In Sekien's explanatory text in the Konjaku Gazu Zoku Hyakki states that there is a story called Otogi Bōko (御伽ばうこ) in which an aged female skeleton would carry a chōchin (lantern) decorated with botan flowers on it and visit the house of a man she loved back when she was still alive, and then cavort with that man. In other words, this refers to "Botan Dōrō" (牡丹燈籠, "The Peony Lantern"), within the collection of writings called Otogi Bōko (伽婢子; 1666) by Asai Ryōi.[1] (The collection was composed as a sort of moral-free version of the Chinese work Jiandeng Xinhua written in 1378 by Qu You.) In the Botan Dōrō, a man named Ogiwara Shinnojō meets a beautiful woman named Yako and they become entangled almost every night, but one night an old person from next door catches a glimpse of it and sees the strange scene of Shinnojō embracing with a skeleton.[2]
