What happens when a Powerful CEO in the Fashion World who already promised to marry his girlfriend, is forced to marry a woman from a lowly family, compared to his high-esteemed family background, against his wish?

Birth rates are decreasing. Hope is vanishing. The world has gone gray.Humanity, drifting in quiet collapse, receives an email.Every person on Earth. Simultaneously.The Aegis Mandate.Disguised as a cosmic aptitude test, it triggers The Incident of Separation—a global psychic cataclysm that erases identities, wipes memories, and divides all survivors into three factions: Law, Neutral, and Chaos. Overnight, cities become battlegrounds. Apartments become dungeons. Ordinary people become monsters—or the ones who hunt them.Ragnar Vhagar was just a loner university student. Now, thanks to a system he didn’t ask for, he’s a newly minted Demon King, locked in a crumbling apartment with goblins under his sofa and a glowing soul crystal next to his frozen peas. His new job? Build a deadly domain, defend it from invading “Heroes,” and somehow level up fast enough to not die.Alongside him is Isabelle Thorne, a razor-sharp warrior of few words and one very sharp sword. Their reluctant alliance, born in blood and snark, evolves into trust—and maybe something dangerously close to affection—as they rise together through the layers of the game-like world they’re trapped in.With each conquered domain and defeated boss, Ragnar realizes the truth: the dungeons aren’t meant to crown a winner. They’re meant to break the players. The Law faction wants control. The Chaos faction craves destruction. But Ragnar? He wants something they’re all too afraid to say out loud:Freedom.In the ruins of Kanta’s ogre stronghold, Ragnar and his misfit warband take their biggest step yet—claiming a kingdom, unifying a fractured system, and preparing for what comes next. The Heroes are watching. The gods are stirring. The world is watching a war.And somewhere deep beneath it all... Ragnar is rewriting the rules.

Strength.... That's all that matters in the end.

After being abandoned by his own family, and shunned for having no mana in a world dominated by magic, ex-prince Arvell Relas Vispia was forced to live on the streets with whatever meagre money he had left.

However, fate had something else in store for Arvell.

After meeting the spirit inhabiting his amulet, Arvell gets reborn as a Nephilim.

A being that has the powers of a god.

Time, Space, Life, Death.

All submitted to the authority of a Nephilim.

Betrayed by those he once called family, Arvell swore to get revenge.

Revenge on all those that mocked him and shunned him as a 'failure.'

Revenge on those who betrayed him without a second thought.

This is a tale of how a young prince shunned by the world as a 'failure' rises and ascends to the pinnacle of strength.
