‘That Time I Got Reincarnated as a Slime’ Season 4 Episode 20 Release Date and Time

Rimuru Tempest is not slowing down, and neither is the fandom keeping track of every single episode drop this summer. As ‘That Time I Got Reincarnated as a Slime’ Season 4 barrels toward its next installment, fans are once again circling their calendars to make sure they do not miss a single second of Tempest’s ongoing political drama.

The isekai favorite has built one of the most dedicated weekly followings in anime right now, and with the back half of Season 4 finally settling into a rhythm, viewers want a clear picture of when Episode 20 actually lands. Here is everything currently known about the release, the schedule, and what the story has been building toward.

‘That Time I Got Reincarnated as a Slime’ Episode 20 Release Date

Episode 20 of ‘That Time I Got Reincarnated as a Slime’ Season 4 is set to premiere on August 28, 2026, following the pattern already confirmed for the two episodes before it. With Episode 19 already dated for August 21 and Episode 20 following on August 28, the season’s Friday rhythm appears set to hold for the immediate future, barring any further adjustments from the Japanese broadcast side.

That stability is a welcome shift after a stretch of turbulence earlier in the run. The show had previously confirmed a sudden delay, with an episode bumped from its originally scheduled July 31st release to a newly planned launch in August due to broadcast changes in Japan. A recap episode filled the gap at the time, which pushed the numbering and airdates slightly out of sync with what fans had expected earlier in the season.

Season 4 Episode Schedule and Where to Watch

New episodes of ‘That Time I Got Reincarnated as a Slime’ Season 4 continue to follow a consistent weekly cadence once they are locked in. New episodes release on Fridays at 7 a.m. PT and 10 a.m. ET on Crunchyroll, giving international fans a dependable window to check for new content once the Japanese broadcast has aired.

Crunchyroll is streaming the season across North America, Central America, South America, Europe, Africa, Oceania, the Middle East, CIS and Southeast Asia, with episodes releasing in both English subtitles and an English dub. In Japan, the anime continues to air on NTV’s Friday Anime Night programming block.

International viewers should keep in mind that the overseas rollout does not happen simultaneously with the domestic broadcast. For fans outside Japan, the wait for new content stretches slightly longer than for domestic audiences, since the anime’s official broadcast comes first before the international platform release follows on its set schedule.

Fans tracking exact timing down to the hour have another resource to lean on as well. Episode 19 is listed with a raw broadcast on Friday, August 21, at 2 p.m. UTC, followed by the subtitled release an hour later at 3 p.m. UTC, a pattern that should carry over into the release window for Episode 20 the following week.

What to Expect From the Ongoing Rozzo and El Dorado Storylines

Season 4 has leaned heavily into the political tension simmering across Tempest, and Episode 20 arrives at a point where several threads are converging at once. This season of the anime covers Chapters 100 through 115 of the source manga, giving longtime readers a rough sense of just how much material still needs to be adapted before the current cour closes out.

The story follows Rimuru’s dream of an alliance between humans and monsters coming closer to fruition, with Granville Rozzo and Maribel Rozzo clashing with Rimuru over their own plan to protect mankind by ruling over it, while in El Dorado, Leon works toward goals of his own. That standoff has only intensified as the season has progressed.

Recent episodes have already shifted the balance of power within the Rozzo family. Now that Mariabell has been defeated, Granbell Rozzo is preparing for a massive war against Rimuru, and Yuuki Kagurazaka has involved himself as well, searching for the weapon that Demon Lord Luminus has reportedly been hiding. That escalation sets up plenty of ground for Episode 20 to cover once it arrives.

Beyond the immediate Rozzo conflict, there is a larger arc still waiting in the wings. The awakening of a new Hero draws near according to the season’s official overview, meaning Episode 20 could be laying groundwork for a reveal that fans have been anticipating for weeks.

Studio 8bit and the Franchise’s Bigger Picture

‘That Time I Got Reincarnated as a Slime’ has built its reputation over three previous seasons on detailed world building and political storytelling rather than pure spectacle, and Season 4 has largely continued that same approach. The series follows Mikami Satoru, a man reincarnated in another world as a slime named Rimuru, who works to build a nation where humans and monsters can coexist.

Production has remained steady behind the scenes even with the scheduling hiccups earlier in the run. Studio Eight Bit remains behind the production, continuing its work from the previous three seasons, and that continuity has helped keep the show’s visual identity consistent as it heads deeper into its most ambitious season yet.

The franchise has also been expanding well beyond the weekly anime broadcast. The franchise’s expansion continued alongside the anime itself, with a second film, ‘Tears of the Azure Sea,’ having released on February 27, 2026, shortly before Season 4 began. That film has given fans another entry point into Rimuru’s world even as the television series works through its current cour.

Looking further ahead, Season 4 is shaping up to be a massive undertaking overall. The season is planned to be the biggest in the franchise’s history, with five full cours of episodes stretched out over the next couple of years, meaning Episode 20 is really just one step in a much longer journey still to come.

With the Rozzo family’s war preparations accelerating and a new Hero’s arrival still looming on the horizon, which storyline are you most hoping ‘That Time I Got Reincarnated as a Slime’ Season 4 Episode 20 finally pushes forward when it premieres on August 28.
