Movie
Description
Nezumi-Otoko is a half-human, half-yōkai male with a rat-like face, long whiskers, buck teeth, and a gaunt body usually wrapped in a single tattered robe. He is famously unhygienic, claiming to have not bathed in centuries, and is often covered in welts and filth. His appearance reflects his nature as a scavenger and opportunist who drifts between the human and yōkai worlds.

His personality is defined by greed, laziness, and self-interest. He is a chronic schemer who constantly seeks easy money or advantage, and he will switch allegiances without hesitation if he believes a stronger party can benefit him. Despite this, he is not purely evil; he operates as a trickster and a coward, often running from danger rather than facing it. His motivations are almost always material gain, food, or survival, and he rarely acts out of genuine concern for others.

In the film Gegege no Kitarō: Saikyō Yōkai Gundan! Nihon Jōriku!!, Nezumi-Otoko is initially part of Kitarō’s group but quickly panics when the Chinese yōkai army attacks. He attempts to flee and later tries to switch sides, hoping to profit from the conflict. However, the Chinese leader, Chi, sees through his betrayal and traps him in a storage container. Later, while imprisoned, Nezumi-Otoko manages to escape and inadvertently steals not only the enchanted cloths that had turned captured yōkai into bolts of fabric but also the crucial medicine used to create those cloths. When Chi releases a deadly poison cloud that threatens to annihilate the Japanese yōkai, the medicine spills from Nezumi-Otoko’s stolen jug, weakening the poison and giving Kitarō an opening to defeat it. Thus, his cowardly opportunism accidentally turns him into an unwitting hero.

His key relationships revolve around Kitarō, whom he calls a friend but frequently betrays. He has a particularly antagonistic relationship with Neko-Musume, who despises his dishonesty and foul habits. Kitarō tolerates him as a “bad friend” and often rescues him from his own misdeeds. Nezumi-Otoko’s role in the story is that of a comic-relief side character whose unreliability creates tension but whose accidental contributions sometimes save the day.

Development in the film is minimal; he does not undergo a meaningful change of heart. Instead, he remains a self-serving figure who is lucky enough to end up on the right side through happenstance. His notable abilities include no special combat powers, but he is skilled at lying, sneaking, and exploiting situations. He is also a fast talker and can sometimes use his knowledge of the yōkai world to identify useful items, as shown when he instinctively steals the medicine. Overall, Nezumi-Otoko embodies the chaotic and morally ambiguous element of Kitarō’s world, always hovering between hindrance and help.
