Demonic Witches Harem: Having Descendants Make Me Overpowered! Novel

Claude never expected his otaku fantasies to become real—until a gas leak killed him and he awoke in another world. Reborn as the illegitimate son of an affair, he became a target for his own father's murderous rage. Despite repeated attempts on his life, he survived through sheer determination. When Claude discovered his power over darkness, a reviled and hunted magic in this world, he trained secretly under Theo, his true father. At sixteen, he and his family attempted to escape their town, but were intercepted by knights and clerics. Though Claude survived, his family's safety was destroyed. Fleeing to the Elysian Plains, he was struck down by the Saint—killed instantly. Yet he lived again, awakening before a mysterious figure who revealed Claude's lineage as descendant of the Lord of Calamity. Granted a dark kingdom and immense power, Claude received his first command: populate Elysium by fathering children with demons and witches, spreading his bloodline to build his legacy.
