Prior to the beginning of the story, in the 23rd century, the Earth has shattered into billions of pieces which orbit around a central core. In this new world, named Skyland, an evolved form of human has appeared: Seijins, who absorb energy from sunlight and use it to fuel special abilities such as telekinesis, telepathy, mental control, astral projection, energy balls or blasts, and electric rays.
