He is 188cm tall and a total coward. His trademark is a large, long cowlick. He is a skilled strategist and becomes highly competent when sailor uniforms are involved. He is an easy-to-handle Japanese language homeroom teacher. He speaks casually. He is actually the reincarnation of the Great Onmyoji who lived during the Heian period. He can use exorcism powers, which can nullify the spiritual energy of yokai and even have some effect on the divine power of gods. He has a twin brother.

First person: I (casual, masculine). A golden-haired, blue-eyed god of pestilence. He likes raccoon dogs. A handsome young man standing 174cm tall. He causes misfortune through sorcery. In truth, Haruaki's exorcism powers don't work well on him, and he isn't listed in the Yokai Encyclopedia. The reason is that he is still a "God" and hasn't become a yokai yet. He cannot handle sorcery (divine arts) very well.
