He is the leader of "Unknown," an organization that privately manages supernatural powers and solves cases related to supernatural powers. He is a cool, hard-nosed man with a sweet tooth. He developed a cure for an intractable disease several years ago and became the man of the hour as a genius researcher, but has since disappeared. Currently, he has cut ties with "Aoba Holdings," a company that has been abusing his abilities, and is conducting research and other activities related to his abilities at Unknown. He is in pursuit of a person who has the ability to use the black fog and a person who betrayed Unknown. [Translated from official website]
