Synopsis
Demon Slayer: Kimetsu no Yaiba – The Movie: Infinity Castle (Japanese: 劇場版「鬼滅の刃」無限城編, Hepburn: Gekijō-ban Kimetsu no Yaiba: Mugen Jō-hen) is a 2025 Japanese animated dark fantasy action film based on the "Infinity Castle" arc of the 2016–20 manga series Demon Slayer: Kimetsu no Yaiba by Koyoharu Gotouge. It is a direct sequel to the fourth season of the anime television series as well as the manga fourth, fifth, and sixth adaptations, following the film Mugen Train (2020) and the feature-length compilations To the Swordsmith Village (2023) and To the Hashira Training (2024). It is directed by Haruo Sotozaki, produced by Ufotable, and written by the studio's staff members.
Unlike the Swordsmith Village and Hashira Training adaptations, which are compilations of episodes from the anime series, Infinity Castle is a feature-length multi-film adaptation due to the arc's content and dramatic pacing, similarly to Mugen Train. It is the first film of a trilogy announced in June 2024, immediately following the airing of the fourth season's finale.
Officially titled Demon Slayer: Kimetsu no Yaiba – The Movie: Infinity Castle – Part 1: Akaza Returns, it was released in Japan on July 18, 2025, by Aniplex and Toho. It was released by Crunchyroll through Sony Pictures Releasing in select Asian countries in August, before releasing in all other territories the following month. The film broke several box office records and grossed $478 million worldwide. It became the highest-grossing film of 2025 in Japan, the second highest-grossing Japanese film worldwide, and the second highest-grossing film in the country's history, behind Mugen Train. The film received generally positive reviews from critics, who praised its action sequences, visuals, and engaging story, although some noted pacing issues.
