Inspector Ginzo Nakamori of the Tokyo Metropolitan Police Department relentlessly pursues the phantom thief Kaito Kid. He possesses a fiery, boisterous personality, frequently shouting commands at his officers and losing composure when his best-laid plans unravel. Despite repeated failures to capture Kid, Nakamori maintains extreme confidence in his strategies and publicly vows to arrest the thief. His professional dedication often overshadows time with his daughter, Aoko Nakamori.
In "Lupin III vs. Detective Conan: The Movie," Nakamori leads a police operation to intercept Kaito Kid during a jewel heist. He reacts with shock when the thief employs a real firearm against officers—a violent tactic starkly uncharacteristic of Kid. This anomaly is later revealed as Lupin III impersonating Kid under duress. Following the heist, Nakamori is shown in a state of respite, wearing dark blue pajamas adorned with pink hearts while staying at a traditional Japanese villa.
His involvement in the film centers on establishing Lupin III's impersonation of Kaito Kid and the resulting confusion it sows among law enforcement, adhering strictly to his established character traits without significant development.
