Background: Earth History: The earth suffered a natural disaster in 2020. Countless gaps opened in many places, mostly in the northern hemisphere. Countless mutant beasts and monsters crawled out, accompanied by invisible alien spirits. They burned, killed, hunted, and took away human bodies. Human beings were helpless, but this was not permanent. Human beings fought hard despite countless casualties. Human potential is unlimited. Over the course of hundreds of years, humankind's technology and capabilities have been greatly improved. Killing mutant beasts and alien souls is as common as eating. Humanity is no longer the one being suppressed. Humanity has always adhered to the rule that those who are not our own race must have different opinions, and rejects all outsiders.
