The final battle of Infinity Castle is Muzan’s shifting fortress where Demon Slayers face the Upper Rank demons in deadly one-on-one battles, leading to the final showdown against Muzan himself.
Infinity Castle plunges Tanjiro, Nezuko, the Hashira, and the Demon Slayer Corps into Muzan’s otherworldly fortress—a shifting labyrinth of peril. Inside, they face the Upper Rank demons in intense, one-on-one battles that set the stage for the saga’s ultimate confrontation.
