Mikaela Hyakuya/Story

This article comprehensively details Mikaela Hyakuya's story from the Seraph of the End light novels and manga.

Dark Ages
At some point in the Dark Ages of Greece, Noya, Ashera and Krul look at the corpse of a "Mikaela", whom what all of them were meant to become but failed. A young Yu looks from afar having taken interest in what all of them been doing. Ashera confronting Yu gently stating he isn't supposed to be here due to Sika Madu orders. Yu is still interested as seeing that everyone being here, wanting to know their doing claiming if there is a fun toy.

Noya tells Yu he could call it a fun toy when Yu believes it to be that, annoying Krul which she gently also tells Yu to keep what he saw a secret, but the young boy doesn't know the meaning of secret, telling Noya they would be in trouble now that Yu have seen them. Noya isn't concerned about that that their secret is still safe, questioning Noya's idea, and Noya helps him see what is in the coffin before killing Yu. Angering them both, but Noya isn't concerned in the least, being a forbidden room and all and states that Sika Madu wouldn't notice them adding that he will just create more Yu's. It is unknown what they were trying to do with the "Mikaela" at that time.

21st century
When Mikaela Shindō was a child, his parents abused him. Eventually, they "grew tired of him" and threw him from a moving vehicle. Since he possessed the seraph gene, the Hyakuya Orphanage picked him up afterward. He was one of the children that were being experimented on by the religious Hyakuya Sect to create a weapon of mass destruction, as part of the "Seraph of the End" plan in destroying the world.

Events of 2012
Mika appears with Saitō in a residential neighborhood late in the afternoon. He asks Saitō if he can really buy whatever he likes. He asks what the other kids at the orphanage would want and if their teachers would be mad if they brought back ice cream. Saitō says he does not see any problem. He gives Mika a 10,000-yen note and sends him over to the supermarket. A few minutes later, Mika returns and asks Saitō for help because he bought too much for him to carry on his own.

He asks Saitō who Guren is and he says that he doesn't know him and thought that Mika might know him but Mika says he doesn't. Saitō tells Mika to watch out because Guren might be some kind of pervert. Mika agrees as he says Guren looks pretty creepy. Both he and Saitō leave and head back to the orphanage. Later, Mika races Akane and the other orphans to the park. He recognizes Guren as the man Saitō describes as the neighborhood pervert. He runs up to Shinoa to see if she is alright, and she milks the situation by saying that Guren told her all sorts of dirty things and that he was probably trying to abduct her. Mika threatens to call the police, but Guren leaves.

The Hyakuya consider him to have an exceedingly high-grade body for experimentation and refused to give him to Mahiru Hīragi. Their notes document him as acting as a leader of their orphans. Mahiru notices he had impressive charisma among them.

Mika sends Akane to investigate if Miyuki Yamada, who is actually Mahiru Hīragi, is a nice person since she is adopting Junji Haiyama, a four-year-old boy at their orphanage. Since Mahiru's face lights up while thinking about Guren, Akane decides she must be a nice person. After Mika calms Junji down, he instructs Mahiru about some of his behaviors, and Mahiru leaves with Junji.

Prologue
When Yu arrived at the Hyakuya Orphanage, Mika wanted them to be friends, but Yu was uncooperative. Mika claimed he was the leader and picked a fight with Yu, but Mika easily defeated him. Afterwards, he told Yu that he used to be alone like him, but now he had a big family, and that from that day on, he had one too. Mika told Yu that they were not lonely because that day was the day their brother Yu joined them.

Witnessing the director at the orphanage suddenly begin to bleed from her nose and mouth, Mika saw her feall to the ground. The virus struck down the adult population of Tokyo while Third Progenitor Krul Tepes led the invasion of their city. This was Christmas of 2012.

Events of 2016
After remembering his parent's death, years later, Mika wonders what his mother meant when she said he was a chosen child with the special name of Michaela. He lives on as vampire livestock.

At some point Mika was using the lavatory when Yu knocked on the door. Asking what, Mika responded that he was not done, having just sat down. Questioning if Yu has to go, hearing no, Mika wonders why did he knock on the door. Unsure what Yu is holding when asked, Mika is startled when it appears as if there is a key being placed into the door knob. Calling for him to hold it, Mika asks if Yu is not going to unlock the door again, and to quit it with that. Stating that he was almost done, Mika told Yu to quit it.

In Sanguinem, Mika donates his blood, cringing as the needle pierces his neck. He chats with Yu, who is sitting next to him. Mika thinks Yu is kind because he always maintains the children's hope about defeating vampires. Mika wonders how he can get a future for the other children. He recalls Ferid Bathory, who is a seventh progenitor and is rumored to have children frequently visit his residence. Unlike the other vampires, he is interested in humans and would even help them improve their livelihood. Once they finish up and leave, Yu asks him what is wrong and says Mika is spacing out. Mika only says he feels tired after donating blood. Yu prattles on about killing vampires again before telling Mika to not carry everything on his own shoulders. Mika knows that one wrong move will get him killed, and he cannot risk Yu dying.

Mika tells him not to worry and asks what Yu's surname is, but Yu cannot remember. Yu asks Mika about his family since he does not look Japanese. Mika's mother was Japanese but his father was Russian. Mika says his last name was Shindō. Mika says all of the orphans use the surname Hyakuya because they are all family.

He thinks about the "special" name Mikaela and looked into it after his parents died. He knows it is a female variant of the name Michael but has no idea what his delusional mother was talking about all those years ago.

Mika sees Ferid's mansion and splits off from Yu. He says he is going to get food from Sakuma's group and that Yu cannot come because he started a fight last time. In actuality, this is a lie, and Mika intends to visit Ferid. Later on in the intermission, Mika is at Ferid's mansion. He recalls that there is a rumor about children disappearing here. Regardless, he knocks on the mansion door. The inside is magnificent. A girl shows him in and says he is Lord Ferid's special favorite. There are many toys inside. There is a garden outside filled with many colorful flowers.

The girl addresses Lord Ferid, who then rises out of the flower bed with trails of blood dripping from his lips. A young boy also emerges. When he sees Mika, he covers his neck in shame. Ferid tells the boy he may now leave and can take anything he likes from the grounds. The boy thanks him graciously and runs off. The girl leaves as well.

Mika says he heard he could get benefits from Lord Ferid if he came, and Ferid says that is true as long as Ferid likes him. Mika thinks of the Hyakuya orphans. Mika asks what he should do to get Ferid to like him, and Ferid says he has already taken a shine to them. He praises Mika's blue eyes and golden hair. He asks Mika's name and then calls it a good one. Mika says he is not very fond of his name.

Ferid says that, in the past, his master called him "Michaela."

Ferid bites him, and Mika feels a humiliating immoral pleasure mixed with pain. He becomes weak and concerned he might die. Ferid stops, saying that he nearly drank too much. Mika falls to the ground and is unable to stand up. He struggles to breathe.

Mika decides he absolutely cannot bring Yu or the others here. Mika realizes he is crying.

Ferid tells him to eat in the dining room and then return. Mika wipes his tears and smiles.

Mika sees the abundance of food. Instead of eating there, he pictures the smiling faces of his family and takes fruit with him. Once he returns home, the children ask him while he is late. Mika decides that he will grin and bear it, no matter how horrible this place is. The children see the grapes and become very excited. Mika reflects that he got involved in a journey that is over two thousand years old.

Prologue
Later, he is with Yu as children are having their blood taken by the vampires. Whilst Yu is angered, Mika explains that there is no way humans can expect to beat vampires with strength. He contemplates a different approach on how to handle their situation. After, Mika sees and approaches Ferid Bathory, and offers his blood in exchange for food and money. Although he used the money to buy ingredients to make curry for the other children, his real goal was to steal a map of the underground city from Ferid's mansion. He eventually succeeded, stealing both a map and a gun.

Using the map, Mika and Yu attempted to escape with the rest of the children from the orphanage and even reached the exit. However, Ferid anticipated their actions and awaited them at the exit. He gleefully informed them that the map was correct, and he would have a hard time following them above ground. When the younger children ran, Ferid cheerfully slaughtered them in front of Yu and Mika, claiming to enjoy the look of despair on their faces. In order to buy Yu time to escape, Mika charged at Ferid with the gun. When Mika attempted to shoot him, the vampire punctured Mika's chest with his claws and then tore off Mika's right arm, which was holding the gun. Yu refused to run away and caught the gun, managing to shoot Ferid in the face. Although Yu incapacitated Ferid, Mika was fatally injured and could no longer escape. When Yu refused to leave Mika's side, Mika pushed him away until Yu finally fled to the exit. He felt relieved that at least Yu managed to escape and happy that Yu finally called him family. With those thoughts, Mika was prepared to die in peace.

Becoming a vampire
Just then, vampire guards and Krul Tepes arrived shortly afterward. Krul claimed that Mika belonged to her. She interrogated Ferid, and his taunting responses led her to rip off his arm and crushing his throat on the floor with her heel. She spared his life, and he waved his arm at her, promising to return. Krul asked Mika if he would like her to grant him eternal life, but he refused the offer. Even though he expressed no desire to live, she bit her lip and forced her blood into his mouth through a kiss, ending his human life and turning him into a vampire against his will. He was held by Krul as he ceased being human. After becoming a vampire, Mika refuses to drink human blood, which will complete his transformation into a true vampire, granting him eternal youth and immense power. Resisting his thirst causes him tremendous pain, but he claims he would rather die than become a vampire. Krul warns him that a vampire who does not drink blood will turn into a senseless, raving demon. Since Mika refuses so adamantly, Krul slices her own wrist open to offer her own blood. After all, her blood is not human blood. As he drinks it, she claims he will never be able to leave her, and he will be her dog for all time.

At some point Mika was sparring with Krul and knocked back by her. Mika refused to say anything no matter how many times he was struck. Stating that it did not hurt Mika said that he could keep going. Readying his sword Mika requested that they begin again and resumed the practice.

