Ethan Brooks had a life that many would envy—success, stability, and the freedom to live as he pleased. But beneath the surface lay a void. Years of sacrifice and relentless self-improvement had left him hollow, trapped in a monotonous cycle of work and fleeting escapism. Then, in the blink of an eye, that life was ripped away. Waking in an unfamiliar forest with blood on his hands and a ravenous hunger clawing at his core, Ethan stumbles upon an impossible truth: he has transmigrated into the body of Muzan Kibutsuji, the Demon King from *Demon Slayer*. As the memories of Muzan’s battles, fears, and sins flood his mind, Ethan is forced to confront the horrifying reality of his situation. But Ethan is not Muzan—not yet. With a sharp intellect and a relentless drive for control, he resolves to rise above the weaknesses of his predecessor. The former Muzan cowered in the face of Yoriichi Tsugikuni’s overwhelming power, but Ethan refuses to fall into the same traps. Armed with a strategic mind and a ruthless will, he begins his journey to rewrite Muzan’s legacy. Yet the path is fraught with peril. The Demon Slayer Corps hunts him with unrelenting resolve, and the memories of countless lives Muzan destroyed haunt his every step. The specter of Yoriichi looms large, and Ethan knows that to survive, he must evolve beyond Muzan’s limitations—shedding sunlight’s fatal curse, mastering new powers, and uniting the scattered demon forces. But power comes at a cost. Ethan is no hero, and the line between survival and monstrosity begins to blur. To live, he must kill. To thrive, he must dominate. And to win, he must embrace the very darkness that terrifies him. With each step, the remnants of Muzan’s will threaten to consume Ethan, molding him into a true Crimson Monarch. Will Ethan rise as a ruler who transcends his predecessor, or will he succumb to the same hubris that doomed Muzan before him? In a world where strength reigns supreme, Ethan must navigate treacherous alliances, crushing betrayals, and his own evolving morality to achieve his ultimate goal: absolute control over life and death itself. *Crimson Monarch: The Rise of Muzan Kibutsuji* is a gripping blend of reincarnation, strategy, and dark ambition. Witness the story of a man torn between his humanity and his monstrous destiny, as he redefines what it means to be the Demon King. For fans of high-stakes power struggles, moral dilemmas, and epic confrontations, this fanfic offers a fresh take on the *Demon Slayer* universe. Step into a world of blood, ambition, and the unyielding hunger for survival. Ethan Brooks’s journey is just beginning—and the world of *Demon Slayer* will never be the same.

(also I suck at writing so yeah English is not my first language.) i don't own the cover so if you are the artist and want me to take it down let me know.
