In Xinhai City, a future city shrouded in a huge energy dome, the technology giant "Eternal Mind" maintains false peace by tampering with memories. A man code-named "Zero" woke up from the underground black market of memories. His mind was blank, but he had special skills.
In order to regain his identity, he reached a deal with the mysterious and glamorous data broker "Frimson Fox", but step by step he was involved in a shocking conspiracy called "The Cradle". What pursues him is an old enemy from the past; what guides him are memory fragments called "reverberations" that keep flashing in his mind.
When the truth was peeled back layer by layer, he discovered that he was actually the creator of this steel cage. How should he choose between past sins and today's redemption, false happiness and painful reality? When the final secret points to the only partner fighting alongside him, who should he point to when he pulls the trigger?
This is a story about redefining "self" on the ruins of memory.
