Ao Nyobo

Ao Nyobo are a type of spirit found in Japanese mythology, part of the massive family known as yokai. They are distinct creatures in their own right, but share a similar pattern to many female monsters in mythology. Having once been human but transformed into monstrous creatures due to greed and vanity, Ao Nyobo are depicted commonly in Japanese folk art and folk tales but are less known outside of their local folklore (unlike the infamous kitsune or oni).

History
Ao Nyobo are man-eating spirits of poverty and misfortune that haunts abandoned homes, often large ogre-like creatures they are always female and forever applying makeup and dressing in fine wares but visibly rotting and decaying. They will hunt down and devour anyone that happens upon them and then return to their eternal fussing, as if trying to keep beauty that has long faded into nothingness.
