Asuramaru

Asuramaru 「阿修羅丸, Ashūramaru, lit. "Perfect Asura"」 is a high-ranked possession-type demon of the Black Demon Series. He formed a contract with Yūichirō Hyakuya and became his Cursed Gear in Seraph of the End: Vampire Reign.

He also appears in Seraph of the End: Guren Ichinose: Catastrophe at Sixteen as the cursed gear of Mahiru Hīragi.

His name as a human and a vampire was Ashera Tepes.

NOTE: His name is spelled "Ashuramaru" in Catastrophe.

Appearance
Asuramaru appears as an androgynous adolescent male with long dark purple hair that goes beyond his feet while his bangs covering his left eye. As a vampire-gone-demon, he has red eyes, fangs, and pointed ears.

He wears a headband formed of two parallel golden strips that match the horns piercing through his hair from the edge of his hairline. The horns grow larger once the curse restraining him loosens.

He wears a sleeveless open-back dress including a collar with gold beads covering his throat. The chest piece is black while the rest of the dress is white, and the gown splits open at his outer thighs which frees his legs for movement. He wears black sleeves separated from the gown that reach his mid-upper arms and come down to his middle fingers, where each sleeve is attached to a ring. He is barefoot.

As Asuramaru exists as a mental concept, he can appear as anyone within Yu's memories he chooses. He often takes the forms of the 12-year-old Mikaela Hyakuya as well as Akane Hyakuya, the other Hyakuya orphans, or even Yūichirō's parents. He chooses his forms depending on what he believes will be best for breaking Yu's will.

Personality
Asuramaru is a blood-thirsty demon who was originally a vampire. He delights in drinking Yu's blood and goes into a giddy high after Yu feeds it to him for the first time. As a possession-type demon, he is described as particularly nasty and aggressive.

Like all demons, he is manipulative and uses nightmares to consume the one he possesses in order to take over his host's body. At the beginning of the series, he interrupts his host's dreams every night, making Yu tired during the day. After all, the only reason he allows Yu to borrow his power is for the future opportunity to take over his body.

After Yu loosens the curse on him and the two battle for dominance, Asuramaru eventually gives in to his compassion and submits to him. He also stops giving Yu nightmares.

Even so, Asuramaru thinks of humans as vile, greedy creatures who are even worse than vampires and demons. He considers them to be taboo-breakers who will destroy the world, and also thinks no better of angels as he considers them to be disgusting. Although he is fully aware of Yu going insane on the battlefield and of the experimentation done on him, Asuramaru does not reveal any of these vital secrets to his host. Asuramaru is more of a trusted enemy rather than a friend or ally.

History
Prior to Catastrophe, Asuramaru was a vampire known as Ashera Tepes and is from the same family as Third Progenitor Krul Tepes. He gets convinced by the First Progenitor to travel with him to the island that will become Japan and become a demon as he must "go for their future". His disappearance with the First Progenitor prompts Krul's search for him.

Many years after his rebirth as a demon, Asuramaru is sealed within a katana by humans and chained in place by a curse where he becomes Mahiru Hīragi's weapon. After Mahiru's death, he becomes recognized as part of the Black Demon Series.

Book 1
Though unnamed at the time, Mahiru uses Asuramaru against Guren Ichinose during the Brotherhood of a Thousand Nights attack on First Shibuya High School. At some point, when Mahiru's human self struggles to take back control of her body, Asuramaru uses his demon curse through the sword to infect her arm that is wielding the sword before Saitō covers it with his chains. Asuramaru is then used to cut Guren's sword before Mahiru leaves.

Book 4
Mahiru summons Asuramaru to slay a vampire that tracked her to Tokyo.

Book 5
Asuramaru is being used by Mahiru to fend off four vampires on the freeway, but ends up getting separated from her when the latter gets captured. Guren then finds him somewhere in the huge car pileup that resulted from Mahiru and the vampires' battle before the demon katana immediately vanishes. He then appears suddenly in its sheath at the love hotel Guren and his squad were staying at, as it's revealed that instead of vanishing back at the freeway, Guren's cursed weapon, Noya, actually took Asuramaru and had been holding onto it. Asuramaru comes at Guren, but was smacked away by Shinya which separates the blade from its sheath. The sealed demon fills the air with a sharp piercing crack before lodging itself into the ceiling.

Book 6
Asuramaru was taken by Guren to be experimented on by the Hīragis which led to them learning more about demons.

