Mikaela Hyakuya

Mikaela Hyakuya 「百夜ミカエラ, Hyakuya Mikaera」 is the deuteragonist of the Owari no Seraph series. He was turned into a vampire against his will by Third Progenitor Krul Tepes. He, along with Yūichirō Hyakuya and a few others, possesses the seraph gene, which is relevant to the forbidden taboo and a focal point of the story Seraph of the End.

Appearance
As an 8-year-old human child in the light novels prior to the Apocalypse, Mika appears wearing short jean shorts. He wears a white hoodie over a collared shirt. Sometimes, he is also shown wearing an over-sized jean jacket. He has short, wavy blond hair and blue eyes, which gives him the appearance of a foreigner.

As 12-year-old human livestock, Mika wears the standard livestock uniform. He wears the capri shorts and a hooded shirt. He is barefoot like the other livestock.

After becoming a vampire, he grows fangs, but his eyes remain blue. His hair hides his ears, so it is unknown if his ears are pointed or not.

When he is 16, his hair reaches down to his shoulders. He wears the standard uniform of the vampire soldiers. He wears a black collared shirt with cuffs and white trim. He keeps it buttoned over his neck and held in place with the vampire insignia. Over the black shirt, he wears the white military jacket with black trim and decorated buttons. It also has the black piece of the vampires on the left shoulder and black cuffs with white buttons that nearly reach up to his elbows. He wears white gloves. He has a thick black belt encircling his waist, and he wears two smaller belts below it forming an X over his posterior and front. He also keeps his sword at his left hip. He wears white pants with black boots reaching up to his upper thighs. The boots have three large buttons at the upper lateral sides and three smaller buttons coming up from his ankles. The soles, toe, and heels of the boots are white. A decoration over the heels consists of a small ribbon coming from either side to make a V with a small white circular detail keeping them in place.

Mika often wears the standard vampire white cloak with a hood as well. The gold decoration on it has blue gems hanging from its chains.

In chapter 26, Mika, Lacus, and René wear new uniforms. This uniform consists of a long white shirt with black details and straps, including an inscription over the left breast. His shoulder and neck pieces have numerous straps tying them together, and a black collar holds them to his neck. A modified version of the gold decoration that kept his collar together over his black shirt in his previous uniform is now inverted and without a line through its middle, and it is at the base of his neck rather than over his collar. A white cape hangs down from the back of his shoulders to his upper thighs. The shirt also has black cuffs reaching from the wrist to the elbow. He continues to wear white gloves. He wears two belts that meet at his right hip, and he continues to have his sword on his left hip. His boots reach up his thighs like before, but they are solid black without any white or button details. This outfit is more form-fitting than the previous one and does not have as many trim or button details. It also has fewer layers.
 * Anime: Livestock wear shoes in the anime. As a vampire, his boots have less decoration and appear completely black.

Personality
As a human, Mika is kind and upbeat in spite of the harsh events in his childhood. He is able to keep smiling and be happy because of his adopted family at the orphanage. He always thinks of his new family and is happy to buy ice cream for them. He is cheerful, feisty, and friendly and even managed to befriend the extremely stubborn Yū. He is a little violent and beats up Yū within seconds of meeting him. As the eldest child, he takes charge and acts responsible for the other children. As he grows up in Sanguinem, he becomes more cunning and willing to do whatever dirty work is necessary in order to help his family, but he refuses to let any of the other children take such hardships. He even approaches Ferid Bathory and lets him drink his blood on multiple occasions in order to help his family escape. Although he feels miserable and even breaks out crying in front of Yū once, he typically maintains a carefree and happy persona in front of the children. He wants to make sure they all still have hope. In chapter 3, Yū describes Mika as "smart" but "always stupidly nice to all of us."

Mika uses his courage, cunning, and wits to lead his family past vampire patrols and to an exit in the city. Even though Mika sacrifices himself to let them escape, he is only able to save Yū. When Yū refuses to leave his side, Mika pushes him away and is happy that Yū finally accepted them as his family. He states that he can die in peace as long as at least Yū survives. When Third Progenitor Krul Tepes offers to turn him into a vampire and give him immortality, he refuses.

She turns him anyway, and he comes to hate both vampires and humans. He hates vampires because of his history with them, and he hates humans for using and experimenting on Yū.

