The story happened at the end of the Edo period. The story of demon slayer
Haisuke Yamaoka (voiced by Guan Toshihiko) could have inherited his ancestral business, but he aspired to become a famous writer because of his obsession with anecdotes. I want to collect all kinds of strange stories by traveling around, and write them into "Hundred Stories of Alleys" to realize my dream of being a writer.
Haisuke met a mysterious trio on a rainy night: Mr. Imitation Teacher Er (voiced by Wakamoto), Yuyuki Mr. Shiyoushi (voiced by Takasho Nakao) and the puppet master Miss Ayin (voiced by Sha Miao Kobayashi), the three of them have mysterious whereabouts, and supernatural events will happen wherever the three of them appear, which makes Baijie interested. By chance, Baijie followed the three of them to the dark world, and thus witnessed many strange events. Baijie was very excited, because these stories could become the material of "Street Talking Hundred Stories" he wanted to write.