Second Shibuya High Arc
Asuramaru first appears in Chapter 6. Lieutenant Colonel Guren Ichinose takes his new recruits into a ceremonial room where the Black Demon Series weapons are located. To enter the contract ceremony, Yūichirō Hyakuya selects Asuramaru's sword before entering the spell circle and draws the blade to begin the contract ceremony. Asuramaru immediately thrusts Yu into an illusion where he is surrounded by his slaughtered family members. He approaches Yu in the form of a 12-year-old Mikaela and accuses Yu of abandoning them. Yu warns him not to use his name like that and calls him out as a demon. He says for it to stop pretending to be his family. Asuramaru comments that he thought he was touching his most tender memories and finds it strange that Yu didn't even flinch. Yu exclaims that he knows how demons work and orders him to give up and give him power. Letting the form of Mika collapse, Asuramaru rises as a black formless mass and stabs Yu. He realizes that Yū fought a low-rank Myo-o demon before. The demon asks why he wants power so much; if its for his revenge. Yu says yes and Asuramaru asks if it's because he lost something precious. Yu says yes again, saying that the kids from the orphanage were the first real family he had and he lost them.

Asuramaru says he will lend Yu his power as he likes strong desires. If Yu wants power for revenge alone then he will give him unlimited power. But then Yu hears someone say that it's not enough. Yu turns his head to see the corpses of the children from the orphanage lying on the ground behind him. Akane says that he has to live for revenge in truth now or else they can't give him power. He then hears Mika telling him to give up his love as they hate that more than anything. They like greed and can't stand love. They ask him if he is going to go off and make new friends and be happy without them. Yu tries to explain but Mika says that it's not fair that Yu was the only one to survive and that he left them to die.

Yu tells Asuramaru to shut up and just give him his power because he needs enough power to protect everyone. He glows brightly, surprising Asuramaru. He comments about Yu's incredible contradiction of love and lust and states that this is the reason why humans destroy the world. He says Yū interest him and he will obey him as long as his heart remains strong and warns him the moment he senses any weakness, he will take over Yu's body. He asks if Yu agrees with this and he does. He tells Yu that he will be his then and tell Yu his name and when he wants powers, just call out his name.

Asuramaru informs Yu that he is 1/10th not human and suggests humans modified him in some abnormal way. He comments that humans are more frightening than vampires, and even more frightening than demons and finds it odd to explain it to a human. When asked, Asuramaru refuses to explain and declares that their contract is complete. He says to Yu that he will be his power as well as his blade. He then tells Yu to open his eyes and let his greed grow. Finally he tells Yu to slice the world open.

Shinjuku Arc
At the beginning of chapter 8, it is revealed that Asuramaru has been tormenting Yu in his dreams every night since Yu formed the contract with him. He takes the form of Mika and accuses Yu of leaving him behind.

Post-Shinjuku Arc
At the end of chapter 13, Yu meets Asuramaru when the drugs he ingested take effect and force him to transform and lose control. Yu asks if Asuramaru is trying to take over, and Asuramaru denies it. He calls Yu monstrous and states that Mika was right. He says the two should run as far away from humans as they can before Yu loses his humanity altogether. Then, he says they are out of time after all.

In chapter 20, Yu battles Asuramaru for over 20 hours in order to take his power to the next level. Asuramaru giggles and gasps with delight at the taste of Yu's blood, making Yū calmly respond that Asuramaru is acting like a vampire. Asuramaru tells him that demons are the mere shadows of what used to be a vampire. He wants Yu to give him more of his blood, his body, his mind, everything before leaping at Yu. Chains start binding him, restraining his movements. Yu asks him about the chains holding Asuramaru prisoner and he explains to Yu that it's the sorcery that humans completed in order to curse the demons and bind them and they are trapped by it. Yu asks him if it's painful. Perplexed, Asuramaru denies any pain. He wonders why Yu would worry about him and Yu responds by saying that doesn't he hate painful things. He says that of course he does and calls Yu weird.

Yu goes back on topic and asks Asuramaru what he should do as heard that if he sucked his blood, the Cursed Gear would advance. Asuramaru tells Yu that when he drinks blood, the demon curse's restraining force goes down. He says to move on even further, he needs to explain a variety of things to Yu. When Yu is confused by this, Asuramaru says that the explanation about this curse and the contract was something that the humans decided. If he doesn't tell Yu, he'll be stuck in the demon curse chains and won't be able to move. Yu asks if it's a man made curse and Asuramaru says yes and that human sure are scary because they keep putting their hands on forbidden techniques. He also says that the thing inside Yu is quite terrible as well. Yu does not remember losing control and Asuramaru laughs, saying that humans sure are terrible.

