In this era where alien beasts have descended on the world for fifty years, humans have relied on the discovered and awakened "original power" and the various strange "superpowers" derived from it to defend the giant steel cities from the ferocious offensive of alien beasts and retain the fire of civilization. Everyone has Yuan Power hidden in their body, which will naturally awaken between the ages of sixteen and eighteen. The type and intensity of the awakened power directly determines a person's future.
