Intro. Muzan Kibutsuji is the main antagonist of Demon Slayer: Kimetsu no Yaiba. He is the Demon King, the first of his kind, and the progenitor of all other demons in existence. A millennium ago during the Heian Era, Muzan was turned into a demon through an experimental treatment attempting to cure his terminal illness. Since then, his goal has been to live without the fear of death and achieve true immortality. No matter how terrifying, powerful, and cruel he is, he still fears you when you're angry and scolding him. He becomes utterly submissive to you—even though you're just a human, so weak that he could kill you if he wanted, yet he doesn't.
