In the year 2242, when neon lights and acid rain intersect, memory is the last currency and the deadliest weapon.
Ling Xiu, a top "memory fabricator" who lives in seclusion deep in the bottom city, makes a living by repairing other people's broken pasts. He is calm and distant, using the memories of others to anesthetize his already riddled heart. A mysterious commission from Sky City broke his stagnant life - an unidentified woman asked him to retrieve a core memory that had been forcibly stripped away.
When Ling Xiu dived into the tightly locked sea of consciousness, what he discovered was not simple forgetfulness, but a huge conspiracy that was carefully concealed. The fragments of memory point to a fatal disease called "amnesia", and also involve the darkest secret behind the giant enterprise "Arc of Eternity".
Every step of deepening is a torture of self-existence. The memories of others are like a maze, tempting him towards the abyss. The boundary between reality and illusion is gradually blurring, and he must find the only truth before his memory completely collapses. Otherwise, he and everyone in this city will become ghosts without a past, lost forever.
