Idea: a Touhou creepypasta centered around Rumia that would be phrased as an urban legend children from the human village would often hear. The youkai of dusk isn't that active in broad daylight, but when the sun sets, she goes to hunt travelers who get lost in the dark of the night to feast on the darkness of their hearts. It is said that the fear of the dark children usually have comes from the youkai's stalking on every pitch-black corner; however, children are spared solely due to their minds still being pure and holding barely edible darkness to consume. Her childlike appearance would also work as a luring device for inattentive people to approach near her.
