Within the domed city of Romdo lies one of the last human civilizations on Earth. Thousands of years ago, a global ecological catastrophe doomed the planet; now, life outside these domes is virtually impossible. To expedite mankind's recovery, "AutoReivs," humanoid-like robots, have been created to assist people in their day-to-day lives. However, AutoReivs have begun contracting an enigmatic disease called the "Cogito Virus", which grants them self-awareness. Re-l Mayer, the granddaughter of Romdo's ruler, is assigned to investigate this phenomenon alongside her AutoReiv partner, Iggy. But what begins as a routine investigation quickly spirals into a conspiracy as Re-l is confronted by humanity's darkest sins. Elsewhere in Romdo, an AutoReiv specialist by the name of Vincent Law must also face his demons when surreal events begin occurring around him. Re-l, Iggy, Vincent, and the child AutoReiv named Pino will form an unlikely faction as they struggle to uncover Romdo's mysteries and discover the true purpose of the mythical beings called "Proxies." Sometime in the distant future, humanity has managed to survive, but only in isolated cities and through the use of cloning and robotic servants called Autoraves. Life in the cities is strictly controlled by management dedicated to preserving their 'utopian' way of life. But something is causing the Autoraves to become independent and is driving them to seek to escape the city.