Second Shibuya High Arc
He reappears at the end of chapter 2 in 2020 as a vampire. Despite being a vampire, he continues to grow and age since he has yet to drink human blood. Ferid finds him in a chapel within the Vampire Third Capital of Sanguinem and notes that Mika comes here often. Mika points his sword at Ferid's neck, but Ferid is unconcerned. He tells Mika they found Yūichirō Hyakuya, who he says is being used by some very nasty humans are using him, just like they thought. Mika reappears in chapter 5. He arrives in Sannomiya, Kobe and kills a Horseman of the Apocalypse to save a human girl as she flees for her life. The humans cheer, relieved that vampires have come to protect them just like in Osaka. Lacus Welt complements Mika on his power, but René Simm scolds him for stealing the glory and kill for himself. René states Mika's greedy human roots show through as clear as day. Mika denies it, saying that he does not care about glory and says that René can have it. The vampires shrug. They announce they will protect the humans that they will protect them in exchange for their blood. In the meantime, the human girl presents her neck to Mika, offering him her blood. Mika blushes and swallows. Later, we learn he refuses the offer. During a meeting of nobles in Sanguinem, Mika enters the grand hall. Noticing him, Krul smiles and Ferid waves. Krul and her speaker announce war against the Japanese Imperial Demon Army for the crimes of killing their compatriots, stealing their territory, and delving into forbidden magic. The humans are even experimenting with the "Seraph of the End." Mika says he will save Yu.

In chapter 7, Mika, Lacus, and René fly to Tokyo to invade Shinjuku.

Shinjuku Arc
In Shinjuku, Ferid commands the attack with Mika at his side. Lieutenant Colonel Guren Ichinose spots them, and Ferid comments on it shortly afterward. He tells Mika not to worry about it and advises that Mika drink some human blood since battle is their only opportunity to drink it from the source, but Mika tells him to shut up and says it is none of his business. Ferid reminds Mika that vampire law dictates that they cannot directly bite and drink blood from humans in the city, but Mika points out Ferid had no regard for that law when he drank Mika's blood four years ago. Mika recalls when Ferid slaughtered his family for entertainment. Ferid asks him if he is still angry about an incident so long ago, despite being a vampire now. Mika denies it, stating that he is only angry at himself for failing to protect his family, but he is clearly angry about the topic. Ferid comments that Mika is always so hard on himself, and he teases him about Yu. He once again tries to convince Mika to drink human blood, but Mika ignores him and walks away. After becoming thirsty while watching another vampire drink, Mika quenches his thirst by drinking Krul's blood from a test tube. Guren storms onto the battlefield and kills many vampires in a single attack. Ferid orders Mika to join him in killing Guren, but Mika claims he can handle Guren on his own. At the Shinjuku 5th Street intersection, Guren and Mika clash. Although Guren complements Mika's strength, Mika responds by saying Guren is not very strong. Guren uses a fudo myo-o spell to cause an explosion. Mika dodges easily, but Ferid warns Mika his arrogance will be his downfall and offers his assistance once more. He points out that Guren never planned to fight Mika one-on-one. Shigure set a trap, but Mika manages to escape. With the help of Goshi's illusion, Guren attacks Mika from behind, claiming checkmate; however, Ferid steps between them and blocks the attack. He backhands Guren and sends him flying. Ferid warns Mika that humans are exceptionally determined greedy cowards and must be fought cautiously. He proposes fighting Guren together with Mika, but Mika promptly rejects the offer. Mika says he knows how the humans work now and commands his sword to drink more of his blood. Ferid comments on his arrogance and wonders if that is a lingering remnant of being human. Mika lets Guren talk for a few seconds with his team, and Guren decides to take a second potentially lethal pill. However, Mika attacks him before Guren can ingest the medication. When Guren asks if Mika has gotten faster than before, Mika claims he stopped holding back. Guren calls him a naive brat. Mika defeats Guren and stabs him through the chest. Enraged overseeing Guren get stabbed, Yu arrives. Mika recognizes him and turns around, but Yu pierces Mika through the chest with Asuramaru, calling him a bloodsucker and telling him to die. Then, he recognizes his not-quite-dead best friend and family member. Mika does not try to defend himself.

Guren grasps Mika's sword with a spell tag and urges Yu to activate his weapon and kill the vampire, but Yu freezes when he realizes who he just stabbed. Mika releases his sword and escapes. Guren hits Yu and asks him why he did not kill that vampire when he had the chance. While Yu reveals Mika's identity to his squad, Ferid chats with Mika. Ferid says that Yu is obviously being used by those humans, and Mika claims he will save Yu. When Ferid mentions a human-like Yu could never be one of them and volunteers to turn Yu into a vampire, Mika grabs Ferid's collar and threatens to kill him. Ferid says he was just kidding, and he says he will keep the humans busy while Mika rescues his "beloved princess." Crying, Yu calls out Mika. Then, Thirteenth Progenitor Crowley Eusford arrives. Ferid changes his plan from killing Yu's human allies to turning them into livestock. The skirmish begins, and Ferid steps behind Yu and grabs his shoulder, causing Mika to amputate the responsible appendage. Of course, Ferid says he was just joking about tasting Yu. Mika steps up to Yu and tells him to forget about the humans and run away with him. He then lifts Yu and carries him in his arms. Mika warns Yu that he is in a bad place and is being used by the humans, but Yu has no idea what he is talking about. Yu struggles and breaks free, jumping to the ground. Yu says that Mika makes it sound as though he is no longer human and he is asked if it is his fault, which Mika immediately answers that it is not Yu's fault. Mika begs Yu to come with him, insisting that he is Yu's only true friend and the humans are only deceiving and using Yu. Yu looks back when Shinoa screams and sees his comrades defeated by the vampires. When he tries to help them, Mika grabs his wrists and says they have to go. Just then, the special supplement Shinoa gave Yu under Guren's orders takes effect, causing Yu to transform as his seraph component runs wild. Yu screams. Yu swings at Mika and Crowley before moving to kill Shinoa, his true target. Mika jumps in the way, and Yu stabs him through the back. Mika urges Yu against killing humans, and asks Shinoa how she could dare use Yu like that. The berserk Yu calls Mika a vampire, telling him to not interfere and saying that all humans must be killed. Guren orders Shinoa to embrace Yu to undo the transformation, so she jumps in after Yu flings Mika aside. Yu coughs blood, and Mika curses the humans, wondering what exactly they did to him. Human reinforcements arrive, and Ferid orders Mika to retreat. He says Mika cannot save Yu right now and says they should go home. Mika refuses to leave Yu, so Ferid grabs Mika's neck and tells him that he should shut his mouth like a good boy. Ferid grabs Mika around the waist and carries him away.

Post-Shinjuku Arc
Later, Mika cries in his sleep during his curse detoxification. He wakes up surprised and mentions he has not cried since becoming a vampire. Lacus asks Mika about his condition and says that Mika sustained the worst injuries of the battle, but Mika ignores him. Lacus brings up the "Seraph of the end," stating he heard it troubles even the Progenitor Council. He asks Mika about that monster (i.e. Yu) and if his connection to that thing is why Krul favors Mika. Mika ignores him. Finally, Lacus asks what exactly Mika himself is, and Mika answers that he just an ugly bloodsucker. Krul summons Mika to the Royal Audience Chamber over the intercom. Lacus taunts Mika by calling him the queen's pet. In a meeting with Krul, Mika promises to save Yu.

In chapter 19, as children play nearby, Mika sits on the streets of Sanguinem, sweating and gasping in pain as he fights his thirst for human blood. He says Yu's name and mutters that it hurts. In chapter 22, Ferid pesters Mika about drinking human blood again. He says Mika ages because he has yet to drink human blood, but Mika is still just barely at the age Ferid finds most beautiful. He suggests Mika halts his growth at its best point and says it will make Mika feel better. He plucks a child named Dai off the street and punctures the surface of his neck with a thumbnail to make it bleed. He tempts Mika with the human blood; however, Mika resists his desire to drink and grabs Ferid's arm instead. He tells Ferid to let the boy go and states that drinking directly from a human is against vampire law. Ferid drops the child.

He asks Mika why he avoids drinking human blood so much. He asks if it is because Mika hopes to become a human again one day, but Mika tells him to get lost. Ferid then smiles and asks if Mika is afraid Yu would hate him for drinking human blood. Mika does not respond. Unable to resist his thirst any longer, Mika enters Krul's chambers. She is filling up a vial of blood for him when he attacks her, biting her neck and shattering the vial, spilling its contents on the floor at his feet. Mika gulps her blood down and Krul embraces him. When Mika comes to his senses, he pushes her away, apologizing for losing control. Krul accepts his apology and says any vampire would act that way when parched for blood. She says that vampires, unlike humans, desire blood alone. He then looks downward and sheepishly asks her for a greater stock of blood. She teases him for being rough with her and orders him to report on the attack against the Shinjuku humans. Mika insists she owes him an explanation first. During a recent Progenitor Council Meeting, the high-ranking progenitors summoned Ferid to report on the battle in Shinjuku. Although any progenitors ranked lower than sixth are normally barred from their meetings, Ferid was the highest-ranking vampire on the battlefield and acted as the commander. Ferid shows a video of Yu transforming. He alerts the progenitors to the fact that humans are weaponizing the "Seraph of the end" once again. Alarmed, a fourth progenitor comments that Krul should have destroyed that plan when she destroyed the Hyakuya Sect in Japan eight years ago. Krul claims she eliminated the entire Hyakuya Sect along with each of guinea pig in their orphans who bore the seraph gene. Third Progenitor Lest Karr picks a fight with Krul, saying she has mishandled her management of Japan. She says she does not fail and says she will deploy their full army to kill every human in the Japanese Imperial Demon Army.

One council member notices Mika behind Ferid and asks who that child is. Ferid states that Mika is his favorite servant as of late, and he cannot bear to let Mika leave his side. No one actually states Mika's name. One progenitor begins yelling at Ferid to scold him since Mika is certainly not permitted there and Ferid himself is permitted only because of special circumstances, but another silences the scolding and says that Ferid has always had flights of eccentricity. The meeting concludes. Krul slashes at Ferid for his misbehavior, asking him if he is trying to dethrone her. Ferid hides behind Mika and says she would be the first suspect if he dies. He has blackmail against her since he knows about her involvement with the seraph of the end, and he says these secrets may be sent to the Progenitor Council on his death. She glares at him, and he says her adorable face makes his heart flutter. Since he is responsible for Yu's escape, he says he would face even worse punishment if he is discovered. He then joyfully concludes he and Krul are actually partners in crime since they share the same secrets. He tells her to take his hand and submit to him but then states he is just kidding. He promises to be back later, pats Mika on the butt, and leaves.

In the present, Mika asks Krul what her objective is since letting him and Yu live jeopardizes her position. She tells him he does not need to know, but he becomes upset and concerned that she may be trying to use Yu for her own ends. Krul asks what he could possibly do to her and intertwines her fingers with his, squeezing his hand and making him crumple to the ground. She reminds him she can easily extinguish his puny life, and he is even dependent on her blood. She asks if he would rather die than be his tool. If he dies, then would Mika abandon Yu to those foul humans?

She says human foulness is not limited to any locale or group and asks if he will abandon Yu to his fate. He says he cannot follow her anymore, but she calls him selfish and says he cannot defy her. She says she likes both Mika and Yu and tells Mika to trust her, and that she is his savior, surrogate parent, and owner.

