The set combining volumes 3 and 4 at a special price! In the third story, there's excitement in the Zombillenium horror themed park run by actual monsters. Brought in by Behemoth himself, the vampire Bohemond Jaggar de Rochambeau IIII is brought in to consult, his mission: to increase return on investment for the shareholders, but for Behemoth that return has to be in souls. In the 4th chapter, the park has never been better: its popularity has peaked following demonic reforms by Behemoth, who then decides to play his property in a very special competition-a witches' Sabbath!
