Yoshiwara Higanka fic, because the plot of the game is too painful, I re-wrote it myself, and treated the female protagonist better. The male protagonist is Soichiro, and the second male protagonist is Sakuya. The push-nin, Akito and Shigure can avoid lightning. It can be read simply as a story about Yoshihara's background. In general, it is a rewrite of Yoshihara Higanbana's plot, combining several lines of story to form a whole more complete story.
Intention: The canary will eventually break out of the cage
