Himegami Aisa

Aisa Himegami (姫神 秋沙) is a magician with anti-Vampire blood.

Profile
Known as "Deep Blood" and has the ability to kill vampires when they approach her, resulting in many of her friends dying. This prompts her to go to Academy City, hoping to find a way to get rid of her powers, until she meets the alchemist Aureolus Izzard. She cooperates with him because he told her that her blood can be used to save the life of a person he cared for (Index) in return for helping her get rid of her powers. When Aureolus learns Index's life was already saved by Tōma and tries to kill him, Aisa attempts to defend Tōma, which prompts Aureolus to use his alchemy to try to kill her as she was now useless to him. Her life was saved by Tōma who dispelled the spell on her with his right hand. When she asks Tōma about why he saved her, he told her that he did not have a reason to rescue her. After the incident, she lives with Tōma and Index but later moves to Komoe's apartment and wears a magical power-blocking cross, which according to Index is the bare minimum of what makes up a 'Walking Church' barrier. She subsequently becomes a student at Tōma's school and is in his class.

According to the novels (To be precise: vol.2, end of chapter 3, [Intermission 2]) Himegami's Dream isn't to live a normal life, but to become a 'magician' like those in fairy tales who can even disregard the laws of nature, to save people that have been abandoned. She has this dream because her village was all turned into vampires by a passing vampire that was afraid of her ability, and decided to turn everyone into vampires to kill Himegami, but in the end they, the intruding vampire, her friends, her parents, all were killed by the ability Deep Blood. At the start of vol.2, she joined Aureolus for the short term goal of sealing her power so she can't kill vampires, and afterwards to continue the dream of becoming a magician. After vol.2, she was content with staying with Touma as it seemed to her if she stays with him she'll achieve her dream somehow, in addition to her ability being sealed by the 'Walking Church' cross-pendant Necessarius gave her.

Personality
A quiet young girl with a rather blunt personality who wears Miko attire. Her ability made her miserable because, aside from sucking blood, vampires were just like humans. Ever since Tōma saved her life, Aisa started to have feelings for him, which is ironic as she once joked that Tōma's life was like a dating sim.
