Demon King Ascension System

Aeris was born the weakest boy in Stonevale. No magic. No status. No future. Only one thing gave his life meaning, his little sister, Alba, the sickly girl he had spent years protecting. Then the Empire came for her. They called Alba a Sacred Vessel. The villagers called it an honor. Aeris knew it was a death sentence. He fought. He begged. He even turned against the people he once called family. But none of it was enough. So when Alba was placed on the altar, Aeris made one final choice. If the ritual demanded a sacrifice… it would take him instead. Something answered. Something that should have remained buried. When Aeris opened his eyes, the ritual chamber was destroyed, Alba was missing, and a strange voice appeared before him: [Congratulations, Host.] [The Demon Core has chosen you.] Now Aeris has power. More power than he ever dreamed of. But there is something the voice doesn’t tell him. Every time Aeris uses that power, something inside him changes. And the Empire isn’t hunting him because he ruined their ritual. They’re hunting him because of what woke up inside him. With Alba gone and seven Imperial Mages standing between him and the truth, Aeris begins a bloody hunt for the people who tried to sacrifice his sister. But the deeper he goes, the more terrifying the questions become. Why was Alba really chosen? What exactly is the Demon Core? And why does the mysterious System seem to know things about Alba that even Aeris doesn't? Because the truth waiting at the end of his journey may be far worse than death. Alba was never the sacrifice. She was the key. And Aeris? He may be the monster that was created to open the door.

When a cosmic event called The Reset merges the digital and physical worlds, chaos consumes Earth. Each human receives a “King System,” granting unique abilities and the chance to become a ruler in this brutal new hierarchy. Leon Vale, a 26-year-old mechanic and outcast, awakens to find his system inactive. Mocked and left for dead, Leon discovers his “broken” system hides a forbidden protocol: the ability to absorb and steal the powers of other Kings. Armed with this gift — and a vengeance born from betrayal — Leon sets out to hunt the new Kings. Along the way, he allies with Iris Kade, an ex-soldier with a loyalty-based combat system, and forms a ragtag empire of survivors. As Leon’s power grows, he learns of The Architect, the entity behind The Reset, and uncovers a secret war between divine factions using humanity as their testing ground. From the ashes of civilization, Leon must decide: will he become humanity’s savior, or its final tyrant? The answer will shape the new age — and crown The Last King.

Daniel wasn't your everyday nobody. His life transitioned from that of a loser to that of a winner after being bitten by some bastard. "You're my perfect successor." "My ass..."
