Ibuki Hinata

Ibuki Hinata is a fellow second-year student, her class representative and Ui Nakatsugawa's childhoood best friend. Besides her academic excellence and status on the student council, she is also an active member of the archery club, having practiced the sport since middle school. Her first acquaintance with Kazuma Hoshino is a suspicious and disparaging one; much to her own confusion, his kindness rubs off and she ultimately develops a soft-spot for him. Although Ibuki can be tough and difficult, she succumbs to her feelings and can be particularly tender and shy. Ibuki has light purple hair ...

At first, Ibuki is harsh to Kazuma Hoshino, but she opened her soft-side for her after he showed that he is a good guy. She is also a "tsundere", because she doesn't show her true feelings for Kazuma.
