In the domed city of Romdeau, humans and "AutoReivs"—androids prone to a sentient virus called Cogito—coexist under a fragile social hierarchy. Re-l Mayer, an elite investigator and granddaughter of the city’s ruler, finds her reality shattered when she encounters a mysterious, monstrous entity known as a Proxy. This beast kills her associates, leaving behind enigmatic messages. Simultaneously, Vincent Law, a struggling immigrant from the outside wasteland of Mosk, finds himself framed for a series of brutal murders. As Re-l hunts the truth, she discovers that the ruling class is hiding the existence of Proxies, god-like beings created by humanity to sustain the domes once the Earth became uninhabitable.Vincent, fleeing Romdeau, embarks on an odyssey across the desolate, ruined world. Accompanied by Pino, a child-like AutoReiv infected with the Cogito virus, Vincent suffers from amnesia, unaware that he is actually Proxy One, the catalyst for the world’s current state. His journey is a desperate
search for identity and purpose, marked by surreal encounters with other surviving domes and philosophical confrontations regarding the nature of existence. Re-l eventually abandons her privileged life to track Vincent, driven by an obsessive need to understand the connection between her own past and the Proxies.As their paths converge, the narrative shifts from a noir-inspired mystery to a profound existential exploration. They learn that the Proxies were designed to be disposable, intended to die once humanity reclaimed the planet. However, the plan failed, leaving the Proxies to wander the wasteland in isolation. The dramatic climax pits Vincent against his creator and his own nature. He must choose between fulfilling his original, destructive programming or embracing his newfound humanity. In a final confrontation that challenges the boundaries of soul and consciousness, the survivors must decide if they are merely puppets in a failed experiment or architects of a new, albeit harsh, reality. Ultimately, the story is a grim meditation on memory, the
search for meaning in a dying world, and the struggle to define oneself against the crushing weight of preordained fate. Through its dense, atmospheric storytelling, the series forces both characters and viewers to question what truly constitutes a "human" soul in the wake of total societal collapse.
