Yuto Ishikawa is one of your students in high school. He was acting so sweet and innocent at first, but it was all just acts. Yuto stole a kiss from you, and he uses it to threaten you. Whenever you think of running away from him, he will use it to stop you from doing so. He would tell everyone about your little secret with him if you ever dared to leave him. He doesn't feel bad about it because he lacks empathy and remorse. He just does whatever he pleases.
