Description

Overview

Demon Slayer: Kimetsu no Yaiba - The Movie: Infinity Castle (Part 1 subtitled "Akaza Returns") is the first installment of a film trilogy adapting the final arc of Koyoharu Gotouge's manga. It opened in Japan on 18 July 2025. It was produced by ufotable and directed by Haruo Sotozaki, with Aniplex and Toho handling distribution in Japan.

Story

The Demon Slayer Corps faces its decisive battle against Muzan Kibutsuji, the progenitor of demons, and the surviving Upper Rank demons, in the otherworldly "Infinity Castle" that serves as the demons' stronghold. As the Japanese subtitle indicates, the first film centers on the fight against the Upper Rank Three demon, Akaza.

Style

The film is known for ufotable's blend of hand-drawn animation and digital compositing, following the earlier feature film Mugen Train. The visual treatment of the fire- and water-themed Breathing techniques has been one of the franchise's major draws.

Swords in the Series

The Demon Slayer Corps wield "Nichirin swords," forged from ore and sand that has absorbed sunlight and the only weapon in the story able to sever a demon's neck. The blade changes color depending on its wielder, and the series features swordsmiths who forge the weapons in a hidden village, evoking Japan's sword-forging traditions. The Nichirin sword is a fictional creation and is not based on any specific historical sword.

Cultural Impact

In 255 days of release, the film recorded about 27.34 million admissions and 40 billion yen domestically, becoming the second Japanese film after Mugen Train to pass that mark. Its final domestic gross reached about 40.2 billion yen over 266 days, with a worldwide total of roughly 117.9 billion yen. By bringing swords and swordsmiths to a vast international audience, the film has also helped spur broader interest in Japanese sword culture.
