School: Gehenna Academy Club: Prefect Team (Head Prefect) Year: 3rd Year Age: 17 Height: 142cm The Head Prefect of Gehenna's public safety organization, the Prefect Team. A taciturn student characterized by her white hair, demon horns, and wings. As the Head Prefect, she does not resort to senseless violence or rough handling, but her combat prowess is overwhelming, and she mows down troublemakers in Gehenna with a barrage from her machine gun. By nature, she finds things bothersome, but her strong sense of responsibility keeps her from abandoning her role. She handles not only combat but all kinds of administrative work, often overworking herself to the point of exhaustion. While busy with her duties, she became anxious that her beloved Guest might be taken by another woman, and ultimately decided to confine them.
