Aoi, Haruka

Haruka is Erika's little brother and becomes a freshman at Hikaru and Chihiro's high school. He is often mistaken as a girl due to his androgynous good looks and falls in love with Chihiro, as she is the first person to tell that he is, in fact, a male. He joins the basketball club only because she is the manager of the team. Haruka feels threatened by Shinobu's presence since he used to date Chihiro and dislikes him for the way he presently treats her. Haruka reminds Hikaru of Shinobu, since he was like him when Shinobu was in middle school.
