Tensura Season 4 Cour 3 Release Date Set for July 2027

That Time I Got Reincarnated as a Slime Season 4 now has a confirmed return window for its third cour. The official Tensura site announced on September 25, 2026 that Season 4 Cour 3 will begin broadcasting in July 2027. An exact premiere day has not been announced yet.

The same announcement also revealed a second Tensura TV project for 2027: That Time I Got Reincarnated as a Slime: Clayman’s Revenge will begin airing in April 2027. It is a separate spin-off anime, not Season 4 Cour 3, so viewers will effectively get new Tensura television anime in spring and summer 2027.

This is a substantial update from the earlier Season 4 status. The fourth season was already confirmed as a five-cour production, with its first two cours airing consecutively in 2026. The July 2027 announcement now gives fans the first firm window for the next block of episodes after that initial run.

Tensura Season 4 Cour 3 Release Date

Tensura Season 4 Cour 3 is officially scheduled for July 2027. The production committee has not announced the exact July date, episode count for the third cour, or the broadcast schedule for the fourth and fifth cours.

Season 4 began on April 3, 2026. Its second cour started on July 3, continuing the initial back-to-back two-cour run. The overall season was announced as five split cours, making it an unusually long television project rather than a conventional one- or two-cour sequel.

That distinction matters for searchers looking for a single Season 4 end date. There is not one continuous 2026-to-2027 broadcast. The first two cours form the initial 2026 block, Cour 3 returns in July 2027, and later cour dates remain unannounced.

What Was Confirmed on September 25?

The official Tensura announcement confirmed two separate television plans. First, Season 4 Cour 3 will air from July 2027. Second, the Clayman’s Revenge manga is receiving its own TV anime beginning in April 2027.

The announcement was accompanied by a special collaboration video featuring newly animated material from Eight Bit. The video connects the main series and the new spin-off promotionally, but it does not merge their stories into one season.

The key confirmed schedule is:

• That Time I Got Reincarnated as a Slime Season 4 Cour 3: July 2027
• That Time I Got Reincarnated as a Slime: Clayman’s Revenge: April 2027
• Season 4 Cour 4 and Cour 5: release windows not yet announced

Anything more precise than those windows should be treated as unconfirmed until the production committee publishes a date, television slot, or new promotional video.

How the Five-Cour Season 4 Structure Works

Season 4 was announced as a five-cour production, with the first two cours airing consecutively from April 2026. A cour is a roughly three-month television programming block, so five cours gives Tensura much more room than a standard sequel season.

That format also explains why the July 2027 announcement is for Cour 3 rather than a newly numbered Season 5. It remains part of Season 4 even though there is a sizable break after the second cour.

The first 2026 block moved Tensura beyond the Founding Festival and deeper into the political conflicts surrounding Tempest. Rimuru’s growing influence, the Council of the West, Granville and Maribel Rosso, Chloe, Hinata, Leon, and the Primordial demons all became increasingly important as Tempest stopped being a regional curiosity and became a force other nations had to account for.

By the second cour, Testarossa, Carrera, and Ultima were no longer merely future light-novel names for anime viewers. The anime brought the three Primordials into the center of the story, meaning this article no longer needs to frame their involvement as a prediction.

What Will Season 4 Cour 3 Cover?

The production committee has not yet published an official story synopsis for Cour 3, so its exact light-novel endpoint should not be presented as confirmed. Tensura can rearrange explanations, side material, and scene order even when the broad adaptation path follows the novels.

What is safe to say is that Cour 3 continues the same Season 4 production rather than resetting the story. The first two cours expanded Tempest’s political and military reach and pushed several long-running character threads forward. Cour 3 will pick up after those events when the anime returns in July 2027.

Anime-only viewers should be cautious with volume-by-volume predictions circulating online. Those can reveal future opponents, evolutions, alliances, or outcomes before the anime itself has established them. Until a Cour 3 trailer or official synopsis arrives, the exact arc breakdown remains an adaptation estimate rather than confirmed anime information.

