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 eyes cracked open, only to immediately squint as the piercing light stung his vision.

Blinking several times, he forced himself to adjust before slowly rising to his feet.

A vast expanse of white stretched endlessly around him.

No sky. No ground. Just an empty void, like an isolation room in a mental hospital—cold, sterile, and suffocating.

"Oh… right. I'm dead," he muttered, the memory surfacing with a dull ache.

His gaze swept the void, lips curling into a wry smirk. "What is this place? A waiting room before judgment? Am I finally about to meet that so-called Goddess of the bastard church and be condemned for my sins?"

He rubbed his chin, feigning thoughtfulness. "I did kill plenty of Her people."

Despite his sarcastic tone, a heavy sigh escaped him. Strangely, he felt calm. Yet beneath that thin veil of indifference, something twisted inside him—a bitter, unspoken regret.
