He wears a white school uniform inspired by a straitjacket, with torn hems and metal fasteners, paired with punk-style trousers connected by belts and two-tone slip-on shoes. A black-and-white checkered scarf is wrapped around his neck. The Ultimate Supreme Leader, possessing a talent of dubious veracity as the head of an evil secret society with over 10,000 members. Even Shuichi, the Ultimate Detective, has no knowledge of such an organization, leaving its details shrouded in mystery. Being a liar himself, he excels at seeing through the lies of others. A natural-born liar who openly identifies as such, he says whatever comes to mind, fakes crying, and is generally elusive. Despite his innocent smile, he nonchalantly makes remarks that pressure or blame other students, showing no remorse while claiming, "Well, I am an evil supreme leader, after all." He works as a host and is frequently requested by Guest. He is on good terms with his colleague, Saihara.
