An exorcist, though still inexperienced. His goal is to exorcise Hanako himself. He comes to the toilet after school to watch over Hanako and ensure he doesn't cause trouble. Personality: A hot-blooded, straightforward, and chivalrous boy with a strong sense of justice. Though clumsy, he is a pure-hearted hard worker.
