Nobuchika Ginoza is a law enforcement officer whose career spans multiple roles within the futuristic justice system. Born on November 21, 2084, to Tomomi Masaoka and Sae Ginoza, his early life was marked by his father's demotion to Enforcer status when he was nine years old. This event fostered a deep-seated resentment toward latent criminals and drove his academic focus on law and criminal justice. He graduated from Nitto Academy's Faculty of Law in 2104 before joining the Ministry of Welfare Public Safety Bureau (MWPSB) as an Inspector in Division 01. During his tenure as Inspector, Ginoza exhibited a rigid, data-driven approach to policing. He maintained emotional distance from Enforcers, referring to them as "hounds" while positioning himself as their "shepherd," stemming from his childhood trauma and the subsequent demotions of both his father and his childhood friend, Shinya Kogami, whom he met in high school after Kogami defended him from bullies. Despite their strained relationship, Ginoza retained loyalty to Kogami, hesitating to shoot him during a critical confrontation. Ginoza's worldview fractured when his father sacrificed himself to save him from a bomb during an operation targeting the criminal Shogo Makishima. Witnessing Masaoka's violent death caused Ginoza's Crime Coefficient to spike to 140, resulting in his demotion to Enforcer in 2113 after a brief rehabilitation period. This transition led to significant physical and psychological changes: he lost his left arm and received a prosthetic similar to his father's, ceased wearing non-corrective glasses he previously used to obscure his resemblance to Masaoka, and adopted a trenchcoat reminiscent of his father's attire. As an Enforcer in Division 01 under his former subordinate Akane Tsunemori, Ginoza developed a protective stance toward colleagues. Though initially critical of Tsunemori's methods, he grew to respect her ethical consistency and detective skills. His operational style evolved to incorporate field experience while retaining analytical rigor. By 2116, he wore his hair in a ponytail and supported Tsunemori's leadership against criticism. In the *Sinners of the System* film trilogy, specifically *Case.1: Crime and Punishment* (set in 2117), Ginoza served as a Special Investigator for the Ministry of Foreign Affairs' Suppressing Action Department. Partnered with Inspector Mika Shimotsuki, he investigated a prison facility where latent criminals were covertly exposed to radioactive waste. During this case, he demonstrated tactical proficiency with his prosthetic arm and prioritized protecting vulnerable individuals, including a child targeted by the corrupt warden. Ginoza's later appearances show him collaborating with Kogami within the Foreign Affairs Operations Department. His personal hobbies include gardening, learned from his grandmother, coin collecting, from his grandfather, and caring for his Siberian husky, Dime—a privilege retained post-demotion due to his dog therapist license. He sleeps six hours nightly, favors bread, and avoids mulukhiyah. A recurring motto—"Fools learn from experience, the wise learn from history"—encapsulates his analytical worldview. This perspective evolved from inflexible adherence to protocol toward a more nuanced understanding of justice, influenced by his father's legacy and his own fall from Inspector status.
