Ark IX

A vast wall divides the world in an effort to contain the Dark Mist, while displaced people shelter in artificial cities known as Arks. Within the ninth of these refuges, Enishi Shido works as a private detective, using his unusual skills to investigate the problems hidden beneath the city's protected surface.

A request to apprehend a burglar initially appears straightforward. Pursuing the target, however, draws Enishi into a conspiracy far larger than the original offense suggests. Completing the assignment now requires discovering what lies behind it and questioning the assumptions that made the case seem so simple.
