From the Start, the True Demon Mistook Me for an Impostor

[Not mindless power fantasy, not mindless power fantasy, not mindless power fantasy. Important things are said three times] [Fantasy + wild imagination + comedy + transmigration + mistaken identity + everyone projecting their own ideas onto him + the heroine comes knocking] After transmigrating to another world, Gersonk awakens the power of the “Stronger Against the Strong” law. But fearing the price it might demand, he resolves to keep his head down at all costs. Unfortunately, everyone else is blind, and insists on imagining him as the mysterious, powerful “Thousand-Faced Demon”! An adventurer who once clashed with him: “That has to be the Thousand-Faced Demon. If I hadn’t backed down fast enough, I’d be dead!” The lord of Falling Moon City: “In this city of warriors, it’s the Thousand-Faced Demon who understands martial virtue best.” A deranged cultist: “The abyss preserve us! The Thousand-Faced Demon is already a demigod-level powerhouse?!” Meanwhile, the heroine of this story, the real Thousand-Faced Demon, Rebessa, is utterly bewildered: “What does someone this strong want by disguising himself as me?” Even more bewildered is Gersonk: “I have no idea either!” And so begins a farce that throws the entire world into turmoil, all because everyone keeps making wild assumptions.
