The story takes place on an fictional planet in an fictional universe:
The world where the protagonist lives is a highly technologically advanced world, and civilization was almost destroyed after a war. There are only a few peace-loving states left and a few states based on groups with deep pockets and resources. These surviving countries and groups began to unite to reorganize the world and entered a new era: the Star Century.
This is a country where hope and swamp coexist, and a world where developed and backward coexist. Between the world and the gap between civilization and technology are twisted souls. There are always some souls in this lowest-level monster city that shine faint but immortal light to illuminate the place where filth and evil are hidden.
Seemingly cold and cool, he is actually a dark-bellied chameleon sometimes aggressive
