Having Defeated the Demon Lord, the Hero's Next Task is Perpetuating His Descendants -Sorceress-
In order to secure the survival of humanity after going into decline due to the Demon Lord, the Kingdom came to the conclusion that the Hero's blood is necessary;
therefore, the Hero was ordered to perpetuate his descendants by having many women bear said descendants.
Among them were many skilled individuals like this one, so in order to bear strong descendants, the Hero needed to make babies with many more women.
