Yuuma's childhood friend. She is a mild tsundere with a tendency to try to force a "healthy and proper lifestyle" on him whenever is possible, bribing him with her homemade lunches in order to get him to come to school. While Yuuma seems to think she might dislike him, it is obvious to anyone else that the opposite is actually the case.
