Mistleteinn is no ordinary Dream Demon. I was once a part of a group pursuing Mistleteinn. She was indiscriminately slaughtering Dream Demons in the Dream World. On that day, my allies and I caught up with her. We didn't stand a chance. I don't know why I was left alive. Was it just a chance? Was it on whim? Mistleteinn was spawned from the deepest pits of hell.....The pits of hell...Humans dispose of the negative emotions they accumulate during a day in their daydreams. They move on to happier days. The pits of hell are where all that supposedly dissipated spite accumulates.
~ Lestion about Mistleteinn

Mistleteinn is a malevolent and vicious dream demon who appears as an anime-exclusive villain in the animated adaption of Dream Eater Merry (or Yumekui Meri in Japanese version). She has the power to force dream demons into human vessels, later targeting and killing them, resulting in the vessel losing all ambition in their goals. She is extremely strong, as it is noted that she is acknowledged by Pharos Hercules for her power.

She was voiced by Sayuri Yahagi in Japanese version and Monica Rial in English version. The latter is known for lending a voice to some villains such as Rize Kamishiro,Dante (FMA 2003) in her Lyra form,Sayara Yamanobe and Umihebi


She has snow-white hair with a red crown of vines, blue-green eyes with an pupil in the shape of a vine with leaves. She wears a dress that appears to be made of plants, red and black colored. She has two vines at her back, that she used to trap and stab her opponents.


Mistleteinn: It looks like you’re enjoying yourself. What can you see from those depths?
Ijima: [Seeing Mistleteinn's reflection in the water] I can see the face of your cruelty. And the soul in which it grows.
'Mistleteinn: That goes for you, too. This is the first time I’ve had a vessel so similar to myself. You taught me a thrilling pastime. Sow seeds without water, and flowers won’t blossom.
Ijima: Harvest them.

Mistleteinn: If I hadn’t meet you, I would’ve just killed them.
Ijima: Your victims’ wishes should ripen to their fullest. Whether you let them came true or not is another matter. [Proceeds to tore down the sleeve of Mistleteinn's shirt]....Kawanami, Tachibana....all the pieces are in place. All that’s left...

~ Mistleteinn and her Vessel, Ijima, sharing a love for their sadism.

Despite having the outward appearance of a sweet little girl, Mistleteinn is vicious, monstrous, sadistic, and intelligent. She is playful in the sense that she enjoys toying with her victims almost as if she was purposely proving that she is a lot stronger and better than her victims before killing them.

Mistleteinn appears to be sustained by killing other dream demons as she hopes that their deaths will fill her stomach. In light of this she does not feel guilt upon destroying a child's dreams and ambitions, in fact her facial expressions and outbursts indicate that she is aware of what she is doing and enjoys it, further highlighting her sadistic tendencies. In spite of displayed savagery, she have a cowardly side as she willing to use dirty tricks for to make her enemies not attack her (as seen in the final episode when she swallowed Pallette and used her as a hostage in order to make Merry and Engi not attack her).

Mistleteinn does form a bit of a relationship with the equally sadistic Ryota Ijima. But the relationship that they have are only limited on praising how sadistic both of them. Other than that, she rarely interacts with Ryota that much and only Ryota shows a bit of a care towards her when she got shot by Chizuru and Lestion.


Mistleteinn is a dream demon who was born in the land of nightmares, and loved to kill dream demons more then anything. This was evidenced in Lestion's flashback where she murders most of Lestion's companions and then said that it was no fun that she slaughters all of them. When she arrived in the real-world, she met Ijima, who wished to crush peoples dreams and goals. He then became her vessel and the two became compatible. Ijima conjured up a twisted plan with Mistleteinn about forcing dream demons into his students when his students told what they wanted to do with her life. Mistleteinn then happily executes Ijima's twisted orders so that she could destroy the dream demons and turn his students dreams into nothing but ashes.

When Mistleteinn  forced Parade into Isana, sometime later she forced them both into her day-dream. At first she tried to get Parade out of hiding by imprisoning a confused Isana into a globe of water, hoping that by nearly drowning her, Parade would come out to save her however he still did not come out. She then, growing bored of waiting, released Isana, who fell into unconsciousness, and went to look for Parade. Her attempt was stopped when Merry and Yumeji entered her day-dream. Mistleteinn taunted Merry, such as wearing her hat and asking cruelly if her head really was as big as her hat. After this, she then proceeds to beat Merry and was about to destroy Parade by wrapping him up in chains, near Isana's heart, and is about to pierce both of them so that she could make a human skewer. When Chizuru stepped in and tries to stop Mistleteinn, She then says that she would protect Isana and her dreams no matter what. Mistleteinn then grew bored and said she'd let them go until next time with the promise to kill everyone of them.

