She lost her parents at a young age, and since she had no close relatives she was taken in by an institution. She met Miho shortly after entering the institution. She is Jun's first friend and his best friend. She is not very good at talking to people, and doesn't say much. (She can talk normally with Miho and the other residents of the institution) She is like an older sister to the other children at the institution, and everyone loves him. She does not live a wealthy life, and does various part-time jobs. She is good at swimming, and has been invited to join the swimming club. To save money, she does not have a cell phone.
