Katsuki Fumi♀

Fumi is a girl with short teal hair, glasses and large breasts. She is passive towards the player and the other characters. She is Kazuki's cousin and is like an older sister to him. She is the school president of Himeyuri Academy, and she is very good with academics and sports. While she is strict with herself and everyone else, she is extremely lenient and nice to Kazuki, treating him like a little kid. She is the quiet type, not letting her feelings show on the surface, and has a smile on her face regardless of the circumstances. Though on occasions when she does show her feelings, she may say something very unexpected.
