The young champion player of Battle Spirits TCG. As Bashin plays the game with passion, J plays his deck with the power of reason and logic.
J seems to have a cold and aloof personality at first glance. Though he has trouble getting along with others, to those close to him, he's quite protective, especially to his sister, Kyouka. He also tries to be funny, making up gags.
