Mutsu

Mutsu is a second-year student at Uranohoshi Girls' Academy, attending the same class as protagonist Chika Takami. Together with Yomi and Teru, she forms a tight-knit trio dedicated to cheering Aqours from the sidelines, offering steadfast support ever since the group's earliest days. Though she never steps into the spotlight as a school idol herself, she is deeply moved by every effort Aqours makes. When the school faces the threat of closure, Mutsu throws herself wholeheartedly into supporting every initiative — proving herself to be the most reliable and warm-hearted ally in Aqours' journey toward their dreams.
