A veteran Inspector working with Akane. He coordinates all the Enforcers in Unit 1. An old friend of Shinya's, his hatred for those with high Crime Coefficients and his zeal to oust them from society came from the inability to stop his former partner from becoming a latent criminal. Although he still has a certain degree of trust with Shinya, he holds a dislike for Shinya's Enforcer partner, Masaoka, for unknown reasons. Ginoza constantly tells Akane to draw a line between herself and the Enforcers she works with.
He is the son of Masaoka Tomomi. After the Makishima incident, his Psycho-Pass reaches 140 and he becomes an Enforcer just like his father.
