Basketball ace in the school that for some odd reason likes to pick fights with Ryou and Akira. Despises those that don’t take sports (life) seriously.

The real reason he is hostile toward Akira and Ryou is that he is actually a siscon and envious of Akira and Ryou to have a real imouto beside them. But he then falls in love with Ryou after he sees Ryou does a slamdunk.
