The story takes place in two worlds where humans and magicians are incompatible.Humans live in cities called “caves”, while magicians who worship demons live in “magic worlds”. Magicians call humans “trash” and humans call magicians “monsters”, and they hate each other. The magician uses his magic to create a “gate” that connects the two worlds, and uses the humans in the “cave” as an experiment to practice magic, and the cave residents who have suffered from it also revolt against the magician. The protagonist, Kaiman, is one of the magic victims of the “cave”. Cayman’s head turned into a lizard because of magic, and he lost all memory at the same time. However, Cayman’s body is thus immune to magical ineffectiveness. In order to pursue his memory and restore his original appearance, Cayman and his friend Nikaidou began to hunt magicians. And the killer of “The Magician’s World” also appeared in the “Cave”, and the fight was about to break out……
