Mikaela Hyakuya/Relationships

Mikaela Hyakuya experienced abuse and neglect from his parents before being placed in the Hyakuya Orphanage with other children when he was younger. Meeting Yūichirō Hyakuya he would consider members there his family, something that maintained when transferred to an underground vampire city. Due to Ferid Bathory, he would witness those he cared about be systematically slaughtered before he was forcibly turned into a vampire by Krul Tepes. His thoughts of finding Yu again would sustain him over years. On account of his knowledge of Guren Ichinose's background and his actions towards others, Mika would distrust and be hostile to him. Whilst Mika rarely interacted with other vampires he would come across them and various other characters throughout the Seraph of the End series, which affects himself and the story. This article details Mika's relationships with other characters.

Mrs. Shindo
After joining a religious cult, she becomes delusional. She tells Mika that he has a special name and is a good child but never stops her husband from beating him. While Mr. Shindo speeds down the interstate one night while drunk, she pushes Mika from their vehicle and tells him to jump, ignoring his begging. Ironically, he sustains severe injuries but survives while his parents shortly die in a major car accident immediately after.

Mr. Shindo
After Mrs. Shindo begins to lose her sanity, he begins drinking alcohol and becomes an alcoholic. He beats Mika every chance he gets, and Mika constantly tells him he loves him to try and make the beating stop. It is ineffective. Speeding while drunk makes him have a car accident that kills both him and his wife.

Yūichirō Hyakuya
At eight years old when Yu first arrived at the orphanage Mika greeted him and was not discouraged from Yu rejecting his friendship. With Yu's anger heading towards violence Mika beat him up right after they met. Mika was understanding and assured Yu that things would become better from that day on. Together, they helped look after younger orphans in the vampire city as well when they were taken underground. Mika would show concern for Yu when he came into conflict with vampires and make an excuse for him so he did not have to go to Ferid's mansion. When the escape from the city was revealed as a trap Mika was calm as he reminded Yu to not forget they were family. In order to give Yu a chance to escape, Mika sacrificed himself and was fatally wounded but was happy to think he could pass away knowing that Yu had made it. As the last surviving member of his chosen family Mika is extremely protective over Yu, and saving him is Mika's sole reason for living. Mika was startled at seeing Yu again for the first time in four years at Shinjuku to the point of physical inaction. When an opportunity arose Mika carried Yu away from the fighting and tried to persuade him to leave everything behind and escape with him whilst there was still time. Mika felt his concerns regarding human experimentation were realized after witnessing Yu transform. Unable to regain him and having to retreat Mika was extremely reluctant to leave Yu behind. Seeing him again caused Mika to shed tears for the first time since becoming a partial vampire. At Nagoya Mika would question Aiko Aihara for news on Yu's whereabouts as he searched for him. Spotting him amongst the retreating members of the Moon Demon Company Mika seized the chance to gain Yu and charged through the entire gathered squadrons to reach Yu at the back. Physical injuries from many soldiers including the strongest members did stop hinder Mika's determination to get Yu again. After getting him to safety Mika's idea was to tell Yu what he knew of their background but would not drink blood and become what he knew Yu hated the most. At last persuaded Mika would drink his first human's blood, that of Yu's which made him a complete vampire with red eyes. Whilst Yu was set on rescuing his squad Mika attempted to get Yu to listen to him. Mika would stand back to back with Yu at Nagoya airport when human soldiers were being massacred. He would then defend Yu from Guren and help in the brief fight against him.

"What the heck, Yu?! Why're you suddenly trying to keep secrets from me?"

- Mika to Yu

After escaping, Mika would keep watch over Yu with him being the only one he trusted. Whenever Yu is involved on the battlefield, Mika becomes reckless. When injured by Fuola Honte, Mika ha no concern for himself rather he told Yu to stay back to keep him away from danger. After seeing his actions Mika is willing to kill Guren despite Yu's heavy protests that he is also family. He is willing to eliminate Guren as a threat even if Yu hates him for it. Although sometimes Mika finds it hard to emphasize the dangers that he sees Yu as being oblivious to Mika is patient in explaining them but will also take action if it takes too long. In chapter 55 Mika holds Yu's hand to comfort him after they see the deceased members of their family again. Mika was concerned for Yu's wellbeing when he wanted to save Shinoa and tried to persuade Yu to not give away information for free to Kureto. Mika was also somewhat distressed at Yu offering his memories for experimentation. With Yu led away and with him captured by the Hyakuya Sect Mika remained unwaveringly committed to locating him amongst the chaos breaking out across the city with the first present and an invasion occurring.

Mika's dedication to being there for Yu would pay off as he would be the first to successfully locate Yu. After cutting him loose Mika was ready with Yu to fight against Guren as a demon, Mahiru and Noya. With Yu convinced Guren was still their friend Mika changed tactics to convince Yu he needed to take part in a pre-arranged plan, one that involved them escaping. During the fight they kept close together and Mika took a hold of Yu and used his own body to defend him from Guren's sword. Worried about Yu having to draw upon more demon power, Mika would try and pull him from the ceiling for them to escape. With Yu's safety at risk Mika largely sacrificed himself to fend their enemies off. In chapter 90, Mika would see Yu upset far below as he was lifted into the sky and after saying for him not to cry Mika told Yu that he loved him. Which comes to show that Mika is in love with him.

