He kind of looked like Okita Sougo from Gintama XD

True. The difference is that Sougo is a real S, even in the show (sooo hot) but Sakurai doesn't seem to be one in the manga, or anime. From the way he behaves he is either a really closeted S, or a M or neither. M is the most likely based on his behavior in KnB. That makes this dj only better though, what an unusual perspective.

He has a meek personality until he plays basketball. He hates losing and almost has this alter ego that's probably as crazy as the one we saw on the dj lol
