Short version: By day, a magical girl possesses him as he struggles to survive in the wasteland. By night, he possesses the magical girl in return and causes trouble in another world.
Original version: Wasteland + radiation + mutated monsters + chaos; magic + technology + order + prosperity. Two worlds that should have had nothing to do with each other become connected through the dreams of a man and a woman. Backed by the knowledge and power of a magical, high-tech civilization, Shen Li uses his silver tongue, sharp eyes, and a ball of fire to write his own masterpiece in the wasteland: The Art of Wasteland Success (Pyramid Scheme Edition) (struck through).
