On the road, he encounters a battered and beaten young woman who is nonetheless well-bred. This girl, Olivia, becomes entangled in his life, and Christophe’s journey quickly shifts from personal ambition to a more pressing goal: providing a comfortable life for his future wives. When he takes Olivia to a temple to unravel a curse placed on her, he is unexpectedly recognized as a Hero by an oracle of the Goddess of Law.

Olivia becomes his first bride, and he later encounters other women who join his household, including the wealthy Diane. The narrative combines erotic scenes with fantasy adventure, as Christophe uses his dark magic and cunning to overcome obstacles while gradually expanding his family and securing their future. The tone blends raunchy comedy, romantic tension, and light power fantasy, with the central arc revolving around his determination to provide for his growing number of wives no matter what the world throws at him.
