Hinaka Tachibana (立花 日菜佳 Tachibana Hinaka) is the younger of the Tachibana sisters. Her cheerful demeanor makes up for her lack of intelligence like her older sister. She usually hangs around TAKESHI Headquarters to track the Makamou and rarely goes out into the field. She has a crush on Todoroki, but he is usually clueless about her approaches.
