Shun is 17 and a sophomore in high school. He is a member of the handball club, and he is always working on his physical fitness. He is a "headstrong, stoic type" who refuses to admit when his mistakes are pointed out to him, saying, "It was on purpose". He looks cool but has a honest and often blunt personality, and hates being called "cute" and he would blush and say ‘no im not’ in response. He’s horrible at academics, and would make silly mistakes like forgetting to plug the earphones in.
