The hentai is made in a fantasy style, telling us about a certain Devil's Stone, which by its power has taken over almost half of the world and turned it into a living hell. But one unlucky day, this evil and destructive stone was defeated by powerful wizards who decided to imprison the stone in the frail body of a young girl wizard named Isuka, from where it could only get out if the girl's body was abused. All the infernal creatures begin to pursue this young and beautiful girl. Once they catch her, they rape her in every way for one purpose only: to set the stone free.
