First Demon Slayer: Infinity Castle Film Releases in UK Cinemas this September

An anime juggernaut is about to enter its final chapter! Crunchyroll have today announced the release date for Demon Slayer: Kimetsu no Yaiba Infinity Castle, the first in a feature film trilogy set to adapt the final story arc of Koyoharu Gotoge’s record-breaking dark fantasy manga. The film will be releasing exclusively in cinemas in the UK, Ireland and other territories from Friday 12th September 2025.

Crunchyroll describes the story of the film as follows:

Tanjiro Kamado – a boy who joined an organization dedicated to hunting down demons called the Demon Slayer Corps after his younger sister Nezuko was turned into a demon.

While growing stronger and deepening his friendships and bonds with fellow corps members, Tanjiro has battled many demons with his comrades – Zenitsu Agatsuma and Inosuke Hashibira. Along the way, his journey has led him to fight alongside the Demon Slayer Corps’ highest-ranking swordsmen, the Hashira, including Flame Hashira Kyojuro Rengoku aboard the Mugen Train, Sound Hashira Tengen Uzui within the Entertainment District, as well as Mist Hashira Muichiro Tokito and Love Hashira Mitsuri Kanroji at the Swordsmith Village.

As the Demon Slayer Corps members and Hashira engaged in a group strength training program, the Hashira Training, in preparation for the forthcoming battle against the demons, Muzan Kibutsuji appears at the Ubuyashiki Mansion. With the head of the Demon Corps in danger, Tanjiro and the Hashira rush to the headquarters but are plunged into a deep descent to a mysterious space by the hands of Muzan Kibutsuji.

The destination of where Tanjiro and Demon Slayer Corps have fallen is the demons’ stronghold – the Infinity Castle. And so, the battleground is set as the final battle between the Demon Slayer Corps and the demons ignites.

Since the anime premiered in 2019, Demon Slayer: Kimetsu no Yaiba has become one of the most popular anime franchises worldwide. The franchise’s first feature film, 2020’s Demon Slayer: Kimetsu no Yaiba Mugen Train holds the unprecedented record of the only anime film to ever be the highest grossing movie of the year. Subsequent theatrical releases To the Swordsmith Village and To the Hashira Training have served more as extended previews of upcoming television seasons, with Infinity Castle marking a full return to feature content.

Demon Slayer: Kimetsu no Yaiba Infinity Castle is directed by Haruo Sotozaki at ufotable, and releases in Japan on 18th July 2025.
