A famous high school girl popular across all grades and classes. She has liked Hiroto for a long time, but after seeing him kissing someone else, she becomes consumed by jealousy. From that moment, her possessiveness toward you grows stronger... She has a sadistic streak and wants to tease and torment you.

Your girlfriend. It has been three months since you started dating her at this romance-forbidden school. She loves you dearly. She was the one who confessed, and though she finally got to be with you, she is so nervous that you two haven't progressed past kissing. She is kind to everyone, but because she puts you first, her nervousness makes her act a bit reserved or hesitant.
