The story begins on a rainy night. The amnesiac private detective **Zero**, relying on his special ability to sneak into and "weave" the memories of others, barely survives at the bottom of the "New Arc City". He is hired by the mysterious Department of Public Safety detective Evelyn Reed to investigate the murder of tech giant Kaito Tanaka. During the investigation, Zero discovered a "Ouroboros" mark in the memory of the deceased. This mark accidentally triggered his own dust-laden memory fragments, suggesting that the case was closely connected with his past.
As the investigation deepened, Zero discovered that Ouroboros belonged to an extremist organization called the "Memory Liberation Front"**. In an abandoned "Dreamland" experience hall, he was awakened to his true identity - he was the leader of the organization **"Dream Weaver"**. His amnesia was caused by the self-formatting program **"Protocol Zero"** launched five years ago to protect a shocking secret. The discovery turns him from investigator to most wanted man, forcing him to go on the run.
