Міямура Леона

She is Toranosuke Miyamura's older sister. She is seen to have this abstract and cold personality towards people around her and is seen to inflict violence on those who come around her. She is also seen as crazy by Yamada, but she really care for her brother as when she thanked Yamada for being Toranosuke's friend and refused to get her brother mixed up in the witches.
