Ginoza grew up in a household overshadowed by his father, Tomomi Masaoka, who was an Enforcer in the PSB after being deemed a latent criminal. Ginoza’s relationship with his father was strained, as he resented Masaoka for succumbing to the system’s judgment and believed his demotion brought shame to their family. This led Ginoza to adopt a rigid and uncompromising adherence to the rules of the Sybil System in an effort to distinguish himself and avoid a similar fate.

As an Inspector, Ginoza partnered with Shinya Kogami, a skilled but rebellious officer. Kogami’s demotion to Enforcer after the Specimen Case further reinforced Ginoza’s belief in strictly adhering to the system to maintain his Psycho-Pass. However, his rigid worldview was challenged by his new partner, Akane Tsunemori, whose moral clarity and empathetic approach contrasted sharply with his own. Ginoza’s descent into latent criminal status occurred after witnessing the violent death of his father during the pursuit of Shogo Makishima, a tragedy that caused his Psycho-Pass to rise to an unacceptable level. His demotion to Enforcer forced him to confront his past, re-evaluate his beliefs, and eventually reconcile with his father’s legacy.

Ginoza is a tall, slender man with a professional and polished appearance. He has black hair styled neatly, reflecting his serious and disciplined personality. His signature accessory is a pair of rectangular glasses, which symbolize his initial adherence to the Sybil System and his attempt to distance himself from the stigma of latent criminality.

After his demotion to Enforcer, Ginoza adopts a more rugged appearance, including longer hair tied back in a ponytail and the absence of his glasses. This change reflects his transformation and acceptance of his new identity.

Ginoza is initially portrayed as cold, pragmatic, and by-the-book, prioritizing efficiency and adherence to the Sybil System over personal connections. His strict demeanor often leads to tension with his colleagues, particularly Kogami and Akane, whom he views as too emotionally driven and idealistic.

Despite his outward stoicism, Ginoza harbors deep-seated insecurities and unresolved issues with his father, which manifest in his harsh judgment of latent criminals and Enforcers. His journey from Inspector to Enforcer forces him to confront these issues and embrace a more empathetic and open-minded perspective.

As a Special Investigator in Psycho-Pass 3, Ginoza displays a calmer and more composed demeanor, reflecting his growth and newfound acceptance of his role within the system.
