Demon Slayer: Kimetsu no Yaiba Infinity Castle (2025)

Demon Slayer: Kimetsu no Yaiba – The Movie: Infinity Castle is a 2025 Japanese animated dark fantasy action film based on the "Infinity Castle" arc of the 2016–20 manga series Demon Slayer: Kimetsu no Yaiba by Koyoharu Gotouge. It is a direct sequel to the fourth season of the anime television series as well as the manga fourth, fifth, and sixth adaptations, following the film Mugen Train (2020) and the feature-length compilations To the Swordsmith Village (2023) and To the Hashira Training (2024). It is directed by Haruo Sotozaki, produced by Ufotable, and written by the studio's staff members. It follows the Demon Slayer Corps in their decisive climactic battle against Muzan Kibutsuji and the remaining Upper Ranks within the titular "Infinity Castle".

Unlike the Swordsmith Village and Hashira Training adaptations, which are compilations of episodes from the anime series, Infinity Castle is a feature-length multi-film adaptation due to the arc's content and dramatic pacing, similarly to Mugen Train. It is the first film of a trilogy announced in June 2024, immediately following the airing of the fourth season's finale.

It was released in Japan on July 18, 2025, by Aniplex and Toho. It was released by Crunchyroll through Sony Pictures Releasing in select Asian countries in August, before releasing in all other territories the following month. The film became the seventh-highest-grossing film of 2025, grossing $793 million worldwide, and the highest-grossing international film in the U.S. (previously held by 2000's Crouching Tiger, Hidden Dragon). The film also broke multiple box-office records, including becoming the highest-grossing Japanese film, the highest-grossing R-rated animated film, the second-highest-grossing adult animated film and the first R-rated non-American and animated film to gross over $700 million mark, as well as overtaking The Simpsons Movie (2007) as the highest-grossing film based on an animated television series and the second highest-grossing traditionally animated film, behind The Lion King (1994). It's also the highest-grossing traditionally animated film in its initial release, surpassing the initial gross of The Lion King. The film received generally positive reviews from critics, who praised its action sequences, visuals, and engaging story, although the pacing received some criticism. The film won Best Animation Film at the 49th Japan Academy Film Prize, a record-breaking seven awards including Film of the Year at the 10th Crunchyroll Anime Awards, and was nominated for Best Motion Picture – Animated at the 83rd Golden Globe Awards.

Plot

After recovering from Kagaya Ubuyashiki's trap and subduing Tamayo, Muzan Kibutsuji retreats into his dimensional stronghold, the Infinity Castle, and traps the Demon Slayer Corps inside. The Demon Slayers are separated and face hordes of Lower Rank-level demons as they search for Muzan and Tamayo. Kagaya's son, Kiriya, and daughters, Kuina and Kanata, lead the operation by mapping the Infinity Castle with the Kasugai crows and locating its inhabitants, with former Hashiras Tengen Uzui and Shinjuro Rengoku standing guard.

Shinobu Kocho encounters Upper Rank Two Doma, recognizing him as her sister Kanae's killer. Despite her use of poisons, Doma develops immunity to her attacks, ultimately killing and consuming her. Shinobu's adoptive younger sister Kanao Tsuyuri arrives too late to save her and takes her place in the battle against Doma, while the Kasugai crows announce Shinobu's death to the rest of the Demon Slayers.

Zenitsu Agatsuma faces his former senior Kaigaku, who became the new Upper Rank Six after an encounter with Upper Rank One Kokushibo. Angered by Kaigaku's lack of guilt over his betrayal, which led to their master Jigoro committing seppuku, they battle. Kaigaku voices his frustration at being compared to Zenitsu, but is killed when he uses a self-taught Thunder Breathing form. Zenitsu passes out and momentarily enters the afterlife, where Jigoro reaffirms he has always been proud of him; he is then rescued by a disguised Yushiro, who has been using his Blood Demon Art to help the Ubuyashikis map the Infinity Castle. Meanwhile, Nezuko Kamado takes a drug produced by Shinobu and Tamayo to restore her humanity and is placed under the care of Sakonji Urokodaki.

Tanjiro Kamado and Giyu Tomioka fight Upper Rank Three Akaza. Though Giyu unlocks his mark to enhance his power, Akaza continues to overwhelm them. Determining that the demon is able to target people based on their willpower, Tanjiro recalls memories of Inosuke's ability to detect attacks and observing his late father in combat. He enters the Transparent World and Selfless State, giving him heightened perception and masking his emotions, successfully beheading Akaza. However, Akaza's body continues to resist and fight Tanjiro and Giyu while headless, pushing them to the brink.

Their persistence causes Akaza to remember his tragic past; he was a young criminal named Hakuji, who stole to fund his father's medication. After being caught stealing numerous times, his father committed suicide to unburden him, leading to a chance encounter with a dojo owner, Keizo. Hakuji served as his sole disciple while caring for his sick daughter, Koyuki. Hakuji and Koyuki eventually became engaged, but she and her father were poisoned by a resentful neighboring dojo that wanted his land while he visited his father's grave. The vengeful Hakuji massacred all of the dojo's members and was turned into a demon during an encounter with Muzan afterwards.

Despite regenerating his head out of sheer will, Akaza realizes his mistakes through his restored memories. Giving a final smile of gratitude to Tanjiro, he fatally injures himself and stops his regeneration, accepting defeat. He reconciles with his loved ones and reunites with Koyuki, who embraces him before accompanying him to Hell. Tanjiro and Giyu pass out from exhaustion as their victory is announced by the Kasugai crows.

Kokushibo and Doma are disappointed by Akaza's death, while the Infinity Castle's owner, Upper Rank Four Nakime, manipulates its layout to confuse the Ubuyashikis. Muzan traps Tamayo in a cocoon of his flesh, remaining confident of his victory over the Demon Slayers.
