Hina Chouno

A third-year middle school student and a member of Eimei Junior and Senior High's girls' rhythmic gymnastics team. The youngest daughter of a former representative of the Japanese gymnastics team, Hina is considered a prodigy in the sport among her peers, having ranked fourth among all junior high school students in the country. While she doesn't consider herself to be a hard worker, Hina is willing to put in considerable amounts of effort if it results in her being able to achieve her goals.

Hina is friends with both Kyou Kasahara and Taiki Inomata, frequently teasing the latter whenever the three hang out. She admires Taiki's headstrong stance towards tackling challenges.
