Villain Overview
It felt so good... The day I lost my little friend. Ahh, how pleasant it was the sorrow I felt when I lost my mother. It was so delicious. That joy... And when that day had arrived... The day that humans showed their fangs to us and put my race to the sword... Ahh, I understand. It can be done this way as well. Bringing sorrow, despair and sadness to other people. Unforgivable. Absolutely unforgivable. Humans. You all started this. So I'm not one to blame. Thank you for giving me the opportunity to retaliate. Thank you for giving me a reason for slaughtering you. Thank you for giving me a motive for revenge. T͏h̢aǹk̀ ͠yo͞u for ̸makìng me ͠a ̶v͢i͟ct̸i̶m͡.
~ Westcott thanking humans for giving him a reason for revenge

Born as Ike and later known as Sir Isaac Ray Peram Westcott (in Japanese: アイザック・レイ・ペラム・ウェストコット, Aizakku Rei Peramu Uesutokotto), or simply known as Isaac Ray Peram Westcott or Isaac Westcott (among many other alias), is the main antagonist of the Date A Live franchise; he was introduced as the overarching antagonist of the second half of the first season (volume 1-4) and later introduced as the Big Bad for the rest of the series in other medias; from the novels, side stories, mangas, web comics, games and animation adaptation.

He is an evil and ruthless British man who works as the corrupt managing director and founder of the largest company in the world, Deus.Ex.Machina Industries and rules it with a fascist iron fist. Westcott adopted the concept of racism and supremacy as his aim is to unite "racially desirable" mages as comrades, while excluding those deemed either to be religious dissidents, physically or intellectually inferior, or of a foreign race, in other words, all humans; including men, women, children, and infants. Westcott is a creepy and sinister sadomasoquist who loves feeling negative emotions, because of that he is a person who has a abnormal mind or, in other words, a "cruel and twisted" businessman with the diabolical ambition of killing and enslaving all humans of reality and creating a new world in his image by destroying the current way of life on Earth and replace the civilization with a nazi-like utopia where mages will rule as the master race with him as the central figure of authoritarianism and "salvation".

While he often express his feeling of revenge towards mankind for exterminating his people, his true desires is mostly related to his insane behavior and obsession with negative emotions. As the most vile mage to have ever existed, Westcott was deeply obsessed with death as it causes living being to feel despair sadness and sorrow, having found those feelings to be the most (and possibly the only) enjoyable emotion for him, whether it be inflicting despair unto others, or suffering from despair wholeheartedly. This made him extremely dangerous, as he wished to make the whole world feel his pain and suffering. As such, Westcott finds pleasure, happiness and even joy in losing important people and things he loves dearly, even going to the point to form friendships only to wait and see them dying to feel the suffering (joy) of pain.

Westcott is also a person who represents the very depressive side of mankind, a person who loves living in despair and depression. It was later revealed he suffers from self-defeating personality disorder, he represents the total opposite of Shido Itsuka and Elliot Woodman, who represents life and hope, as well as altruism and humanitarianism. Isaac is a person who introduces the Hedgehog's Dillema in the story as Westcott and his friends have different wills and dreams, which forced his fellows to struggle between themselves (mostly between Westcott and Elliot) creates a world of despair and loneliness in his mind. For him, being alive is the same as being in pain, and he do his best to make the world a proper place for his depression and sorrow.

Due to his role in the Volume 5 onwards, as well on the game universe and in manga series, he is highly considered the most vile and vicious villain of Date A Live franchise and the darkest villain created by Kouchi Tachibana in comparison to other villains from his works who are more played for laughs and/or are sympathetic. In addition, he is highly considered to be one of the evilest and well-written villains from Light Novels media around. This is due to the fact that most of villains from LNs are Arc Villains with little of influence in the story with its Big Bad appearing only a few arcs. Westcott, on the other hand, is related too 100% of all events happening in the story and is an antagonist with the longest arc known in Light Novels so far. In-Universe, while most other villainous humans qualify as Well-Intentioned Extremists because they think what they do, no matter how evil, is all to save mankind from the Spirits while displaying comedy; Isaac is a living being who has the full reasoning of what he does, and commits all of his atrocities expressly out of his own free will. Westcott was first introduced as an antagonist who loves committing all kinds of atrocities but later it was revealed he believes himself to be not as "bad guy" but rather as "hero" to the point of hypocrisy as he believes all humans are evil by nature and deserves to be destroyed, no matter their race or age. He often will use this excuse to find reason in his own crimes. His goals and persona are heavily based in the real-life dictator Adolf Hitler as he wishes the total extermination of mankind through extermination and genocide of an entire race and to put his race as the masters to rule the world.

He was voiced by Ryōtarō Okiayu in the Japanese version of the anime, and Alex Organ in the English version (who also voices Shogo Makishima and the Doctor (Black Butler)), both of whom voiced Kaku.


Isaac Wescott

Sir Isaac Ray Peram Westcott's full view.

While it was unknown for a while, the very first novels implied he had around 30 years old but it was later revealed he has 49 years old. Westcott a tall man with smooth and long dark ash blonde/white hair, pale skin and sharp dark blue eyes as if a knife was used to cut a slit on his face. He is always wearing a black suit, with black social shoes, black social pants, and a white tie. He is known to be of British origin but speaks fluent Japanese. He is described as a very scary man by Origami.

He is described as being around 30 years old, but Origami notes that he gives off the impression of an experienced veteran. Mr. Woodman also states that he left the DEM 30 years ago due to a fallout with Westcott. Can't rule out the possibility that Westcott is using magic to keep the youthful appearance, after all, it was said Elliot left the DEM Industries 30 years ago, and many of the characters in the series refer to him as a person with 30 years old. There is a possibility that Westcott is using technological-magic (a small piece of Magi-Tech known as Realizer) on himself to not grow old like Elliot Baldwin Woodman is doing to stay alive due to his age.

After his fight against Woodman, Westcott had one of his arms severed in the conflict and is currently undergoing Realizer treatment to restore it, possibly giving him several scars.


Past Personality

Although he 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. Although magicians were viewed as heresy among mankind, even among them it had felt like he had become a completely different type of creature.
~ The author describing the corruption of Ike.

Concept of a young Westcott.

Despite all his cruelty, Westcott was showed to be a person like any other and was not evil from the start.

Westcott was once a kind boy who was known for being a charismatic boy who loved to talk with other people. At one point, Westcott was shown to be gentle enough to support the weak as seen when Ellen cried in front of him for being a failure as she could not use magic like him and other children from her age.