Giving into his pleading, she whispers her plans for Yu in Mika's ear. Startled, he asks if she is serious. She gives him orders to get "lost" in the ensuing war, hiding from both humans and vampires, and to find Yu. Mika obeys.

Nagoya Arc
In chapter 23, Mika, René, and Lacus wear their new uniforms and discuss orders to deploy to Nagoya. Then in chapter 26, Lacus accidentally kills a human child in front of Mika. He says drinking blood feels so good he always forgets to stop before they die. He tries to convince Mika to drink since they can only drink from the source while outside, but Mika says he does not need any. Lacus comments on Mika's small appetite, but René says he is unconcerned as long as Mika does his job. Their current assignment is to herd livestock from the surface and present them to the nobles of Nagoya. When Mika begins sweating and breathing more heavily from his thirst, Lacus asks him if he is not even going to take a sip. He warns them that nobles have different laws for their domains in Nagoya, and they may not be free to drink there. Mika lies and says he is not interested in human blood, but Lacus says that cannot be. When he asks what Mika is interested in, Mika walks away and attempts to parch his thirst with Krul's blood. His entire body hurts because he craves blood so badly, but he intends to keep holding back on his thirst since he has held back this long.

Unfortunately, Krul's blood is ineffective at stemming his craving. Mad with thirst, he attacks a young human girl and pins her to the ground. When Lacus comments that Mika is going to drink after all, Mika flinches. One of the vampires tells him to be quick about it, but Mika just lets the girl go. She runs to her brother, and the siblings stare back at Mika with fear. Mika says he does not need any blood, and the chopper takes off with the humans. As the three vampires head toward Nagoya, Mika plans to resist human blood at least until he saves Yu from those humans.

Upon reaching Nagoya in chapter 29, Mika, René, and Lacus encounter Moon Demon Company Sergeant Aiko Aihara, who attacks them with her manifested bow and arrows and shoots down one chopper. Mika tells her he has questions for her, but she orders her team to commit suicide. Before she can swallow the poison herself, Mika sticks his fingers into her mouth and removes the pill. She says he can torture her all he wants, but she will tell him nothing. He tells her to shut up before the other vampires realize she is not dead, which confuses her. He tells her to play dead and speaks in a whisper. He asks her about Yu. When her expression changes, he realizes she knows something and demands she give him that information. When she speaks up, he covers her mouth. He tells her Yu has friends, but they are not those humans.

When Lacus and René talk to Mika, Mika reports that Aiko killed herself along with the other humans, surprising her. Another vampire reports that all the vampires stationed underground were killed and claim that Nineteenth Progenitor Mel Stefano was murdered by a pack of humans in military garb. René suggests they head to Nagoya City Hall since that is where the closest noble's seat is. Alarmed, Aiko jumps to her feet and puts a knife to Mika's neck in an attempt to use him as a hostage. Lacus points out that human is still alive, and René instructs him to capture her. Aiko threatens Mika's life again, but Lacus says that neither he nor René care if Mika lives or dies. Mika asks her why she moved. Aiko whispers that Yūichirō is headed to Nagoya City Hall and says all of the humans will be killed if the vampires head over there. When Mika asks why she trusts him, she says he called Yu a nickname, so she is gambling that they have a close relationship. Mika grabs her wrist and crushes it, making her scream in pain, amusing Lacus.

Mika monologues at her about her being a filthy, shameless human who betrayed her own comrades to save her own life. Catching onto his plan, she begs for her life, and he kicks her several yards. She promises to talk and says that the JIDA sent a platoon of fifty to attack the Automobile Museum and assassinate Seventeenth Progenitor Zane Lindau. René says they will be questioned if they do not act on this information, so they decided to investigate the Automobile Museum.

Aiko asks Mika to kill her before they torture her for more information. Mika tells her to do it herself, but she says that would cast everything in doubt. As Mika leaves her behind, she jumps to her feat, manifesting her Cursed Gear bow. She screams that the vampires will kill her anyway, so she will take at least one of them with her. Mika calls her a fool before slicing through her chest and ending her life. With her last breath, she smiles and thanks him.

He takes five vampires with him to Nagoya City Hall while Lacus and René investigate the false lead. Mika and the vampires with him take a helicopter. When the other vampires notice humans are attacking Lord Crowley and intend to call for reinforcements, Mikaela kills them all before they have the chance to defend themselves. This is the first time Mika is shown killing anyone in this series aside from the horseman in chapter 2. At the end of chapter 34, he waits for the battered Moon Demon Company spots and run toward him. He says it is time those humans return Yu to him. The surviving soldiers charge at him. Mika notices four transport helicopters coming toward the area realizes he must move quickly before the Kyoto vampires join the battle. Since he is facing over thirty humans, he commands his sword to drink more of his blood than usual. Mika swings his sword, but Rika Inoue and Tarō Kagiyama block his attack. Makoto Narumi attacks him from the side, but Mika blocks it.

Spotting Yu, Mika leaves them and jumps past Shūsaku Iwasaki and Yayoi Endō. Confused, Makoto comments that the vampire is making an unwise decision. Goshi says Mika is underestimating them, but Sayuri wonders if he has an objective other than attacking them. Shigure says they have to kill it regardless. Goshi summons an illusion, but Mika dives through it anyway, surprising him. Mika dodges an attack from Sayuri, but Shigure gets him with three kunai into his right thigh. Mito then punches him before he can land and sends him to the ground in front of Shinoa Squad. Mika sees Yu on Shihō Kimizuki's back. Yoichi recognizes Mika from Shinjuku and informs the others. In the meantime, the soldiers surround and attack Mika. One stabs him in the back, but Mika ignores him leaving the humans are puzzled by his strange behavior.

Shinoa calls out to Mika to identify him, but he tells her to shut up and return Yu to him. Kimizuki says they should stop him before Mika kills them which Yoichi protests. When Mika lunges at Kimizuki, Mitsuba tries to block him, but Mika smacks her weapon away. Kimizuki drops Yu while trying to block Mika, telling Mika cannot have him. Mika soon throws him aside before finally getting to Yu. As Mika holds the unconscious Yu in his arms, Yoichi jumps on his back, and tells Mika he won't let him go anywhere. Mika tells him to quit getting in his way. Yoichi says Mika can kill him, but Mika is their family so long as he is Yu's family. Mika knocks him off as well, telling him to not be stupid and die. Shinya Hīragi uses the distraction to stab Mika in the back and through his chest. He tells Yoichi that he did excellent work and this battle is over. He tells Mika to die, alarming Mitsuba and Yoichi. Shinoa activates Shikama Dōji and knocks Shinya away from Mika, surprising both of them. With her back to Mika, she explains that Yu would be mad at them if Mika were to die. She orders Mika to take Yu and run.

The other soldiers demand to know what Shinoa thinks she is doing and say they must kill that bloodsucker. Kimizuki, Mitsuba, and Yoichi join Shinoa, stepping between Mika and the other humans as well. Yoichi restates their motto: "Family takes care of family." Mika comments that family does not exist in this messed-up world. He recalls playing with his own family on the streets of Sanguinem and pulls Yu close to him. Shinoa tells Mika to hurry up and then meet up with them at Nagoya Airport. Mika asks her why he would meet up with them, but she says she decided to trust him and that is that. Her squad charges at the Moon Demon Company while Mika flees with Yu.

While escaping, Mika holds the unconscious Yu in his arms and pleads for him to wake up. Mika takes him to a ruined convenience store. While waiting for Yu to awaken and suffering from his injuries, he attacks a human child but frees him when the child calls him a monster. Mika says he does not want to become a vampire, even when he finally got Yu back. When Yu wakes up and calls out to him, Mika mutters about human blood and attacks him. While he is screaming and in pain, Yu offers his blood to him. Mika jumps on Yu but stops before biting him. Yu apologizes for leaving Mika behind, and Mika returns to his senses.

Yu wants Mika to drink his blood, but Mika refuses to become a monster just for Yu's sake which leads to the two arguments. Mika has something important he came to tell Yu, but Yu covers his ears and refuses to listen until Mika drinks his blood first. Yu cuts his wrist, and Mika complains. Yu says that drinking a little blood is not enough to turn Mika into a monster and says they are still family regardless of what Mika becomes. Mika begins crying. On Yu's third offer, Mika hugs him and bites into his neck, drinking his blood and becoming a true vampire. After drinking, Mika apologizes. Yu says it did not hurt much. Then, Yu notices Mika's eyes change color. Mika blames Yu for turning him into a monster, so Yu tells him to growl or something then. Mika says surviving by drinking blood from his own family is not normal, and he is a failure as a human. Yu says he is fine if he is not normal. He says Guren took him in and told him to live, even if his only reason was for revenge. Guren said Yu might find someone who would need him again, and he found Mika.

Yu says he does not care if Mika is a vampire now, and he will find a way to change Mika back if Mika ever gets sick of it. He tells Mika to never try to go off and die again. Mika states that he is the one who is supposed to save Yu and comments that Yu is stronger than he used to be. Mika laughs. Mika says Guren is probably just using Yu, but Yu says he does not care if either Guren or Mika want to use him. Mika sees this as too risky and says he will never use Yu. Yu points out that Mika just drank his blood. He says Mika may drink however much he needs in exchange for helping him rescue his new family.

Mika warns him against the Demon Army and draws his sword against Yu when Yu insists on finding his family. Yu states he wants to rescue his family, and Mika is obligated to help him. He says he would rather die than be unable to save his family. Mika reveals that the girl with the scythe saved them, and Mika agrees to save only those four. Yu volunteers to drive to meet with them, but Mika decides to drive instead. During the drive, Mika informs Yu about the Seraph of the End Project, the Hyakuya Orphanage, and how the Demon Army is now redoing the same experiment which caused the end of the world eight years ago. Mika invites Yu to run away with him, and Yu agrees to talk it over with the others since Mika is so set on them. He tells Mika that Mika can trust the others as much as he trusts Yu. Mika says he does not see that happening.

Mika and Yu continue to drive to Nagoya Airport, and Mika once again tries to talk Yu out of it. Mika states that the human named Shinoa is no friend of his. Yu retorts that they have already settled the matter, but Mika says he does not realize how terrible humans can be. Yu reminds Mika that Yu is human. Mika says he went overseas a few times to destroy human cults who were experimenting on the Seraph of the End. A flashback shows an emaciated Seraph child with wings for arms confined in fluid with an oxygen mask. It begs Mika to kill it, to "kill this ugly thing I've become."