As a self-loathing and moody vampire, Mika is a pale shadow of his former self. When Lacus asks him what he is, Mika answers that he is just an "ugly bloodsucker." He never smiles and always looks apathetic. Mika blames himself for the death of his family, and his sole reason for living is to save Yū. At the end of chapter 3, Ferid finds Mika in a basilica with his head bowed and implies that Mika goes there often. It is unknown if Mika is praying for Yū's safety, praying for control over his thirst, or seeking repentance for his perceived crimes.Except when he is with Yū or Krul, his expression is typically cold and disinterested. He keeps to himself and only has real conversations with Krul and Ferid. Although Lacus repeatedly attempts to make conversations with him, Mika usually ignores him and refuses to interact with the other vampires as much as possible.

Ferid describes the vampire Mika as "overwhelmingly powerful and arrogant." Mika rushes into battle without any interest in glory, but he prefers to fight alone rather than have the other vampires backing him up. His arrogance and lack of concern for his own life have caused him to be extremely reckless on the battlefield, particularly when Yū is involved. After meeting Yū in chapter 12, he does not defend himself and lets Yu stab him through the chest. In chapter 14, Mika uses his own body as a shield to protect Shinoa from Yu, and Yu stabs him through the back at full power. The wound is severe enough to require curse detoxification. In chapter 35, he dives into a company of human soldiers and receives many injuries, and Shinya Hīragi stabs him through the back with his Black Demon Series weapon.

Unlike other vampires, Mika does not view the humans as livestock. However, he lusts after a girl's blood in chapter 5, attacks a young girl in chapter 26, and wants Aiko Aihara's blood in chapter 30 after he kills her. Ferid also tempts him with the blood of a young boy in chapter 22. Although Krul is the only person he bites so far, he desires human blood so badly that he can hardly stand it. Similarly to when he is human, the vampire Mikaela cares about his family more than anything. As Yū is the only family he has left, Mika lives to save and protect him from both the vampires and the humans. He cuts down his vampire "comrades" who may be a threat to Yū without any hesitation, and Ferid's taunts about Yū send him into a rage. Out of concern for Yū's hatred of vampires, he refuses to drink human blood and become a true vampire, preferring to remain dependent on Krul's blood. Despite the tremendous pain, blood lust, palpitations, and sheer agony of resisting the urge to drink human blood, he keeps control for four years. After he attacks a young girl in chapter 26, he manages to stop himself before drinking her blood but remains horrified by his vampirism. He wants to avoid drinking human blood until he rescues Yū from the humans but does not reveal what he plans to do after rescuing Yū, whether he intends to become a true vampire or die. Later on, it appears he planned to die, but Yu insists on Mika surviving and drinking his blood instead. Mika spoils Yu enough to give into his demands and rescue his squad members.

Mika is loyal to Krul Tepes and trusts her enough to capture Yū. However, he initially refuses until she explains what those purposes are.

History
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 was 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.

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

When Mahiru, using the alias of Miyuki Yamada, adopted an orphan named Junji, Mika calmed him down enough to leave with her.

Prologue
When Yu arrived at the orphanage, Mika wanted them to be friends, but Yū was uncooperative. Mika claimed he was the leader and picked a fight with Yu, but Mika easily defeated him. Afterwards, he told Yū 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 Yū joined them.

Shortly after, the director at the orphanage suddenly began to bleed from her nose and mouth, and she fell to the ground. The virus struck down the adult population of Tokyo while Third Progenitor Krul Tepes lead the invasion of their city. This was Christmas of 2012. For the next four years, the orphans became livestock for the vampires and moved under Kyoto to the vampire capital Sanguinem. Mika approached Ferid Bathory, and offered 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 Yū 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. Yū refused to run away and caught the gun, managing to shoot Ferid in the face. Although Yū incapacitated Ferid, Mika was fatally injured and could no longer escape. When Yū refused to leave Mika's side, Mika pushed him away until Yū finally fled to the exit. He felt relieved that at least Yū managed to escape and happy that Yū finally called him family. With those thoughts, Mika was prepared to die in peace. However, 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 ripping off his arm and crushing his throat in 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.

Second Shibuya High Arc
After becoming a vampire, Mikaela 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. He reappears at the end of chapter 3 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 Yū.

