Mimi Kagari

Mimi Kagari is a mysterious student with long pink hair and purple eyes who suddenly appears before Sheena Totsuki, covered in blood after returning from the battlefield. Despite her youthful appearance and cheerful, child-like behavior, she possesses an extraordinary combat ability and is rumored to be the "secret weapon" of the school, capable of recovering even from fatal wounds. Upon transferring to Class 14, Mimi becomes Sheena’s roommate and partner. She shows an intense, unhesitating affection for Sheena, which brings warmth to their otherwise bleak, death-filled daily life. Her presence challenges the status quo of the academy, as her wild, affectionate nature clashes with the cold expectations of a weapon-in-training, yet she remains devoted to spending every moment by Sheena's side.
