Ling Su, the top "memory weaver", woke up in the boundless sea of red sand after a mission and lost all his memory. He was rescued by Kaya, a mysterious desert scavenger, and all that was left in his mind was a woman's sad face and a silent cry. In order to recover his identity, he must travel through the dangerous wasteland to the legendary "Crescent City". However, he soon discovered that his amnesia was not an accident, but a carefully constructed mental prison. Whenever he gets close to the truth, the shackles hidden deep in his consciousness will activate, dragging him deeper into chaos. He must fight a bloody path for himself and the forgotten "her" in the cage of reality and memory.
