Takayama, Haruka

高山春香

A student at Misato West High School, her large white hair ribbon is her trademark.
Haruka had no friends before meeting Yuu, and consequently, she becomes jealous whenever Yuu gets along with others. Although Haruka sometimes acts silly, she excels in academics and is even capable of teaching Yuu. She is also skilled at cooking, but poor 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.
