Humanity has entered the interstellar age, and high technological civilization has allowed robots to replace most of the basic work. People have a lot of free time in their lives, and some lunatics begin to dream of higher civilizations. They invented the "Scavenger". The mission of the "Scavenger" is to clean up some inappropriate "garbage" and prevent them from polluting the civilization of higher organisms. No one likes to be controlled by others, so an organization was born that specializes in studying and eliminating "scavengers"...
Intention: Nanke's dream will eventually come true
