Himuro Karen

Taimanin, Gosha Academy student. Descendant of the Himura clan, a prestigious Taimanin family, she awakened her ninja art early, allowing her to embark on difficult missions as a student to prove her skills. As head of the Student Monitors, she strictly monitors students who disrupt order, skip classes, or are lazy during training sessions.

In order to become a top-tier Taimanin, she never slacks off in her training. Wielding a ninja blade created with her ninja art, she combines the techniques of Ice Art and swordsmanship to freeze and cut down her enemies.