At that time, Westcott was an already a genius by nature and showed great skills for magic, alchemy and occultism, because of that he was very popular among other children and would teach them to be pure and respected mages without using extreme rules used by the adults to teach magic to other children. However, despite the adults from his village were rigid to all children, he could understand their situation as they were afraid of being discovered by normal humans. Westcott was shown to be also neutral over humans, and completely understand the fact of being feared by them as humans are afraid of things they cannot comprehend, and that fear would become madness to the point of paranoia.

Westcott feeling joy and pleasure in his suffering

However, due to his superior persona that was above from everyone's view of the world, Westcott began to grow bored of the world. When his pet died, he developed a twisted sense of ethic as he felt pleasure and joy in his own suffering. At the same time, Westcott developed a masoquist sense of perspective as he enjoyed every single moment of his sorrow when he saw his mother dying in front of him. When he discovered that death "shaked" his boring world, Westcott became obsessed with death as it brings all negative emotions of a living being. His obsession for losing something important was so "important" for him that he adopted a new dog just so he could wait and see it die again just like his previous one. 

Because Westcott was neutral over humans, the moment a group of anti-mages faction destroyed and exterminated his comrades, caused him to think humans were cruel and evil by nature as his race offered peace many times to other human societies. According to him, humans were barbarians and should be destroyed as he recognized them as dangerous to the planet and maybe from the whole universe. Westcott, however, developed an admiration for the cruelty of humans as he saw their actions as a "beautiful" way to inflict the same despair and pain he loves. When he was adopted by a British couple, his personality changed radically, becoming a person with a great ambition, his ambitions were so strong that it leads him to kill his own parents to have all their fortune for himself to speed up his plans.

Believing that if things were to go on, the world would eventually perish, Westcott eventually gave up on the idea of creating a world for the mages and decided to rewrite the current reality, a world without wars and conflict where mages will rule as the master race. He started to change his plans in creating a world for the mages and aimed to rewrite the human world instead. Unlike his friends who wanted to create another world where mages would live in peace, Westcott wanted to bring about the Apocalypse to kill all humans of the world and use the power of the Spirits to rewrite the human world according to his own views. In truth, Westcott was using the humans' cruelty as an excuse for the rest of his fellows to follow him in his quest for genocide, even knowing that what he was doing is basically the same.

Around the time he was adopted, he became even more arrogant and couldn't take criticism. In addition, he became even more rude to all humans around them, treating them like animals and disgusting pieces of trash. When Westcott and his friends created the Spirits, his mind got even more twisted and corrupted with the supernatural powers of the Spirits as he believed their powers are equal to a God. The moment he discovered their Sephirah Crystals, the very core of their immense powers, could be removed and transfer their powers to a normal person like himself, he lost completely his moral codes and views of life and death, becoming the ruthless psychopath he is nowadays and could only care for himself and his plans while treating everyone around him as pawns for his dream which he consider to be for the "greater good".

Current Personality

You should have renewed your thoughts from this matter. He is a monster. He is different from us. His thoughts, value system, and his authority to make that real... everything. We were the foolish ones for looking at a dream even if it was for an instant.
~ One of the DEM Directors to Roger Murdoch about Isaac Westcott.
Through his own nature, Westcott seemed to be death incarnate. He insistently made clear to Shido Itsuka and his enemies, however, that he did not believe himself to be evil, but simply beyond common morality. He was instinctively treacherous, betraying and killing numerous beings who trusted him as he showed no empathy for humans, a race that was under his command in DEM. Since his youth, Westcott was a natural genius and showed that he was patient, arrogant, vastly intelligent, and an incredible actor as he could manipulate the entire globe according to his desire.

Westcott is an intelligent man who often addresses most of his subordinates by their surnames (except Ellen Mira Mathers whom he called her name often in a teasing tone). He is also a man who does not speak too much. He rarely shows any sign of alarm, surprise, or anguish and is always shown smilling. In normal situations, Westcott is casual and uncaring, attempting to draw a conversation and make small talk, which often infuriates those he is talking primarily among the directors of the D.E.M that are part of the board of D.E.M except Ellen. Westcott is also a kind of person who does not like to repeat the same thing twice since he sees humans as inferior. Due to the power that he has over his officers and other employees on D.E.M Industries, he is very selfish and traitorous, as he doesn't care about anyone's life and even his own. Isaac Westcott brutally tortures his officers if they question his orders regardless of whether if they are elite soldiers or not; which is why Westcott often install Realizers in the brains of his soldiers in order to make them into "domesticated-psychopaths" so he doesn't need to worry with small rebel cells rising in DEM. Under normal circumstances, he becomes honest and thoughtful towards his subordinates (for beginners who do not know his true nature, people like Knox).

He is also very a twisted and callous man who seems to take pleasure in the worst possible types of torture, such when he considered various types of cruel physical, mental, emotional, and sexual tortures to Tohka that only the most twisted of individuals could think of. The definition of Westcott is a complete and utter obsession with death, sorrow, genocide, and greed with the powers of the Spirits' Inverse Form. By his own admission, he loves all kinds of war crimes that mankind can evoke over the world as he have a strange and bizarre fetish for despair and death, considering it to be the best emotion he can feel and inflict in other people (much like other Japanese villains like Junko Enoshima), he clearly shows that he hates any form of pacifism as he believes kindness will accomplish nothing and that sacrifices are necessary. This was later shown during Murdoch's events when he refused to kill Murdoch because he has a potential to become unfettered revolutionary; a magisterial dictator with strong ambitions. While he says "will be for humanity's greater good" humans will follow Westcott blindly because of his great authority and experience as a veteran, and all of them are able to kill thousands of innocent as long Isaac says this is correct. In a narrative sense, Isaac's unfettered and violent personality that is deeply inspired in revolutionary dictators of real life (Josef Stalin and Heinrich Himmler) serve as a counter to the easygoing, peaceful, and gentle personalities of Shido and Elliot that believes peace and equality is born from love and harmony and not power and oppression.

He also seems to have a one-sided view on many things as he claims Elliot Woodman betrayed a vow he made with him after he left the DEM. He even asked Elliot to come back to the D.E.M and saw Elliot's actions as a childish person throwing a temper tantrum. He frequently appears to play with his underlings for amusement such as playing rude and sarcastic jokes and at times he needs to use extreme and scary jokes to put fear in some members and soldiers of the D.E.M to keep them line as he needs his private army at all costs to fight Ratatoskr in a future war of large scale. Being the director D.E.M Industries, Westcott controls his minions through acquiring their respect by fear and holds the most rambunctious and turbulent individuals like Roger Murdoch in line through intimidation and mind games.

