Demon Slayer: Infinity Castle OTT release date: Where to watch the biggest anime film of the year online after its historic box office run?

Demon Slayer: Infinity Castle OTT release date: After creating history at the global box office, Demon Slayer: Kimetsu no Yaiba The Movie Infinity Castle is finally heading to OTT. The first film in the trilogy that adapts the manga's final arc is set to begin streaming this week, giving millions of fans another chance to witness Tanjiro Kamado's biggest battle yet.


The movie was praised for its breathtaking animation, emotional storytelling, and high-stakes action during its theatrical run, and its digital release has been just as eagerly awaited. If you are wondering when the film will be available, where you can stream it, and whether it is releasing in India, here is everything you need to know.

The wait is almost over for anime fans. Demon Slayer Infinity Castle will begin streaming on July 28, 2026, nearly a year after its theatrical debut in Japan. The movie first premiered on July 18, 2025, before expanding to North America and several other international markets later that year. After completing its successful global cinema run, the film is now making its OTT debut.

The streaming release follows the usual pattern for major anime films. Studios often keep blockbuster releases exclusively in theatres for several months before making them available digitally. This allows the film to complete its worldwide theatrical journey before reaching a much larger audience through streaming.


Crunchyroll is the main streaming home for Demon Slayer Infinity Castle across most international markets. The film will be available from 8:00 am PT on July 28, which is 8:30 pm IST for viewers in India.

The platform will stream both the original Japanese version with subtitles and dubbed versions that were released during the theatrical run. Available languages may differ depending on the country.

In selected Asia Pacific markets, Netflix is also adding the movie to its catalogue on the same day. However, the Netflix release is limited to specific countries because of regional licensing agreements.

Created by Koyoharu Gotouge, Demon Slayer ended its manga run in 2020 after becoming one of the best-selling manga series in history. Studio ufotable then turned the franchise into a global anime phenomenon with its stunning animation, emotional storytelling, and blockbuster theatrical releases.

Instead of adapting the final Infinity Castle arc as another television season, ufotable announced that it would be released as a trilogy of films. The decision allowed the studio to give the manga's biggest battles a much larger cinematic scale while maintaining the visual quality the series is known for.


The gamble paid off spectacularly. Released in Japan on July 18, 2025, Infinity Castle opened to record-breaking numbers, earning over ¥7.3 billion (around US$49 million) in its first four days alone. It became the fastest film in Japanese box office history to cross ¥10 billion, doing so in just eight days, and eventually grossed more than ¥35 billion (over US$235 million) in Japan. The film also crossed US$320 million worldwide, making it one of the highest-grossing anime films ever and one of the biggest Japanese movie releases of all time.

The story picks up after the events of the Hashira Training Arc. As Muzan Kibutsuji launches his final attack, Tanjiro, the Hashira and the rest of the Demon Slayer Corps are pulled into the mysterious Infinity Castle, a massive fortress controlled by the demon Nakime.

Inside the castle, the rules of space and gravity constantly change, turning every battle into a deadly challenge. Tanjiro and his allies must face the powerful Upper Rank demons while moving closer to their final confrontation with Muzan.

The first movie focuses on several major fights while also giving more depth to key characters, including Giyu Tomioka, Sanemi Shinazugawa and other Hashira. Alongside the breathtaking action, the film delivers emotional moments that set the stage for the final chapters of the story.


Running for around 155 minutes, Infinity Castle delivers some of the most visually ambitious animation ufotable has ever produced. From the constantly changing architecture of the castle to the beautifully choreographed sword fights, nearly every sequence feels designed for the big screen.

The soundtrack further elevates the experience, with powerful music accompanying the emotional and action heavy moments. Fans and critics alike have praised the film for remaining faithful to the manga while expanding several scenes through cinematic storytelling.

While the first movie marks the beginning of Demon Slayer's final battle, the story is far from over. The remaining two films will complete the Infinity Castle storyline and bring Tanjiro's journey to its conclusion. Part two is currently expected to release in 2027, while the final chapter is likely to arrive around 2029, although official release dates have not yet been announced.
