‘That Time I Got Reincarnated as a Slime’ Season 4 Episode 23 Release Date, Time, Where to Watch and What Comes Next for Rimuru

Rimuru Tempest is not slowing down, and neither is ‘That Time I Got Reincarnated as a Slime’ as it barrels toward the back stretch of its fourth season. The isekai favorite has kept fans locked into a weekly Friday rhythm for months, and the countdown to the next chapter is officially on.

With the Founder’s Festival politics still simmering and the Rozzo family circling Rimuru’s growing influence, this season has leaned hard into nation building drama layered over genuine combat stakes. Here is everything currently confirmed about when episode 23 drops, where to stream it, and what has been happening in the story so far.

Slime Season 4 Episode 23 Release Date and Time

Episode 23 of ‘That Time I Got Reincarnated as a Slime’ season 4 is scheduled to premiere on Friday, September 18, 2026, continuing the show’s established weekly cadence. This follows directly after episode 22, which was set to air on Friday, September 11, 2026.

For international viewers, the timing has stayed largely consistent. New episodes are set to premiere at 7 a.m. Pacific Daylight Time, 8 a.m. Mountain Daylight Time, 9 a.m. Central Daylight Time, 10 a.m. Eastern Daylight Time, and 2 p.m. Greenwich Mean Time.

The season has not been entirely without hiccups along the way. Season 4 previously saw one of its episodes bumped from a scheduled July 31 release to a later August date because of broadcast changes in Japan, a reminder that dates can shift even mid season. Still, the production has course corrected nicely and fans have enjoyed a steady stream of new content for months now.

Where to Watch the New ‘Slime ‘Tensura’ Episode?

Streaming access for this season has actually expanded compared to earlier entries in the franchise. Beyond Crunchyroll, the series has broadened its footprint, and ‘That Time I Got Reincarnated as a Slime’ season 4 can currently be streamed on both Netflix and Crunchyroll. That dual availability gives subscribers of either platform a legitimate way to keep up as new chapters land each week.

For fans who prefer buying episodes outright rather than maintaining a subscription, digital retail is also on the table. Digital retail options exist as well, with the season available to buy as a download through Amazon Video and the Apple TV Store, alongside the Crunchyroll Amazon Channel option.

New installments continue to arrive with strong accessibility for a global audience. New episodes of season 4 release on Fridays at 7 a.m. PT and 10 a.m. ET on Crunchyroll, arriving with English subtitles as well as an English dub. In Japan, the broadcast footprint remains wide. That Time I Got Reincarnated as a Slime is airing in Japan on Tokyo MX, MBS, BS11, TV Aichi, TVh, TVQ, GYT, GTV, TUF and AT-X.

On the Japanese broadcast side, the show maintains its usual home. The anime airs on NTV’s Friday Anime Night programming block, with new episodes releasing on Fridays at 7 a.m. Pacific Time and 10 a.m. Eastern Time on Crunchyroll.

Season 4’s Scope and What Rimuru Is Up Against

This fourth outing has quietly become the most ambitious the franchise has attempted. The series has been officially confirmed to run for 60 episodes total, split across five cours, with the first two cours airing back to back. That structure means the current stretch of episodes is only the first major wave of a much larger planned rollout.

The central conflict driving these episodes remains rooted in ideology rather than simple monster battles. After holding the Founder’s Festival and establishing diplomatic relations with various nations, the Jura-Tempest Federation begins moving toward realizing a world where humans and monsters can live together, called the Human-Monster Coexistence Sphere.

However, in the shadows, there are those who view the rise of Demon Lord Rimuru as a grave threat, with Granbell Rosso and his granddaughter Mariabell Rosso at the center of that opposition.

Fan reaction to the season has stayed largely positive even during its more dialogue heavy stretches. Viewer discussion has highlighted the show’s willingness to balance lighthearted character beats with weightier emotional payoffs, particularly around figures like Luminous Valentine, whose long buried guilt has become a genuine highlight of this run for longtime followers of the source material.

The Voice Cast Bringing the Story to Life

The season has retained its familiar lineup of talent, which has helped keep continuity strong for longtime viewers. Miho Okasaki is reprising her role as Rimuru Tempest, the protagonist of the series.

The supporting roster remains extensive as well. The cast also includes Anzu Haruno as Ramiris, Asuna Tomari as Gobta, Chikahiro Kobayashi as Ranga, Daisuke Ono as Granbell Rosso, Hōchū Ōtsuka as Hakurō, Inori Minase as Mariabell Rosso, Kanehira Yamamoto as Rigurd, and Lynn as Luminus Valentine.

The musical side of the production has also carried over familiar energy while introducing fresh material for this arc. Eir Aoi performs the opening theme song ‘Esoragoto (Unrealistic)’ while CiON performs the ending theme song ‘Katsubō (Craving)’.

With Granbell and Mariabell Rosso tightening their grip on the narrative and Leon still scheming from El Dorado, episode 23 has plenty of ground to cover before this cour wraps. Which side are you rooting for as Rimuru’s coexistence dream collides with the Rozzo family’s plans, and what do you think happens next for Tempest.
