Picture: Demon Slayer: Kimetsu no Yaiba Infinity Castle – Aniplex
It’s been over 14 months since Demon Slayer: Kimetsu no Yaiba Infinity Castle debuted in cinemas, and finally, it has been confirmed that the film is coming to Netflix on September 28, 2026.
The Demon Slayer anime ended after four incredible seasons in 2024, and while fans will not receive any further episodes, the story concludes with a trilogy that covers the final arc of the manga, Infinity Castle. Demon Slayer: Kimetsu no Yaiba Infinity Castle broke numerous records upon its release in cinemas around the world in July 2025, amassing over $800 million at the box office, making it not only the highest-grossing film in Japanese history, but also the highest-grossing anime film ever by almost $300 million.
Given that every season of the Demon Slayer anime is already available to stream, Netflix licensing the film felt inevitable. Although it took some time for the movie to be added, it remains a major addition to Netflix’s anime library.
Thrust into the heart of the Infinity Castle, the Demon Slayer Corps is surrounded by countless demons, including the remaining members of Muzan’s Upper Moon Six. It’s a race against time and attrition as Tanjiro and the Hashira desperately fight their way through the labyrinth to hunt Muzan and end the demons once and for all.
