In "The Mystery of Mamo", it is mentioned that Zenigata has a daughter named Toshiko, but to date this has never been mentioned since the film. In an episode of "Lupin III Part II", Zenigata is asked if he has any family, to which he replies "not yet". He's unable to settle down because of his eternal pursuit, and although he sometimes longs for female company (such as a reporter Maria in "Crisis in Tokyo", who compares him to her father) his single-minded attitude regarding the capture of Lupin leaves no personal time available. In the 2012 series "", Fujiko is seen performing sexual favors to an apparently willing Zenigata in order to avoid jail time. The Pioneer dub of the second anime series inserted Zenigata comically making continuous references to his mother.
