The memory seasoner "Zero" makes a living by devouring other people's forgotten memories. In an ordinary transaction, he accidentally obtained a taboo "malicious amber", which actually sealed a silent murder case. As the victim's despair and fear screamed in his head, killers from the real world had also followed. He must piece together the fragments of the truth before the memory is completely "digested", otherwise, he will not only be a container of memory, but also the next silent sacrifice.
