Monsters have been sighted around the city of Silys. They seem to come and go without a trace, even in the most crowded spaces. The Anomalous Division of the Silys Investigation Department have sent Adriel and Isari to investigate. Isari has a unique ability that may assist in their search: he can steal faces and slip into the space beyond the walls.
While this ability can be useful, this pair may have been assigned more than they can handle.
