When Nezumi-Otoko brings three members of a Diamond Syndicate, he called and crystallizes one of them, but is stopped soon enough. When he hears that he can eat more human souls that he can now, he strikes a deal with them. They bring him more and more humans, where he desires for even more and grows impatient.

He is an old friend of Konaki-Jijii's and Kitarō asks him to power the Phantom Train so that he can take Mika and Kenta Miura to see their father one last time in Yomi. Wanyūdō asks for something in return because it will cost him a year's worth of yōkai energy to do so. Though Kitarō has no money, Wanyūdō agrees to pay as long as he helps him with a problem he refuses to divulge until after the job is done.
At the end of the film, Konaki-Jijii brings the depowered Wanyūdō to the GeGeGe House and makes his request: for Kitarō to mend his relationship with his wife Rokuro-Kubi. They are seen dancing together during the dance scene at the start of the ending credits.

He is said to guard the gates of Hell and to wander back and forth along the road between this world and the underworld, scaring townsfolk as he passes and stealing the souls of anyone who gets too close in order to bring them to Hell with him.