Isaac is also rather uncharitable, so he reacts violently to criticism. He tends to view most problems and situations in an extremely perspicacious manner, like an academic or a professor, rather than as a manner of life or death. Believing no force in the world could challenge his authority since he is the director of the greatest corporation on Earth, he typically underestimate his foes for being pacifists and that their kindness ends up generating in their defeat as he believes kindness will accomplish nothing but defeat. Ultimately, Isaac could also be viewed as yet another example of a Machiavellian inspired ruler, with ruthless determination to kill everyone on his way. But unlike Machiavellian who is a tyrannical ruler, Isaac is president of a company but he is seen more like an undemocratic dictator oppressing people in the shadows. And unlike tyrants who seek for more power—Isaac plans to seek more death on humans to get his vengeance of all mankind for bringing death to his people. Many of Isaac's beliefs run consistent with nihilism, as he does not see any meaning to life. He sees his actions as a game, even if said game results in the loss of lives, his very own included.

He often says things to incite someone's temper but then says he is just kidding. Isaac enjoys irritating Ellen Mathers to a troll level, and he has a great deal of fun in being feared by other officers as well. On the outside, Isaac acts empathetic and charming, however, he keeps many secrets and tells many lies to the whole planet. He is also very strategic and shrewd, so he enjoys manipulating battles in order to make his own allies and enemies kill themselves. He immensely enjoys crushing the hopes of humans and watching their expressions become filled with despair as see in Tohka's inversion experiment when Tohka and Shido's love failed. Despite all his cruelty, he insistently made clear to Ratatoskr, however, that he did not believe himself to be evil, but simply beyond common morality, calling evil "the humans who oppose him" as he believes himself to be the most righteous person in the world as he have a reason to exterminate mankind.

To those who had been at his nonexistent mercy, Westcott was known to be exceptionally sadistic, and he often took visible pleasure in torturing others. He was similarly quiet bloodthirsty as well, and frequently reveled in combat to the point of laughing while he fought or killed. He was also noted for his lack of forgiveness. At first, Westcott wanted to create a world without humans where mages will rule in peace but over the course of the years, Westcott began to take his desire for peace too far and decided he was the only one who should rule the world to guide it a new era. When he summoned the Spirits, Westcott decided to use the event to his advantage, by creating the belief that they are alien-monsters made to destroy mankind, in order to give the world an enemy to direct their hatred against. Using this threat, his company sold many weapons to all police forces and military of the world to rise against those "evil beings".

Westcott is also a deeply misanthropic man who tries to convince all nations that his evil deeds are justified because they are for greater good of the world, though he is an atrocious, cruel, prejudiced, sinister, vicious, and brutal businessman who uses his place in power to meet his own extreme ends, even employing mercenaries, terrorists, psychopaths and rapists like Minerva Liddell and Jessica Bailey to enforce his interpretation of Humanity's will while posing them as "soldiers." This makes him feared and reviled throughout the world as shown in Japan Ground Self Defense where the military officers showed fear towards him as he is one of the most important figures of the world. Westcott is especially determined to eliminate all humans scattered everywhere after using their resources, help and all support that all nations of the world used to rise him to power, showing that in the end, no matter how useful his human minions were, he will always abandon them to die simply because they are non-mages. However, despite being a highly dangerous and violent man, he thinks himself superior and even purer than most of the people as he sees himself as the "savior" of the world while considering all humans as "monsters". Westcott has shown to be haughty and self-assuming. He has also been shown to have somewhat of a god-complex, like for example, believing that he should "destroy the world and create a new one" if the current one does not operate in the way he wants it to.

Despite his single-mindedness, Westcott's true weakness was his arrogance that leads him to many defeats at the hands of Ratatoskr, Asgard Electronics, and the Spirits. His pride over his army and Wizards lead him to believe Ratatoskr was a group of "greenhorns" that could do nothing against him as they use peaceful methods to achieve their goals. Soon, when he thought he could simply invade their base with a small squad of Bandersnatch and Wizards and win, he got severely wounded by his old friend, Elliot Baldwin Woodman, for overestimate his soldiers. However, Westcott also states he fears Elliot as he was once a powerful Wizard. During their battle, Westcott mentioned he was shaking in fear when he was about to fight Elliot in a battle where Westcott loses one of his arms. After this incident, Westcott stopped overestimating his enemies and considered them all as threats to the point of moving all his army to defeat them.

At times Westcott can also be very childish. Both Ellen and Karen admit that his actions with his newly acquired Demon King resemble a mischievous kid playing with a new toy. Isaac also shows on screen that he is laughably evil at times when is played for laughs in his misfortunes with Ellen.

Official Description

- Elliot: Perhaps that may be right on the mark. Ike was always steadfast, though that might be why he's such a treacherous person. Think about it. What'd happen if he were to wait inside a room full of nuclear warheads buttom with only curiosity plaguing his exuberant mind?
- Karen: I couldn't imagine how dreadful that'd be. He's literally a psychopath.
~ Elliot Baldwin Woodman and Karen Nora Mathers about Westcott.

Sadistic and evil to the core, he is the twisted managing director of Deus.Ex.Machina Industries and is the possible reincarnation of the Antichrist in the series. He is around 30 years old and a tall man with dark ash blond hair and sharp eyes. He seems to know more than he lets on, such as the knowledge of Tohka's transformed state, as well as Shido's past. All of DEM's elite wizards refer to him with -sama, fanatically loyal, and willing to do terrible acts just because he said so. Considering Mana's amnesia before she joined DEM, headaches whenever she tries to remember the past, and respect for Westcott even after finding out what was done to her there is a possibility that brainwashing, conditioning, and/or a Realizer used to make them so loyal to him alone. Such as when Adeptus 3 was hesitant about a mission to capture Tohka that would expose their equipment to the public and create numerous civilian casualties just to slap Ratatoskr's face rather than use a plan to minimize both, such as the original plan on the island where the Yamai twins appeared. Yet she and the others were going ahead with it without reservation simply because Westcott said it would be for "humanities' greater good." Isaac himself has shown little care, much less humanity, in his thinking as long as his goals are realized. Whether it is discussing ways to break Tohka's spirit through torture with the same manner and care one would discuss the weather, or the loss of life and DEM property when Tohka snapped, he never showed any sign or thought of guilt, despair, sorrow or grief, but was happy that she inverted as if nothing else mattered.

