Fujino Natsuki

The protagonist's classmate and one of the apartment tenants. Doesn't show much emotions, therefore she is considered a cold girl. She came very far to attend this school so she lives in the apartment. She can do everything beautifully, but if not requested she will not do anything, so in short, she has zero motivation. In truth she doesn't actually hate helping other people, and when requested she is actually happy. Kauruko considers herself her rival. However, Natsuki does not take the rivalry seriously.
