That Time I Got Reincarnated as a Slime is set to continue its run well into 2027, following the conclusion of the fourth season's first half. The production committee confirmed that the second part of the current season is slated for a July 2027 premiere. Fans of the franchise won't have to wait long for new content, as a spin-off series, Tensei shitara Slime Datta Ken: Clayman Revenge, is scheduled to arrive earlier that spring in April 2027.
The spin-off adaptation focuses on the Marionette Master, Clayman, picking up after the events of the Walpurgis Festival. Studio 8bit continues its long-standing relationship with the franchise, handling the animation production for the new project. The staff includes director Kentarou Sugimoto, series composer Yuuji Haibara, and character designers Asumi Hashimoto and Hideki Sakai. The core voice cast from the main series is confirmed to return for this side story.
This expansion follows a massive run for the franchise, which began with the original light novel series by Fuse and Mitz Vah. While the main light novel concluded with its 23rd volume in 2025, the anime adaptation remains a cornerstone of the studio's output. The series maintains a strong presence on platforms like Crunchyroll, which has consistently simulcast the previous seasons.
Why it matters: With the main light novel series finished, the move toward spin-offs like Clayman Revenge suggests a shift in focus toward exploring side narratives within the established world. Given the studio's deep familiarity with the source material, it remains to be seen how these shorter-form spin-offs will balance the tone of the main series.
