The Devil Within the Walls

Upcoming fanfiction He was just another fan of Attack on Titan—until death gave him a second life inside the very world he once admired. Reborn years before Wall Maria’s fall, he awakens with Lelouch’s Geass: the power of absolute command. But in a world ruled by fear, corruption, and monsters both human and Titan, one man’s power isn’t salvation—it’s temptation. To end the endless cycle of hatred, he’ll unite humanity under one banner… even if he must become the devil that leads them. As soldiers march, walls crumble, and hearts break, his voice will echo through history: “If peace demands my damnation—then so be it.” In a tale of strategy, sacrifice, and rebellion, the question remains: Will he save humanity… or control it?
