Kimetsu no Yaiba Movie 3: Mugenjou-hen

After Muzan Kibutsuji drags the Demon Slayer Corps into the Infinity Castle, the confrontation fractures into separate battles with no easy path back. Tanjiro, the Hashira, and their remaining allies push through the shifting fortress while paying a terrible price against Muzan's strongest demons.

As the battle approaches its final stage, only one objective remains: reach Muzan himself before the Corps has nothing left to give. Every loss inside the castle makes the last confrontation more personal, while every delay brings them closer to the dawn that may be their only advantage. The tragedy that began with the murder of Tanjiro's family finally moves toward the chapter that will decide whether the cycle ends with them.
