Demon Slayer: Infinity Castle Review — Anime’s Biggest Movie Ever

Demon Slayer: Kimetsu no Yaiba – The Movie: Infinity Castle released in Japan on July 18, 2025, and rolled out to Crunchyroll theaters internationally over the following months. Directed by Haruo Sotozaki and animated by Ufotable, it’s the first chapter of a planned trilogy adapting the manga’s climactic “Infinity Castle” arc — and it didn’t just perform well, it rewrote the box office record books for anime entirely.

A Direct Sequel, Not a Recap

Unlike To the Swordsmith Village (2023) and To the Hashira Training (2024), which were largely compilations of episodes from the TV anime, Infinity Castle is a true feature-length movie continuing directly from the fourth season’s finale. It picks up with the Demon Slayer Corps storming Muzan Kibutsuji’s shifting, labyrinthine stronghold — the titular Infinity Castle — to take on the remaining Upper Rank demons in a series of brutal, simultaneous battles.

The Battles: Zenitsu vs. Kaigaku, Tanjiro and Giyu vs. Akaza

The film splits its runtime across several Hashira and demon showdowns happening at once throughout the Castle. Zenitsu Agatsuma finally confronts Kaigaku, the former Thunder Breathing student who betrayed their shared master Jigoro — a fight loaded with years of buildup that ends with Kaigaku’s death and a gut-punch flashback to Jigoro’s final words. Elsewhere, Tanjiro Kamado and Giyu Tomioka team up against Upper Rank Three Akaza, with Giyu unlocking his Demon Slayer Mark to push the fight to its limit. Meanwhile, Shinobu Kocho’s fate against Doma is confirmed via the Kasugai crows, and Nezuko Kamado takes Shinobu and Tamayo’s drug in an attempt to reclaim her humanity.

A Box Office Phenomenon

The numbers here are staggering. Infinity Castle grossed $793 million worldwide, making it the seventh-highest-grossing film of 2025 — period, not just among anime. It became the highest-grossing Japanese film of all time, the highest-grossing R-rated animated film ever, and the highest-grossing international film in U.S. history, surpassing Crouching Tiger, Hidden Dragon. It also overtook The Simpsons Movie as the highest-grossing adult animated film in the U.S. For a movie that’s essentially one extended, R-rated fight sequence through a haunted house, that’s an extraordinary result — and a clear sign of just how massive the Demon Slayer fanbase has become globally.

What This Means for the Trilogy

Infinity Castle was announced in June 2024 as the first of a three-film series adapting the manga’s final arc, immediately following the airing of Season 4’s finale. Given the record-breaking performance of this first installment, Ufotable and Aniplex have every incentive to move quickly on the next two films — and with the Castle battles only getting more intense from here (Tanjiro and Giyu’s fight with Akaza alone is far from over by the credits), the next chapter has an enormous amount of momentum to build on.

Final Verdict

Demon Slayer: Kimetsu no Yaiba – The Movie: Infinity Castle is Ufotable at its absolute peak — relentless, gorgeously animated fight choreography wrapped around some of the manga’s most emotionally loaded confrontations. It earns every bit of its record-breaking box office run, and if you’ve been following Tanjiro’s journey since Season 1, this is essential viewing before the trilogy’s next chapter arrives. Just don’t expect a breather — this is two-plus hours of nonstop Castle warfare.
