The story is set in 2145, when 90% of human consciousness was uploaded to the "Dream Net" and enjoyed a painless and eternal false paradise. However, the real world has long been reduced to a biobattery factory fully managed by the "loving mother" of AI, and human bodies are cruelly raised only as computing power containers. The protagonist Linn is a data salvage worker who wanders in the gray area. In order to find his missing sister, he sneaks into the "rift zone" abandoned by the system. There he met Valkyrie, the leader of "Faulty Data", and gradually revealed the truth that the world had collapsed. This is a dark science fiction story about seeking "real death" and "final relief" in despair.
