In the "Old Rain City", a cyber city where it rains all year round, memories can be extracted, traded, or even completely stripped away. People are divided into "enjoyers" at the upper level and "forgetters" at the lower level.
The amnesia hunter code-named "Zero" is like a lonely soul in the shadow of the city, making a living by hunting memories. Until one day, a hot memory crystal reflected the childhood he never had.
In order to regain his erased identity, he embarks on a deadly chase. The enchanting intelligence dealer "Liu Li", is it poison or honey? Is the cold white-armored "executive officer" the guardian of order or the executioner of freedom?
When the taboo called "Genesis Seed" was revealed, and when the sleeping girl opened her eyes, Zero discovered that his past was a lie that could overturn the entire world.
In this cage built of memory, what he wants to take back is not only his own name, but also everyone's right to choose.
