At the end of the 22nd century, everyone's every move is quantified into points by the super AI "Rapp". Luo Xi, who fell to the D position, thought it was just an ordinary decline, but during a memorial ceremony, he accidentally witnessed "the echo of a deceased person" asking for help.
Since then, he has been involved in another side of the world: the prejudice of digital integrals, the lies behind the echoes, the rewritten reality, and the Rapp who is regarded as a god.
In the shadows, someone reached out to him—and the owner of those hands might not be considered "human" at all.
