Ai

Ai is a famous thief of Lost Precious, called "Odd Eye" (because of her one golden eye). Her tattoo is really a Lost Precious which allows her to transform into a half wolf. Furumori, Ai's master, placed it inside her as an experiment on integrating a Lost Precious in a person. She was taken from her home by Furumori and he lied to her saying that her family was dead and that she was born a half wolf
