Description
Detective Yamitaro Ankokuji serves as police inspector and warden of the Atami police station, dedicated to maintaining regional peace. Despite a family history deeply rooted in generations of yakuza involvement, he chose the path of law enforcement. Ankokuji cuts an intimidating figure: tall and broad-shouldered, typically clad in a trench coat and fedora. His shoulder-length messy black hair, thick sideburns, and black eyes contribute to a gangster-like appearance noted by characters such as Shiro Kabuto.

Personality-wise, Ankokuji takes a pragmatic approach to law enforcement. He prioritizes peacekeeping over rigid black-and-white judgments, evidenced by his eventual permission for Koji Kabuto and the Photon Power Laboratory to combat Mechanical Beasts despite initial reservations. He exhibits frustration when faced with ambiguous language or hidden meanings. Professionally, he relies on sharp observation and intuition, accurately identifying threats like assassination or kidnapping plots against Koji. His combat prowess includes proficiency with firearms—from conventional pistols to chemical-based weapons—allowing him to dual-wield against multiple foes, complemented by martial arts training in boxing and karate.

Ankokuji first appears investigating disappearances around the Kabuto household, leading him to act as bodyguard for Dr. Juzo Kabuto. During an attack by Baron Ashura, he assists Juzo in escaping Iron Mask pursuers and witnesses Juzo's fatal injuries. He later observes Mazinger Z's capabilities but is impersonated by Baron Ashura, who frames Koji for Atami's destruction. The real Ankokuji, recovering at the Kurogane House, subsequently joins the counterattack against Dr. Hell's forces.

His story expands during a mission to Germany, where he infiltrates the Ashura Corps to rescue Shiro Kabuto. There, he encounters and develops an attraction to Gamia Q3, a reprogrammed android. After surviving an energy surge in her containment room—where he is initially presumed dead—both resurface with aid from Kenzo Kabuto. Gamia Q3's distrust of Kenzo results in their imprisonment at the Photon Power Laboratory until Viscount Pygman attacks. During this confrontation, Pygman injures Ankokuji with a decay-inducing chemical, prompting Pygman's true form revelation. Ankokuji and Gamia Q3 then witness Mazinger Z's climactic battle against the emerging Mycenae Empire.

Throughout these events, Ankokuji remains a supporting ally to the protagonists, balancing investigative duties with combat engagements against Dr. Hell's forces. His relationship with Gamia Q3 adds a personal dimension, though their ultimate fate remains unresolved after the Mycenae Empire's rise.
