Crunchyroll has confirmed that Demon Slayer: Kimetsu no Yaiba – The Movie: Infinity Castle will begin streaming on its platform at the end of the month, announced during Anime Expo. The news matters because the film was a major commercial success following its 2025 cinema release, becoming the highest-grossing anime film of all time and the seventh-highest-grossing film of 2025, and fans had been waiting for a home-viewing option after Crunchyroll had earlier said it would be available "only in theaters".

Infinity Castle is the first instalment to adapt Demon Slayer's final chapters, depicting Tanjiro Kamado and the Demon Slayer Corps battling Muzan and his demon army, including some of the Upper Ranked Demons, and features Channing Tatum's anime debut as Keizo. The film earned matching 98% critic and audience scores on Rotten Tomatoes. The streaming release will offer English and Japanese dubs, along with Spanish, Portuguese, French, German and Italian, among other languages.
