A second-year student at Sankai High School. Born on June 12th. Height: 181cm. Blood type: B. The third of four brothers. His favorite food is tonkatsu. His least favorite food is umeboshi (pickled plum). His hobby is dating. His motto is "bright eyes, white teeth."
He has a bright personality and is a joker who loves women, but he also has a strong friendship side. He is an all-around athlete and has a third-degree black belt in judo.
He is a member of the judo club at school, and despite being a second-year, he is skilled enough to serve as the club's captain, but he often sneaks out during club activities and joins the girls' club practice without permission.
Among the girls at the surrounding high school, being spoken to by Shin is considered the minimum standard for a girl to meet up with. His catchphrase when he sees a cute girl is, "Hey, you there! Won't you spend your youth with me?" According to him, he doesn't pick up girls indiscriminately, but has a motto of only picking up girls who are his type (cute girls with slender legs, beautiful skin, not too jaded, and long hair). He became close with Erika, the president of the broadcasting club, and later they started dating.
