Lot DR1

The city where the 16-year-old boy Kitch lives has experienced a devastating disaster, with more than half of the population missing and dead. The sky is full of drones. The strange thing is that these drones are autonomous. They are out of human control and fight against humans. In the process of searching for his father, the male protagonist accidentally learned about the density of a certain substance that can be implanted in the human body. After a series of encounters, he took his drone and joined an organization called DR1, and then used human-controlled drones to fight drones in various ways.
