Nobuchika Ginoza is a 28 year old Enforcer working at the MWPSB Unit 1. He is demoted from the rank of Inspector to Enforcer after his Psycho-Pass reading rises to an unacceptable level after witnessing the violent death of his father.

    As an Inspector, Ginoza is very strict when it comes to his job and disallows himself to have emotional bonds with his Enforcers because he believes it will cloud his Psycho-Pass. It is revealed in the anime that his father is Masaoka, a latent criminal and an Enforcer on Ginoza's team. Ginoza's resulting bitterness contributes to his view that Enforcers are less than human, treating them as "dogs" and even calling them so. When Akane joins his team, he warns her against becoming friendly with the Enforcers, though she does so anyway, particularly with Kougami.

    Ginoza appears somewhat adversarial towards Kougami and Masaoka, in particular. As the series progresses it becomes apparent that he views their demotions to Enforcers as personal betrayals, leaving him with feelings of abandonment. Despite his loathing of Masaoka as an Enforcer, Ginoza still subconsciously craves his approval as a father. As a result, the amount of faith Masaoka places in Kougami causes Ginoza to develop feelings of jealousy and inferiority. These emotions, combined with the pressure of the job and the burden of keeping his Psycho-Pass clear, cause Ginoza to become wracked with deep anxiety and insecurities, which contribute to his exhaustion and cause him to fall apart as the series progresses.

    Ironically, Ginoza fears that Akane will go down the same path as the Enforcers, though it is he who stumbles in his job performance and goes the very route he fears for Akane, thus repeating the sins of his father and his friend, Kougami. Due to events which occur in the series, his Psycho-Pass begins to grow cloudy. Despite being told to get treatment, he ignores the advice and focuses only on his work. It is the violent and untimely death of his father, Masaoka, that creates an emotional upheaval in Ginoza's psyche, causing his Crime Coefficient to increase to 140, resulting in him losing his position as Inspector and demoting him to being the very thing he despises, a latent criminal. Ginoza, however, leaves treatment after only two months and, being a detective through and through, returns to the MWPSB as an Enforcer who works under the very trainee he used to supervise, Akane Tsunemori.

    Following his demotion and return, Ginoza is shown to a bit more laid back, shown to smile a bit more and to not be offended by personal questions, especially regarding his father.
