Description
Emerging anonymously in Shigeru Mizuki's 1960 rental manga "The Boarding House" as a minion of Dracula IV, this character evolved into the named Nezumi-Otoko in later stories like "An Odd Fellow." His name employs the kanji 根頭見 (root-head-look), reflecting his appearance; his true name was revealed as Peke Peke within the Jigoku Arc. He earned the nickname "BiBiBi no Nezumi-Otoko" from the sound of face-slapping or his whisker vibrations during money-making schemes.
Nezumi-Otoko possesses a humanoid form marked by prominent rodent-like features: whiskers, buck teeth, and a patch of head hair. He typically wears a long brown cloak over a loincloth. His skin shows ringworms and scabs due to notorious poor hygiene; he claims never to have bathed, though adaptations contradict this. His potent breath can incapacitate opponents, and his body hosts unique diseases evolved specifically within him.
Greed and self-interest define his character. He obsessively pursues wealth through schemes such as impersonating Kitarō's agent, selling fraudulent services as a "yōkai researcher," or conning humans. He frequently betrays allies like Kitarō when bribed or threatened, yet consistently returns when advantageous. Despite this, he demonstrates occasional loyalty, risking his life to save Kitarō from Wanyūdō or refusing betrayal under duress during the Western Yōkai Corps incident. He harbors a deep fear of cats and cat-like yōkai, particularly Neko-Musume, whom he considers his natural enemy.
His half-human, half-yōkai heritage remains ambiguous. Conflicting accounts exist: one describes his mysterious birth as a human baby on a rat-inhabited island, while the Jigoku Arc suggests he originates from a dimension between the human and spirit worlds where "Nezumi-Otoko" is a species designation. He briefly believed he had a mother named Mami and a sister (Nezumi-Onna), though Mami was later revealed as an impostor. His backstory includes centuries of mistreatment by humans and yōkai for being a half-breed, contributing to his mischievous nature.
His combat relies on unorthodox tactics: foul breath, flatulence attacks powerful enough for propulsion, and slaps. He adapts readily to human technology, driving vehicles and using devices like cell phones, skills impressing other yōkai. He claims academic credentials from "Bizarre University, Filth Department" with a degree in "Lazy Studies," though their validity is dubious.
Key story arcs explore his complexity. In the Jigoku Arc, he temporarily abandoned a reunion with his supposed mother to aid Kitarō's journey through hell. He once assisted Shinigami with assisted suicides, claiming this role "warmed his evil heart." Animated adaptations soften his villainy compared to the manga; the third anime depicts consistent cooperation with Kitarō to impress Yumeko, while the fifth anime introduces mutual romantic interests, though these typically end tragically within single episodes. His death in two instances (episode #26 of the second anime and episode #3 of the fourth anime) provoked mixed grief among yōkai, highlighting his ambiguous social standing.
Shigeru Mizuki considered Nezumi-Otoko his favorite character, stating the series "wouldn't unfold steadily" without him. He served as Mizuki's mouthpiece for social satire, embodying themes of poverty and opportunistic survival, contrasting Kitarō's altruism. Mizuki based the character partially on Umeda Etaro, a colleague known for failed get-rich-quick schemes.
