In contrast to her brother, Chizumi is rude. Her brother is a manipulator and murderer. Chizumi also stalks around, typically women and other children. She isn’t prone to murder. Of the two, Chizumi is also always honest regarding both Yuuma and herself, no matter how unpleasant the truth may be. Chizumi had apparently developed her taste for brains. She kidnaped boy she fell in love with, only for him to escape. She enjoys messing with/licking and biting her love interests.
