Imperial College Division 9

The Ninth Department of the Imperial State is a mysterious and dangerous department in the eyes of ordinary people. They specialize in dealing with type 0 incidents that ordinary departments cannot handle: serial killers on rainy nights, headless corpses on the banks of the Thames, skinned men in Leighton Manor... However, for Li Shuyun in Section 9, this is just an ordinary daily life for a group of boring people.
