The administrative officer of the Disciplinary Committee, supporting the head prefect Hina to the best of her ability. Professional, and serious on the job, shes pretty reliable from what I've heard from the other Gehenna students. Sure shes strict towards the other members but thats expected from a high position in the Gehenna prefect team. Although... there are times where she reveals a bit of her less professional personality. Towards sensei, she often gets arrogant and standoffish. Bickering with sensei whenever they meet. No they don't hate each other (I think). But she cares for the people she knows.
