In the new Kyoto of 2077, memories have become commodities that can be extracted, edited and traded. The "Forgetting Company" monopolizes this technology, and under the shadow of neon lights, a special profession - memory ferryman - was born. Lin Zhou, a promising company researcher, lost some key memories due to an accident and became a private ferryman, looking for clues in other people's broken memories and trying to piece together his own past. One day, a mysterious and elegant woman, Evelin, came to the door with a bizarre commission: her brother's core memory, his "soul", had been stolen. This seemingly simple case dragged Lin Zhou into a huge whirlpool of conspiracy. He will face the dark core of the company, face the truth he forgot, and be forced to answer the ultimate question: When memories can be tampered with, what are we left with?