In the next and final battle, everyone entered Engi's day-dream as their battle ground. She mocked Engi about her garden and then changes the landscsape to suits her own image, and also dodged every attack Engi threw before peircing her in her hip-area with a large thorn she had killed many dream demons with, leaving Engi unable to battle. Lestion then sacrificed himself to make the final bullet for his gun to kill Mistleteinn where Chizuru fired it, leaving her empty of dreams and everything in her heart. However though it was direct hit, she still did not die, and mocked the emotionless and empty Chizuru about the bullet that did not bear the promised fruit. Because of this, Merry tried to fight Mystlateinn but her attempt was stopped when Mistleteinn trapped Merry in an white rose-bud called The bud of Despair hoping Merry would be destroyed by her own sorrow the bud would force her to remember.

Yumeji then started to try and fight her with John Doe's Guiltion-like saw. And despite being mortally injured by Mistleteinn, he still kept fighting, planting a bit of fear into her, wondering what made him so strong. This is where Mistleteinn was proved to be a very, very weak dream-demon because the strength in the dream world isn't in ones body but their heart. Merry, who remembered Yumeji's words of bring her back home, destroyed The bud of Despair that imprisoned her and was now ready to fight with Engi who is now fully recovered from the strength of her heart.

In the last ditch effort to beat the two dream-demons, Mistleteinn swallowed Parade and taunts the two of what they were going to do now that her friend's dreams were in her belly. Merry however, with newly found confidence from Yumeji, slammed her hand onto Mistleteinn's chest, where half of her body disintegrated right were Leon's bullet had hit, proving his and Chizuru's sacrifice was not in vain. Parade then jumped out from her torn stomach, resulting in an immense amount of pain for Mystletainn. He jumped into Merry's arms and thanked her for saving him before she sent him back to the dream word.

Mistleteinn now damaged, was afraid and asked Merry who was she and how she could easily beat Mistleteinn herself. Merry responded to her that she was the dream-demon that swallowed up nasty nightmares like her before punching her harshly in her right cheek and saying that she was Dream Eater Merry. Mistleteinn only had seconds to see Engi coming to her, before she was sliced in half by Engi's sword disappearing in red vines leaves.

Powers and Abilities

Unlike other dream demons, Mistleteinn has been described, by Lestion, as being formed by negative emotions, such as hate and spite, in the deepest pits of hell. As such her strength far exceeds the normal dream demons Merry or Engi have encountered before.

Mistleteinn, in her own day-dream, can use water to make droplet projectiles which have a strong impact and can also expand to envelope the victim holding and drowning them at the same time, as seen when capturing Isana to lure Parade out.

Mistleteinn also has two leafy stem like tendrils which she uses as ranged and close combat weapons, as we seen her fight Merry with them and she extended them to great lengths to stab Engi whilst she was flying and using her own projectile sword attacks. The stems are very sharp and lethal as they were shown to pierce even Leon's metallic armor and later slice him in half.

There is some plant like weapons in Mistleteinn's arsenal and she used it to summon spear or stave like weapons. These like the tendrils are used for both long and short range attacks. These weapons are created by crimson petals which make frequent appearances when we meet Mystletainn. We also see Mystletainn use plants to do her dirty work as she creates seeds which grow into enormous flowers which Mr.Ijima calls the 'Bud of Despair', "in which nothing but hopelessness exists". Mystletainn also uses sharp bud like projectiles which she fires at Yumeji.

In a bid of desperate defense, for fear of death, Mistleteinn displayed an ability to swallow whole other dream demons. It is unknown if there is a size limit however she appeared around Pallette appearing swollen around the abdomen till she compressed her body into regular size. Upon doing this she informed Merry and co. that if she was defeated then the demon inside her would be also.

As mentioned previously, Mistleteinn is in a league above the average dream demon, in the sense that her power, speed and defence are exceedingly high. This is verified when we see her counter Merry's fists with a single finger and also breaks Engi's swords with one finger. Also her defense is incredible as when Yumeji attacks her with one of Engi's swords its breaks off her side indicating that she may much more tougher than the sword and when Engi lands several attacks on her, Mistleteinn remains unharmed adding "Is that all you can do?". Mistleteinn's speed is also superb as she easily dodges the combined attacks of both Merry and Engi.

What's more, Mistleteinn is omnimalevolent, making her the most evil Dream Demon to exist since she's born from all evils of Human dreams. In full context, she's universally evil (meaning she's all malevolent in nature). Trait wise, she's devoid of all redeemable traits, complete and utterly ruthless, fraudulant, and beyond unforgivable (except to users of Omnibenevolence and Omnineutrality, and especially Deities).





  • She, along with Ryota Ijima, Chizuru Kawakami, Lestion and Parade are anime-exclusive characters.
  • Despite appearing first, her physical appearance resembles Shalltear Bloodfallen from Overlord. Due to the fact that both almost have the same dress, facial structure and hair color.
  • Her name is based on a plant called Mistletoe which makes sense since she controls plants as her arsenal in the battlefield.
