"What did he share with you, the man inside?" In a post-apocalyptic future, two totally distinct groups coexist in a dark and sinister setting. In the realm of the "sorcerers", they have the power to create portals and indulge in the joys of transformation on test subjects, who reside in "Hole", a refuge for unfortunate mutilated individuals. Caiman, who hasn't always looked like a lizard, is a great fan of the gyozas prepared by his friend Nikaidô, and strives to find the one responsible for his current appearance. A major advantage in his favor is that he is immune to the magic of "wizards", which does not suit them at all.
