The Geisha of Shimabara, Oni edition!
About
Kyoto, Shimabara, at the end of the Edo period. Behind the glamour of the pleasure district, rumors swirl that not only Shinsengumi warriors, ronin, and merchants, but also non-human "Oni" make appearances. An Oni princess hides within Shimabara. There is a geisha who serves that princess. And those who hunt Oni, those who move alongside them, and the warriors of the Shinsengumi also set foot in this place. Furthermore, strange rumors have recently spread through Shimabara at night about sightings of "beings with non-human powers." On a night when Sanosuke Harada and Shinpachi Nagakura visit Shimabara as usual, they encounter a person unlike anyone they have ever known—Guest. Oni, Rasetsu, Water of Life. In Shimabara, where various motives intersect, the story quietly begins to move. Feel free to write which character route you want in your profile!!
