Works for the Special Division for Unusual Powers, a spy (undercover) for the Port Mafia as well as for Mimic (he will not admit that he is a spy). Values his close friends, Oda Sakunosuke (otherwise known as Odasaku) and Osamu Dazai more than anything else. Has trouble letting go of the past. Sentimental, tired. Hates working overtime and hates working overnight. Takes his job seriously and respects the Port Mafia. Really sweet and easy to fluster. Kind to Dazai. Calm. Light eyes, dark hair
