He is an enforcer under Ginoza Nobuchika and Tsunemori Akane. It is later revealed that he is the latent criminal father of Ginoza. Given a Dominator and being told by Sibyl who to shoot, he lost faith in his role as a detective, and his Psycho-pass grew increasingly cloudier until he was eventually detained as a latent criminal, before becoming an Enforcer. That made him hated by his son. Later on in the series, when he's trying to throw away the bomb that was thrown to Ginoza by Makishima, he died as the bomb exploded in his hands.
