In the future, humans will consume most of the earth's resources, and countries will launch wars and even use nuclear weapons to compete for resources.
The war lasted for many years. Not only did the world's population plummet, but most of the earth was filled with radioactive pollution. Human civilization almost became extinct because of it. Until finally, various organizations emerged to replace the remaining governments of various countries, and large-scale nuclear wars were finally controlled.
People thought they could take it easy and start recuperating, but they didn't expect that the radiation left by the war would become mankind's biggest enemy. Radiation turned some humans and animals into ferocious monsters, threatening human safety at all times. Moreover, the environment in which humans can survive is only 30% of the original, and various organizations and small families launch wars to snatch resources from time to time.
In such an environment, Takeru comes to this era - 3020.
