Kaii to Otome to Kamikakushi

A city is plagued by a succession of strange occurrences, and a demonic entity is called upon to confront them. Sumireko appears to be nothing more than an unassuming shop clerk, yet she harbors dreams of becoming a novelist and possesses a striking figure that has earned her a handful of devoted admirers. Among them is Adashino, a bookseller with a boyish appearance, who initially seems wrapped in enigma. Before long, however, the true nature of his circumstances comes to light: he and his sister must navigate a series of trials scattered across the city, for only by overcoming them can they secure the passage that will carry them back to their home beyond this world.