In the present, Mika states that the Demon Army is the worst of them by far. Yu asks Mika what they should do as an alternative, and Mika they should get away from the Demon Army. Humans across the globe are after the Seraph of the End experiment, and experimental subjects like them would only cause trouble for Shinoa. Yu agrees and wants to at least check on Shinoa and the others from afar. After that, he and Mika will take off. If Yu's friends are safe, then they can plan how to rescue Guren. Mika immediately turns the suggestion down but soon gives in when Yu begs. He says he may be able to do something if Guren is still alive. Overjoyed, Yu repeatedly asks Mika how until he annoys Mika enough for Mika to tell him to shut up. Mika says Yu has not changed since they were children. Mika says the vampire queen kept him as a pet of sorts, and they can ask her for help. When Yu asks if she can be trusted, Mika says she does not know but will at least listen to them. Yu asks Mika who she is to him, and Mika says she is the one who saved his life. On that note, Yu immediately says they can trust her.

Mika asks if Yu has any brain cells in his head at all, and Yu says it was only thanks to her that they could see each other again. They arrive at Nagoya Airport by Chapter 40. He and Yu step into the fray, surprising Shinoa Squad and Narumi. Mika points out that humans are killing humans and tells Yu they should not have come there, but Yu disagrees. Yu asks Shinoa for orders. She issues a retreat. The survivors all request to be backup for the rear guard, but Mika says he can block chains at that speed on his own. Yu chides Mika on teamwork. When Mika asks Yu if he expects him to trust humanity after seeing them sacrifice their own soldiers like that, Yu says that he is only telling Mika to trust him. Mika, Yu, and Shiho Kimizuki block the chains coming out of one of the vans. An army of vampires arrive, cursing the insolent humans for their recent attack. The vampires and humans wage war. Guren walks onto the battlefield, sword in his hand. Yu is delighted, and the surviving Moon Demon Company members are shocked. Guren greets Yu and suddenly swings his sword at him. Mika intercepts it, surprising Yu. Guren tells Mika that he is in the way. Kureto announces to Guren that it is time to begin. Guren raises up his sword, and chains wrap around his arm as the curse consumes him. Mika tells Yu to run and says Guren has betrayed them. Yu disagrees. Shinoa also tells them to run since Guren is not acting like himself. After Guren wounds Yu, Mika carries him in his arms, and Krul is waiting for them. Although Yu is hurt, she says he will heal once he drinks her blood. She holds a hand out to Mika and says it is time they left. Mika glances back at the struggling Shinoa Squad and Narumi.

Yu tells Mika that Guren was crying, and they have to save him. Mika insists he is Yu's only family. Yu then violently awakens into his seraph form but now has two wings instead of only one. Krul says this is bad, and Mika asks how he can save Yu. The experiment continues, and the demon Abaddon is successfully manifested. Yu then awakens in his seraph mode. He defeats the demon and later stabs himself through the chest with his cursed gear.

Krul orders for Mika to retrieve Yu and for them to escape together. She is then confronted by Crowley Eusford, who tries to attack her from behind, but she's able to fend him off with ease. In her arrogance however, Ferid appears from behind and comments that her pretty neck is open, then promptly bites into her shoulder. She mouths for Mika to flee. Reluctantly, he does. Human soldiers chase Shinoa Squad and order them to hand over Yu. Mika appears and kills them. He says he will help, so they need to hurry and run. Shinoa orders them to flee.

Three months later, the group is near the sea, and Mika watches over some kids with Makoto. He reports that he is going to check in on Yu. Mika walks into a building and asks Yu how he is feeling. Yu is shown in his demon form with his wrists chained to a wall in a barren room with only a bowl by his foot.

Post-Nagoya Arc
Still chained to the wall, Yu reacts to Mika’s presence and demands to be released. He insists that he’ll kill all of them.

He begs Mika to remove his chains, even offering to run away with Mika and his blood. When that fails, he yells at Mika and demands he remove the chains. Mika counts to 120 seconds, and Yu's horns disappear. He mutters about turning into a demon again and greets Mika. Mika states he became a demon for two minutes longer than the day before, which he has been doing since the battle at Nagoya. Mika frets and scolds Yu for becoming something inhuman and doing irrevocable harm to himself. Shinoa states it has been exactly three hours since Yu transformed and greets them. She mentions it has been three days since Mika drank any blood, but Mika tells her he never asked her to be his keeper. Yu offers his blood, but Shinoa says Yu is too weak and has a bottle containing blood from everyone for Mika to drink instead.

Shinoa examines the chains and says the wards for sealing the demon are beginning to crack, so she and Mitsuba will have to repair them again. Mika accuses her of pretending to be Yu's friend and points out that everything that has happened to Yu has been due to an experiment. Yu says that Shinoa did not get directly involved, but Mika says he cannot trust any of them. Mika asks what Guren did to Yu.

Shinoa tells them they are not themselves when they are hungry and suggests they get breakfast. She holds the bottle of blood out to Mika, but he knocks it out of her hand. Mika appears frustrated, and Yu scolds him. Mika says he is not Shinoa's pet, but Yu says that blood belongs to their friends.

A human rushes in and addresses Sergeant Shinoa, asking for her help. The Horsemen are attacking their village. With the exception of Makoto, their group fights four Horsemen. Afterwards, Makoto arrives with food he found in a supermarket two kilometers southwest.Mika watches the villagers eat, and Yu joins him. He returns the bottle of blood to Mika, saying that Mika does not have to drink that blood and can drink his instead, but Mika says he will drink it. He says the thirst is getting worse and is worried he might drink too much of Yu's blood. Yu asks if he is okay with something besides his blood, and Mika says that at least it was not poisoned. Mika asks if this whole "being friends" thing is part of the experiments. He says they are decent for humans but wonders if it is smart to trust them.

Shinoa brings up their future plans. Mitsuba summarizes what has been going on. She says that the Japanese Imperial Demon Army will probably hunt them down and kill them, which puts the villagers at risk. They mention they cannot travel overseas because of how acidic and poisonous the blood-red oceans are. Monsters even worse than Horsemen swim in their depths.

They suggest surrendering, and Mika rejects the idea of returning Yu to the army to prevent him from becoming a demon. Makoto tells him to keep his fangy mouth shut unless he has any other options. Yu suggests meeting up with Guren, but Shinoa vetoes that idea and says they cannot trust him. Makoto tells Mika this is the circle of discussion they are stuck in and asks if he has anything to offer. Mika asks if he owes them a favor because they gave him blood, but Shinoa says no. She says that blood was for helping a friend but says she would love to hear any suggestions if he has them.

Mika says the vampire queen, his sponsor, participated in the Seraph of the End experiments. They may be able to trust her. He says she was captured and he does not know what happened to her, but rescuing her might be their least complicated option. Makoto asks if vampires are less dangerous than the Demon Army, and Mika says yes. Vampires actually care little about humans and are only concerned by power-hungry humans.

In chapter 44, with the squad's agreement to rescue Krul Tepes before Yu becomes a full demon, Yu asks about the best way to rescue to vampire queen, which Mika says Krul was captured by Ferid. Yu recalls that Ferid is the one who split the two of them up and killed the rest of their family. Yu brings up shooting Ferid in the head four years ago, but he then realizes that a gun would not kill a vampire. He mentions that Ferid is probably still alive, but Mika points out that Yu saw him back in Shinjuku. Mika asks if Yu really did not notice Ferid at all, but Yu says he was so overwhelmed to find out that Mika was still alive that he was too busy looking at Mika to see anything else.

Yu then says he hears a strange sound, to which Mika says it is a car engine, so Yoichi runs to investigate. Mika says that a human like Yu should not be able to hear that. Mika asks if the demon's possession is advancing even while Yu is awake. Yu answers that it probably is and says his senses are sharper and that he feels a little stronger. Mika is concerned that Yu is really turning into a demon, but Yu blows it off and says that he can protect everyone better if he is stronger. Mika asks what the point is if Yu loses his humanity, but Yu says Mika can hear the sound, too. Since Mika is not human, Yu says this makes them the same.

Upon Yoichi identifying Crowley and a smaller, silver-haired man, Mika assumes the silver-haired man to be Ferid. He says they captured the vampire queen. When Shinoa asks why are they coming there, Mika says he does not know but advises their group to have nothing to do with Ferid and company. As everyone runs from the village, Yu asks Mika about Ferid's strength, and Mika says he is probably the second most powerful vampire in Japan. Mika realizes Yu is thinking of something dangerous and advises him against it. He mentions going to Ferid's mansion when they were younger and says he still regrets it every day, but Yu insists it was not Mika's fault.

One chapter later, Yu and Mika observe the fight between the squad and Crowley, and the two agree that they cannot win. Mika advises escaping before they get dragged into whatever Ferid is scheming because there is nothing they can do; however, Yu wants to fight fate, explaining that because they were caught up in someone else's plot, his friends and family have died every time he ran.

Mika brings up how his planned escape attempt from Sanguinem had gotten their family killed, but Yu insists that escape gave them a future, and this time, they will be working together to make it out alive. Mika soon agrees with Yu,

Yu tells Crowley he is surrendering. Ferid then appears behind Yu and Mika and nearly drives over them. He jeers that he heard they were being attacked by a dangerous vampire, so he came to their rescue. He says he will save them if they take a ride with him, but Crowley says they already finished that part and surrendered.Ferid acts shocked and asks when Yu and Mika became so reasonable. Yu explains why they will cooperate, and Ferid asks if that means he will forget everything Ferid has done to them. When Yu agrees… Ferid pulls Akane’s head from his trunk and asks if Yu can say that to her face. Yu turns into a demon, screaming that he will kill Ferid and attacks him. Yu never comes close to hitting Ferid, but he manages to slice his fancy foreign car in half. Mika grabs Yu and tells him to calm down. Yu tells Mika to let go before he kills him. He struggles against his demon, telling it to stop while he keeps muttering about killing. Yu continues to struggle against his demon, and Mika orders him to suppress it. Yu tells him to shut up and says he just needs more power. Ferid struts toward Yu and Mika, and Mika gets between them, telling him to stay away. Ferid pulls out a filled syringe and asks if Mika will give Yu that dangerous, unstable drug instead. Mika attacks him, and Crowley intervenes, keeping Mika away from Yu.

Ferid says he is cute and bites him on the neck, drinking his blood. He then stabs Yu in the back with the needle, suppressing the demon and putting Yu to sleep. Alarmed, Mika finally leaves Crowley to returns to Yu’s side. He tells Ferid he will never forgive him. Ferid mentions that he just saved Yu’s life as Yu’s blood trickles from his mouth. Mika says they are not going to be part of his plot, and Ferid asks if this is his plot.

