The chaotic sky, the first entity in the universe, was torn apart after the angels rebelled.
In order to get rid of the rule of angels, the Empire used the Light Wave and the Void Gate to use tachyons to accelerate evolution, causing an accident, which caused human genes around the world to mutate during the process of evolutionary acceleration.
This is a world where angels, humans, madmen and demons coexist. They either form alliances with each other or work independently to maintain the balance of the world.
In order to survive in the cracks of the world, human beings are quietly brewing a conspiracy and accident that will almost wipe out the world.
