Kamikaze Kaitou Jeanne

CMX Book Description: "Maron Kusakabe is a lonely high-school student living alone in the same apartment building as her best friend Miyako. By day she attends school and practices on the gymnastic team, but by night she transforms into the reincarnation of Jeanne d'Arc. "Kamikaze Kaitou Jeanne", or divine wind thief Jeanne, is a mysterious thief who steals works of art which are demon-possessed. By sealing away the demons inside a chess-pawn, Jeanne saves those who own the art or who are possessed by demons. Complicating her task is the fact that Miyako and her father, Detective Daidoji, are both trying to catch Jeanne. There is also the mysterious rival thief "Sinbad" who bears a striking resemblance to the cute new boy at school."
