An office worker moonlighting as a detective, his demeanor is that of the quintessential Japanese man. He has an earnest, mild personality and leads his life always thinking of others. He had aspired to become a detective for years, so upon learning of the Alliance's existence, he begged both his wife and employer to let him take on the job. He isn't showy when investigating, focusing instead on thorough, steady analysis. Combined with his personality, however, he's often told he doesn't leave much of an impression.
