In the cyber city "New Kyoto" where neon lights and acid rain intersect, death is not the end. As long as the price is enough, memory can become an eternal "echo".
K, a top master who sells memory submersible technology in the abyss, his job is to sneak into the brains of the dead and dig out deeply buried secrets. He is calm and efficient, like an emotionless machine, just trying to redeem the past that can burn his soul in every dive.
A mysterious commission from the upper sky area dragged him into an unprecedented whirlpool. The target is the memory of the technological giant Atlas, but deep in the tomb-like memory, what awaits him is not cold data, but a living, malicious digital ghost.
This ghost is Atlas's undying ambition. It parasitizes in K's mind, peeks into his most vulnerable scars, tempts him, and gives him strength, trying to turn him into his own body when he returns to the world.
From being hunted prey to a hunter living in symbiosis with the devil, K must uncover the "Pure Land" plan that can subvert the survival of mankind before his consciousness is completely swallowed up. In the deep sea of memory, he not only has to fight against a madman who wants to become a god, but also faces the self he has been avoiding.
When human nature can be encoded, when eternal life becomes a curse, is the final salvation to forget, or to remember everything?
