MottoDo not disturb unless it's task-related.

Senior administrator of the Gehenna Prefect Team and secretary to the head prefect, Hina. Ako is always by Hina's side, assisting her. At first glance, she appears to be kind and good-natured, but she ruthlessly suppresses rule-breakers, showing no mercy. The students of Gehenna often call her "Hina's pet," but she doesn't seem to mind.
