Demon Slayer: Kimetsu no Yaiba Infinity Castle

A closer look at the story

The members of the Demon Slayer Corps and the Hashira are taking part in a joint strengthening programme called Hashira Training to prepare for the great war to come. The attack they have been expecting, however, arrives at the most unexpected moment: Muzan Kibutsuji, master of the demons, suddenly appears at the Ubuyashiki Mansion. The life of the Corps' leader is in danger. Tanjiro and the Hashira race to headquarters, but Muzan pulls them down into the depths of a mysterious void. The place they fall into is the Infinity Castle, the demons' stronghold. There, Tanjiro, Nezuko and the Hashira enter a life-or-death struggle with the Upper Ranks, the most powerful demons of all. And so the fuse is lit on the final war between the Demon Slayers and the demons. Directed by Haruo Sotozaki, this 156-minute 2025 anime feature has Natsuki Hanae, Takahiro Sakurai and Akira Ishida among its voice cast.
