Aonyōbō here is less a creature of a fixed tale than a court lady’s image turned uncanny and circulated as iconography. Sekien paints her as a lady-in-waiting haunting a ruined old palace, exaggerating obsolete rites and cosmetics—ohaguro and painted brows—to give her a ghostly air. In Night Parade scrolls she often appears with ladies’ accoutrements such as curtains, mirrors, and fans, quietly following the procession. The name derives from the social title aonyo (young lady-in-waiting), making the yokai label largely retrospective. While a record of an “aonyo” exists in the Azuma Kagami, identification is cautious, sharing only the appearance of a young court woman. Local lore offers few concrete episodes, and the setting is typically a decayed palace or the parlor of an old house. Despite its creative coloring, this is a leading example of a pictorial yokai that renders the afterimage of court culture as the uncanny.
