Demonic Witches Harem: Having Descendants Make Me Overpowered! Novel

Matthew, a 25-year-old otaku transported to another world by fate, discovers he's the illegitimate son cursed by his own family. Hunted for his dark magic—a power feared and hunted across the realm—he trains in secret with his true father, Theo, alongside his mother, Dalia. When knights and clerics from the Promised Land shatter their escape, Matthew flees to the legendary Elysian Plains, humanity's last sanctuary for the gifted.

But the Saint strikes him down before he can reach safety. In his final moments, a mysterious figure grants him an astounding revelation: he is the descendant of the Lord of Calamity, chosen to claim a kingdom and vanquish all opposition. When Claude awakens, the power he receives isn't the system he imagined—it's something far darker and more potent.

[Welcome to the Elysium of Darkness System, Lord of Calamity.]

The voice resonates through his very being, each command pulsing with sinister intent. His purpose becomes clear through the first quest: expand Elysium's population by using his seed and blood to father children with demons and witches, establishing his legacy across realms where dark magic thrives.

Now wielding unprecedented power, Claude must navigate a harem of formidable supernatural women while building his dominion in a world that once condemned him. With the Lord of Calamity's bloodline awakened within him, his journey transforms from survival to conquest—writing history in blood and darkness across the Elysian Plains and beyond.