Disregarding it as something that has nothing to do with him, Asuramaru explains the rules to loosen the demon curse binding force. Simply put, he will attack Yu and every time he takes one of those attacks, his willpower will go down. If Yu's willpower goes down, he'll be taken over. Yu finds it odd that it is essentially Asuramaru trying to take over him. Asuramaru tells him that its a demon's objective to and only reason why they listen to humans. Asuramaru then tells him that if Yu is able to cut him with the sword, his own willpower will go down, and that if Yu crushes his heart, it's game over and he wins. He warns Yu that he won't even be able to touch the sword before he starts to break the chains. He tells Yu that because he explained the rules, the curse's restraining force weakened. Asuramaru is almost totally free of the chains and wants to start the fight so they'll see who the real master is. He keeps talking about the restrains weakening, and his reasoning is fading. He wants Yu's everything and then tells him to die. He then attacks Yu, knocking him back. He gets on top of him and teasingly asks him if he is in pain but he says that he won't let Yu die. He reiterates that Yū will have a nightmare every time he takes one of his attacks and his spirit will be brought down. He wonders how long he will last.

The illusion shows Mika calling Yu terrible for leaving him behind and Akane saying that it's the reason why Mika was turned into a vampire and that it's all his fault. Yu coughs up blood but breaks free, telling Asuramaru that he won't give in to something like that. Unabashed, Asuramaru says he will as the demon curse has gotten weaker and so he'll touch Yu's true darkness and let his rages and desires run wild. He then bites Yu which shows him another illusion.

Yu appears as a child, when he was still at home with his parents. In a room with a tipped-over table and bottles on the floor with papers, pens, and drinks spilled, Yu faces his parents. His mother kneels on the ground in the kitchen with her back to him while his father curses him, calling him demon spawn. He says he must kill the Seraph of the End as soon as possible or else the world will be ruined. Yu notices his dad holding a large knife and tries pleads with him, saying that he'll be a good kid. He dad says that killing Yu is the right thing to do. Yu cries that he's not the devil and his dad chases Yu into a massive apartment hallway, where he sees Akane and Mika again. Mika says that because Yu ran away, he became a vampire. and Akane wishes that Yu hadn't come to the orphanage since everything's gone horribly wrong since he came and that he should've just died here. Yu's dad appears in the doorway and says for him to die as this is the end for him and that he will disappear here. The illusion of his dad stabs Yū through his back and left chest.

Yu says he will not go berserk over something like that. He talks about the promise he made to Mika as he was the first person to ever need him. He visualizes a kind 12-year-old Mika who says that they'll protect their family and that he'll be counting on him. When he asks Yu if it's alright with him, Yu says that it is because Mika wanted him. He'll definitely save him. Yu wakes up with tears in his eyes.

Annoyed, Asuramaru thought that he had won and Yu says that he already knows how to fight. Yu summons the sword and Asuramaru compliments him but tells him not to kid himself, noting that he must have gotten weaker, he even calls him a demon that wasn't wanted by anyone and discarded by his parents. Yu tells him that those kinds of words don't hurt him anymore and that he is fine with being a demon. He says that if Mika, Guren, Shinoa, Yoichi or Kimizuki need him, he doesn't care about something like that. Asuramaru says that him being defiant kind off annoys him and Yu asks him what he's gonna do about it and Asuramaru tells him that he'll kill him. Yu throws away his sword, deciding against attacking Asuramaru, saying that if he did, Asuramaru would see a nightmare like he did and he does not hurt his friends, which makes Asuramaru laugh. He says that Yu is being naive but Yu says that he doesn't care if Asuramaru is a demon as he needs him. Yu asks him to be his friend in order to save Mika and his family. In exchange, Yu says he will be Asuramaru's friend since Asuramaru must be awfully lonely. Asuramaru agrees to let Yu possess him. He tells Yu to grab the sword and when he does, he feels the power flowing through him.

Yu can now perform Asura-Kannon.

Nagoya Arc
In chapter 34, Yu coughs up blood after overdosing on pills to increase his power at the end of the previous chapter. Inside his mind, Asuramaru, calling him hopeless, comments on how Yu appeared to give up on revenge and then became obsessed with living and family. He asks Yu if he wants power that badly. Yu says he does need power to save Guren. He begs Asuramaru to give him power.

Asuramaru says yes. If Yu wants power, he’ll give him all he asks for and more since he feeds on ugly human emotions like obsession and greed. However he complains that the pills Yu took before are a problem as they force the curse to go crazy while keeping his greed in check. Asuramaru says that the contradiction won’t do. He states that Yu cannot expect to just take drugs and get stronger without any consequences so Yu asks how he can get stronger.

Asuramaru says he can’t answer that as Yu is already dead. He says that it was a quick death. Yu took so much of the drug that all his internal organs ruptured and his heart exploded. He says while he has powerful regenerative abilities, but that kind of damage is beyond him. He says Yu’s done. Dead. Then, he amends his statement, saying that at least he should be.

