The fourth season of That Time I Got Reincarnated as a Slime continues its long run, but fans waiting for Episode 17 will have to wait a little longer than expected. The popular anime series, which follows Rimuru Tempest and his growing nation of Tempest, has seen a schedule change for its upcoming episode. The delay comes from a programming conflict on Japanese television, not from any production issues with the anime itself.
Episode 17, which is also known as Episode 89 in the overall series count, was first set to release on July 31, 2026. But the broadcast plans have changed. Japanese network NTV will air the movie Jurassic World Dominion in the time slot normally reserved for the anime. Because of this, the new episode will now arrive on August 7, 2026. Some international sources list the date as August 8, 2026, depending on the time zone and streaming platform.
Episode 17 Release Date and Schedule Change
The official X (formerly Twitter) account for the That Time I Got Reincarnated as a Slime anime confirmed the schedule adjustment. The announcement explained that the episode will not air on its original Friday slot. Instead, viewers in Japan will see the new episode on August 7, 2026 on NTV. For international audiences, the episode will be available on Crunchyroll at the same time, with the simulcast following the Japanese broadcast.
This delay only affects Episode 17. The rest of the season’s schedule is expected to continue as planned after this one-week shift. The production team at Studio 8-Bit has not reported any problems with making the episode. The quality of the animation and the action scenes that fans enjoy should remain at the same level as previous episodes.
Here is the updated release schedule for the upcoming episodes:
- Episode 17 – August 7, 2026
- Episode 18 – August 14, 2026
- Episode 19 – August 21, 2026
- Episode 20 – August 28, 2026
- Episode 21 – September 4, 2026
- Episode 22 – September 11, 2026
- Episode 23 – September 18, 2026
- Episode 24 – September 25, 2026
Season 4 of That Time I Got Reincarnated as a Slime is planned to run for five cours, which means it will have more than 60 episodes in total. The first two cours are airing back-to-back without any breaks, giving fans a steady flow of new content from spring through fall 2026. The first 24 episodes follow a weekly release pattern, with new episodes coming out every Friday. The show airs in Japan on NTV’s “Friday Anime Night” block at 11:00 PM JST.
What to Expect in Episode 17
The upcoming episode is titled “Rubelios, the Land of Convergence” (集束の地ルベリオス). This title hints at a major location in the story that will play a key role in the ongoing conflict.
Season 4 of That Time I Got Reincarnated as a Slime shows Rimuru Tempest moving closer to his dream of creating a world where humans and monsters can live together in peace. The nation of Tempest continues to grow and prosper. But not everyone supports this vision. Granville Rozzo and his granddaughter Maribel Rozzo stand against Rimuru. They believe that humans need to be controlled and ruled over to be protected. This puts them on a direct path of conflict with Rimuru and his allies.
At the same time, other powerful demon lords are making their own moves. Demon Lord Leon is working on his own secret plans in the Golden City of El Dorado. The story is building toward a larger clash between different factions. Heroes who protect humanity and demon lords who want to rule the world are all moving toward a single point of conflict.
Episode 17 will likely continue to develop these storylines. The political tensions between nations, new alliances, and threats from various powerful forces are all coming together. The episode will also show more of the conflict between Rimuru and the Rozzo family, as well as the other forces that are getting involved in the struggle for control of the world.
Where to Watch the Episode
International fans can watch That Time I Got Reincarnated as a Slime Season 4 on Crunchyroll. The streaming service offers the series with subtitles in multiple languages. The English dub version may follow at a later date, but the subtitled version will be available on the same day as the Japanese broadcast.
The show is also available on other platforms in some regions. Viewers can find the series on Crunchyroll Amazon Channel in certain countries. Some regions may also have access through Netflix and other local streaming services. However, Crunchyroll remains the main platform for the simulcast release outside Japan.
The exact release time on Crunchyroll varies by time zone. For viewers in the United States, new episodes typically arrive in the early morning hours. The show follows the Japanese broadcast schedule, so international fans can watch the episode shortly after it airs in Japan.

What Makes This Season Different
Season 4 of That Time I Got Reincarnated as a Slime is the longest season of the series so far. The decision to run for five cours shows the confidence that the production team and the network have in the show’s popularity.

The season started on April 3, 2026. Since then, the show has been releasing new episodes every week, with only one delay earlier in the season. Episode 5 was delayed due to Golden Week scheduling. The current delay for Episode 17 is the second schedule change of the season.

The action scenes, character designs, and world-building animation have all been praised by fans and critics alike.
The voice cast also returns for Season 4. Miho Okasaki voices Rimuru Tempest, with Megumi Toyoguchi as the voice of the Great Sage and Makoto Furukawa as the voice of Veldora. The returning cast helps maintain the familiar feel of the series that fans have come to love over the years.
The story in Season 4 is also more complex than previous seasons. The political elements are stronger, and the conflicts involve more factions and characters. The season is setting up major events that will change the world of the series in significant ways. The current arc involves the conflict with the Rozzo family, but other threats are also building in the background.
Fans who have been following the series since the beginning will find plenty to enjoy in this season.
