In the neon-soaked metropolis of Cloudbank, a renowned vocalist named Red discovers a murdered man beside an otherworldly blade—the Transistor—wielded by the Camerata, a shadowy faction of city elites. The weapon strips Red of her voice and imprisons it within the sword's luminous core, while simultaneously trapping the consciousness of the slain man inside, granting him the ability to communicate with her from within the blade. As Red pursues the Camerata through the city's streets to reclaim what was taken, an autonomous mechanical force known as the Process descends upon Cloudbank in a devastating assault, revealing that those responsible for Red's suffering have catastrophically lost control of their own creation.
