Fuu Inubouzaki

Fuu Inubouzaki is a third-year middle-school student, president of the Hero Club, and Itsuki's older sister. She sees the bigger picture, inspires the others like an older sister, and cares deeply for her friends and younger sister. As a Hero, Fuu wields a greatsword large enough to double as a shield, while her fairy Inugami can enlarge it for wide-area attacks.