Westcott grew up in a town of mages who could use sorcery along with Woodman and Ellen. However, civilians who feared the power of mages scorched their village. This event caused a change in Westcott. This became the first step to the creation of DEM. The trio spent their youths learning everything they could about sorcery, leading to the foundation in creating a Spirit, a being of immense power born from the mana of the world which they could use to achieve their goal. Around the same time, Westcott was adopted by a rich couple, but, ended up dying in an accident, leaving their entire fortune to Westcott. Afterward, he gained a desire to create a utopia, one with only mages living in it.

Other appearances

Ars Install

DEMArusu Installji

Isaac Westcott creates Marina Arusu.

On the game Ars Install, Westcott is the overarching antagonist manipulating all events behind the scenes. He is the man responsible for creating Marina Arusu, also know as Unknown, alongside with his assistant, Ellen Mira Mathers.

Marina Arusu was a sentient-virus (with self-consciousness) by Westcott to watch over Ratatoskr and hack the program of the Fraxinus. He was also nicknamed by Marina; In the Marina route, she called her creator as "Otoo-san", from the Japanese means "Daddy". Marina shows her loyalty to Isaac in the very end.

At the end of the game, it was discovered that Westcott manipulated his own daughter, driving her to death while he destroyed the Simulator Reality of the Fraxinus System. In the process Marina Arusu died since all she wanted was to be loved by Isaac Westcott but at the end of the game it was revealed she won nothing but contempt as he created her to be nothing but a computer program.

In the true ending, it is revealed that Marina performed good deeds before her demise after discovering her mistakes in believing in Westcott. She sent Maria's mail message to Shido's phone (in which Maria thought would be unreachable), and even installed Maria onto his phone.

Seha Vs. Dark Tohka


Westcott in Seha Vs Dark Tohka.

In the mini Korean-manga adaptation, Westcott appears as the hidden Bigger Bad, and the true main antagonist. He succeeded in awakening the Demon King in Tohka, however, in this adaptation, he created an artificial Spirit called Seha and forced him to fight to death with the Demon King.

While Seha and Dark Tohka were fighting, millions of people were killed in the process, and the entire city was completely destroyed. Westcott insanely laughed as he watched the fight between Seha and Dark Tohka. Even if the fight between two super-powerful Spirits were killing thousands and thousands of innocent, Westcott saw it only as a bonus for his own amusement. Even Ellen, who was next to him, was disgusted with his attitude.

Mayuri Judgment Film

Isaac is indirectly mentioned by Kotori in the film when she thought that "the Giant Ball of Mana" flying over Tenguu City was his work.

Powers and Abilities


  • Authority: It may not seem like a power, but his authority is one of his worst weapons. He has control about any kind of authority on Earth (being the only person in the world able to create Realizer). Westcott is considered one of the most important people in the world by the fact that he is the only person who can manufacture Realizers. With his authority he can do whatever he wants with any human on Earth, he can commit any evil act without punishment.
  • Magical-Technology: Isaac Westcott only creates magical technology, however, he never used it in a direct combat or in a fight. He uses it just in case he really needs to, during the transformation of Dark Tohka he used magic to teleport to somewhere.
  • Gifted Orator: The main asset of Westcott is his ability to inspire his troops with enthusiastic speeches. It can take almost any situation and turn it into a speech that will strengthen the morale of his soldiers and Wizards for their next operation or mission.
  • DEM Wizards: Wizards are trained (or brainwashed) to be psychopaths who loyally obey him, so they would give their life because he ordered. His wizards are fanatical soldiers and almost soulless.
  • Fear and Torture: These "weapons" are used by Isaac almost in everything he does or says. Also one of his fetishes. Most of his soldiers had been formed on the basis of the fear, as seen in episode 4 of the season 2, when James was showing fear in returning to D.E.M with empty hands. Westcott tortures his soldiers in the cruelest ways possible for their failures, such as psychological torture, depriving them of oxygen and/or rape.

Inverse Spirit

12140044 52623350494198484 877620069610233400 o

Nia's Angel, Rasiel.

When Nia Honjou went into her Inverse Form, Artemisia Ashcroft was able to extract her Qlipha Crystal (inverse Spirit form's crystal) from her body and gave it to Isaac Wescott. He then bonded with it in his chest, giving him all the powers of Nia's Inverse Form (at least half of them thanks to her near-inversion state).

One of the powers he gained is an ability to summon Nia's Demon King, Beelzebub, a book with basically the same powers as Nia's Angel, Rasiel. The book can give a person information about a subject just by thinking about it, as shown when Westcott found out about Shidou changing the past during Tobiichi Devil events and can alter the future, through only for a few seconds max. However, unlike Rasiel, it has also shown to have the ability to summon shadow-like creatures from its pages. However, Nia's Inverse Form was in incomplete form because of Shido's intervention.

  • Demon King: Beelzebub; "Tome of Divine Corruption" It can transfer information about a subject directly into his mind if he just thinks about it, as shown when Westcott found out about Shido changing the past during the events of Tobiichi Devil, and he can freely share this information with others just by simply touching them. It can also summon shadow-like creatures from its pages that follow his every command.

DAL v17 Index

Nilbecol, soldiers of Westcott's personal army (expy of Marina Arusu).

However, since Nia's Inverse Form was in an incomplete state, because of Shido's intervention, only a part of her Qlipha Crystal was extracted. As a result, Westcott's Beelzebub is also in an incomplete state, implying that the Demon King is not as powerful as it was, and/or does not have all the powers it had when Nia was using it. Beelzebub still has a connection to Nia's angel Rasiel, as the two used to be two sides of the same embodiment. As a result, Nia can sabotage Beelzebub by interfering with its information network, which she has used to further weaken the Demon King. Also, Nia states that, like Raisel, Beelzebub is incapable of predicting the future or reading a person's inner thoughts.

So far the Demon King owned by Westcott, Beelzebub, has shown to have the following ability:

  • Ashufiriya: Traps the target(s) into the book and transports them into an adjacent world created by Beelzebub. According to Nia, the world is created by various scenarios made by people's dreams and imagination. The people imprisoned assume the roles of fairy tale and manga characters, though several alterations might be made to the source material. While trapped within the fantasy world, other Spirits are unable to use their Angels.
  • Nibelcol or Daughters of the Demon King: Summons various soldiers from Beelzebub's pages, all of whom bare a striking resemblance to Marina Arusu. However, due to Beelzebub's connection with Rasiel, the Nibelcol has a significant weakness despite their great numbers. Because Shido still has Nia's affections, he is able to seal the Nibelcol with a kiss, causing them to revert back into paper and fade away into light particles.


