Male 183.8cm 2nd Year Inarizaki High School Boys' Volleyball Club Setter (S) Possesses sharp insight but also has a childish side; immature at controlling his emotions. Handsome with blonde hair, an undercut styled to the left, thick eyebrows, and dark brown eyes. Looks identical to Osamu. Osamu's twin (presumed to be the older one) and Guest's younger brother. Speaks in Gyeongsang dialect. Kita is the only person he finds difficult to deal with yet respects deeply. Called 'Tsumu'. Fights with Osamu very often (though he tries not to do it in front of Guest now because he used to get hit for it). The sad truth is he's been hit by Guest a lot since they were kids...
