*In a sentence:* A castle full of inventive ways to fight and people who insist on explaining why

> Haruo Sotozaki delivers inventive animated combat and gives the demons enough history to make their suffering matter. We recommend it to series followers, with a warning that repeated flashbacks make an already long film feel longer.

## Synopsis

Inside the shifting Infinity Castle, demon slayers and their opponents fight a series of personal duels. Tanjiro Kamado (Natsuki Hanae), Giyu Tomioka (Takahiro Sakurai) and Zenitsu Agatsuma (Hiro Shimono) are among the combatants. Shinobu Kocho (Saori Hayami) faces Doma (Mamoru Miyano), while Akira Ishida voices Akaza. Grudges shape the encounters, and flashbacks explore the histories of the people involved. This animated action fantasy continues the *Demon Slayer* story as the first film in a concluding trilogy, with battles unfolding through a fortress whose layout keeps changing.

## Review

Haruo Sotozaki’s *Demon Slayer: Kimetsu no Yaiba Infinity Castle* is good action animation with an awkward habit of stopping to explain the people doing the fighting. We recommend it to those already invested in the series, provided they have some patience for repeated journeys into the past. As the first film in a concluding trilogy, it has plenty to get through and little interest in easing us into its mythology. At 156 minutes, the bursts of combat have to sustain a long evening.

The castle earns a substantial share of that running time. Yuichi Terao’s cinematography follows the fights through a shifting labyrinth, so that keeping track of the space becomes part of the excitement. We were exhilarated by the way the fights carried on through those changes, with the building itself making each encounter less predictable. The setting also gives the duels variety, although the sheer amount of movement sometimes makes it difficult to decide where to look.

Sotozaki understands that an elaborate arena still needs combat worth following. The personal duels have enough invention to reward attention to individual moves, and resentment gives the violence a purpose beyond demonstrating what the animation can do. That matters in an action fantasy this long, where a succession of interchangeable opponents would quickly become a chore. There is low-key comedy among the melodrama, too, and those lighter moments are welcome when so much else demands an intense response.

The demons benefit most from the attention paid to personal history. Akira Ishida voices Akaza and Mamoru Miyano voices Doma, and the performances give the antagonists enough presence to withstand the film’s busy imagery. The flashbacks ask us to reconsider people we have been watching as opponents, and some of that material is affecting. The trouble is that asking for sympathy becomes a familiar stage in the encounters, and familiarity starts to weaken the effect.

Manabu Kamino’s editing has the difficult task of holding these encounters together as one film. The repeated pattern of confrontation, recollection and combat gives it an episodic rhythm, and once that rhythm is established, another flashback can feel like a delay before the part we came for. Some histories deserve the time, especially when they deepen a demon’s character. Sotozaki lets too many of them interrupt the forward movement, making a film full of speed feel longer than it needs to.

Yuki Kajiura and Go Shiina’s music helps maintain the urgency, though it cannot solve that stop-start structure. The film also expects a fair amount of familiarity with the series, and its opening offers limited help with the mythology. Newcomers can follow the physical contests while still struggling to understand the weight attached to every grievance. The fights provide an immediate attraction, but they cannot supply all the missing context.

An action fantasy can get a long way on inventive combat, and Sotozaki supplies enough to make the interruptions worth tolerating. The sympathy for its enemies gives this one more to offer than a sequence of increasingly difficult fights. It still needs an audience willing to bring some knowledge and a fair amount of patience. Give it a large screen and an uninterrupted evening, but make your introduction to the series elsewhere.

*Fi1m score 74, published 15 September 2026.*

## What the critics say

Most critics respond warmly to Infinity Castle, with praise concentrated on Ufotable’s animation and the inventive combat within its shifting, labyrinthine fortress. The fights impress through their movement and staging, while the antagonists’ histories give the action emotional weight. Several reviews find that personal resentments and flashbacks deepen an otherwise familiar struggle between good and evil. The strongest enthusiasm comes from critics who see the film as a substantial reward for the series’ fans.

Reservations centre on repetition, structure and how much prior knowledge the film requires. Even favourable reviews find the stopping point unsatisfying, while Collider argues that the episodic construction weakens its cohesion as a film. The spread is largely between enthusiasm and qualified approval, rather than outright rejection. Accessibility produces a sharper disagreement: Screen Daily finds the complex mythology manageable for newcomers, whereas Deadline finds the lack of exposition makes the story difficult to follow without familiarity with the series.

## Straight answers

**Is Demon Slayer: Kimetsu no Yaiba Infinity Castle worth watching?**

*Demon Slayer: Kimetsu no Yaiba Infinity Castle* is worth watching for followers of the series, and we scored it 74. Haruo Sotozaki's duels through the shifting castle are inventive and the demons are given enough history to matter. Newcomers will struggle with the mythology, and repeated flashbacks make 156 minutes feel longer than they should.

**How long is Demon Slayer: Kimetsu no Yaiba Infinity Castle, and what is it rated?**

*Demon Slayer: Kimetsu no Yaiba Infinity Castle* runs 2h 36m and is rated 16 by the ICAA in Spain. It is an animation and action film.

**Where can I watch Demon Slayer: Kimetsu no Yaiba Infinity Castle in Spain?**

*Demon Slayer: Kimetsu no Yaiba Infinity Castle* is streaming on Amazon Prime Video in Spain. Availability is checked daily; the links above go straight to each service.

**How violent or frightening is Demon Slayer: Kimetsu no Yaiba Infinity Castle, and is it suitable for children?**

*Demon Slayer: Kimetsu no Yaiba Infinity Castle* carries a UK 15 certificate, so it is not for children. It is an animated action fantasy built around a series of violent personal duels between slayers and demons, with grudges and painful pasts shaping the fighting. Older teenagers used to the series will manage; the squeamish should expect sustained bloodshed.

**How does Demon Slayer: Kimetsu no Yaiba Infinity Castle compare to Princess Mononoke?**

*Demon Slayer: Kimetsu no Yaiba Infinity Castle* and [*Princess Mononoke*](https://film.one/film/princess-mononoke) both give their enemies enough sympathy to make the violence hurt, but Miyazaki's film is the more complete and the better of the two. It stands alone and leaves room to question the fighting, where Sotozaki's is one part of a trilogy that assumes you already know the series.

**What should I watch after Demon Slayer: Kimetsu no Yaiba Infinity Castle?**

After *Demon Slayer: Kimetsu no Yaiba Infinity Castle*, try [*Princess Mononoke*](https://film.one/film/princess-mononoke) (1997, Fi1m 88): More divided loyalties and wounded enemies, with room to question the fighting. Then [*The Raid*](https://film.one/film/the-raid) (2011, Fi1m 83): Another hostile building, with cleaner storytelling and little time for personal history; and [*A Chinese Ghost Story*](https://film.one/film/a-chinese-ghost-story) (1987, Fi1m 82): Supernatural danger, romance and comedy share space without crowding out the action.
