The highly anticipated fourth season of That Time I Got Reincarnated as a Slime officially premiered on Friday, April 3, 2026, marking the start of what is poised to be the series’ most extensive narrative undertaking to date. Crunchyroll has confirmed that the new season is slated for an expansive 60-episode run distributed across five cours, with the first two segments airing consecutively through September 11, 2026.
Expanding the Scope: A 60-Episode Narrative Commitment
This massive episode count represents a significant shift in production scale for the franchise. The series, which follows the journey of corporate worker-turned-slime Rimuru Tempest, is moving beyond its previous seasonal models to accommodate a denser, more complex storyline adapted from the light novels by Fuse. The first 24 episodes are scheduled to air in a continuous block, ensuring consistent weekly updates for the global audience every Friday at 7:00 a.m. PT/10:00 a.m. ET.
Conflict and Character Arcs in Season 4
The narrative stakes have escalated as the prosperity of the Tempest nation draws unwanted attention. The central conflict of the new season focuses on the ideological clash between Rimuru and the Rozzo family—specifically Granville and Maribel Rozzo—who advocate for a rigid structure to protect humanity by exerting control over it. Simultaneously, the plot expands to the region of El Dorado, where Demon Lord Leon is pursuing independent, high-stakes objectives. Returning director Naokatsu Tsuda and the team at studio 8bit have integrated these shifting power dynamics to heighten the series’ political intrigue.
Production and Global Availability
The production maintains continuity with the core creative team, featuring Miho Okasaki reprising her role as the voice of Rimuru Tempest. Musical contributions include the new opening theme “Esoragoto (Unrealistic)” by Eir Aoi and the ending theme “Katsubō (Craving)” by CiON. The anime is currently streaming across North America, Europe, Africa, the Middle East, and Southeast Asia via Crunchyroll, while Japanese viewers can access the series through NTV’s “Friday Anime Night” block.
The commitment to a 60-episode arc suggests that studio 8bit is prioritizing a faithful and unhurried adaptation of the source material, signaling that the franchise is moving into a phase of structural world-building rather than brief, episodic adventures.
