The eighty-fourth chapter of Demon Slayer pits a rampaging, blood-hungry Nezuko against a burning Daki, forces Tanjiro to physically restrain his sister from attacking a wounded bystander, and ends with Tengen's sudden arrival and a single decisive blow.
Pinned to the ground, Daki uses her obi to break free, lopping several limbs off Nezuko. Before she can gather them, Nezuko's severed hand clamps onto the obi, the limbs still joined by her oddly hardened blood. Drops of that blood land on Daki and ignite her instantly, drawing a scream of agony. Nezuko's limbs reel back and reattach, each cut self-cauterizing, and she stamps down hard enough to set Daki's head ablaze.
After stomping repeatedly, Nezuko kicks Daki through one building and into the next. Following to keep up the assault, she comes upon a wounded woman tending a bleeding injury and staring at her in terror. Nezuko slips into a trance and rushes the woman, unable to hold back her thirst for blood.
Tanjiro leaps onto Nezuko and presses his blade across her like a muzzle to hold her back, shouting for her to resist the hunger. She claws his face trying to break loose. He apologizes for making her fight after she smelled her own spilled blood, assures her that her big brother is there to protect her, and tells her she can heal now. Nezuko regains her footing and bursts through the ceiling with him on her back, wrecking the room.
The walls are sliced apart as Daki barges in with her scorched face, seething as she forces her burned body to regenerate. Torn between guarding the nearby bystanders and blocking Daki without freeing Nezuko, Tanjiro chooses to defend the public, but Tengen abruptly appears, marveling at Nezuko's flashy demonization. He ribs Tanjiro for once boasting at the Ubuyashiki estate about Nezuko's self-control. Daki excitedly greets the Hashira and is coldly told to be silent, dismissed as far too feeble for an Upper Rank title. The chapter closes with her severed head dropping into her lap, leaving her stunned.

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 internet found an infinite money glitch. So did Yamcha. A smooth R&B track about the easiest money in the Dragon Ball world and the one man who keeps paying for it....
