Teruhashi Makoto/Relationships

Teruhashi Kokomi
Kokomi is the sister of Makoto and he loves her very much. His feelings, however, extend beyond normal sibling relations. He believes that he is destined to marry Kokomi one day. She, on the other hand, resents him for his protective nature and what he did to Saiki.

Saiki Kusuo
Makoto and Kusuo mutually dislike each other. Kusuo is disgusted by Makoto's incestuous feeling towards Kokomi. Makoto thinks that Kusuo is a creep trying to stalk Kokomi at all times, but Kusuo points out that he's the creep, if anyone. The only thing they have ever agreed on is that they don't want Kokomi to become famous, due to the trouble it would cause them. However, Makoto went to Kusuo for help when Kokomi was very upset with him.
