Kayano Mina♀

Hajime's classmate and a member of both the handicrafts club and student council. At first glance she appears to be a beautiful girl, but her personality is considerably straight-laced. If Hajime isn't participating in the club activities she will mercilessly kick him. On the other hand, she seems to trust him so she is a bit of a tsundere. Her grades are excellent and she can handle exercise to some extent, but she has to make a serious effort to do so.
