A member of the student council, Haruka is known for her hot-headed and loudmouthed nature. However, she firmly believes in doing what is right and strives to improve the school. She is extremely jealous of Fujino Shizuru and frequently attempts to overshadow her or prove her incompetence as a leader, though these efforts often backfire.
There is an ongoing gag where Haruka consistently uses words and phrases incorrectly, requiring Yukino to correct her constantly. Haruka and Yukino have been friends for a long time, with Yukino greatly admiring and looking up to Haruka, who acts as her protector.
