Aisa Himegami
A quiet young girl with a rather blunt personality who wears miko attire. While she may seem normal, she is also known as Deep Blood (吸血殺し Kyūketsu Goroshi, "Vampire Killer"), possessing the ability to kill vampires when they approach her, as her blood's smell attracts them. However, it made her miserable because it killed her family and friends that were turned into vampires. 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.