Akane Hyakuya
One of the children from the Hyakuya Orphanage. She was younger than both Mika and Yu, but she was at the orphanage longer than Yu. She was the third eldest and was kind and responsible. Mika would hand Akane the curry ingredients to prepare. She was the last person Ferid Bathory killed when Mika's family tried to escape Sanguinem in 2016. Ferid has since preserved her body and is holding it hostage, along with the corpses of the other orphans.

It was revealed that she had a crush on Mika as well although he did not seem to return the feelings. With the time passed, and the costs of human resurrection and that Mika has Yu he is not in favour of resurrecting the dead largely due to it being Guren involved with it and the technicality that Akane perished after the apocalypse event.

Junji Haiyama
A boy living at the Hyakuya Orphanage with them in Shibuya prior to the Apocalypse in 2012. Miyuki Yamada (Mahiru Hiragi) "adopts" him when he is four years old, and Mika has to calm him down before he leaves.

Yuki Endo
One of the children living at the Hyakuya Orphanage in Shibuya with Mika, Akane, and Junji back in 2012 prior to the Apocalypse.

Mahiru Hiragi
A teenage girl who used the alias of Miyuki Yamada while interacting with the Hyakuya orphans. She "adopts" a 4-year-old boy named Junji and claims to accept him as part of her family while actually using him for experimentation. Although never met, Mahiru probably visited him sometime after.

Both Mikaela and Mahiru were sired by Krul Tepes. He did not appear to recognise her when he was assailed by the spirit of Mahiru and the sword and spell tags she could use. Mika abandoned the battle with her in favour of rescuing Yu and would tell him she was trouble. As Manhiru along with Noya were the separated aspects of Guren's cursed gear weapon, Mahiru-no-Yo, Mika would fight alongside Yu against her.

Saitō
He is a member of the Hyakuya Sect who has undergone extensive experimentation for increased strength and regenerative abilities. He gave Mika money for ice cream and things for the children and watched over them from time to time. In reality, he was actually a vampire. It dawns on Mika that he may have been manipulated by this seemingly kind person.

Krul Tepes
A third progenitor and the queen of Japan. She is familiar with the seraph of the end. In 2012, Krul intentionally disobeyed orders to kill the Hyakuya orphans and rescued Mika's family by raising them as livestock in Sanguinem instead. Four years later, Mika would owe his existence to her a second time although now reluctantly and he was transformed into a vampire against his will by Krul. Whilst it saved his life Mika detested being anything related to vampires yet when he refuses to drink human blood he is permitted to sustain himself off of Krul's. Four years later Mika and Krul have a close relationship and she is the only vampire seen who he interacts without any ignoring as is the case with others. They are close enough that in a state of blood lust Mika can hoist Krul off her throne, drink directly from her neck then toss her aside once he realises what he done. He checks first to make sure Krul has nothing negative planned for Yu then is entrusted with a sensitive mission. Mika is instructed to disappear during the war and find Yu after having her true agenda whispered to him. While Mika acknowledges that Krul may regard him as a pet Mika feels at least Krul will hear them out. When Ferid and Crowley ambush both Krul and Mika he complies with her orders that only he hears and rescues Yu before the humans.

Three months later with Yu's demon situation only getting worse and the squad deciding their options, Mika's unique input is for them to save the vampire queen, Krul from her imprisonment. Finding one another again in Osaka Mika and Krul's secret plan remains that and they pretend not to know one another around other gathered vampires to keep it that way. Along with the rest of the squad they mean to rescue Krul as their best course of action.

Ferid Bathory
Growing up in Sanguinem, Mikaela approached Ferid Bathory and was friendly to the vampire noble. In exchange for letting Ferid bite him and drink his blood, Mika received money and good food that he shared with his orphanage family. With Yu wanting to leave the city Mika's true goal was to steal a map, and he succeeded in stealing both that and a pistol from Ferid's mansion. However, Ferid waited for them at the exit and slaughtered the Hyakuya orphans. By sacrificing himself, Mika was able to give Yu the opportunity to escape, but Mika was fatally wounded by Ferid and without intervention would have likely passed away from the injuries to his arm and body. Once Mika is a vampire he spends four years living with the individual who betrayed his trust and murdered those who he held dear. Mika largely ignores Ferid, he will walk away when he notices him yet will point his sword at his neck in private when approached. To not give Ferid any satisfaction Mika states that he is only angry at himself for leading his family into a trap he knew nothing about. After grabbing him by the throat and saying he will kill Ferid if he turns Yu into a vampire Mika whimpers when Ferid places his hands on him. As before he is dependant on how Ferid can practically help, from providing information to rescuing Yu for Mika. He is content to have Ferid's assistance in such cases but Mika does cut off Ferid's arm on the battlefield when he touches Yu. Against Ferid from hassling children in Sanguinem Mika was invited to the progenitor council meeting where his presence was used to make Krul feel uncomfortable in front of other ruling vampires.

