Aisa Himegami

She is also known as "Deep Blood" and can kill vampires when they approach her because the smell of her blood attracts them. After the ability killed family and friends who had become vampires, she went to Academy City hoping to get rid of her powers and cooperated with Aureolus Izzard after he said her blood could save someone he cared for in exchange for helping her. Tōma later saves her from Aureolus, and she eventually moves to Komoe's apartment and wears a magical power-blocking cross.
