Bendy and the Imp's Survival

I.M.P doesn't usually take requests from clients that don't actually show up to the office. This client seems relentless, however, and after three letters Blitzo finally gives in. They go in, search the studio their mark is supposed to be in-and Moxxie suddenly vanishes into thin air. There's odd clues that point to the ink staining the walls as the culprit, but otherwise the remaining team members of I.M.P seem to hit nothing but dead ends...And every minute they waste is a minute Moxxie has to fight to live through.
