An imaginary future city no.6 Fanfic, the CP is Shuyuan.
Onmyoji Mouse, who appears to be a detective, is a remnant of the "Uta Clan" of a family of demon slayers protected by Queen Eliuriaz of the Peak. The identity of Shion, who is 21 years old but only looks like a 17-year-old, is confusing. The conspiracy of the undead clown, the fall of The game in the village, the warning of the coming of death, the mysterious and angry Kirin, the sealed nine-tailed fox, the hatred between Suzaku and Mei, the forbidden love between Nekomata and Onmyoji, can Mouse and Shion overcome many difficulties and learn the truth of the matter?
