In the city-state of "New Eden" in 2145, humans have realized cloud storage and transfer of consciousness through "consciousness infiltration" technology. As a result, society has been divided into "purists" who refuse the invasion of consciousness, "symbionts" who voluntarily become memory containers, and elite "immortals" whose consciousness has been clouded. Ellie Thorne, a girl from the bottom of the pure, was forced to become a "vessel" due to a terminal illness, and her body was soaked with fragments of the consciousness of the mysterious scientist Keira, giving her abnormal talents and memory pain that was not her own; Marcus Ward, the leader of the "Immortals", maintains a symbiotic balance on the surface, but in fact plans to erase individuality to achieve "absolute unified consciousness"; Ellie's sister Lena, who is being mechanized, and Dr. Howard, who secretly studies rejection, form the core network of this cyberpunk story about consciousness, identity and the nature of human nature.