Part 1

It is an honor to meet you, Princess. No… Yatogami Tohka, right? I am Isaac Westcott from D.E.M Industries. I'll be in your I being hated? [...] My! Yes. That would actually be very simple. I want your powers as Spirit to turn the ways of the world upside down....In order to topple the restraints of this world. But you existence in this world is stable. I wonder what I have to do to make you despair? [...] To hate this world, to hate humans. Even the strongest Angel isn't capable of filling the hole in your heart. You can only rely on external assistance beyond that of an Angel. How is it possible for you to enter that state? Looking through the AST records, there was a time when you was indeed near such a stage...what exactly happen then? [...] *sigh* --I say, Ellen. Maybe it would be faster if we increased the physical torture on her? Let's start off with electrocution. And then decrease the oxygen concentration in the room, and observe her reaction. Maybe we can also try changing the air pressure. If those fail, then let's chip her nails away, and her fingers… ah, right, maybe we can chip her teeth too. The pain felt by the nervous system will be unbearable by then. A Spirit's body is much more resilient than a human… try feeding her poison. Ah, in that case, we should also give her tranquilizers. And then, yes, you're a virgin? How do you feel about your own chastity? The pain you will feel when we completely destroy whatever "dignity you have as a woman". In the long time you've spent in this world, have you had any friends or lovers? If we were to kill a loved one in front of you, how would you feel?
~ I am Isaac Westcott introducing himself to Yatogami Tohka.
Ellen, with this I am certain. A peace-loving idiot is much scarier than anyone with dementia.
~ Isaac Westcott
Kuku, I wonder why, I am a little happy. Those greenhorns, to think they outwitted me.
~ Isaac Westcott
Incredible. This is the first time I've seen such a perfect Reversal. –Look at this, Ellen and Tohka. That is the fruition of our goal! Our dream! Alright, it's time to work. Finally, the enemy for you to defeat has appeared. Go, my strongest Wizard. Now is the time to dethrone the tyrannical queen, and become a stepping stone to our greater heights.
~ Isaac Westcott
I have expectations for you, young Wizard. If it is you, you will definitely shoot down the Spirits. If you have anything that is troubling you, you can call us anytime you like. DEUS.EX.MACHINA, will not spare any efforts in helping your cause.
~ Isaac Westcott
Do you still not understand, even though I am saying this much?
~ Isaac Westcott
The Demon King we have not stopped yearning appeared so easily, I wonder who on earth has imagined that. The Spirit at the very least Princess, values, trusts and loves him to the depths of her heart. Isn't this wonderful? They will probably deepen their trusts even more. For the time that will come………….neh.
~ Isaac Westcott
Hahahahahahaha! Hahahahahahahahahahahaha! Kuku, a boy that is able to use the Spirit's power .I've heard about this and thought it was impossible but, I see, so that's how it is. Kuku, haha-hahahahahahahahaha! Isn't this funny! In the end everything was on the palm of her hands huh. Hahahahahahaha!!!
~ Isaac Westcott
Did you see that, Ellen? Everyone there did not see how grave that matter was. All of the incompetent fools joined together, were weird enough to put the blame on a genius that is 1 in 10,000.
~ Isaac Westcott to Ellen Mira Mathers.
I'll leave this matter to you Ellen. Ellen Mira Mathers. The strongest Wizard that is second to none. If it is you, you'll definitely be able to accomplish it. No matter whom the opponent is, even if it is the being that causes the atrocity of destroying the world.
~ Isaac Westcott to Ellen Mira Mathers.
Not really, if that is the case then I don't mind. I prefer humans filled with ambitions enough to bite off my neck when they get a chance.
~ Isaac Westcott
That was a letdown. Even when 30 years passed, it looks like the fever that harmed you has not completely healed......then, I won't go easy on you the next time we meet. I will use the Spirits for my dearest realization.
~ Isaac Westcott
This is my first meeting with you. My name is Isaac Westcott from DEM Industries.
~ Isaac Westcott, president of DEM Industries.
Let us meet again, if you survive. Takamiya.... I mean, Shido Itsuka.
~ Isaac Westcott
I see. You can think of it that way too. But this is troubling. A subordinate that listens to me and a subordinate that works for my sake, I wonder which one is better.
~ Isaac Westcott
The Kingdom has inverted! Now, prepare yourselves, mankind! It's time for the triumphant return of the Demon King!
~ Sir Isaac Ray Peram Westcott
Don't praise me like that. I'll feel embarrassed.
~ Isaac Westcott
Rest assured, after I finish my fun and self-satisfaction, I will give this company to all of you. Oh, it's going to be soon. Compared to the team we continuously waited until now.
~ Isaac Westcott
It's simple. Compare to dropping a glass, dropping it from a higher place make it broke much easier.
~ Isaac Westcott
It's better to enjoy the fun one at a time.
~ Isaac Westcott
Human emotions is just a highly evolved form of logic.
~ Isaac Westcott

Part 2

Yes. Are you saying that my decision is mistaken?
~ Isaac Westcott
I expect a lot from you, Ellen. But for a long time, you wouldn't want to avoid getting yourself bathed in blood from head to toe.
~ Isaac Westcott to Ellen Mira Mathers.
Now, within a fairy tale… struggling in fantasy.
~ Isaac Westcott
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 as a child.
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?
~ Isaac Westcott after witnessing human nature.
Ah. The Spirit will be born── in the wake of a new world enveloping this world. ──Voluntary territory. A universal space that should only exist in humanity's imagination is being changed into reality. If the calculations are correct, the space of the Spirit being born is to the extent of covering the entire earth. The scale is enough to be called another world──the neighboring world. That is our world. We will overwrite our world with the neighboring world.
~ Isaac Westcott explaining his plans to his friends.
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.
~ Isaac's message to Kurumi Tokisaki.
You've finally appeared──Deus. My dearest, Spirit.
~ Westcott witnessing Mio Takamiya
Now then, Itsuka Shidou. Let’s decide here. ──Decide who is more qualified for the power of the Spirits.
~ Westcott announcing his final battle with Shido
Because of Deus' Angel, even my flagship has been destroyed. My crew didn't make it. No, no, thinking over it again, it truly is──such a wonderful power.
~ Westcott showing his lack of empathy for his men
My purpose? It’s for the sake of creating a new world... Ah Maybe you have already heard this from Elliot, but we are decedents from genuine Mages unlike those artificial magicians (Wizard). At one time, by the hands of humans afraid of our power, our hometown was burned down and compatriots killed. So I will rewrite this world with the neighboring world of Deus. In order to have revenge on the human race that killed our family.
~ Westcott explaining his goals to Shido
According to one theory, the first two types of emotions people experience can be distinguished between pleasant and unpleasant. Through growth, human emotions become differentiated into all sort of different feelings……but no matter what, every emotion basically can be characterized as pleasant or unpleasant, people favor pleasure and dislike discomfort. Actually, the reasoning behind that is not an exaggeration. For instance, people who derive pleasure for social status tend to place more effort in work. Or people who regarded it pleasant to be loved by others tend to give more soothing offerings. My position is only slightly different from others. Nothing more, nothing less. There’s nothing changed after that. I am making as much effort as possible for the sake of my curiosity and goals. ──Itsuka Shidou. Have you ever spent money looking for a toy? Have you ever tidy up your appearance before searching for love? It’s no different from that. ──In that sense, I am a very ordinary person.
~ Westcott trying to convince Shido he is not the bad guy
Indeed you are certainly the natural enemy of the Nibelcol. However, I don’t think that it will be decided by just that. You seemed to have thought you have won in the previous battle, but that folly is the equivalent as laughing at a concert without its conductor.
~ Westcott facing Shido
Wow. Diva and Witch. How delightful. In addition to Itsuka Shidou’s reiryoku, I’ll be able to obtain two Sephira Crystals in completion!
~ Westcott convinced he is going to win

