There are two major film releases in the Demon Slayer series: the standalone feature Demon Slayer: Kimetsu no Yaiba – The Movie: Mugen Train (2020) and the recently premiered film trilogy based on the “Infinity Castle” arc. Several other releases, like To the Swordsmith Village and To the Hashira Training, are compilation films that reformat TV episodes for the big screen.
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)[a] 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.[5]
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 $667 million worldwide, becoming the highest-grossing Japanese film, the highest-grossing international film in the U.S. previously held by Crouching Tiger, Hidden Dragon (2000), and the fifth-highest-grossing film of 2025.[b] The film received generally positive reviews from critics, who praised its action sequences, visuals, and engaging story, although the pacing received some criticism.

Kagaya’s son Kiriya and daughters Kuina and Kanata lead the operation by mapping the Infinity Castle with the Kasugai crows and locating its inhabitants, with former Hashiras Tengen Uzui and Shinjuro Rengoku standing guard.
Shinobu Kocho encounters Upper Rank Two Doma, recognizing he was responsible for her older sister Kanae‘s death. Despite her use of poisons, Doma develops immunity to her attacks, ultimately killing and consuming her. Shinobu’s adoptive younger sister Kanao Tsuyuri arrives too late to save her and takes her place in the battle against Doma, while the Kasugai crows announce Shinobu’s death to the rest of the Demon Slayers.
