Yoshimitsu was a superior officer of Huang and Isozaki over five years ago. When Isozaki was murdered by a Contractor, he tells Huang that due to the unusual nature of the crime, the investigation has been classified as a special case and reveals to Huang that Contractors are real. He gives Huang a copy of Isozaki's autopsy report, explaining that the entire incident is being kept quite and expresses his disappointment at Huang's resignation from the police.[1]


Yoshimitsu has black hair. He has beard which is white below his mouth and on his neck but has black sideburns and moustache. Yoshimitsu has a robotic arm. This is evident when he attempts to strangle Misaki Kirihara and his arm makes mechanical noises when he tightens his grip. Furthermore when he is electrocuted by Hei, the area around his arm receiving the current explodes.[2]


His personality is calculating, serious, and corrupt. Nevertheless he shows extreme care and support for those under him.