Last Words (dialogue)

Third Timeline (killed by Mio Takamiya)

  • - Isaac: It appears I’ve lost. So this is the endpoint. Hmm.... how unexpectedly boring.
    • ".........."
    • - Shido: Yes, I do want to kill him. In fact, from the last blow, I thought to myself it couldn’t be helped if he dies while firing. You're going to live, Westcott.
    • - Isaac: Is that okay? I don’t think there will be a second chance. Takamiya... Just kill me and end this.
    • - Shido: How noisy, the loser shouldn’t make irresponsible remarks. You wil pay for everything you did in this plane of existence.
    • - Isaac: Haha, the way you talk is similar to Elliot... unfortunately, I was quite interested in the feeling of death... ARHH!!

Fourth Timeline

Westcott's Introductions

Throughout history, Westcott has always received numerous introductions when he firstly appeared in a Volume or part. Many (if not all) of them explain the sinister nature of Isaac Westcott.

Volume 5

  • 1st Appearance - "Seeing the face of discomfort and his puzzled voice, Origami turned behind and took a glance. Over there, a man was standing, accompanied by a girl who appeared to be a secretary. He was a tall man wearing a jet black suit. His hair was dark ash blond, and he had a pair of sharp eyes as if a knife was used to cut a slit on his face. His age should around 30 years old, yet, he was a mysterious man that gave off a feeling that of being an experienced veteran. Seeing that man's face, and hearing Kiritani saying that person's name, Origami moved her eyebrows a little."

Volume 6 & 7

  • 2nd Appearance - "In the suite room of the top floor in the Imperial hotel located at the west side of Tenguu city, Isaac Westcott sat down while sighing. He raised his chin while slightly flicking the tip of his dark ash blonde hair, and further narrowed his eyes which looked like sharpened blades."
  • 3rd Appearance - "Of course, Jessica wasn't someone who kills for pleasure. It was not like she does not feel any sympathy toward the considerable number of casualties that will appear from her own attacks. But, that slight sentimental feeling was completely erased by the sweet sound of Westcott's orders which imply capturing the spirits is for the greater good. Right now, Jessica only recognizes the stage audience as a group of potatoes or pumpkins."
  • 4th Appearance - "A few seconds later, the wall cracked as before, and a door opened. And from there entered a man. He was a tall, thin man. His most striking feature was his silver hair and sharp eyes that looked like they were carved into his face with a dagger. Closely between the ages of 35, a dangerous, dark and evil aura around him, masking his true age. When the man entered the room, Tohka felt a strange feeling of unease. It was not because Ellen had spread her Territory. But for some unknown reason, the moment Tohka saw that man, she felt as if the temperature dropped several degrees."

Volume 8

  • 5th Appearance - "All of them were board members of this DEM Company. Everyone was sitting at a giant elliptical table and were flipping through the documents on their hands while making the same difficult face. Nonetheless, it was also something not impossible. Everyone one of them should have already received reports from here and there. And even the documents on their hands had the situation written in details. Nonetheless naturally, it's not like everyone who was there was making that face. On the chair placed the furthest back of the room. Over there one man sitting calmly. He had a jet-black suit covering his body. A young man around the age of his mid-thirties. As if looking over the meeting, his unpleasant eyes that expressed darkness were peeking from the gap of his dark grey bangs. Sir Isaac Ray Peram Westcott. He was the DEM company's which was exactly the topic of discussion right now."

Volume 9

  • 6th Appearance - "Having finished the remaining simple business inside the private jet, Isaac Westcott came out from the VIP entrance of the airport and rode the car waiting for him before heading towards the lodging area in Japan's Tokyo metropolitan Tenguu city's hotel. He was a characteristic tall man with dark ash blonde hair and a pair of sharp eyes like naked blades. His age should be around in his mid-30 but, the dangerous atmosphere covering his body was disrupting the appropriateness of his age. At the least, he was somewhat too young to be burdened with a world class enterprise known as DEM industry---------such an impression was probably impossible to someone unless they have met with him directly."

Volume 10

  • 7th Appearance - "It was a young man around his mid-thirties. He has dark ash blonde hair and bladesharp eyes. His eyes filled with darkness could make the people facing him feel an indescribable anxiety. Sir Isaac Rey Peram Westcott. He was the managing director of the huge world famous company, DEM industries."

Volume 13

  • 8th Appearance - "The man is being assisted by an ash blonde haired woman whose appearance could attract every man. Her facial expression is as sharp as a sword which would cut them down, making those two fall into silence with their faces getting paler. That man's appearance looks young. It seems like he's in the middle of thirties. But why does this young appearance suit with him despite his age? He doesn't looks like a middle age man at all. Actually, this year Knox is 48 years old, so you can say that this man's age is younger than him. Of course that's only natural. The person over there isn't an ordinary man. He's a man whose name is famous in the world as a world genius financial monster from DEM Industry, its first generation founder: Sir Isaac Westcott."
  • 9th Appearance - "Suddenly, Shidou could sense something dangerous and turned his glance to a certain direction. Perhaps it was because his senses were sharpened from using a Spirit's Reiryoku. Or else, it's all because the presence of that person over there is way too bizarre to the point that he couldn't ignore it. Though he wasn't sure what it is--------But there's a [Foreign] existence that slipped in between them who wasn't here until just now. He knew and felt that person's presences clearly. It's not only Shidou; all Spirits who were present there also pointed their gazed towards the same direction. While being looked by everyone, that man was walking slowly towards Artemisia and Nia. He was a man with ash-blonde hair and wearing a black suit. Shidou looked at that man with a surprised gaze. Isaac Ray Peram Westcott."
  • 10th Appearance - "At the moment, Shidou felt that the Spirits choking at the same time. The malice that he felt since the first time they previously faced Westcott began to expand. This man can't be described as cruel or brutal. He can only be defined as ------ [Abnormal]."

