Hanabishi Fusai no Taimajou

Suzuko is a duke's daughter whose hobby is collecting ghost stories. One day, while consulting a client about a strange phenomenon, she meets a young merchant named Takafuyu Hanabishi. He is possessed by the spirit of a noblewoman dressed in a twelve-layered kimono, and Suzuko witnesses the spirit eating the spirit of a geisha who had been possessing the client.
