Technology is developing year by year, and people are no longer satisfied with surviving for just 100 years. After gradual exploration, people discovered minerals that can extend life, but large-scale dismantling of ores has worsened the climate and ecology. A large number of mutations caused by radiation began to appear in various places. People refer to these places where mutations occur as "dungeons", and adverse mutations caused by radiation are called "alienated bodies". A few people have favorable mutations due to radiation and develop special skills, which are called "skills", and people with "skills" are called "power users". There are also a very small number of "alienated bodies" with the ability to think in the dungeon, called "boss", and some "boss" with "skills" are called "lords".
