Walk past a shuttered mansion in old Kyoto, the kind whose garden has gone to weeds and whose sliding doors have rotted off their tracks, and folklore says you might still find a light in one room. Inside, a woman in faded court robes sits before a mirror, blackening her teeth as court fashion demanded centuries ago. No one is coming to see her. She grooms herself anyway.
What does it look like?
Toriyama Sekien drew Ao-nyobo for his 1779 catalogue Konjaku Gazu Zoku Hyakki (今昔画図続百鬼, "The Illustrated Hundred Demons from the Present and the Past, Continued"), and the print is quieter than most of his monsters. She appears as a woman in the multi-layered robes of a Heian-style lady-in-waiting, seen from behind as she peers into a mirror. Sekien's short caption gives her teeth blackened in the ohaguro style. Her brows, it says, are shaggy and overgrown (bōbō mayu). Blackened teeth were a standard fashion for women of rank, kept up here long after the household around her has fallen apart.
A lady-in-waiting who never received a promotion
The name is a small joke buried in classical vocabulary. In old court usage, ao-nyōbō was a real term for a young, low-ranking lady-in-waiting. Here ao means "green" in the sense of inexperienced. Sekien took an ordinary bureaucratic label for "the new girl on staff" and gave it a second life as a ghost who is still, after everything, waiting for her career at court to go somewhere.
That reading fits the picture. She isn't a fearsome apparition reaching for a victim. Sekien says only that she watches the people who come by. She is stuck at her toilette, endlessly rehearsing the self-presentation a court lady owed to a household that no longer exists to see it.
Habits of an empty house
Ao-nyobo's stories, such as they are, stay small and domestic. She doesn't chase travelers or curse a bloodline. She occupies abandoned aristocratic residences — the kind of once-grand yashiki left to rot after a family's fortunes collapsed, a common enough sight as Kyoto's court nobility lost income and relevance across the medieval and early modern centuries — and continues her routine there: dressing, blackening her teeth, peering into her mirror, as if a lord might still walk through the gate and expect to find the household properly turned out. The dread in the image comes less from violence than from repetition: a ritual of readiness performed for a guest who is centuries overdue.
Where it comes from
Sekien's later catalogues often work by taking a real word or social type and pushing it slightly askew into the supernatural. Ao-nyobo reads as that kind of literary invention rather than village belief. The picture itself was not new. Older Hyakki Yagyō Emaki scrolls already showed a court-lady monster blackening her teeth at a mirror. Sekien probably gave that figure its name. The joke depends on knowing court vocabulary: an audience that recognized ao-nyōbō as "junior attendant" would catch that Sekien had turned a real rank into a haunting, using the abandoned mansion as a stand-in for a court whose glory had already drained out of it by his own era. Edo-period readers, several centuries removed from the Heian aristocracy at its height, would have found real pathos in a ghost still performing the manners of a world that had already ended.

Ao-nyobo today
She has stayed a minor figure, cited mostly in yokai reference books alongside Sekien's other prints of solitary women in decayed settings, without a signature legend or a battle scene that would give her a modern foothold in games or anime. What survives is the print and its quiet joke: a woman who never made it past junior rank, still keeping herself presentable in a house nobody visits anymore.
