After resolving to hunt down the final member of the Camerata, Royce Bracket, and then escape the city, Red and her companion find themselves traveling back through the starting portion of the game which has now been "Processed" into a blocky, white facsimile of its original form.
After defeating Royce, leaving him trapped inside the Transistor-world, Red is transported back into Cloudbank, where she begins the task of rebuilding Cloudbank's Processed areas.
