Sayuri Osanada

Sayuri Osanada is an Aomori High student who looks like an elementary schooler but serves as the school's Bancho and strongest fighter. She originally targeted Rokudou out of resentment for his sudden popularity with girls, but her feelings shifted to love after seeing his abilities firsthand. This connection drove her to leave her life as a delinquent behind and reintegrate into the student body, where she now uses her influence to help protect Rokudou’s peaceful way of life.
