有森 和美

She is a female college student who lives near the protagonist's house and attends a university in the city. She has a gentle personality and is an optimist who doesn't worry about small things. She attended an all-girls school so she has no experience with boys, but she doesn't feel uncomfortable around the protagonist because she played with him when he was little, and unconsciously acts like an older sister to him.