The only reason he isn’t is because of those disgusting angels. Their power is forcibly keeping him alive. They peer into the background of Yu's mind and see something lying on the ground. Yu asks Asuramaru what it is. He says he doesn’t know but from there it looks like a trumpet. Yu has the urge to take the trumpet, but Asuramaru warns him not to take it and insists that Yu take him instead since angels can be far nastier than demons.

Asuramaru notices that Yu’s heart has starting beating again and says that now that it’s fixed, he can take care of the rest. He stabs into Yu's abdomen, telling him not to go with the trumpeters and instead stay with him, accept him. He tells Yu that he can heal him but when he tries to he says that he cannot return Yu to normal. He complains that Yu lost even more of his humanity than before and has become even uglier. Asuramaru orders him to never do that again and claims Yu's body is his. Yu says he does not care and demands for Asuramaru's power. Asuramaru calls him a greedy little human wretch and tells Yu that he has already given it to him as three pills worth of the drug is in effect. He can use all his strength for the next two to three minutes without becoming a demon. Asuramaru then tells Yu to awaken. During Yu’s fight with Crowley, he demands Asuramaru to give him enough power to save Guren and to save his friends. He wants Asuramaru to give him the power to protect his family. Asuramaru is delighted to help, especially now that the drug has completely worn off. Now he can give Yu all the power he desires. He tells him to need it, crave it and let his greed rule.

After they are knocked unconscious by Kimizuki, Asuramaru praises Yu’s honesty toward his desire and love and mentions how good and evil mean nothing when it comes to protecting Yu’s family. He says Yu is broken. Asuramaru tempts him with power again, but Yu turns him down.

He reappears in chapter 40. The trumpet from before rests between him and Yu. Asuramaru scolds him for being so greedy and says he does not have enough power to give them. He calls Yu a traitor and says Yu is betraying him by taking up that trumpet. He says that is the worst decision he could make and says that will erase what is left of Yu's humanity. Yu answers that he does not really care as long as he can protect his family. He blows into the trumpet and is consumed by a massive power that splits the clouds. Continuing from that, after awakening in his seraph mode, Asuramaru appears in front of him. He tells Yu not to kill the humans since he does not desire human deaths. When Yu asks who Asuramaru is, Asuramaru tells him to be silent and calls him an angel. He says he is not speaking to the angel but rather to Yu. He says he will help Yu control the angel as long as Yu draws his sword. He says that Yu may be able to contain the seraph by becoming a full demon. The seraph within Yu orders Asuramaru to be silent and says that humanity sees its end today. Asuramaru ignores him and tells Yu to let out his greed and desire. He tells him to accept his inner demon.

Yu's left hand slowly begins reaching for his cursed gear. The angel yells at the humans to stop and not reach further into the forbidden.

Yu grabs the cursed gear, and Asuramaru grins with delight. A pair of horns sprout from Yu's head. He shouts that he is going to save his family and stabs himself through the chest with the cursed gear sword. He plummets to the ground but not before Narumi catches him.

Post-Nagoya Arc
Some after the group runs from the airport, Ferid and Crowley appear to group who have found refuge in a small village. They fight for a while until Yu surrenders to Crowely and Ferid. Ferid presents Akane's head in a jar to them, sending Yu's demon out of control and making him attempt to kill Ferid.

As ge struggles against his demon, Mika orders him to suppress it. Yu tells him to shut up and says he just needs more power. He contacts Asuramaru.

Asuramaru calls Yu a greedy namanari. When Yu asks what that is, Asuramaru explains it and says that this is the third time already. Yu mentions that his memories have been really spotty lately, and Asuramaru says that his human self does not want to deal with the memories of his demon self and hides them away. Asuramaru says that he could take three pills and not die because he is no longer human. Asuramaru asks Yu to let him take over for just an instant. He says he will not kill anybody, but Yu will want to kill all of his friends. Asuramaru says he only needs three seconds.

Yu tells Asuramaru to stop lying to him because he has his own will and knowledge. Yu says he will not become a demon, and Asuramaru asks if that is his human or demon side talking since they are now inseparable. Yu says he does not really care as long as he can protect his friends, but Asuramaru says demons have no friends or family and simply kill everything.

Yu says he supposes he cannot become a demon. When Asuramaru says taking those three pills will make his demon side grow exponentially, Yu shrugs it off, saying it is fine as long as he protects his friends. Asuramaru asks if Yu can hear how much he is contradicting himself.

Asuramaru cuts the conversation short, saying that, this once, Yu will not need the pills because he is about to be rescued by a vampire.

Osaka Arc
Later when Yuu makes eye contact with Krul, he notes that he thinks he felt Asuramaru's emotions. Asuramaru claims demons don't have emotions, or he doesn't think they have any.
