Sentouin XX

A rank-and-file member of the Monster Corps. After the corps' officers were defeated, she refused to remain in the floating city to participate in staged battles, making her the sole survivor among those who insisted on continuing the fight on the ground. She ordinarily conceals herself in Hibiki Sakurama's room while disguised as a human girl. Known for her haughty attitude and decisive actions, she firmly believes that combatants must remain loyal to their superiors and harbors hostility toward both humans and traitors. As the story unfolds, she eventually assumes a position as a director of the Monster Protection Association.