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 Yū. He once again tries to convince Mika to drinking 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 on 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 over seeing Guren get stabbed, Yū arrives. Mika recognizes him and turns around, but Yū 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 Yū 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 Yū and asks him why he did not kill that vampire when he had the chance. While Yū reveals Mika's identity to his squad, Ferid chats with Mika. Ferid says that Yū is obviously being used by those humans, and Mika claim he will save Yū. When Ferid mentions a human like Yū could never be one of them and volunteers to turn Yū 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, Yū calls out Mika. Then, Thirteenth Progenitor Crowley Eusford arrives. Ferid changes his plan from killing Yū's human allies to turning them into livestock. The skirmish begins, and Ferid steps behind Yū and grabs his shoulder, causing Mika to amputate the responsible appendage. Of course, Ferid says he was just joking about tasting Yū. Mika steps up to Yu and tells him to forget about the humans and run away with him. He lifts Yū and carries him in his arms. Playing off Ferid's comment about Yu being a princess, this position is actually referred to as a "princess carry" or a "bridal carry." Mika warns Yū that Yū is in a bad place and is being used by the humans, but Yū has no idea what he is talking about. Yū struggles and breaks free, jumping to the ground. He says that Mika makes it sound as though he is no longer human and asks if it is his fault. Mika immediately answers that it is not Yū's fault. Mika begs Yū to come with him, insisting that he is Yū's only true friend and the humans are only deceiving and using Yū. Yū 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 Yū under Guren's orders takes affect, causing Yū to transform as his seraph component runs wild. Yū screams. Yū swings at Mika and Crowley before moving to kill Shinoa, his true target. Mika jumps in the way, and Yū stabs him through the back. Mika urges Yū against killing humans. He asks Shinoa how she could dare use Yū like that, and the berserk Yū calls Mika a vampire, telling him to not interfere and saying that all humans must be killed. Guren orders Shinoa to embrace Yū to undo the transformation, so she jumps in after Yū flings Mika aside. Yū 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 Yū, 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. Yū) 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 Yū. 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 Yū'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 be become a human again one day, but Mika tells him to get lost. Ferid then smiles and asks if Mika is afraid Yū 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 Yū 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 circumstance, 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 Yū 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 Yū 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 any more, 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. She says she is his savior, surrogate parent, and owner.

Giving into his pleading, she whispers her plans for Yū 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 Yū. Mika obeys.

Nagoya Arc
In chapter 23, Mika, René, and Lacus wear their new uniforms and discuss orders to deploy to Nagoya.

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 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 Yū 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 speak in a whisper. He asks her about Yū. 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 Yū 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 volume 2.

At the end of chapter 34, he waits and watches as the battered Moon Demon Company runs toward him as they flee from Nagoya. He says it is time those humans return Yu to him.

In chapter 35, the surviving soldiers of the Moon Demon Company 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 Taro Kagiyama block his attack. Makoto Narumi attacks him from the side, but Mika blocks it. Spotting Yu, Mika leaves them and jumps past Shusaku Iwasaki and Yayoi Endo. 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 throws three kunai into his right thigh. Mito punches him before he can land and sends him into the ground in front of Shinoa Squad. Mika sees Yū on Shihō Kimizuki's back. Yoichi recognizes Mika and asks his group if that vampire is Yu's family. In the meantime, the humans surround and attack Mika. One stabs him in the back, but Mika ignores him. 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 the should stop him before Mika kills them. Yoichi protests. Mika reaches for Yū. Mitsuba tries to block him, but Mika smacks her axe away. Kimizuki drops Yū while trying to block Mika and says Mika cannot have Yū. Mika throws him aside. Mika begins to lift Yu from the ground, but Yoichi jumps on his back. He says he is not letting Mika go anywhere, and 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 Yūichiro's family. Mika knocks him off as well, telling him to not be stupid and to 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 Yū and run.

The other soldiers demand to know what she 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 Yū 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. The two argue. 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 monsters 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.

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 a 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.

Powers and Abilities
He wields a first-class vampire sword. When he orders it to drink his blood, it sprouts thorny vines that pierce through his hand and turn the blade crimson. His strength and speed grow in proportion to the amount of his blood the sword drinks.

Abilities
He was turned by a third progenitor, which makes him abnormally powerful for such a young vampire. Even before he drinks human blood and completes his transformation into a true vampire, his strength is already great enough for other vampires to believe he was turned by a third progenitor. Drinking Yu's blood completed his transformation and drastically increased his power. It also gave him eternal youth and stopped his aging process.

Until drinking human blood, Mika was dependent on Krul's blood, which had become increasingly ineffective at quenching his thirst. When starved for blood, he would attack Krul or a nearby human. Krul and Ferid warn him that going without blood for too long will turn him into a demon.

As a vampire, he has incredible strength and regenerative capabilities. He can reattach his limbs at will and survive injuries that would be fatal to humans. Only a weapon containing a powerful demon can halt his regeneration.
