In New Lone Light City, memories can be traded, tampered with, or even completely erased. Number 734, a blank person called "Zero", lives a numb life day after day with no past and no future.
However, a bloody dream that does not belong to him drags him into the abyss like a ghost. In order to find the answer to "Who am I?", He stepped into the neon shadows of downtown, and every step was accompanied by a fatal pursuit and the resurrection of dusty memories. He is pursued by a woman who hates him, and who helps him is a ghost hidden in the data stream.