Volume 14

  • 11th Appearance - "Peering inside, they could see a man sitting on a chair in the room. He had an impaling pair of eyes under a dark ashen hairline - alongside a floating pitch-black book at hand. He was the renowned ruler of this company - Isaac Ray Pelham Westcott, in person."
  • 12th Appearance - "Westcott intently stared at the pitiful wizard, like a predator hunting its prey. The unfortunate girl's facial expression instantly paled, and she hurriedly shook her head insubordination."
  • 13th Appearance - "Lingering amidst the white smoke was a man wearing black Western-style clothes and a wizard equipped with a CR-unit. The two leisurely walked out of the mist."

Volume 16

  • 14th Appearance - "Ellen came to an abrupt standstill, having detected that beyond the door lingered an unwanted presence. Despite Westcott possessing an air of intimidation that the majority of commoners nowhere near did, the roiling presence a meager doorstep away distilled a unique ambiance. As if——yes, as if a horde of horrors awaited them both with hushed breaths."
  • 15th Appearance - "The moment Ellen got up, the door flew open as a man came into the room. The man gave the impression that all of the world's darkness had compacted itself into a human shape. He has dusky ash colored hair and a pair of eyes resembling metallic rust. Although he looked about thirty years old, the oozing sense of intimidation and dread he was emitted wouldn't match that assumption. Sir Isaac Ray Pelham Westcott, the king of magicians who had established DEM within a single generation."

Volume 17

  • 16th Appearance - "And from the very back of the group──a very prominent man came to the forefront. It was a tall man who was about 20 years old. He was characterized by dim silver hair and rusty eyes. Although his expression and behavior were very gentle, his body was emitting the strange atmosphere that he couldn't completely hide."

Volume 18

  • 17th Appearance - "As if to confirm his premonition, a man came out from the shadow of the rubble. Dim ash-gray hair and eyes with a dull metallic hue, there was a strange threatening atmosphere coming from him that was different from confronting a Spirit or Wizard. Yes, he was the executive director of DEM industries and the starting point for this battle. The first man that started the conflict over the Spirits."
  • 18th Appearance - "The sweat dripping down his cheeks reached his lips, causing a salty taste to spread in his mouth. Shidou didn’t dare to loosen his guard as the eyeballs in his eye sockets orbited around to scrutinize the nearby surroundings. There was an innumerable amount of Nibelcol paper in their vicinity. And at the very end──a man who personified darkness quietly stood there. Sir Isaac Ray Pelham Westcott. The head of DEM industries and the enemy of Ratatoskr, And also──the man who brought Spirit into this world 30 years ago alongside Elliot and Ellen, providing the impetus for the current battle. No──not only that. Shidou glared at Westcott with a glare brimming with animosity. For Shidou who had regained the memory of “Shin” now, this man was the subject for the clear hatred of killing him and kidnapping Mana."


  • The recents volumes from story revelead much about Westcott's psychological health. Westcott suffers from a twisted and serious psychological problem called Emotional Masoquism. Emotional masochism is basically when he find pleasure in engaging in emotional negativity and being miserable. In fact, Westcott is an emotional masochist who not only enjoys misery, but seek it out. Westcott loves to lose his battles so he can suffer humilliation of defeat, he seeks to lose someone he loves dearly by watching them die due to an accident or in a tragic incident and goes as far to witness the genocide of his own race to find the ultimate flavor of despair. This also follows him until his army, as he seems to like watching his forces being beaten and defeated.
    • Aside from his emotional masoquism, Westcott also seems to enjoy physical pain as well. His battles with the heroes during the story proves he also embrace the pain caused by his battle to the point that he let his enemies hit him with their attacks while laughing insanely. While others could consider it as a sexual pelasure, it's more correct to say that Westcott feels the joy of a kid having fun, which explains much about his childish personality.
      • His childish personality as a adult also open doors to new psychological problems like Bipolar Personality Disorder. As stated in the novels, Westcott was a genius and a prodigy, so he was always more "calm" and "composed" than the rest of the children in his village. Yet, no matter what, Westcott was a child even as an adult, and due to his genius nature that put him alone on the top of the hierarchy, Westcott never had real fun like he wanted, so he was forced to live an environment against his will. It was also said his parents were extremely rigid since he was the most important kid of his village, and was tested by the adults for most of his childhood. His BPD problem probably came with with abnormalities in his brain. Many studies about BPD have reported findings of reductions in regions of the brain involved in the regulation of stress responses and emotion, and the constant forced life he had live influenced in his mental maturity.
  • His name 'Isaac' means "He who/will laughs" in the Hebrew Bible.
  • Westcott's eyes are seem and described as lifeless and dull eyes. This, despite being a small factor about his character, is actually extremely important. The author himself made his eyes like that to show how his mind was plunged into darkness, disgrace and misery. People who loves living in sorrow consider living as the same as being dead, and Westcott's lifeless eyes show pretty much how dead he is inside... And how much he seems to accept it.
  • Isaac is a given name derived from Judaism and a given name among Jewish, Christian, and Muslim societies, generally in reference to the above. "Isaac" is loosely translated as "laughing". "Ike" and "Ise" are also short forms of the name Isaac.
    • Westcottef

