Joseph Knox, one of the most prolific and well-known serial killers on the planet.A person considered so demented and manic that even trying to reason with him was believed to be a waste of time. A man so far gone that he seemingly didn't deserve any pity even on his deathbed.So why? Why would a man like him receive a second chance? And why did the world around him seem so familiar?Disclaimer: AU when it comes to some parts of Madara's plan(I'll try to make it make sense at least), and aliens don't exist in this world

In humanity’s final war against the Demon Lord, the strongest heroes fell—not by the enemy’s hand, but by their own, twisted into madness by a cruel illusion. Betrayal. Bloodshed. Despair… and then, silence.Only one person remained: Riley—the weakest warrior of them all. Powerless. Ignored. Forgotten.But he saw through the Demon Lord’s deception. The tyrant was on the brink of death—so weak even a fly could’ve finished him off.And Riley did just that, drawing every last ounce of strength to bite off the demon’s head.Victory? Not quite. A final, desperate strike from the Demon Lord pierced him from behind, killing him instantly.But fate wasn’t done with him yet.Riley awoke ten years in the past—when the online game [Apocalypse] was launched. Before demons descended. Before monsters overran the world.And this time, he wasn’t starting from nothing. He had a decade of experience—and a second chance.Even more shocking, he didn’t awaken his old D-rank Strength Boost talent. This time, he received something far more terrifying: an SSS-Rank Gluttony talent!He could now devour anything—monsters, items, talents, even traits—and gain their power.Ding![You have devoured: Iron Fang Wolf][Acquired: +4 Strength, +2 Agility, Skill: Bite (F-rank)][You have devoured: Goblin ShamanAcquired: +8 Intelligence, Skill: Mana Bolt (E-rank), Talent: Minor Spellcasting Efficiency][You have devoured: Flaming Salamander Drake][Acquired: +22 Endurance, Trait: Dragon’s Resilience, Skill: Flame Breath (C-rank)]Now, there is no demon, no god, no monster who will stand in his way. He will devour everything—and save the world.But the power of Gluttony was a double edged sword. If he wasn’t careful… he could be the one getting consumed.