Why the Three Primordials Still Matter

Testarossa, Carrera, and Ultima were central to the older version of this article because their arrival represented a major change in Tempest’s power structure. That remains useful context, but their role is no longer hypothetical.

All three are Primordial demons, ancient beings identified by colors. Diablo, the Primordial Black, serves Rimuru first and later brings three other Primordials into Tempest’s orbit. Rimuru names them and gives them positions that let his nation project influence far beyond his own personal presence.

Testarossa, the Primordial White, combines enormous magical power with unusual political composure. That makes her particularly valuable in diplomatic or strategic situations where brute force would create more problems than it solves.

Carrera, the Primordial Yellow, is associated with overwhelming destructive power. Her value to Tempest is straightforward: she represents the kind of deterrent that can change an enemy’s planning before a battle even begins.

Ultima, the Primordial Violet, is more unpredictable and ruthless. She is dangerous not just because of magical strength but because she is comfortable using methods that more conventional fighters would avoid.

The important point is not a simplistic strongest-to-weakest ranking. Rimuru gains three specialists who can operate independently, lead missions, represent Tempest, and respond to threats without requiring him to personally solve every crisis. That is a sign of Tempest becoming a durable power rather than a nation built around one overpowered ruler.

What Is Clayman’s Revenge?

Clayman’s Revenge is a separate Tensura spin-off based on the manga by Wataru Kajika, with the original concept connected to series creator Fuse. The official site describes it as an official 'revenge' work built around Clayman getting another chance after his defeat.

Its television anime begins in April 2027, three months before Season 4 Cour 3’s announced July window. The spin-off uses Clayman as its central character and explores an alternate route built around him trying to redo his life differently.

The September 25 announcement also confirmed that Eight Bit created new animation for the collaboration video connecting the two 2027 projects. The separate Clayman’s Revenge announcement published a teaser visual and main staff information.

For viewers following only the main Rimuru story, the most important distinction is simple: Clayman’s Revenge is not required to turn Season 4 into Cour 3. It is its own TV anime project within the wider Tensura franchise.

Is Clayman’s Revenge Season 5?

No. Clayman’s Revenge is not Tensura Season 5 and it is not Season 4 Cour 3. The main anime remains in Season 4, while Clayman’s Revenge is a spin-off television adaptation.

The close scheduling can make the 2027 lineup look confusing: Clayman’s Revenge arrives in April, then the main series returns with Season 4 Cour 3 in July. Treating them as separate shows is the clearest way to follow the release calendar.

Where Will Tensura Season 4 Cour 3 Stream?

Crunchyroll has carried That Time I Got Reincarnated as a Slime Season 4 internationally during the 2026 run. The September 25 official announcement focused on the Japanese July 2027 broadcast window and did not provide a new region-by-region streaming schedule for Cour 3.

A continued international rollout on existing platforms would be unsurprising, but it should not be treated as newly confirmed for every territory until Crunchyroll or the production committee publishes the 2027 streaming details. This page will need another update when that information is announced.

What Is Still Unannounced?

The July 2027 window resolves the biggest question about when the main anime returns, but several details remain open:

• The exact July 2027 premiere date for Season 4 Cour 3
• The Cour 3 episode count
• The full Cour 3 trailer, opening and ending themes
• International streaming details for the 2027 return
• Release windows for Season 4 Cour 4 and Cour 5

Those are meaningful future update triggers. A new AnimeSparks URL is not necessary for each one because this existing Season 4 page already answers the same core release-status query.

The Short Answer

Tensura Season 4 Cour 3 is officially coming in July 2027. The exact day has not been announced. Season 4 remains a five-cour production, while Clayman’s Revenge is a separate spin-off TV anime premiering in April 2027.

For now, the cleanest 2027 Tensura schedule is Clayman’s Revenge in April followed by the main Season 4 story returning in July. Cour 4 and Cour 5 remain undated.