"You don't understand. Ferid is manipulating all of us into thinking what he wants us to think. We're already completely caught up in his little games.... Yes. And he's an eccentric too. He's the last person anybody wants to get involved with."

- Mika to Shinoa Squad.

With Ferid sighted again Mika advised the squad that Ferid could not be trusted. Whilst he attempted to remain calm and focused on having Yu the same Mika was furious after Ferid bit Yu and drank his blood and said he would never forgive him. After acquiring a sinful key Mika was ordered to hand it over to Ferid or he would have all his clothes stripped off with unspeakable things done to him. Handing it over Mika questioned what Ferid was up to this time to maintain some semblance of control. Mika cannot do much against someone who has inflicted such deeply sorrowful experiences on him whether due to a lack of strength to internalizing the trauma then needing Ferid for the information he knows.

Lacus Welt
He is a city guard that often works with Mika and René. Mika's power impresses him, but he is concerned about Mika not drinking blood, considering him weird for not doing so. He is chatty and often tries to start conversations with Mika, but Mika usually answers with silence. Lacus says he does not care whether Mika lives or dies and for his part Mika is indifferent to this indeed most of the views from Lacus.

René Simm
A coworker in missions including destroying Four Horseman of John to secure their human food supply. Mika is accused of stealing glory, but Mika is uninterested. He is quiet and more serious than Lacus. If no one outranks him, he will direct the two of them on the battlefield. Unlike Lacus, he is unconcerned with Mika's odd behavior so long as Mika does his job.

Mitsuba Sangū
One of Yu's squad members. She defends herself from Mika when he tries to reach Yu, after he had just fought his way through an entire regiment, but Mika knocks her aside. After Shinoa protects Mika and tells him to escape with Yu, she stands beside her to defend him from their own army.

Shinoa Hīragi
A sergeant of the Japanese Imperial Demon Army's Moon Demon Company. She first met Mika when they were eight years old while she was delivering messages from her sister, Mahiru Hiragi, to Guren. Eight years later, they meet on the battlefield, and Yu considers her to be a friend. Mika nearly died protecting her from Yu in Shinjuku for that reason, but claims she is just using him. She returns the favour in Nagoya when she defends Mika from her compatriots in the Moon Demon Company and even attacks Major General Shinya Hiragi to save Mika's life, and labelled as a traitor as a result. She allows Mika to escape with Yu and tells him to meet up with them at the Nagoya Airport later on. Thanks to her intervention, the rest of her squad joins her, and Mika is able to flee with Yu. By the time the battle in Nagoya comes to a close, Mika leads Shinoa and the rest of the team to safety, away from both humans and vampires. Shinoa is the only human besides from Yu to have earned his trust so far.

Shihō Kimizuki
One of Yu's squad members. He carries Yu on his back when Yu is unconscious in Nagoya and tries to prevent Mika from taking Yu. Mika headbutts and throws him out of the way. After Shinoa protects Mika and tells him to escape with Yu, he stands beside her to defend him from their own army.

Yoichi Saotome
One of Yu's squad members. He is the first one to recognize Mika in Nagoya and does not want to fight Mika. When Mika first grabs Yu, Yoichi jumps on top of him and hugs him from behind, saying that anyone who is Yuichiro's family is their family. Mika pushes him off and then tells him to not be stupid and to die. Thanks to his actions, Shinya Hiragi is able to stab Mika from behind, but Yoichi urges him not to kill Mika. After Shinoa protects Mika and tells him to escape with Yu, Yoichi stands beside her to defend him from their own army.

Makoto Narumi
The sergeant and leader of his squad in the Moon Demon Company. In Nagoya, his squad fights against Mika first. After Rika and Taro block Mika's attack, he makes the first offensive strike against Mika, but Mika blocks it. Mika runs past him and his squad to reach Yu. Makoto is baffled and comments that running into the middle of their company is a stupid move. After Shinoa and her squad protect the vampire from the Moon Demon Company and let him escape with Yuichiro, Makoto follows Shinya's orders to not kill Shinoa and protects her from another soldier. After this, he sees vampires kill two members of his squad.

Guren Ichinose
Currently the leader of the Moon Demon Company in the Japanese Imperial Demon Army. Mika was eight years old when he first meets Guren in the light novels. When Mika asks about him, Saito of the Hyakuya Sect says that Guren is a pervert. When they meet again on the battlefield eight years later, Mika doesn't consider him very strong and defeats him with some help from Ferid and stabs him through the chest with his sword, making him cough up blood. In exchange, Yu goes into a rage and stabs Mika before recognizing him. Yu cares about him. This person is responsible for Yu's transformation in Shinjuku, and he has been collecting and experimenting on the seraph of the end. He wants to capture Mika as well. Crowley Eusford captures him in Nagoya.

He works with her to deceive the other vampires into thinking that the Automobile Museum is the humans' target. Afterward, she insists that he kill her because suicide would look too suspicious, but he tells her to do it herself. She then attacks Mika, and with either a quick death or torture by other vampires as her fate Mika provides the former without ever learning her name. He looks slightly sad for a moment afterwards. She is the first person Mika is shown to actually kill.
