Yoshiki Kishinuma
Giving off the aura of a delinquent, Yoshiki faced difficulty in school due to issues at home. Yoshiki considered getting himself expelled from Kisaragi Academy since he could not find a reason to continue attending. However, Ayumi changed Yoshiki's mind after standing up for him against their PE teacher Mikio Tsubota. Yoshiki is prone to outbursts of frustration when faced with difficult situations. Though he often means well, his actions can appear cold or even selfish to those around him.