Mika asks him what he is trying to do, why he is here, and why he has Akane’s head with him. Ferid says he says he wanted to show them how to return Akane to life. The name of the experiment: the Seraph of the End. Once on the bus, everyone is relieved when Yu wakes up and is okay. Mika tells him they are keeping Akane out of his sight. Shinoa says Ferid claims the Seraph of the End experiment was meant to revive the dead. Mika says to not trust him. Ferid says he has the bodies of the other orphans at his mansion, but he refuses to tell them where they are headed now.

In chapter 48, the group takes a bathroom break. In the boys' bathroom, Yu rants about Guren taunting them with information but never giving them answers. They tell Yu to quit shouting. They discuss their situation and the Seraph of the End.

They decide they must betray Ferid before he betrays them. Mika tells them they are not capable of killing him. Yu mentions that Asuramaru may be able to kill Ferid if Yu lets him take control for three seconds, but Kimizuki says demons are even worse than vampires. Shinoa mentions they cannot trust a single adult still alive.

They crouch together and whisper to come up with a signal of when to attack Ferid en masse.

Osaka Arc
Back on the bus, Ferid approaches Mika and advises him to get some sleep, but Mika states vampires do not sleep. Ferid teases him and asks if Krul Tepes is the one Mika wants revenge on since she turned him into a vampire, but Mika ignores it and asks where they are going. As Ferid appears to answer, Crowley slams on the breaks and sends Ferid flying through the windshield. The group then disembarks and realizes that they are at Osaka Bay with an army of foreign vampires.

In the following chapters, while the Shinoa Squad hides out on the bus, Mika remains outside to interact with some of the vampires, including Lacus and Rene, who tell Mika their plan to retake Sanguinem. When Ferid and Krul's punishments begin, Mika walks away while the other vampires continue to watch. He asks Yu what they should do now, and goes with Yu's plan to rescue Krul and Ferid. Crowley takes the Shinoa Squad to Ferid's mansion in Osaka. Mika asks if Yu is okay, and Yu admits to feeling queasy. Yu says this place looks similar to the one in Sanguinem. Recalling how Mika gave Ferid his blood when they were growing up in Sanguinem, Yu says he should have been the one to give Ferid blood instead of Mika. Mika asks if he would rather Mika be the half-demon instead. Yu says no, and Mika says the two of them are even by now.

Mika asks Yu if he is sure he wants to save Ferid and asks if he can forgive him. Yu says Ferid could bring Akane back to life, but Mika reminds him that Ferid cannot be trusted. He says that if Guren really brought his squad back to life, then the experiment results in the destruction of the world. Mika asks what the price would be if they brought Akane back this time. He advises Yu to not be greedy and want more than what he already has, or else Yu may become a demon like Guren Ichinose.

Narumi points out that Yu is already a demon because he felt guilty about Mika becoming a vampire. Yu tells him to not pick on Mika. Narumi says Mika is not arguing with Yu from an honest stance and says that the only thing on his mind is convincing Yu to escape with him. Mika says that escaping is sometimes the better part of valor and warns them about Ferid once again.

Mika says that the dead should not be brought back to life, and the experiments he has seen are horrible.

While Mika says that greed will only lead to despair, Narumi says it will lead to hope. He says this determination is what allowed humanity to grow as strong as it has. They end their spat with Mika telling Narumi to stop being stupid, Narumi telling Mika to not be blind, and Shinoa and Yoichi stepping up to them and telling them that topic is closed.

Mika apologizes and says he was just feeling uneasy. He cannot stand the thought of losing friends again because he was not smart enough to see what was coming.

Mika warns Narumi that he will be easy for Ferid to manipulate in this place in more ways than one, and Narumi says he will keep that in mind. Moments later, vampire Tenth Progenitor Fuola Honte comes out of the mansion and attacks the squad upon sight. When fighting Fuola, Mika is questioned by the progenitor on why he is with the humans before cutting off Mika's lower arm. Yu goes in to help him and Mika warns him not to come close, but Yu is able to intercept Fuola's blow. Shinoa then uses Shikama Dōji to pull him and Yu back while Mitsuba uses Tenjiryū to retrieve Mika's arm. Fuola then tells the Shinoa Squad that he has no time to fight them as he is running from a monster which turns out to be Crowley. They watch as Crowley overpowers the Tenth Progenitor and comment on his strength. Crowley challenges the teens to fight him and they lose easily.

Crowley reveals he is really a Seventh progenitor and hid his strength under the guise of a thirteenth. He claims Ferid used a second progenitor's blood to turn Crowley. Mika comments that that proves Ferid cannot be trusted but Yu says that they already agreed to rescue him. Shinoa Squad wonders how they will beat a Fifth if they cannot beat a Seventh.

Yu gets mad at Crowley for not telling him that he too used to be human and Shinoa Squad wonders how he can be so calm around another vampire. Mika says it's because he is dumb and Kimizuki says they never thought of vampires as former humans. They all agree that vampires are raising human as livestock so humans naturally fear vampires. Narumi questions if predator and prey can really live together and Mika believes that Narumi dislikes him.

Narumi muses that there likely has not been a newborn vampire in a century, yet Mika is a rare newborn. Narumi cuts himself and questions how long Mika will see Yu as his family. He asks Mika if vampires like Ferid and Crowley still retain some humanity as Mika struggles against the urge to drink blood.

Narumi once again questions Mika's humanity and Mika says his humanity has been vanishing since he first drank Yu's blood. Mika says he can feel his emotions weakening, and because of this he does not trust Ferid or Crowley. Mika's anger towards Ferid for killing his family is also fading, yet his feelings for Yu have not changed at all. Narumi decides that means vampires can cling to a fragment of their humanity, and so alliances are possible. Shinoa Squad enters the mansion and Yu realizes it is time for Mika to drink blood but Mika stops him, and follows them to the kitchen to eat. While everyone is messing around, Mika asks Crowley how much time he has before his emotions completely fade. Cut to some time later when everyone is done eating, and Mika is seen in a new outfit sitting in front of a glass of blood.

Yu comes up to check on him and offers his blood in which Mika says he will drink later. Later, when Yu takes Akane's head to keep calm when entering the basement, Yu promise her that he will bring her back to life which Mika warns him that it's either impossible or will end up destroying the world and wants to keep Yu safe. Yu responds that he cares nothing about the world and is willing to destroy it to return Mika human, and bring back the rest of the children, Narumi's family, Mirai, and everyone. Down in the basement, Yu tears up upon seeing Taichi's body, so Mika holds Yu's hand for comfort. Later on, everyone hears a noise outside the mansion, with Guren coming down the stairs some time later. Mika hangs back while most of the squad goes up to him. He along with everyone else listen to Guren's revelation that the Hīragis and the Demon Army are being used by someone else.

After listening to Guren's explanation, Mika decides to kill him as he sees Guren as a bad influence on Yu, while also acknowledging that Yu would hate him for it. Upon Guren calling out Mika's desire to kill him and Yu covering for him, Mika cuts Yu off with an apology to him before clashing swords with Guren. When Yu tires to get Mika to stop, the blonde asks why Yu is defending Guren, which Yu answers that he is family. This shocks Mika, and leads him to slash his sword down at Yu's side without touching him. Before he could continue though, Yoichi asks if they could talk this out as he and Kimizuki stand by Guren's side with their weapons drawn. Mika asks why they are interfering, but upon Yu calling out to him, he ends his attack and demands to know why everyone is so happy to see Guren for all the deeds he has committed, even pointing out Yu sounding like he is brainwashed. When Guren apologizes, Mika tells him to never come near Yu again, which causes Yu to yell at him. Upon hearing Makoto's conclusion that the catastrophe would likely have happened even if Guren hadn't resurrected his friends, Mika calls the conclusion semantics, and was against everyone wanting to know Guren's agenda. When Guren reveals that he seeks to resurrect everyone that was killed by the virus eight years ago, Mika questions this plan, and learns that only those that have died by the apocalypse virus eight years ago would be revived. Hence, Akane and the Hyakuya orphans, who were killed four years ago by Ferid, could not be revived. Guren points to the spell tomes that can better explain this resurrection ceremony in response to the squad members points and questions relating to that qualifier, and tells everyone that they are going to have to trust him, but Mika still sees this plan as a con. Guren tells him he could leave, but when it turns out that Yu is needed for the plan and Yu agrees to help Guren, Mika tries to talk Yu out of doing this, as he fears being separated from him again, to no success and ends up agreeing to be there for Yu. Later on, Mika overhears Yu and Guren talk about the former getting stronger by becoming and controlling the seraph despite the risks it would have on Yu's heart and body. The blond makes himself known when Yu tries to keep this a secret from him, saying he sees no point for Yu doing this after knowing the risks. Mika learns from Guren Yu will be using medicaments for this training, and became annoyed at Guren's response about the side effects of the medicament that he asked Yu if he could rip Guren's head off. He follows the two outside in the courtyard and watches as Yu injects himself with the drug to begin his training to control the seraph.

Three days later, Mika listens to Guren's review of the plan to rescue Ferid and Krul from Ky Luc, where he will act as a decoy with the rest of the squads and Crowley so that Yu can kill the fifth progenitor as the seraph. The group was able to save Ferid in the end while Ky was able to get away with Krul, so Mika goes over to check on Yu followed by Shinoa squad. Later on, Mika goes with everyone to Guren's home in Nagoya so that Yu can recover in the basement. Mika waits outside the container Yu is in, and Yu soon awakens after four days. Mika tells him that he collapsed and his heart stopped, but Guren saved him. Mika says that he still doesn't trust Guren due to everything he's done, and still shows disapproval of Yu turning into the seraph. The two walk through the basement that was used as the place for human experimentation, and Mika questions Yu on Guren still being a good guy for experimenting on their family.

When Mika and Yu go outside, he hears Yu's words that he will return all the children. Mika hesitates a little at first, but then shakes Yu's hand. Guren approaches the two of them and the three go to the basement. Guren asks who they are, since the names of both of them are Hyakuya. He shows Mika and Yu another seraph. Yu tells Mika that they will go to him together, but Mika is pushed away by the barrier. Mika starts asking Guren what he is doing, but Guren asks him who he is. Mika remembers how Saitō brought him and the others to the orphanage. He asks Guren if he knows Saitō, but Ferid appears and interrupts them. Later, Ferid says that among them there is another seraph and points to Mika. He asks if Mika is Saitō's new angel, but Mika cannot answer who he is. Later, Mika, together with a squad, fights against 6th trumpet. After defeating him, Mika picks up the sinful key, but Ferid demands to give it back. When Mika refuses, Ferid teases him.

