The first instalment of the Demon Slayer Infinity Castle movie trilogy was released on September 12 in the US and UK, and from the get-go had record-breaking box office takings projected.
The film did indeed break box-office records; however, it still isn't on multiple streaming services just yet. Currently, you can buy the film on Amazon Prime Video, but as of the time of writing, Crunchyroll hasn't shared a streaming release date on its end.
Hopefully, it will appear on the streamer before Demon Slayer Infinity Castle 2 drops, but we'll keep you posted as more news heads our way.
Demon Slayer: Infinity Castle movie story and recap
The first Demon Slayer: Infinity Castle movie adapted part of the Final Battle portion of the manga, which consists of the Infinity Castle arc (chapters 137-183) and the Sunrise Countdown arc (chapters 184-205). Specifically, the first movie adapted chapters 137-157.
The Demon Slayer: Infinity Castle movie picked up where Demon Slayer season 4 and Hashira Training left off, with Ubuyashiki predicting an approach from Muzan and detonating his entire complex (he and his family along with it) in the hopes of stopping the demon leader.
While Muzan just about escaped, the main Hashira all converged. Despite being beheaded, Muzan wasn't defeated and was able to trap each Hashira inside the demon's HQ of Infinity Castle (hence the name). From there, they must battle to escape, kill the Upper Ranks and, ultimately, defeat Muzan and put an end to the demon scourge once and for all.
As the name suggests, that saw the Infinity Castle – Muzan’s HQ – come into play, with the eternal battle between demons and demon slayers being brought to a definitive end here. In the movie's three fights, Upper Rank 3 Akaza returned from Mugen Train to do battle with Tanjiro and Giyu; Insect Hashira Shinobu faced Doma, the who killed her sister, and Zenitsu confronts Kaigaku.
Of those fights, Tanjiro and Giyu defeated Akaza, but not before we were given a glimpse into Akaza's tragic backstory before being turned into a demon by Muzan.
Zenitsu invented a new Thunder Breathing technique to put Kaigaku to the end once and for all. Sadly, Shinobu fared less well against Upper Rank 2 Doma, succumbing to his vicious attacks. The sequel setup, though, suggests Kanao will be stepping up to fight him, while Inosuke is also on the hunt for a strong demon to confront. Muzan, though, remains in the wind as time runs out to find him...
This is the list of arcs so far and how Infinity Castle fits into the bigger picture:
- Demon Slayer season 1 (Unwavering Resolve arc – Chapters 1-53)
- Demon Slayer season 2 (Mugen Train and Entertainment District arcs – Chapters 54-97)
- Demon Slayer season 3 (Swordsmith Village arc – Chapters 98-127)
- Demon Slayer season 4 (Hashira Training arc – Chapters 128-136)
- Demon Slayer: Infinity Castle movie trilogy (Infinity Castle and Sunrise Countdown arcs – Chapters 137-204)
Demon Slayer Infinity Castle review and Rotten Tomatoes score
Despite some structural issues, we loved Demon Slayer Infinity Castle. Our four-star Demon Slayer Infinity Castle review lauded Ufotable's best-in-class animation and expressed surprise at just how effectively it tugged at the heartstrings.
Our reviewer wrote, "Demon Slayer: Infinity Castle storms past Mugen Train to become the series' gold standard – all thanks to another animation masterclass by Ufotable and a gripping, peril-filled story simmering with personal resentment and touching backstories."
That's a feeling largely echoed by other reviewers. As of writing, Infinity Castle's Rotten Tomatoes score stands at 98%, meaning it's one of the best-reviewed anime movies of all time.
Is Demon Slayer season 5 happening? And is Infinity Castle the finale?
To avoid any confusion: no, Demon Slayer: Infinity Castle is not Demon Slayer season 5. We're getting three movies to wrap up the series in cinemas instead.
Demon Slayer: Infinity Castle is definitely the final arc, however, with Tanjiro, Inosuke, and Zanitsu’s stories drawing to a close once the anime ends. But it's not going to be on television; it's a theatrical exclusive and, for all intents and purposes, replaces what would have been Demon Slayer season 5 in terms of chronology.
That’s not to say the saga can continue elsewhere but, right now, Ufotable is only adapting the story of Koyoharu Gotouge’s official manga, which ended in May 2020.
Demon Slayer: Infinity Castle movie trailer and poster
The first main trailer for Demon Slayer Infinity Castle focuses on endings.
'The Final Battle Begins' reads the text accompanying the trailer, with renewed focus on Tanjiro's upcoming showdown with Akaza, who was the demon behind Rengoku's killing in 2020's Mugen Train.
The teaser also featured the reveal of two themes in Infinity Castle, performed by prolific artists LiSA and Aimer, respectively.
