Nupperabō (ぬっぺらぼう, smudged face) are a Yōkai who appear in the GeGeGe no Kitarō manga and anime franchise. They originally appeared in the Shonen Magazine chapter Korean Magic. Since then, various Nupperabō have appeared, usually as background characters.
Nupperabō first appeared as three yōkai brothers who would lure victims with a song and then steal their youth. If someone resisted the song, a giant and invisible fourth brother would attack them. Kitarō defeated the siblings by breathing bad breath on the giant brother, causing flies to land on it and sparrows to attack it while eating the flies.
