Changes occurred in the world, and people's bodies also changed accordingly, gaining different powers, and they were called superpowers. There are also many monsters in the world that cannot be solved with original weapons. Such abilities are divided into innate and acquired abilities. Innate ones are strong, and acquired ones are weak. People have established safe places in various areas, the smaller ones are called shelters, and the larger ones are called guardian cities, and these safe places are all controlled by an organization called the Association of Abilities.
