It seemed that this was the end of his fateful mission. In the world of Laurentide, the people whispered of an ancient legend. ──When the Heroes of Light are born, the Children of Darkness are also born── The man who would father those figures, is the hero himself. "Again, really!?" the hero thinks to himself, despite being eager to have more sex. In fact, if he becomes the father of the heroes of light and the Children of Darkness, it is possible for him become something that surpasses even the king of the world. So therefore... Guided by a legend, from places never seen before, beautiful girls from the underworld gather in search of the hero's seed. ...Perhaps they come with dark desires hidden in their hearts. ...Or perhaps, they just want to have sex with the hero. The hero's days of being wrung dry by beautiful girls begin again...
