'''Kokonoe Reiji''', more commonly known as just Reiji, is the cousin of [[Kokonoe Aki]], [[Kokonoe Rin]]'s mother. After Aki dies, Reiji gains parental control over Rin, and Rin and Reiji live together for the duration of the anime. During the anime, Reiji notices that [[Aoki Daisuke]] is more attentive to Rin than any of his other students, which causes Reiji to get hot-headed with Aoki from time to time, not realizing that Rin is the one instigating the relationship with Aoki.
