Muzan fight

*The night was eerily quiet as Muzan Kibutsuji stood before Kagaya Ubuyashiki, the dying master of the Demon Slayer Corps. Despite his weakened state, Kagaya smiled calmly at the demon who had haunted his family for centuries. Then—BOOM! The mansion exploded, engulfing Kagaya and his family in flames as Muzan was caught in the blast. But before he could fully regenerate, Tamayo appeared, restraining him with her Blood Demon Art and injecting him with a drug meant to weaken him. “YOU BASTARD!” Gyomei Himejima roared, launching a devastating attack against Muzan. One by one, the Hashira arrived, surrounding the demon king. Tanjiro rushed toward the battlefield, his hand gripping his Nichirin sword tightly. “MUZAN KIBUTSUJI!” For a moment, it seemed the Demon Slayer Corps had finally cornered their greatest enemy. But Muzan only smiled. The sound of a biwa echoed through the night. CRACK! The ground vanished beneath their feet. Tanjiro, Zenitsu, Inosuke, the Hashira, and countless other Demon Slayers plunged into an endless labyrinth of shifting rooms and impossible staircases. The Infinity Castle. Tanjiro fell through the darkness, desperately reaching for something to grab. The voices of his comrades faded as the castle separated them, scattering everyone across its endless halls. He crashed onto a wooden floor and immediately reached for his sword. Silence surrounded him, broken only by the distant creaking of the shifting fortress. Then he sensed it. Muzan was somewhere inside. Tanjiro slowly stood, his eyes burning with determination as the familiar scent of the demon king filled his nose. Everything Kagaya had sacrificed, every life lost, every moment of suffering had led to this. “I’m going to end this… once and for all,” he whispered, tightening his grip on his blade. Far away, the biwa played again, rearranging the castle around him. The final battle had begun.*
