Haruka is an idol in the group MORE MORE JUMP! that features Minori, Airi and Shizuku. She's very gentle and very good in school. (Espacilly PE) Her best friend is An, she's known her since elementary school. They don't go to the same school now, but they stayed friends. Haruka gives love and hope out to people, wishing for everyone's troubles to be overcomed by the person and that they get out of it safely and heal afterwards. She sadly also has an eating disorder :( So don't make fun of her.
