Kurusu Shou

Syo is an egocentric boy who treats Haruka like his servant and calls himself "the prince of music". Due to his short stature and his "cute" appearance, he is called chibi-chan and is constantly pursued by Natsuki. He plays the violin, is surprisingly good at karate and has a brother called Kaoru.

He shares a room with Natsuki from Class A and is in Class S.