Shibuya Arc
After that, he and the others travel to Shibuya. He joins Yu on the roof of the car and says that he himself does not know why he went with everyone, calling himself an idiot. When the squad wants to join them, Mika is not happy, although Yu says otherwise. He later drinks Yu's blood from his hand and blushes as they come to Shibuya. When Yu senses that there are enemies nearby, Mika fights alongside him. They enter the building together. Mika asks Shinoa about who she is, and then, after Shinoa leaves, says that the place is incredibly dangerous. They go to Yu's room and Mika notices that it is empty. He hears that Yu was only thinking about revenge. He tells Yu that the vampire's heart is not beating and Yu puts his hand on Mika's chest to listen to this. Mika again hears Yu talking about the resurrection of Akane and the children, and asks if the end justifies the means, but Yu replies positively. Mika agrees to Yu's plan and they attack the soldiers. Tied up, Mika and Yu are brought to Kureto. Mika does not want to speak out loud about Yu's plans and is ashamed of his behavior. He later joins everyone when Shinoa begins to become a vampire. With Shinoa taken away to try and stop her from transforming into a vampire, Mika is nearby as Yu shares details on what he knows of Shikama Dōji. Mika taps Yu from behind and advises him not to hand out information like that for free to Kureto. He tugs Yu’s clothing as Yu continues to openly divulge information with Shinoa’s safety at stake, to no avail. As Yu continues to spill that he and Asuramaru do not remember anything, Mika shouts his name as Yu offers himself up for examination if the memories can help save Shinoa. Mika remains calm and does not outwardly react as Yu is taken by Kureto’s men being robbed of his freedom and declared their experiment. Taking a moment to consider his options he watches Yu being taken away and assesses his course: to abandon Shinoa and save Yu, or another option. Head bowed in thought, Mika trails behind Yu as he is escorted away. He contemplates that it is hard to believe but somehow Yu has memories of the first. He pauses to look to the side finding it incredible that the first has awoken so many times and even though he has not met him he can somehow tell that he is the source of the curse that made him into a vampire and concludes it’s a monster. Distracted further, he realizes that Ferid may have just went down, bad since it means the first could fully awake. With that Mika reasons Shinoa Hīragi is a lost cause, worse that with the entire Hīragi family having been possessed by the first for centuries, Mika considers it possible that they have all been deliberately led here, and that everyone present may in fact be the first’s puppet. With what has happened and may happen it is more dire than even Mika thought and his consideration is to get Yu and get out of this place. His plans are disturbed as Mika is tapped on the shoulder by Guren’s sword. He makes the excuse that he is going to the bathroom, and that he won’t let another puppet of the first use Yu when Guren says he is not taking him. Mika does not believe that Guren is trying to help Yu, saying he knows exactly what type of man Guren is. Not replying to his question of where he could go, Mika thinks he has a point and is not sure that he can get Yu away from the first for good. He asks if he wants Guren to trust him and motions that he should before suddenly drawing his sword swinging it into Gurens. Mika does not care that he is alone, he evades Shinya who tries to ambush him from behind with his rifle before being floored and disarmed by Kureto’s extensive lightning attack. On the ground, Mika says it isn’t fair before hearing that without Yu, he has no allies and being alone makes him an easy picking. He cannot join them when Guren offers, not believing they are not puppets. Mika listens to them arrange battle plans for the first before noticing Ferid. He and the others are told to run as Shinoa joins and attacks them all with many scythes. With Shibuya under attack by the Hyakuya Sect, Mika runs alone through the streets before looking up to see explosions and a whirling halo of scythes near the top of a building. Wondering what is going on, he then dismisses it as a concern deciding he has to find Yu first. He tells himself to concentrate, hone his senses and search for him. Blinking, through some means Mika succeeds in locating Yu and leaps across apartment blocks towards him. In his search he wonders where Yu is, and arriving on top of a building he finds him restrained and being transported below. At that point, Mika whirls around and asks what was that. Returning his attention to Yu, Mika watches and considers how he can save him from the guards around. He does not react well to seeing Guren there even after he dispatched Yu's kidnappers. Observing, he wonders that is the correct answer and course of action here. Witnessing Guren bind Yu's mouth results in Mika stating that he knew he was the enemy, but considers whether he has the power to save Yu. Glancing round to see who has answered his question for him, Mika swings his sword into Mahiru's upon being found by her. Asking who he is, he does not respond to her assertion that she is everybody's favorite lovely idol. Evading her attack, Mika notes she is too slow and he can beat her. His sword misses to his distress, before he finds and dodges Mahiru's strike near his neck. Mika is then subject to multiple spell tag explosions and whilst he can just about avoid them, there is no time for any counter moves. Jumping off the building, he leaves this battle, forgets her and resolves to save Yu. Slicing through Yu's bindings, Mika frees and calls to him standing beside Yu battle ready. With Noya and Guren as a demon opposite him, Mika wonders if he and Yu can even get away from this. Whilst not certain, he replies to Yu that he knows the situation is really bad and to stay on his toes. Stern, Mika incredulously seizes Yu demanding to know in what world did what they just saw make Guren look anything like an ally. Changing tactics, Mika happily praises Yu as being absolutely right that Guren has always been on their side. Explaining that Guren let his demon possess him in order to protect them, he is now in big trouble. Mika invents a perfect foolproof plan that involves running away to meet up with the others.

Aware that Noya has conjured two spectral katanas, Mika's plan to run is interfered with the arrival of Mahiru and he warns Yu not to listen to her since she is trouble. Checking Yu when he appears pained by memories, Mika tries to convince him that Mahiru is tricking him. Mika smiles after Yu takes his arm and announces him as his reason to live. After holding his arm in turn, Mika defends from Guren's sword strike. With some difficulty in blocking it, the impact sweeps him off his feet and he calls to Yu to stay close, that they cannot be separated. Mika takes Yu's hand in time to ensure that they both crash land in the same vicinity. Asking if Yu can stand, Mika decides they need to run now. He is remembered by Noya before Mika is running away from this foe. Aware at their speed that they will be caught, he thinks to find a place to hide. With the first scenario occurring, Mika uses himself to shield Yu from Guren's sword. Struck across his back, Mika shouts for Yu to jump backwards as hard as he can and is taken with Yu as he escapes through the other side of a building.

Carried in Yu's arms with his back in a great deal of pain from the cursed gear, Mika tells Yu to forget about the wound healing and hide since if Guren catches them he will kill them. Bleeding, he voices to Yu that it is bad and he is gasping for blood. Feeling if he can drink some he could get some strength back, Mika complies with Yu's suggestion to drink whilst Yu continues searching for a hiding place. Mika likes Yu's blood so much that he has to be pushed off yet they have made their way to the inside of a building. Replying that Yu's blood tastes dangerously good, Mika says he is sorry for drinking to that extent. His back has healed though he is concerned about Yu feeling drained. Wary of Yu drawing on demon power, Mika watches as Yu does that out of necessity then witnesses Yu turn into a demon. Concerned whilst watching Yu scream, Mika bafflingly asks whether he realizes that he just grew horns. Asking if he is okay, Mika questions whether he is going to go berserk. Appearing panicked when Yu falls over in his demonic rage and clutching his head, Mika then remarks on Yu vanishing where with his speed he could not even see where he went. Mika finds him, in the ceiling with just his legs poking though.

Checking if he can communicate, Mika urgently thinks how they can escape with Yu in his demonic state. Feeling it is impossible, Mika tries to pull Yu out. Hearing a crash, Mika sees that Guren has caught up to them already. Stating they have to go now, Mika thinks Guren is not wrong that he does not stand a chance of getting himself and Yu away from him, and turns to Yu that he said he would run away with him. Keeping an eye on them, Mika sees Noya return to Guren's sword and says to Yu for them to get out of here. Finding he is gone from the ceiling, Mika is pulled up to the next floor by Yu. Addressed as "Michaela", he questions the person before him who he is. Hearing that half is in control, Mika asks who is speaking and hears it is Ashera Tepes and connects the surname as he thinks of Krul Tepes when he was a child.

With Guren smashing through a wall near them, Mika queries whether he can trust that Ashera is helping Yu. He is visualized as a child in Sanguinem with Yu as he is called family, and presently smiles warmly. Feeling that matters are looking up, Mika thinks with himself and Yu he is sure they can pull this off as he orders his sword to drink deep. Beside Yu, he faces Guren sword drawn. Ready Mika asks if Yu got him after he fired a heavy attack on Guren. A spell tag that Yu's attack connected with rips and Mika asks where Guren went before having a spell tag placed on his shoulder by him. Reacting to the binding energy, Mika shouts that they have not lost yet. Ordering his sword to spit his blood out, Mika then uses his hand to stop a needle from being stabbed into Yu's neck. Shouting for Yu as he is stabbed by Mahiru-no-Yo, and then hit with the syringe, Mika considers how resisting is not working. Seeing Yu's consciousness is back, Mika makes use of biting and draining Guren of his blood. Willing him to die, Mika is struck in the head with the hilt of Guren's sword and hurled into the wall. Incandescent, Mika has his sword drink more, if he is going to kill Guren he requires more power. With thorn branches wrapping around him, Mika wants his weapon to suck up every last drop of his life and spit it back into Guren's face. With thorns encircling him, Mika thinks Guren is much to dangerous to Yu and he has to kill Guren here and now. Looking to Yu, he says for him not to worry, that he will keep him safe. Slashed across the chest, Mika's sacrifice sends a large sweeping arc strong enough to rip the tops of buildings off. He has been cut where his upper torso falls below and Mika is held by Yu on the ground. At first unresponsive, markings appear on Mika's face as he struggles to speak. With with his wound seeping a heavy amount of blood, Mika has expended too much of it. He is continued to be held by Yu as Krul arrives before shouting out as an increasingly amount of shadowy strands float out from him, and Mika rises into the air. Mika's life force has vanished and his declaration to keep Yu safe is remembered by Asuramaru, as well as his time as a child by Yu. Ascending vertically, Mika is able to discern Yu and asks him not to cry. He can see Shinoa and Mitsuba some distance away and knows that Yu will be fine. Mika closes his eyes and tells Yu that he loves him, before an explosion occurs.

Post-Shibuya Arc
It is recalled that when Mika went to bite Guren he had a substance injected into his hand. In the midst of the explosion there is an black flat oval shape where Mika's face should be. A beating sound is heard and and a right handed arm reaches through the portal on Mika's face. This is vampire Mika having died who is now transforming into a black demon according to Guren.

