“Demon Slayer to Begin Streaming Free on August 16” was accurate only as a 2025 event headline. Crunchyroll’s promotion began on August 16, 2025, when it hosted a free YouTube watch party for approximately 24 hours. The stream was later available as a replay for seven days, so it was never a permanent free release of the anime.
What the August 16 event actually was
Crunchyroll announced the Demon Slayer: Kimetsu no Yaiba watch party on August 13, 2025. The broadcast started at 10:00 a.m. PT on August 16, 2025, on Crunchyroll’s official YouTube channel.

It was a scheduled livestream rather than a new season launch or an unrestricted YouTube library. Viewers could watch together with real-time live chat, and Crunchyroll planned for the broadcast to run for roughly 24 hours. Afterward, the recording was scheduled to remain available for seven days.
That replay window ended in August 2025. Anyone looking for the event now should not expect the original watch-party video to function as an ongoing free way to watch the series.

What was included in the free watch party?
The advertised program covered a substantial portion of the released anime story, along with Demon Slayer: Kimetsu no Yaiba—The Movie: Mugen Train. Crunchyroll listed these story arcs:
| Included program | Format or note |
|---|---|
| Final Selection | Television series content |
| First Mission | Television series content |
| Asakusa | Television series content |
| Tsuzumi Mansion | Television series content |
| Natagumo Mountain | Television series content |
| Rehabilitation Training | Television series content |
| Entertainment District | Television series content |
| Swordsmith Village | Television series content |
| Hashira Training | Television series content |
| Mugen Train | Feature film |
The event was presented in Japanese with English subtitles. Crunchyroll’s announcement did not promise an English-dubbed version for the YouTube broadcast.
Was Infinity Castle part of the free stream?
No. The watch party did not include Demon Slayer: Kimetsu no Yaiba Infinity Castle. The event concluded with trailers for Infinity Castle, which was being promoted as the next theatrical chapter.
At the time, the first film was scheduled for theatrical release in the United States and Canada on September 12, 2025. That promotional connection likely caused some headlines and social posts to blur the difference between the older material in the watch party and the new film.

As of August 9, 2026, the August 16 free-streaming promotion is a past event. It should not be confused with the separate Crunchyroll streaming premiere for the first Infinity Castle film.
Crunchyroll listed Demon Slayer: Kimetsu no Yaiba Infinity Castle for streaming beginning July 28, 2026, at 8:00 a.m. PT. Availability can vary by region, and this release is separate from the temporary 2025 YouTube watch party.
What viewers should take away
- The correct year was 2025: the event began on August 16, 2025, not August 16, 2026.
- It was temporary: the livestream lasted approximately 24 hours, followed by a seven-day replay period.
- It was not a permanent free catalog: the event did not make all of Demon Slayer freely available on YouTube or Crunchyroll.
- It was subtitled: the announced YouTube presentation was Japanese audio with English subtitles.
- Infinity Castle was not streamed as part of it: the event showed trailers for the film, while the series episodes and Mugen Train made up the watch-party program.
For current viewing, the relevant option is to check Crunchyroll’s regional availability rather than search for an active August 16 free stream. The original promotion has ended, while the 2026 Infinity Castle streaming release is a different offering.

Where was the free Demon Slayer event shown?
Crunchyroll hosted it on its official YouTube channel. The livestream ran for approximately 24 hours and its replay was scheduled to remain available for seven days.

The Bottom Line
The headline needs a date correction: Crunchyroll’s free Demon Slayer YouTube watch party began on August 16, 2025, not 2026. It was a temporary, subtitled livestream featuring earlier series material and Mugen Train, with Infinity Castle represented only by trailers. The later Crunchyroll streaming release of Infinity Castle, listed from July 28, 2026, was a separate event.
