Tachibana is a male student of Sainan High school, who is yonger than Rito and belonged to the same soccer club in junior high school which Rito belonged, too. Later on, he attends to Sainan High School and reunite with Rito. His appearance is characterised by eyeglasses and blemished face. He often prefixes "-su!" at the end of conversation. He tends to be enamoured by girls and to be mischevously flippant. He considers Rito, who is somehow close to beautiful girls, as "a master of love" and he asked Rito for advise to relate  his ideal seniors Haruna and Yui. He is not usually rash, as unable to sufficiently talk with his ideal girls, vive versa, he has been excited by seeing Yami's thighs and then two or three hairs have been cut by Yami. He is a fan of Run since her debut, and he has gone after Run with Motemitsu and Principal in Run's performance. He doesn't apeear in Darkness.