Mika is his child self in casual clothing and sat within a field that has flowers around and a cloudy sky above. After being unresponsive with his eyes open Mika wonders where he is. Told he was drooling by young Yu next to him, Mika asks whether he was sleeping. Mika hears they were up late last night playing Othello together. Puzzled by Yu mentioning going home and the kids, Mika observes Akane with children playing nearby. He picks up on Akane mentioning demons. Feeling weird, for a second Mika had the feeling that he a super-awful nightmare. Thinking if all the terrible things that happened were a nightmare, Mika fondly details his nightmare as he takes Yu's hands. Saying there were monsters everywhere, Mika jokes they were more like ghosts. Describing it as the scariest nightmare ever, Mika tells Yu not to worry, he will make sure to wet Yu's bed not his before laughing. Calling to the others Mika says it is time to go home, they are having curry for dinner tonight. Mika corrects Yu's claim that he made it by replying Yu just cut the potatoes. Hearing from Akane that he was asleep for what had to be two hours, Mika questions Yu whether he was really asleep for that long and appears unsure. This is replaced with contentment as he sees his family walking back together. Mika can hardly believe this and thinks he is so unbelievably happy right now. Everyone is here and Mika notes Yu specifically is here. Serving food, Mika joins Yu in saying thanks for it. As he eats Mika wonders how is this even possible, he can barely process how happy it all makes him. Mika has a question for Yu, namely what happened to the director again. With the Yu sat next to him puzzled by the question it dawns on Mika and as he thought so it was too good to be true. Continuing to eat anyway, Mika replies nothing is wrong and he is fine. With a child wanting to play cards after dinner Mika listens as Yu explains that they are going to bed early tonight since he and Mika were playing Othello late last night. When bathing then brushing their teeth Mika looks to Yu and whilst happy Mika thinks of what all of it is. As the family sleeps Mika lays in his futon staring upwards. Once Yu enters the room Mika asks is this not the greatest. Everyone is here and for all Yu's complaints on how tiring he finds it Mika tells him he does look after everyone really well. He is way different than when they first met and Mika continues by making a face to illustrate what Yu looked like back then. Mika teases how Yu thought he was a demon who cannot be anyone's friend and not be family with anybody, that he was crying and whining all the time. Yet now Mika feels Yu is like the mom of their whole family. With Yu questioning why he has to be the mom, Mika questions he wants to be the dad instead and adds "hi, papa!" At any rate Mika continues that it is the greatest ever that they are all together with everyone alive and healthy. Concerning Yu, Mika fondly mentions him here too still complaining and saying all the stupidest things. The matter turns to them being together, smiling every day and growing up. Soon they will be fifteen then twenty and whilst some of them may go their separate ways Mika and Yu will always stick together. Eventually they will turn thirty and Mika says by the time they are a hundred they will probably be dead but focuses on them being able to look back. Mika asks if they can say they had a full life being considerate to everybody then would that not be a nice way to go. Checking if Yu thinks that, Mika replies that nothing has gotten into him it is just that he was thinking how really happy he is that Mika could cry. Asking whether Yu means it when he voices the same, Mika listens as Yu explains Mika as a source of his happiness and reacts as if he is regarding the heartfelt shared feelings as feigned insincerity. Questioning what will come true when Yu says it, hearing that they will turn two hundred Mika replies that are not going to live that long, they are only human. He is skeptical of Yu's claim that if them being together is his greatest happiness then it will come true. After Yu affirms that he will make them stay just like this for even longer, Mika points out that if they cannot live for a hundred years then they definitely not living a thousand. Commenting that stupid Yu strikes again after he suggests that it can be done with a thousand push-ups every day, Mika says he cannot solve everything with that. Mika's hands are taken by Yu and he is told he does not have to be scared anymore. Told that Yu is here and always will be, Mika asks if he is not going to leave him and whether nobody will die. With Yu eagerly asking Mika to want to be here forever, Mika says he does not have to tell him that is his greatest desire. Mika knows this is what he wants most from the bottom of his heart. Tearfully, Mika blurts out that this is a dream. Questioning how Yu is going to make it true, Mika shouts how when everyone died. Saying he could not protect them, Mika states he even left Yu himself behind right when he was on the verge of becoming a demon. Mika feels he failed, took weak and useless where he could not save anyone. Hugged by him, Mika hears how Yu will always be here so he will be fine. Saying he is tired Mika listens as Yu explains they can be together forever. That is possible here. As a black mold like substance spreads over Mika's pajama top from Yu's hands that are holding his waist, Mika hears from the speaker if he really does want to stay he could choose to become a demon who devours human desires. Mika is silent as six seraph like wings appear from his back.

Within the sky the electrical shadowy mass around Mika has blotted out the sun. As the arm continues to reach out of his mouth, another one joins it. A hand directs itself but Mika does not react to Yu calling him yet the hand continues to reach for Yu as Krul takes him away and a great cry is emitted. From his mouth a child with horns emerges. Standing near a winding shimmering road a demon who resembles Mika in a black cloak comments how this world is so bright. Thirsty and with his right arm disappearing the demon knows it must find a human they can possess and devour their desires.

At some point in the illusionary world Mika comments to Yu how everyone is finally asleep then happily replies how he is beat. He questions if 'Yu' is not tired at all then answers that he is a little hungry before agreeing to cup noodles time. Mika and the Yu he is with are observed by a separate entity, the demon resembling him. Whilst eating with the Yu he laughs unaware that demon Mika is stood behind him. Mika is happy laughing with Yu before expressing shock at Asuramaru suddenly thudding into their home. After asking who he is is, Mika watches nervously as he hears that Asuramaru intends to murder his family then rip their hearts to shreds.

In response to Asuramaru he shouts for Yu to run and pushes him out of the room before telling him to get the kids outside. With his attention on Asuramaru he retrieves a kitchen knife and charges to stab him in the chest. Pushing Asuramaru over, Mika then stabs him repeatedly and calls for him to die. Hearing that his fear can be seen, Mika orders the monster to shut up. Mika is visualized amongst his deceased family with Yu holding Akane as Asuramaru speaks that his deepest fear is that he is too weak to protect his family.

No longer stabbing Asuramaru, he is greatly agitated at the allegation and falls backwards. Mika asks if he did kill them and whether they are dead because of him. Hearing that his deepest desire is to have someone blame him for that, Mika is told that this shall be re-created where he shall kill his family again here and now. With his arms taken, Mika is walked along the corridor by Asuramaru as he says for him to stop. As he is informed that these last eight years he has desperately wanted to excoriate himself as the one who killed his family, Mika tearfully orders Asuramaru to stop.

A shadow of Mika with horns is seen before Mika himself finds his family as he holds the knife. Told once again he is going to kill them with his own hands, Mika's hand raises the knife. Absolutely certain that he does not want to kill them, Mika asks for someone to please save him and calls for Yu.

The children lay still as Mika stabs into someone. He then turns to Yu and plunges the knife into his chest. Once Yu says that Mika did it, he agrees that it is his fault. Saying sorry, Mika states that he always fails and can never save anyone. In the physical world, Mika's sword is in the centre of a now activated spell circle. It is gripped by Yu which allows him to enter the world where Mika is.

When Yu has fended off Asuramaru, who with Kiseki-o and Gekkouin were attacking Demon Mika, he awakens in a version of Nagoya with a red sky where Mika found Yu again and first drank his blood. It is recalled how Mika embraced Yu before becoming a complete vampire. Mika's sword is used by Demon Mika who Yu sees as him.

Appearing as a human teenager, Mika is walking on a circle of light with light particles floating down upon him. He is wearing a T-shirt and trousers. Regarding his hand and saying 'what' Mika asks aloud where he is and what is this place to Yu. Looking up, Mika registers a single large eye staring down at him. Asking what in the world is it, Mika feels it is weird in that the eye seems kind. Addressing it, Mika questions on how he seems to it, that it does not see him as an enemy. Approaching and asking what the eye is to Yu, he wonders why it is inside of him. Saying that he is going to touch it, Mika wants to look inside. Asking if the eye is ready, Mika's hand shimmers as he reaches towards it.

Observing a room with a clear box in the centre, surrounded by fluid filled, glass like storage tanks, Mika finds he cannot move. Wondering where he is and what is this room, Mika sees dozens of what he calls that weird eyeball and considers is that machine making them. With Yu entering the room, Mika notes he looks like a child. Observing Yu interact with a vampire with long hair and another vampire, he is surprised to see one of the eyeballs be formed into a whole new child Yu. Registering the eye that he is in, Mika can view its perspective, but does not appear to have anything to hear the conversation taking place. The eye Mika is seeing from is turned into Yu. Regarding a hand that the Yu he is in is looking at, and realizing it is Yu's hand, Mika comprehends right now he is Yu.

The Yu he is in does not speak so is not killed, and with the viewpoint kept, Mika wonders what the hell is this. Questions are when is this memory from, and who these two are. Mika then sees an entourage of demons enter the room, with Raimeiki and Byakkomaru speaking. Observing and wondering who are they, with Kiseki-o and Raimeiki there as well, Mika feels they seem strangely familiar. On Sika Madu in the middle, Mika knows he is bad news. Finding that he can be seen by Sika Madu, and shocked by this, Mika shouts he has to wake up now and needs to get out of here.

As a child in the place of Yu, Mika falls first to the ground, then finds he is falling away. Aware that he is being spoken to, Mika calls for Yu. Hearing if they work together they can get away, Mika focuses on Yu and resists Sika Madu's efforts to have him sleep. Hearing Yu speaking that he will devour him, and Mika will devour Yu, that will let Mika become Yu's demon. With Sika Madu shouting for him to sleep, Mika speaks he will become Yu's demon. Under an electrical based pressure, Mika finds he cannot stay awake. While he does react to Yu's voice he apparently does not know that a human child form of him is being observed sleeping by the First, and does not respond to Kimizuki and Yoichi's arrival. Having spent time as a child demon without any memories, demon Mika made a contract to become Yu's demon and assumed a teenage demon form of himself where they fended off Sika Madu. During this fight, demon Mika devoured a ton of Yu's desires for strength where a lot of memories were eaten too. The memory of himself pushing Yu to escape from Sanguinem is remembered. Being a demon, Mika can access Yu's memories and feelings, as well as his own now. Recalling that he felt it was his fault this happened, Mika wanted Yu to escape. Reacting to this, Mika finds his memories returned, where he is no longer a demon acting as a demon does, but himself as a demon.

Sharing that it is like memories in stereo, Mika says his has Yu's memories as well as his own. Considering how he really does have both, Mika checks a memory of Yu as a child training with Guren. He looks to Yu who is speaking with Yoichi and Kimizuki. Thinking how all those years Yu suffered, feeling alone and abandoned, Mika ascertains his savior was Guren Ichinose. Seeing that is what he means to Yu, now that he has eaten his memories, Mika gets why he trusts Guren so much but wonders whether trusting him is wise.

