately, his suicidal move to take the rest of the world with him ended the life of Mio Takamiya, who died soon afterwards in the arms of Shido. However, with Westcott dead, Mio is finally free from her hatred that kept her alive for 3 decades since the day Westcott summoned her in the world. Accepting her fate, Mio goes to the Afterlife, where she finally meets her long lost-lover, Shinji Takamiya, the boy who was murdered by Westcott almost three decades ago. The couple then hug each other and disappears in the afterlife, happy now they can move on.

Even after his death, his legacy continued to live for countless years. In addition, with his death, now there are only 3 genuine mages left in the world: Elliot, Karen and Ellen.

Parallel Timeline

Tohka after she became Beast.

In a parallel timeline where the events of the original timeline changed slightly, Westcott successfully achieved one of his objectives through the hands of Beast. After every Spirit was sealed by Shido, the DEM Industries launched an attack in Tenguu City with the solo purpose of killing Shido so Westcott could make every Spirit go into Inverse Form. As the battle raged on, Westcott managed to impale Shido and ripped his heart off while forcing the other Spirits to watch. Witnessing Shido being murdered, Tohka fell into despair and lost her sanity, becoming Beast. She then proceeded to kill all every Spirit nearby, including Westcott and his subordinates.

After she absorbed all Angels of her fallen friends, she launched a cataclysmic event upon the world, resulting in the destruction of the entire world and killing billions. The world was ravaged by the power of Spirit, however, many people still survived. The story has spread far away from Japan, and not only in lands directly damaged by Tohka, many people have moved underground to continue living. But the world was bigger than Tohka thought and humans are more resilient than Tohka thought.

While Westcott did not achieve his primary goal of becoming the Spirit of Origin to rewrite the reality where he rules over a tortured world controlled by Magicians, Westcott still had success in killing Shido and force every Spirit to go Inverse, however, before the Spirits sealed could Invert, Tohka became the only threat to the world and nearly wiped out the humanity that Westcott so longed to erase and the "delicious" suffering he wanted to spread across the world was delivered with success.

Post-Death

Aftermath and Legacy

Ellen after forgetting everything about DEM and Westcott.

One year later after Westcott's death, the world changed completely. After the final battle, Ellen Mira Mathers, who had lost Westcott right front of her eyes, completely lost her memories and knowledge about DEM and Westcott after waking up from a coma. Although the reasons were unclear, after waking up Ellen showed no malice or hostility and was only happy to be reunited with Woodman and Karen. Shido brought the possibility of her losing her memories in shock of Westcott’s death or she had erased her own memories with the Realizer Manifestation Device because she could not endure the fact she lost her best friend. In another bizarre theory, Shido thought Westcott arranged for Ellen to lose her memories at the same time as his death because he wanted her to forget everything bad she did for him so she could have a happy life beside Elliot and her sister, Karen Nora Mathers.

Aside from the death count, the DEM kidnapped many children like Mana, and made them into soldiers of DEM. Wizards with powers to control over magi-tech. Unknown to mankind, those children were most orphans who lost their parents on the spacequakes and were children with high potential to control Realizers and CR-Units (most of the Japanese AST are composed by girls who lost loved ones to the Spirits in other spacequakes, confirming this theory). Due to the high altruism of Ratatoskr, it can be said that the Elliot Woodman helped to free all those innocents who were brainwashed to become mindless soldiers and suicidal child soldiers.

With Westcott dead, the DEM lost its central figure of authority and its military was completely divided between Westcott's Supporters and Anti-Isaac Factions. The DEM, which had lost Westcott’s strong central pull and influence, was in the midst of internal strife even after a year due to the anti-Westcott factions that continued to increase inside of their ranks as the most loyal officers and directors had to struggle their position in the leadership of the company, causing the company to slowly fall in ruins as Europe was being freed from their influence.

