An eighteen year old young man in the employment of the city. He is the director of the Hiizumi Life Counseling Office and the only human who works there. He is able to perform "tuning"; an ability that can send back youkai to their world and cut off their connection to the human world. This ability can only be used by his family; the one who succeeds this ability is called oyakume. His hair grows longer whenever he uses his ability. Because of this ability, some of the youkai view the oyakume as murderers. In the manga, Akina reveals that he can use the ability in chapter eight, although (as of volume 4) he tells everyone that he tuned Gin before the start of the series. In the anime, he is able to use "tuning" from the very start.
