TV Special
Description
Inspector Koichi Zenigata, a dedicated Interpol officer from Japan, began his career with the Tokyo Metropolitan Police pursuing Fujiko Mine and her partner. This chase brought him to New York, where he first encountered Arsène Lupin III. The master thief's skills and defiance inspired Zenigata to dedicate his life to capturing Lupin, leading him to join Interpol specifically for this mission. He is a descendant of the famed detective Zenigata Heiji, modernizing his ancestor's coin-throwing technique into his signature handcuff-throwing skill.

Zenigata exhibits intense dedication to justice and an obsessive focus on capturing Lupin. Highly respected within Interpol for his expertise in apprehending criminals and identifying security weaknesses, he has independently captured numerous gangs and felons. However, this single-minded pursuit often manifests as impulsive actions, leading to perceptions of overzealousness. He staunchly resists bribery and adheres to a strong, old-fashioned moral code, causing friction with superiors over resource allocation or corruption.

The dynamic between Zenigata and Lupin extends beyond simple antagonism. While publicly declaring Lupin his nemesis, Zenigata harbors deep, unacknowledged respect. He fiercely believes only he should capture or kill Lupin, reacting with profound grief—even abandoning his career or isolating himself—when believing Lupin dead, as seen when he retired to a monastery in "The Fuma Conspiracy." Conversely, he becomes frustrated if Lupin remains captured too long. An unwritten understanding exists: neither attempts to kill the other, and they occasionally cooperate against greater threats, with Lupin even avenging attacks on Zenigata.

Zenigata's personal life remains largely unexplored due to his obsession. "The Mystery of Mamo" briefly mentions a daughter, Toshiko, unreferenced elsewhere. He typically denies having family, suggesting isolation. He expresses occasional longing for companionship but cannot sustain relationships, and his living spaces reflect transience, often appearing cluttered. He displays emotional sensitivity, crying readily when Lupin shows him kindness or when relieved Lupin survived apparent death.

Physically robust for his age, Zenigata demonstrates proficiency in judo, karate, and jitte techniques. He is a skilled marksman with a Colt .45, though his iconic weapon remains the handcuffs thrown with uncanny accuracy. His obsession fuels seemingly superhuman feats during chases, like breaking down doors or rapidly regaining consciousness after severe injury upon hearing Lupin's name. He exhibits technical ingenuity, inventing devices like inescapable thumb cuffs ("Zenigetchas"), specialized train links, the "Lupin Catcher" detector, and restraining chains.

In "The Columbus Files" (also known as "Ai no da capo ~Fujiko's Unlucky Days~"), Zenigata relentlessly pursues Lupin during a hunt for the Columbus Egg treasure, involving Fujiko Mine who suffers amnesia after possessing the Columbus Files.

Zenigata's character design evolves across the franchise. He is typically depicted as a middle-aged Japanese man with dark hair—sometimes cropped flat, combed over, or shaved. His most consistent feature is a trench coat, varying in color: orange in Part 1, camel in Part 2 and "The First," light green in Part 3, red in Part 4, and light brown in Part 6. He is slightly taller and more muscular than Lupin, facilitating their occasional mutual disguises.
