Spooky Kitarō focuses on the young Kitarō—the last survivor of the Ghost Tribe—and his adventures with other ghouls and strange creatures of Japanese mythology. Along with: the remains of his father, Medama-Oyaji (a mummified Ghost tribesman reincarnated to inhabit his old eyeball); Nezumi-Otoko (the rat-man); Neko-Musume (the cat-girl); and a host of other folkloric creatures, Kitarō strives to unite the worlds of humans and Yōkai.
