Demon Slayer: Infinity Castle is a theatrical movie trilogy event, so where you can watch it depends on timing: first in cinemas, then later on streaming (most likely Crunchyroll), and finally on other digital platforms.

Demon Slayer Infinity Castle Where To Watch (Quick Scoop)

Is Demon Slayer: Infinity Castle out yet?

  • The Infinity Castle story is being released as a movie event, not a weekly TV season.
  • The film (often referred to as “Demon Slayer: Kimetsu no Yaiba – Infinity Castle”) has a theatrical release around September 12, 2025, in the US and other regions.
  • Around late 2025, many fans were still watching it in cinemas or hunting for late screenings, especially in bigger cities.

So depending on when you’re reading this, it might still be:

  • Only in theaters
  • In a “transition” phase (leaving cinemas, not yet fully on streaming)
  • Or just arriving on major anime platforms

Official ways to watch (no spoilers)

1. Movie theaters

  • Infinity Castle launched as a big-screen movie event, promoted directly as “only in movie theatres” at first.
  • Fans on forums mention they had to travel to other cities to catch remaining screenings once the main run started slowing down.

If your region still has active showtimes:

  • Check local cinema chains (search your city + “Demon Slayer Infinity Castle showtimes”).
  • Look for special anime or “event” screenings, since some theaters bring it back for limited runs.

2. Streaming platforms (most likely destination)

There are strong clues pointing to Crunchyroll as the primary legal streaming home when the movie leaves theaters:

  • Crunchyroll is listed as one of the production companies for Demon Slayer: Infinity Castle.
  • Official trailers are hosted on Crunchyroll’s channels with direct links to Crunchyroll’s site and trial offers, suggesting it will stream there after the theatrical window.

What this usually means (based on typical anime movie patterns):

  • Step 1: Theatrical-exclusive period (no streaming).
  • Step 2: After some months, it appears as a premium or regular title on Crunchyroll in most regions.
  • Step 3: In some countries, it may have different partners (e.g., local streamers), but Crunchyroll is still the main global anchor.

Because exact dates and availability can vary by country, the safest move is:

  • Search directly on Crunchyroll for “Demon Slayer: Kimetsu no Yaiba – Infinity Castle”.
  • If it doesn’t show up yet, it’s probably still in or just exiting its theater window.

3. Other digital / OTT options

Some outlets report on OTT and digital-release timing:

  • Entertainment and tech sites have covered expected OTT release windows and platform speculation (usually naming Crunchyroll as the main destination, possibly followed by regional platforms).
  • Third-party streaming or “free movie” sites (like random streaming pages or uploads on video sites) may host the film but are often unauthorized or legally dubious.

For a safe and legal watch:

  • Prefer official platforms (Crunchyroll, your local licensed anime streamer, or future digital purchase/rental services like major storefronts).
  • Be cautious of sites that promise “free HD Infinity Castle” with lots of pop-ups or unclear licensing.

What fans are saying on forums

“You’ll need to wait a little longer for it to appear on Crunchyroll since it’s still showing in select theaters.”

“I watched it in theaters today, but I had to travel quite a distance to get there.”

Key vibes from community discussions:

  • Many people in late 2025 were between cinema and streaming: theaters still had screenings, but everyone was already asking “when will it hit Crunchyroll?”.
  • Moderators and experienced users repeatedly remind others that sharing links to pirated streams is not allowed, and that the legal route is cinema now, streaming later.

Quick FAQ

Is Infinity Castle a series or movie?

  • It’s presented as a movie event (the start of the final battle) rather than a normal season, with a runtime around 2 hours 35 minutes for the movie entry listed.

Will it 100% be on Crunchyroll?

  • Crunchyroll is a producer and is heavily featured in official trailers and marketing, which makes it the overwhelmingly likely streaming home once the movie leaves theaters.
  • Exact regional rights and dates can differ, so always double-check in your local app or on their site.
