Demon Slayer Infinity Castle OTT release: Why April 9 has fans watching closely

It has been nearly nine months since Demon Slayer: Kimetsu no Yaiba – The Movie: Infinity Castle (Part 1 — Akaza’s Return) arrived in theatres, yet there is still no official confirmation about its OTT release. The film hasn’t appeared on rental platforms either, leaving fans in a long wait. Still, a small but meaningful update has sparked fresh excitement among viewers eager to stream the movie at home.

Reports suggest that April 9 has been marked as the final day of the film’s theatrical run in Japan. That detail matters more than it sounds. Once a film completes its cinema cycle, it usually clears the way for digital distribution. For fans of Demon Slayer: Kimetsu no Yaiba, this date feels like a turning point—an indication that an OTT announcement could follow soon after. The previous seasons of the show are available on multiple platforms including Crunchyroll, Jiohotstar, Prime Video, and Netflix. So, if the Infinity Castle gets green light for the OTT, expect it to land on these platforms as well.

Originally released in July 2025, the film was produced by Ufotable and quickly gained attention for its striking animation and intense action sequences. Directed by Haruo Sotozaki, the movie adapts the popular Infinity Castle arc from Koyoharu Gotouge’s manga series.


The story pushes the stakes higher, following Tanjiro Kamado, Nezuko Kamado, and the Hashira as they enter the shifting labyrinth of the Infinity Castle. Their mission: confront the Upper Rank demons and ultimately face Muzan Kibutsuji. The arc is known for its relentless pace and emotional weight, which the film captures with cinematic scale.

For those wanting to revisit earlier parts of the story, previous seasons of Demon Slayer are already available across platforms like Netflix, Crunchyroll, Prime Video, and JioHotstar.

For now, nothing is officially locked in. But April 9 sits there like a quiet signal—suggesting the wait might finally be nearing its end, even if fans still have to sit tight a little longer.
