## TenSura Season 3's Final Cour Gets a Date — Fall 2026
Studio 8bit has officially confirmed that the second and final cour of *That Time I Got Reincarnated as a Slime* Season 3 will premiere in **Fall 2026**, completing the arc that began in the first cour earlier this year. The announcement was shared through the official TenSura social channels alongside a new key visual featuring Rimuru in Demon Lord form.
### What the Final Cour Will Cover
Season 3 is adapting the *Tempest* narrative arc from Fuse's light novel — the sequence in which Rimuru's political authority consolidates and the full consequences of his ascension to Demon Lord play out across Jura Tempest Federation's relationships with surrounding nations.
The final cour is expected to adapt the material dealing with:
- The **Great Demon Lord Council** and Rimuru's formal standing within it
- **Milim Nava's** shifting allegiances and the political destabilization of the western nations
- Clayman's full reckoning and the events of the Walpurgis gathering
- The aftermath chapters that reset the world order for the planned Season 4
The arc is one of the most plot-dense stretches of the source material, and the production's decision to split it across two cours gives the narrative room to breathe in a way earlier seasons occasionally struggled with.
### Production Notes
Director Atsushi Nakayama returns, as does the primary creative team that established the series' visual language across Seasons 1 and 2. Studio 8bit has made no announcements regarding animation staff changes for the final cour, which production sources describe as already substantially complete in storyboard form.
The new key visual — Rimuru standing against a sky of massed magical formation — is more explicitly political in its staging than earlier visuals, which foregrounded the isekai adventure tone. It is a deliberate signal about where the arc is headed.
### The Road to Season 4
With the light novel's narrative extending well beyond what Season 3 will adapt, an eventual Season 4 is broadly anticipated. No announcement has been made. The completion of Season 3 represents the adaptation reaching one of the novel's clearest structural stopping points — making a continuation a natural next project rather than a mid-arc decision.
For now, the Fall 2026 premiere of the final cour puts TenSura in the fall season alongside *Frieren* Season 2, a coincidence the fandom has noted with considerable enthusiasm.
