Demon Slayer Infinity Castle Arc release date and latest news

The show's fourth season premiered in summer 2024, covering the Hashira Training Arc from the manga – a storyline that could be seen as the calm before the storm. It precedes the epic finale of Infinity Castle, a long story arc where the heroes confront their demonic nemesis Muzan Kibutsuji.

But when can we expect the Infinity Castle trilogy to arrive? Read on to learn everything we know so far.

Demon Slayer Infinity Castle release date

Demon Slayer: Kimetsu no Yaiba Infinity Castle will be released in UK cinemas from 12th September.

That's two months later than the Japanese release date, which is on 18th July.

News that Demon Slayer would bow out with three movies was first announced in January 2025.

At the time, Crunchyroll president Rahul Purini said: "Demon Slayer has been a phenomenal franchise, and we at Crunchyroll are delighted to have been a part of it from the beginning.

"Crunchyroll is thrilled to be able to bring this trilogy of films to fans, on the big screen, and it promises to be one of the truly epic and consequential pop cultural events of our time when it hits cinemas."

What is the Demon Slayer Infinity Castle plot?

Crunchyroll has released a synopsis for the film, which reads: "Tanjiro Kamado – a boy who joined an organisation 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 programme, 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."
