‘That Time I Got Reincarnated as a Slime’ Season 4 Episode 19 Release Date and Air Time

Rimuru and the nation of Tempest are preparing for another exciting chapter, and fans of ‘That Time I Got Reincarnated as a Slime’ can now mark their calendars for a confirmed release date. Episode 19 of Season 4 is set to premiere on August 21, 2026, providing viewers with a clear target after weeks of scheduling changes disrupted the usual flow.

This isekai favorite has focused on developing its political storylines this season, rather than relying solely on action, keeping long-time fans engaged despite the recent scheduling turbulence.

According to episode guide reports, Episode 19 is scheduled to air on August 21, 2026, with Episode 20 following a week later on August 28. The season’s Friday release pattern appears to be stable for now, although further adjustments from the Japanese broadcast side remain a possibility due to the summer run’s previous disruptions.

The August 21 date comes after a scheduling hiccup earlier in the season. Episode 17 was initially set to debut on July 31 but was pushed back to August 7 due to programming changes in Japan. This delay shifted the subsequent episodes, including Episode 19, into their current slots.

Episode 18 was released on August 14, 2026, exactly one week after the delayed Episode 17. With this pattern holding, Episode 19’s air date of August 21 aligns with the show’s return to its regular weekly schedule.

‘That Time I Got Reincarnated as a Slime’ Season 4 premiered on April 3, 2026, and is designed to be the longest run in the franchise’s history, spanning five total cours. The first two cours are airing back to back, allowing fans to enjoy an unusually long stretch of new episodes compared to previous seasons that featured shorter breaks.

For international viewers, new episodes of ‘That Time I Got Reincarnated as a Slime’ Season 4 are set to release on Fridays at 7 a.m. PT, which corresponds to 10 a.m. ET. This timing has remained consistent throughout the season’s rollout on Crunchyroll, even with the recent one-week delay caused by the Japanese broadcast.

Crunchyroll continues to be the primary platform for streaming this season across a wide range of regions, including North America, Central America, South America, Europe, Africa, Oceania, the Middle East, the CIS region, and Southeast Asia. In Japan, the anime airs on NTV as part of its Friday Anime Night programming block, a time slot known for showcasing high-profile anime releases.

Prime Video has also been providing episode synopses for the season, giving viewers another way to follow the story beyond Crunchyroll’s simulcast. Episodes are confirmed to release with English subtitles and an English dub, offering fans options based on their viewing preferences.

The series is currently airing as part of the Summer 2026 anime schedule, and episode tracking calendars indicate that new entries typically populate with the most frequent updates occurring from Friday through Sunday, aligning with the Japanese broadcast schedule.

In Season 4, Demon Lord Rimuru’s ambition to forge an alliance between humans and monsters is advancing as Tempest thrives. Granville Rozzo and his granddaughter Maribel Rozzo have been at odds with Rimuru, pursuing their own plan to protect humanity that involves ruling over people instead of coexisting with monsters, according to the season’s official overview.

Meanwhile, in the territory of El Dorado, Demon Lord Leon is pursuing his own objectives, a subplot that has run parallel to the main Tempest storyline throughout the season. The season’s official synopsis has hinted at the impending awakening of a new Hero, a plot point that has yet to be fully explored in the most recent episodes.

Episode 16, titled Gran, the Hero of Dawn, aired on July 24, providing fans with a glimpse of the rising stakes as the season progresses. With Episode 24 currently scheduled for September 18, 2026, the season appears to be building towards a late summer conclusion for this batch of episodes before any potential break.

The ‘Slime’ franchise continues to expand beyond the weekly anime releases. A second film, ‘Tears of the Azure Sea,’ premiered on February 27, 2026, just weeks before Season 4 began airing, offering fans an additional look into Rimuru’s world right before the new season kicked off.

Studio Eight Bit remains at the helm of production, maintaining the visual identity of the franchise as the story delves into some of its most politically intricate territory yet. The studio’s ongoing involvement has been one of the more stable aspects of a season that has faced its share of scheduling surprises.

It’s important to note that the remaining cours beyond the first two have not been officially dated, leaving the back half of Season 4’s ambitious five cour run somewhat uncertain for fans trying to plan ahead. With the Rozzo conflict unresolved, Leon’s schemes in El Dorado simmering, and the arrival of a new Hero on the horizon, Episode 19 has a lot to cover. Which of these storylines are you most eager to see addressed when ‘That Time I Got Reincarnated as a Slime’ returns on August 21?
