That Time I Got Reincarnated as a Slime the Movie: Tears of the Azure Sea has reached digital platforms, but there is no single worldwide launch date to circle. The official Japanese announcement started limited rentals and digital purchases on August 12, then corrected one important detail: Hulu's rental listing will not begin until September 3.
That makes this release useful for fans and easy to misunderstand. The movie is available digitally in some markets, Crunchyroll currently lists it, and other services are following their own schedules. A viewer who sees an August 12 headline should not assume the same date applies everywhere.
Here is what the current release information actually tells us, plus where the film fits with the anime's busy fourth season.
The digital release started in Japan first
The official announcement lists August 12 as the start of a limited rental window and a digital purchase option. The rental period runs through October 31 in the Japanese schedule, costs 1,100 yen in HD or SD, and gives viewers 72 hours to watch after renting. Digital purchase is listed at 2,546 yen in HD or SD, with the usual warning that each service can set its own timing and terms.
The rental list includes U-NEXT, iTunes Store, FOD, DMM TV, Prime Video, YouTube, and several Japan-focused anime services. U-NEXT had already carried the film since June 26, so it is not starting from the same point as every other platform. That difference is why a general "streaming now" label does not tell the whole story.
The official page also separates rental from digital purchase. Renting gives a short viewing window; buying is intended to remain available without that 72-hour limit. That is basic digital-store language, but it matters when fans are comparing prices or deciding whether to watch once before the rental window closes.
Hulu is the release-date catch
The August 18 correction is the detail most likely to save viewers from a wasted search. The original notice treated Hulu like the other rental services, but the updated schedule moves Hulu's rental start to September 3 at midnight in Japan. The rest of the August 12 information remains the launch point for the listed services.
That does not mean Hulu has lost the movie or that the film is being removed from every other platform. It means one service has a later start. Digital anime releases often arrive in waves because the rights and storefront schedules are handled market by market, and this title is a clear example of that process.
For viewers outside Japan, the safest approach is to search the full English title on the service used in their country. The Japanese prices and dates are useful context, not a promise that an app in another region will show the same button on the same day.
What Tears of the Azure Sea is about
The movie is a new story written under Fuse's original concept and supervision. It begins after Rimuru Tempest and his allies finish the founding festival for the Demon Kingdom Federation Tempest. Their reward is supposed to be a break at a resort island ruled by Elmesia, the Celestial Emperor of the Sorcerous Dynasty of Thalion.
The vacation changes when Yura arrives from Kaien, an underwater kingdom that worships a sleeping water dragon. She has learned that someone inside her country wants to wake the dragon and attack the surface, so she carries an inherited flute to seek help. Rimuru and his companions agree to follow her home, where a larger scheme is already moving below the water.
That setup gives the movie a self-contained adventure while keeping the series' usual mix of politics, friendship, comedy, and sudden large-scale danger. Rimuru is not starting another trip from zero; he is taking the people around him on a holiday that turns into a national crisis.
The film arrives while Season 4 is still active
Tears of the Azure Sea is landing in the middle of an unusually busy period for the franchise. The TV anime's fourth season is airing now, and the official site has been running weekly reaction campaigns around new episodes. An official ABEMA marathon also scheduled the earlier seasons, OAD episodes, and related material across August 21–24, giving new viewers a convenient catch-up window in Japan.
The film does not replace Season 4. It is a separate feature-length story built around Rimuru's trip to Kaien, while the TV series continues its own larger arc. Viewers can treat the movie as a side adventure that expands the world rather than as an episode they need to fit between two weekly chapters.
For a simple watch plan, start with the TV anime if you are new to the franchise, then use the movie as a bonus story once you know Rimuru, Tempest, Elmesia, and the other major players. The film introduces Yura and Kaien, but its political relationships make more sense with the wider series context.
Where viewers outside Japan can look
Crunchyroll announced the international theatrical rollout earlier this year, including a May 1 release in the United States and Canada with English subtitles and an English dub. The service's current watch listing now includes Tears of the Azure Sea, but the exact playback options still depend on the viewer's region. Prime Video also has a listing with the English title, a 1-hour-44-minute runtime, and several audio and subtitle options.
Those listings are more useful than a single global date because they show how the film is actually reaching viewers: through a mix of theaters, digital stores, and subscription catalogues. A platform can list the movie while a rental or dub option remains unavailable in one country, so check the local page before assuming every format is ready.
The Japanese home-video release is scheduled for September 25. Its early-purchase package includes a serial code for the mobile game That Time I Got Reincarnated as a Slime: ISEKAI Chronicles, giving collectors another reason to wait even after the digital version arrives.
This is a release update, not a new movie announcement
Tears of the Azure Sea is already the second theatrical Slime movie, following Scarlet Bond. The new information is about access: Japan's rental and purchase rollout has begun, Hulu is delayed until September 3, and international services are adding the film on their own schedules. There is no new sequel title hidden in the update.
That distinction is useful because the franchise is already producing several kinds of news at once. Season 4 is airing, the official account is collecting episode reactions, and the movie is moving from theaters to home viewing. Keeping those threads separate makes it easier to tell what Rimuru fans can watch today and what they still need to wait for.
If you have already seen the movie in theaters, the digital release is a convenient second look. If you missed it, the best option depends on your country and whether you want a rental, a purchase, or a subscription listing. The sea is open; the dates are still local.
