Sign: Virgo
Haruka's most recognizable feature is the big white hair ribbon she always wears. She's a student at Misato West High School.
Before meeting Yuu, Haruka didn't really have friends, and she tends to get jealous when Yuu hangs out with other people. Despite sometimes acting goofy, she's actually a solid student—good enough to help tutor Yuu. She's also a decent cook, though drawing isn't her strong suit.
Yuu has a habit of calling her "S.B.J.K." (short for "Shitto Bukai Joshi Kousei"—basically "deeply jealous high school girl"), while Kotone prefers the nickname "Harupoppo." Haruka's definitely into yuri, and fans often note how happy she gets whenever she spots a potential couple.