However, with Westcott's death, all nations of the world that depended on DEM's Realizers, suffered from great economic, financial, military and educational crisis. Westcott was the substantial top of the manufacturers (DEM) who were the only ones that could produce the Realizer in the entire world. Realizers were basically small chips made of magi-tech that could turn everything impossible in reality, such as allowing people to use magical powers, increasing the military in all continents and obviously, leading to more wars. With that said, it can be confirmed that most of all nations of the globe had their powers reduced, leading the globe to a possibly worldwide crisis, unless Ratatoskr and Asgard Electronics took over, replacing the role of DEM but in a more pacifist way. As such, without the Realizers to combat the crime, the police forces of the world suffered a great loss in their power, allowing the crime rate to increase. However, this opened other options for mankind to deal with their own evil without using power from a foreign corporation whose had almost total control over the governments thanks to DEM's influence in politics (as seen in Volume 5 where Sir Westcott had direct contact with the Prime Japanese Minister Saeki). Even so, the super soldiers created by Westcott, the Wizards, continued to exist and would be kept for the military of the world's governments for the next years to come. Due to Westcott's arrogance and cruelty, just a few people mourned for his death as seen with Elliot, Ellen and Karen, whom cried at the moment of his death. It's unknown how the world's leaders, popular figures and worldwide media reacted to his death.

Much later, Artemisia Bell Ashcroft also lost memories of her time during DEM and awakened months later. When she was speaking with Ryouko, she said she can't remember anything related to DEM as if she had awaken from a dream. Even so, she stated she could remember fighting Origami in space. Since she left DEM she was attending university and studying psychology with her friends of Special Sorcery Service. Ironically, Milly, one of DEM's engineers working to AST in Tenguu City also stated to have lost memories of joining DEM and questioned why she would join a company full of villains; Milly was a low engineer with small importance in the company so it's unknown why Westcott would install a Realizer in her brain as well.

Consequently, after his death that also lead to the demise of Mio Takamiya, the First Spirit he created, all Spirits ceased to exist, returning the sealed Spirits becoming normal humans again and living a normal life in the Japanese town of Tenguu City. In the same town, Ellen Mira Mathers who had forgot everything about Westcott, got a pity job at Ratatoskr and was replacing Reine’s old job as deputy teacher at Raizen High School. Due to her new job, now she has to deal with the Aii, Mai Mii trio that sexually harass her on a daily basis. 

Days later, Shido thought he could revive Tohka using the Spirit Formula, books and reports of Westcott he wrote 31 years ago but for Kurumi it was just an empty idea. In the first place, Isaac Westcott was the only person in the world to arrive at the Spirit Formula. The basic theory behind this technique was not known even to his former comrades. In other words, the Spirit Formula was impossible to be reproduced after his death. It became a so-called lost technology, making the revival or creation of any further Spirit impossible.

Tohka and Shido meet again in the last moments of the series.

However, it turns out Tohka was later brought back to life thanks to the machinations of the Will of the World, a fragment of Phantom [Reine Murasame] that continued watching over the world, who allowed an alternative version of Tohka called Beast to travel to another parallel Earth where she met her redemption by meeting Shido and returning to her senses. After Beast returned to her world, she met the Kurumi Tokisaki of her world that offered her a chance to undo the timeline she destroyed and revert everything back to normal to a place where she could avoid Shido's death by the hands of Westcott. The aftermatch is not shown but it is implied Tohka accepted the offer and changed her timeline with the help of Kurumi, thus avoiding the Bad End. 

After the battle of Beast against the Sealed Spirits, the mana created by their combat in the planet was enough to bring Tohka back to life in the physical world that was said to be impossible. As Shido was walking down a path he once walked together with Tohka and Tenka in the past, he meet a girl and ask for her name, the girl revealed to be Tohka Yatogami, a person whose name was given by a precious person. With Tohka revived, the DEM falling, the Spirits gone and the destruction of all Realizers that became a fundamental technology of humanity, the world was now finally at peace and free from all evil brought by Westcott forever.
