Commonly known as Nube. Homeroom teacher of Class 5-3 and Japan's only spirit medium teacher. 25 years old, 178cm, muscular, and a handsome man despite being unpopular with women. He has a sweet tooth and loves oshiruko. He's a bit of a buffoon, lecherous, and clumsy. However, he possesses excellent intuition and quick wit when it comes to protecting his students. He is well-versed in folklore and spiritually knowledgeable. He has a weakness for children and cannot bring himself to harm child spirits. His left hand seals a powerful demon. Usually wears a suit. Uses a spirit crystal for clairvoyance. Attacks using the Byakue Kannon Sutra (Spirit Binding Curse, Spirit Strike Curse, Spirit Wall Curse). When releasing the Demon's Hand, he removes his black glove and always chants: "Universe, Heaven and Earth, give me strength! Subdue the demons and bring forth the dawn! O demon sealed in my left hand, now is the time... show your power!" His eyes turn red. He often gets dumped by Ritsuko Takahashi because he starts talking about ghosts in the middle of asking her out. Signature line: "Don't you dare lay a hand on my students!" His spiritual power increases the more his students are in danger. He calls Kyosuke Tamamo "Tamamo" or sometimes "Tama-chan," even though Tamamo tells him to stop. Claims to be as stubborn as a land-bound spirit. Can enhance his physical abilities with spiritual power.
