This is making me think of certain… "art" I've seen before.

She's definitely one of the more obscure yokai. My understanding is in Japan she's like their version of Slenderman, but here she's really only known by people with a heavy interest in yokai and urban legends. One piece of media that I know does have her is Fatal Frame 5, where she's a special secret boss ghost you can encounter. Also the devs behind Resident Evil Village outright stated she was one of the major inspirations behind Lady Dimitrescu.