      William Wynn Westcott

      From the Hebrew name meaning "he will laugh, he will rejoice", derived from meaning "to laugh". The Old Testament explains this meaning, by recounting that Abraham laughed when God told him that his aged wife Sarah would become pregnant with Isaac. When Isaac was a boy, God tested Abraham's faith by ordering him to sacrifice his son, though an angel prevented the act at the last moment. Isaac went on to become the father of Esau and Jacob with his wife Rebecca.
  • Isaac Westcott, Ellen Mathers and Elliot Woodman are based on the three co-founder of the Hermetic Order of the Golden Dawn, which was one of the orders of the Hermetic Qabalah. The Hermetic Qabalah was one of 3 groups associated to the Sephirot Tree.
    • Isaac Westcott is based on William Wynn Westcott, one of the three founders of the Hermetic Order of the Golden Dawn.
    • Ellen Mathers's last name likely comes from MacGregor Mathers, this may be why Ellen is the only Wizard who has been able to fight evenly with a Spirit.
    • Elliot Woodman's last name comes from William Robert Woodman, one of three co-founders of the Hermetic Order of the Golden Dawn.
  • Isaac Westcott is considered one of the darkest villain already created by Koushi Tachibana in his light novels. He also is considered the darkest villain among all villains and antagonists from Date A Live and Soukyuu no Karma. In addition, Westcott is the only villain originated from Light Novels that has the longest arc know (from volume 5 to volume 18--). Most of LN antagonists tend to appear in only one or three arcs to introduce worse threats in the future. The Greater Scope Villains usually appear only in the final volumes of the story.
  • Due to his long arc and countless acts of crimes against humanity and all life in general, Westcott is considered one (if not the) of the most evil villains to ever date in Japanese's Light Novel media. However, due to the high popularity of female characters in the story (a popularity that exploded in Asia), he is considered to be an overrated antagonist who didn't get the love he deserved. 
  • S2 16 Kasper 2

    Kasper Hekmatyar

    Westcott holds a great hatred for Ratatoskr, considering it an organization of "greenhorns" and its goal "something that can only be said out randomly while drinking a cup of sake".
  • Although not officially confirmed, Isaac was possibly based on the appearance of Kasper Hekmatyar from Jormungand.
  • Although not confirmed, it is possible that the ban of Date A Live II in mainland China (while the season one wasn't banned at all) was due to Isaac's darkness that gave too many disturbing scenes to the series. In addition, many of Westcott's tortures were used by the Imperial Army of the Empire of Japan during World War II and Sino-Japanese War. Those methods of torture were mainly used against Korean and Chinese civilians to put fear in the hearts of innocents.
    • One example of those were the brutal and inhuman tortures used on women who were raped, forcibly impregnated, then dissected alive by the Japanese Army and scientists of the empire. And during Nia's inversion Arc, Westcott willingly explained how he physically, sexually and psychologically tortured and dissected Nia alive for 5 years. 
  • Westcott was the first foreign character to appear in the franchise. After him, comes Ellen Mathers, Jessica Bailey, Simpson, Roger Murdoch, Russell, Charlotte Meyers, Daisy, Izabell, Minerva Liddell, Ashley Sinclair, Leonora Sears, Artemisia Bell Ashcroft, Edgar F. Caroll; all of them are British villains.
  • 649302

    Fugil Arcadia

    Fugil Arcadia, one of the main antagonists in 2013 light novel series, Undefeated Bahamut Chronicle, is heavily implied to be inspired in Isaac Westcott—based on appearance, personality, and crimes. Fugil is considered as the teenage version of Westcott. Despite being a teenager, he is the most twisted of all villains, this is demonstrated when he was willing to kill thousands of children and women to his brother to overthrow the Empire.
  • Isaac is the second white-haired character to appear in the franchise. The first is Reine Murasame.
  • He is the character of the franchise with the highest number of nicknames.
    • His fourth name can also be called "Peram", "Perham" or "Pelham."
    • His nickname "Ike" can also be called "Iac" or "Aki"
  • Isaac is self-proclaimed "Genius".
  • Isaac makes certain similarities with the Antichrist in Christianity religion, not because they are presented as monsters or being an archenemy of God, but for the very similar manner in stocks. Both are two beings who were born to bring destruction to the world and also are presented as people who have extreme political and military power in their hands, making both villains very dangerous and not so easy to beat. In some forms of fiction, the Anti-Christ is actually a person who suffered too much in his or her childhood, and their tragedy lead to them commit atrocities against the world they live; Westcott belongs to this side of Anti-Christ category.
  • His appearance looks very similar to all Abyssal in Kantai Collection. The pale skin, white hair, tall, thin body and lifeless eyes. This kind of appearance in Kantai Collection (or for the most to Japanese media) refers to soulless or undead beings.
  • Westcott seems to know more about the Spirits than anyone else.
  • Westcott was born with the name "Ike", but soon after he was adopted by a new family, his name was renamed to "Isaac Ray Peram Westcott".
  • It's heavily implied Westcott killed his adoptive parents as the Light Novel says that took not so long for his parents to die in an accident soon after he was adopted.
  • After the release of Volume 17, it was revealed Westcott was just like the main protagonist of the series, Shido Itsuka, who is a kind-hearted and a Pure of Heart by all means, however, he felt that the pleasure of suffering was more exciting as it shook his boring world where he was superior to everything. During his flashback, Westcott was shown to care for his comrades and friends to the point of breaking the laws of magicians to teach Ellen magic as he felt sorry for her. Unlike Elliot, who was teaching Ellen for pure review lesson, Westcott was teaching her for pure kindness.
    • Another curious fact about Elliot and Westcott is that they were the complete polar opposite. Elliot was more childish at the time while Westcott was a genius by nature and was even more mature and composed than him. Ironically, 30 years later, the roles changed as Elliot is now a mature, calm and kind man while Westcott is a childish, arrogant and cruel man.
  • ISAC and Dem hello image Ssm 8740

    ISAC and Dem

    While this isn't officially confirmed yet, Isaac Westcott and his company (DEM) are the possible inspiration for the creation of the webcomic ISAC and DEM.
  • It was theorized Westcott has more than a relationship between servant and boss with Ellen. James A. Paddington mentioned that others DEM officers claimed Westcott might be sleeping with Ellen. This probably came from his genius-like nature and her extreme beauty.
  • Westcott was shown to be very playful with Ellen, often making jokes and playing with her. The reason behind this is because he loves to see Ellen angry because he claims she is cute.
  • Isaac is one of the few characters in DAL that has a theme song with his name on the title.
  • Westcott is the character who has the highest body count on the franchise, even more than Kurumi Tokisaki who had killed 10,000 people with her own hands. It's implied his body count is around 200,000,000-250,000,000 since 30 years ago when he summoned the First Spirit and destroyed a large part of China and Eurasia. The following spacequakes around the globe may have increased his body count by the millions.
  • Westcott is often seen as a Bishonen character, even more than Shido Itsuka.
  • In Volume 17, Westcott is shown to be more understandable towards humans when he was a child but at some point he mentions their teacher's generation, the persecution of magicians was particularly violent. This can explain why he doubted humans so much.
