Rinna Sawaki

A second-year transfer student. Wataru meets her at Takashi's bar while he's drunk. They chat and then leave. She officially enters his school, joining his class and dorm the next day. She acts sullen and obstinate to both students and faculty. She skips the welcome party that the other dorm residents arrange for her, telling them that she doesn't want to make friends and faces the pain of parting with them in only a years' time. Wataru shouts to her his vow to that he will force her to become friends with them.
