In a world transformed into a deadly game filled with dungeons and monsters, humanity looked to Lee Se-jun and his Messiah Guild as their only hope for salvation. To the public, Se-jun was a righteous hero dedicated to ending the chaos. But to his closest comrades, he was a deceitful tyrant who murdered them in the final dungeon to maintain his rule over the world. Among the betrayed was Kim Woo-jin, who, instead of meeting his end, wakes up in the past with all his memories intact. The game has reset, but this time, Woo-jin isn't playing to save the world—he is playing to hunt the hero.
Armed with the knowledge of future events, hidden dungeons, and legendary items, Woo-jin abandons the path of the righteous to walk the solitary road of the Necromancer. He raises armies of the undead and manipulates the political landscape of the guilds, using deception and overwhelming power to dismantle the Messiah Guild piece by piece. Kill the Hero is a high-octane regression fantasy that subverts traditional tropes, featuring a brilliant, cold-blooded protagonist who will stop at nothing to execute his revenge against the false idol Lee Se-jun.
