Matthew, a 25-year-old otaku, never imagined his obsession with fantasy worlds would turn into reality—until a fatal gas leak ended his life and transported him to another world. 

But this wasn’t the second chance he hoped for. Born as the illegitimate son of an affair, his very existence was a stain on his family’s honor, and his father relentlessly sought to kill him. 

Yet Matthew, now Claude, survived, again and again, driven by an unyielding will to live.

Until one day he discovered his power darkness. Feared and reviled in this world, dark mages were hunted and burned alive. 

Knowing his gift could become his downfall, he trained in secret under Theo, his true father. 

When he turned sixteen, he, his mother, Dalia, and Theo planned their escape from the small town. 

But their attempt was thwarted by knights and clerics from the Promised Land. 

Though he narrowly escaped with his life, the cost was high—his family’s safety shattered. 

Wounded and desperate, Matthew fled to the fabled Elysian Plains, the last hope for those like him.

However, just as they neared Elysium, Claude was struck down by the Saint—killed in an instant. Yet, against all odds, he lived again. The voice of the man before him confirmed it.

“You are the descendant of the Lord of Calamity. I grant you this kingdom and the power to crush all who stand in your way.”

The man’s lips curled into a chilling smile.

“Write your own bloody history, Claude. Until we meet again, I expect you to have conquered this world.”

And with that, Claude awakened to a power beyond his imagination—the legendary system he had longed for. Yet, as he soon realized, it was no system at all.

[Oh? So you expect me to be like the ones in your memories?]

[A system that grants you quests and guides your hand?]

[Very well.]

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

A series of commands etched themselves into his mind, each word dripping with ominous purpose.

[Your first quest has been issued.]

[Increase the number of dwellers in Elysium using your seed and blood. Spread your legacy by making demons and witches bear your children.]

Claude's head snapped toward the voice. A man stood before him, his dark purple ponytail swaying slightly, red eyes glowing in the dim light.

There was something eerily familiar about him, but now wasn't the time to dwell on it—his mother's condition was his priority.

"What do you mean?! What happened to my mother?"

Claude shot to his feet, his voice sharp with urgency as he stepped closer, now face-to-face with the man.

The man bowed his head slightly. "My Lord, it's me—Sun," he introduced himself.

Claude didn't react, even when Sun finally able to transform into humanoid form, his mother was the priority.

Sun hesitated, his ears drooping slightly. "That's… actually…" He exhaled, voice heavy with reluctance. "Your mother has Drunen Sickness."

Claude's breath hitched. "What? How?" His brows knitted as dread settled in his chest.
