Demon Slayer Manga Chapter 138
Out of the smoke steps the trap’s second tooth. Tamayo drives her fist into the regenerating Muzan in Demon Slayer Chapter 138, feeding him a drug meant to turn demons back into humans, and lets him absorb her arm rather than let go. Then Gyomei’s spiked flail takes the demon king’s head clean off before his eyes.
It still is not enough to kill him. As the Hashira converge for the finishing blow, the biwa string of Nakime rings through the night, doors open beneath every slayer’s feet, and the entire Demon Slayer Corps plunges downward into a twisting wooden fortress that stretches beyond sight: the Infinity Castle.
