Shiho at first glance seems to be a quiet and reserved girl who rarely talks to anyone and doesn't smile much. In fact, the only person she lights up around at school is Ann. She lacks confidence to a significant degree, thinking her volleyball skills are her only valuable attributes. However, it is said that she used to be an outgoing and sociable person until she received a series of advances, as well as abuse, from Kamoshida at Shujin Academy.
