A former delinquent and Harutora's best friend from school. He is capable of special spirit sensing and has a vast knowledge on onmyodo. He was a victim to the paranormal disaster from two years ago. Harutora's doctor father treated him although the after-effects remained. He realized way before Hokuto that Natsume was the one who conjured her. He enrolled the Onmyo Academy in Tokyo along with Harutora.
SpoilerTwo years prior to the story, it was revealed that he was possessed by the ogre which caused the Spiritual Disaster. Thus in the end he became a half-ogre and now tries to gain control to contain the ogre within himself. The reason he enrolled in Onmyo Academy was to purify the ogre inside him.
