Haruka Takayama

Student of Misato-West High School, the big-white hair ribbon is her trademark. Haruka didn't have friends before she met Yuu, as a result, being jealous when Yuu gets along with others. While Haruka acts silly sometimes, her schoolwork is good enough to teach Yuu. She is good at cooking, but bad at drawing. Yuu likes to call her "S.B.J.K." (Shitto Bukai Joshi Kousei, which means "deeply jealous high school girl"), and Kotone tends to call her "Harupoppo." She is always pleased to find yuri couples. (Source: MyAnimeList)
