Chapter 180 of Kimetsu no Yaiba shifts the momentum back to the enemy. Freed from Tamayo's poison, a transformed Muzan slaughters arriving squads of Demon Slayers and kills Tamayo herself, declaring he will end every hunter before the night is over.
Pressing deeper into the Infinity Castle, Tanjiro and Giyu learn that Muichiro and Genya have died. Grieving yet resolute, Tanjiro forces himself onward, troubled that Senjuro's letter revealed the Hinokami Kagura holds thirteen forms while he knows only twelve. Kiriya realizes time has run out for the slayers to reach Muzan before he recovers, and warns the first arriving squad to wait for the Hashira rather than engage.
The squad ignores him and tries to cut down the cocoon. It splits open, and a transformed Muzan bursts free, killing the fighters in a swift, brutal flurry before they can react.
Word of the two fallen slayers reaches Tanjiro. Senjuro's letter turns out to mention a thirteenth Hinokami Kagura form. Shrugging off Tamayo's poison, Muzan breaks loose and adopts a new fighting form to slaughter many of the hunters. Tamayo dies.
Holding Tamayo's severed head, Muzan mocks her failed poison; when she begs for the return of her family, he coldly tells her to join the relatives he claims she killed before crushing and absorbing her. Far off, Yushiro collapses in agony, sensing her death. Muzan then locates a second squad, wipes it out, and proclaims that he alone will kill every Demon Slayer that night. This Infinity Castle Arc chapter was collected in Volume 21.

Demon Slayer: Infinity Castle earned $778 million globally and nearly 40 billion yen in Japan, but it still couldn't top Mugen Train's domestic record. Here's why that barely matters....

The transformation everyone knows, the follow-up question nobody would touch. Why we made a smooth R&B track about the golden glow Dragon Ball never talks about....
