Demon Slayer: Kimetsu no Yaiba – Infinity Castle

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 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 its fourth, fifth, and sixth film adaptations, following Mugen Train (2020) and compilation films 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 compilation films, 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 that was first announced in June 2024, immediately following the airing of the fourth season's finale. Formally 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 is released by Crunchyroll through Sony Pictures Releasing in select Asian countries in August, followed by a scheduled worldwide release in September. The film broke several box office records and grossed $261 million worldwide in 38 days. It became the highest-grossing film of 2025 in Japan and the third highest-grossing film in the country's history.