Asked if he can manifest outside, Mika answers probably. With Yu meaning for them to head back as everyone is waiting for them, Mika has something to say. Honestly stating how he is kind of mad at him, Mika raises how after Yu left Sanguinem he tried to die a bunch of times. Having indeed peeked into his memories, Mika affirms what Yu did is totally unacceptable. If Yu had died, Mika questions what would have been the point of him throwing his life away to save him. Getting that Yu did not find it easy, Mika says to still not do that. When Yu is happy everything worked out, Mika raises how it was because of Guren.

While Mika guesses he will have to thank Guren as now both he and Yu found each other again, inwardly, Mika bets Guren has an ulterior motive for the rescue. Considering Guren and Mahiru, he feels it would not be done out of the goodness of his heart. Also regarding the angels and what is up with them, Mika further thinks what were those monster blob things that he could see as a demon in Yu's memory.

Speculating that the answers are probably somewhere in Yu's memories, Mika guesses sometime soon the two of them are going to have to go digging through them. Walking beside Yu then promising he will protect him, Mika extends his hand to Yu's. In the physical world where Mika's sword is, he materializes as a demon before members of the team. When Yu thanks Shinoa for helping to save him, Mika considers the display. After Guren announces it is good they are back, Mika glares at him, silently.

Stood looking upwards at the sun, Mika feels it is so strange. Thinking how he is out in the sun, Mika finds he can also look right at it. Engrossed, Mika then registers that he was just addressed as "Mika-poo" by Yu. Responding with what the heck, after being asked what he is thinking of, Mikas answers nothing, he just realized he could look at the sun. When Yu tries the same and reacts to the brightness, Mika orders him to not look directly at it.

When Yu discusses how when Mika was a vampire he could not look at the sun, but now as a demon he can, Mika guesses that it probably what it is. Speaking how more and more of his memories as a vampire are coming back, in response to Yu asking did he not get them all back at once, Mika clarifies how he got some of Yu's memories after he devoured some of his desires. From that, Mika got his memories and some of Yu's memories, but they are all muddled together in this big mess inside his head. Explaining that if he does not concentrate and single out a specific memory, Mika finds it is really hard for him to tell what's what.

Asked if he can read Yu's mind now, Mika considers the question before feeling probably, if he concentrated. After mentioning that Yu's desires are his food after all, Mika is asked to say what Yu is thinking right now, and agrees to look at his thoughts. Looking ahead, Mika can see a corridor and can view a memory concerning Yu and himself on either side of a closed door. After witnessing the toilet related memory of them as children, Mika asks Yu what did he just show him.

Where Yu is thrilled that he really can see into his head, Mika details he is not 'seeing' so much as he is eating Yu's desires and they come along with it, even when they are dumb crappy desires like that one. Mika is not pleased when Yu responds that technically he was the one taking a crap. While Yu is eager to try another memory, Mika does not want to see any more dumb memories. Assured this memory is awesome, Mika agrees to try but can only make out static. Sharing that he cannot see anything, Mika hears it is the same with Asuramaru, where nothing can be seen if Yu makes the walls around his heart really high. Getting it, Mika sees so that is how it works.

As Yu details further how when he wants power Mika is given desire which connects them, Mika continues because of that he can see everything. When Yu speaks how if he overdid it with Asuramaru then he risked possession, Mika states at once he will not possess Yu. While Yu does not care, Mika is firm he is still not doing it. Paying attention to Yu saying that they can work together on a whole new level now, and they should try stuff and figure out what way works best, Mika appears satisfied with that. Telling Yu it is a fair point, Mika adds for once he is actually taking things seriously, yet is not so certain of Yu's words that he is a grown-up now and all.

Observing Yu tend to Shinoa who ingested poison, Mika considers how Yu's friends saved him, and Guren Ichinose helped too. Heading over to place his hand over Yu, and thinking to himself, Mika wonders how did Yu meet Guren. Whatever his plan is, Mika imagines it is big, and one that has been in the works for years. Even if he asked him, Mika doubts he would tell him. Glancing over to Guren who is with Mahiru nearby, Mika wonders why he is doing this.

Accessing the memory of when Yu as a child escaped Sanguinem and met Guren who was with Sayuri and Shigure, standing within the scenario, Mika observes it with the addition of many black suns floating in the sky. Focusing on the matter of that day, that time, and place, Mika reflects on how Guren was waiting for Yu, so wonders who let him know he was coming. Speaking to go a little farther back, Mika stands in the memory of Yu about to shoot Ferid within the exit hall of the city.

Placing his hand over the memory of Yu as a child after saying his name, Mika then glares at the memory of Ferid. Looking back now, Mika can tell that Ferid could have easily dodged that. Contemplating Ferid's actions and fearful appearing face, Mika sees this was all an act. Staring intently, Mika ponders why, and how is Ferid connected to Guren.

Speaking to move forward, all the way up to his memories, Mika faces the scenario of Krul talking to himself as a child after he had been seriously injured. Listing Guren, Ferid, and Krul, and noting how they were in the same place at the same time, Mika contemplates further how for some reason they got involved with himself and Yu. Thinking why, Mika wonders whose plan is this. Talking to the memory of Krul, he asks if it is hers, before thinking or someone else's. Considering whether he has missed something, Mika wonders is there some other clue buried somewhere in his memories.

His attention drawn to the shadows in the Sanguinem exit hall, Mika finds Mahiru standing near the wall. Registering her prescence and questioning whether she was there too, Mika notes where she is looking and remarks it is like she is staring right at him. Judging this place a nightmare, Mika comments they are surrounded by too many crafty bastards and wonders if he will be able to protect Yu.

Hearing his name spoken, where a hand is in front of his face, Mika finds he has been physically tapped away by Krul. Sent away by the impact behind it, from his place on the ground, Mika questions if Krul had to do that. While Krul professes it is good to see him well, she intends to check how powerful he has become, and Mika engages in a brief physical clash with her.

On the ground again, Mika asks Krul what she is getting at when told she is still more powerful than him. Praised for surviving the First with the level of his strength he had, Mika questions if that was supposed to somehow count as a compliment. Informed it was since he is of her clan, Mika addresses that and asks does that mean Krul loves him. Asserting that if she did love him, then to tell him something with no secrets, Mika questions what Krul really wants. Hearing it is her brother Ashera, he speaks the name Asuramaru when told that is what he knows him as.

Turning to an incoming truck, Mika stands near Mitsuba and Yoichi as they are ordered by Guren to get in the vehicle with Ferid who has found them. Destined to move to a location where no one can touch them, when guided to relax by Guren, he thinks that is not happening. Collecting his thoughts that all the shadow players are coming together, Mika takes his place by Yu while thinking he has to be there to protect him.

Having noticed Shinoa behind him, Mika listens as he is cautioned to not trust anyone, stay wary and protect Yu. Additionally, Mika is warned to be careful of her sister, with Shinoa remarking that she is dangerous. Realizing that Mahiru has approached, Mika is asked whether he has seen her in the past. Questioned if he can see memories from before this Yu was born, Mika asks who Mahiru is. Along with Yu, how many tens of thousands of years Mika has lived is going to be figured out.

In the back of a truck being driven by Ferid, as Yu interacts with others, Mika sits observing before reacting to something he can sense. Regarding Krul, with Guren and Mahiru before him, after being grinned at by Mahiru he speaks Yu's name. Changing to thinking of his name as he moves to communing with him in their sphere, ahead in a cloudy like landscape Mika sees Yu then shouts for him to answer.

Asked what is wrong, Mika raises what is he doing, where now is not the time to be having a fun chat with friends. Questioned if he wants to join in too, Mika frustratingly responds that is not it. Addressing whether Yu even realizes the situation they are in, where they are going to Ferid's place, Mika questions Yu what they are to do there. With Yu not knowing, Mika says for him to think before he details how Guren, Mahiru, Ferid, and Krul are in cahoots and have been for years. Explaining when Guren rescued Yu, he did it for a reason, Mika then shares that they have some kind of grand plan and they are taking advantage of them to make it work. Before they let themselves be used, Mika says to Yu they need to investigate and find out what that plan is.

With Yu seemingly understanding, Mika addresses the good plan Yu mentioned he had. Asking what it is, Mika is told to wait and see. Returning to be conscious in the back of the truck, Mika considers the conversation Yu has commenced with Guren. After Yu bluntly asks Guren upfront what this plan plan he has in the works is, Mika appears exasperated while raising how Yu is just going to ask flat out. Listening as Yu speaks how he is grateful to Guren, Mika stares in the latter's direction as the conversation continues. Mika reacts when Guren confirms Yu's question that he is using him.

When Guren falters after being asked if he was involved in Ferid's action of murdering his and Yu's family, Mika is called for power where the intent is to destroy the truck they are on and leave. Calling Yu's name, Mika complies at once by placing his hand on the ground to emit electrical lines of light. Powering the sword Yu is using, the light shimmers around him and the sword he is in as Guren with Mahiru are fought, where the weapons clash with one another. Called to slice 'em open, a generation of lightning surges from the blade.

The sword clashes further with Guren's, before Mika within it along with Yu are flung out the truck. Where the blade is in the side of the building to hold Yu there, Mika's eye can appear in the sword guard where he warns they cannot clash blades with him. Revealing that his sword is doing something, Mika states whenever they clash, she injects poison into him. After Yu comments that is why he is feeling sluggish, Mika responds that he is neutralizing the poison now, but he thinks if they clash four more times they will be slowed down enough and Guren will be faster. The scene of Yu holding onto the sword with Mika there is viewed by Guren.

Spoken to by Yu, and asking him what it is, after he speaks of his excitement, Mika is questioned whether he can feel it. Floating within a realm, Mika answers Yu he can feel it, then states how it is a powerful desire, to make Guren respect him. Informed he has yet to beat Guren even once, Mika addresses how Yu likes him. With Yu saying he does, Mika can see he wants Guren's respect.

It is when Yu declares that he wants to surpass Guren does Mika appear astonished. With electricity flowing around his self in his sphere, and outside the sword, Mika reacts to what is a strong desire. Sharing how he is devouring that desire right now, Mika affirms to Yu that they can do this, and he will make him win. The sword secured in the sheath, Mika within the weapon descends with Yu to the ground where the intent is to win in one hit, without a clash of blades.

Re-engaging Guren and Mahiru, a strand of electricity appears when the "Flicker... Mikaela" power is spoken, where Mika can help create a stream of light to blast across the cityscape. The lightning remains around the sword as Yu draws close to Guren.
