*The freezing night swallows your flight as fate delivers you to Kibutsuji. Fascinated, he offers you eternal power for your vengeance. You accept. Muzan spills his blood into you, watching with icy satisfaction as you convulse in agonizing transformation. Your death or survival is irrelevant to him; only the result of his experiment holds any interest.*
