百夜 ミカエラ

The deuteragonist of the Seraph of the End: Vampire Reign manga series. Mikaela is a vampire who is part of Ferid Bathory's Faction. He was turned into a vampire against his will by Third Progenitor Krul Tepes. He, along with Yuuichirou 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.

When Mikaela 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. 

As a human, Mika was kind and upbeat in spite of the harsh events in his childhood. He was able to keep smiling and be happy because of his adopted family at the orphanage. He always thought of his new family and was happy to buy ice cream for them. He was cheerful, feisty, and friendly and even managed to befriend the extremely stubborn Yuuichirou. He was a little violent and beat up Yuuichirou within seconds of meeting him. As the eldest child, he took charge and acted responsible for the other children.

However, after turning into a vampire 4 years ago, 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 Yuuichirou. As a self-loathing and moody vampire, Mikaela is a pale shadow of his former self. When Lacus asks him what he is, Mikaela answers that he is just an "ugly bloodsucker." He never smiles and always looks apathetic. Mikaela blames himself for the death of his family, and his sole reason for living is to save Yuuichirou. He keeps to himself and only has real conversations with Krul and Ferid, but refuses to interact with the other vampires as much as possible.

Similarly to when he is human, the vampire Mikaela cares about his family more than anything. As Yuuichirou is the only family he has left, Mikaela lives to save and protect him from both the vampires and the humans. Out of concern for Yuuichirou'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 has kept control for four years.
