Slime Season 4 Returns July 2027, Clayman Spinoff Arrives April

That Time I Got Reincarnated as a Slime season 4 will resume for its third part in July 2027, extending the franchise's already sprawling timeline. But before Rimuru's story picks back up, a spinoff titled Clayman's Revenge will debut in April 2027—and yes, it's exactly what the title promises.

The spinoff, directed by Kentarō Sugimoto at 8-Bit, centers on Clayman, the demon lord antagonist from the main series. Takehito Koyasu returns to voice the character, bringing continuity to a figure whose ambitions have defined much of the show's conflict. The premise alone signals a tonal shift: rather than following Rimuru's steady ascent, Clayman's Revenge pivots to explore the antagonist's perspective—a move that either deepens the world or indulges a villain's fantasy, depending on execution.

The staggered release schedule is deliberate. Clayman's Revenge arrives first in April, giving fans a four-month runway before season 4's third part lands in July. For a franchise this sprawling, the spinoff functions as both a palate cleanser and a strategic hold on audience attention. It's the kind of move that works only if the character has enough depth to sustain a full series—and Clayman, as a recurring schemer with genuine grievances against the protagonist, at least has the bones for it.

The Slime franchise has proven durable enough to justify this kind of expansion. The main series has already run for four seasons, and the spinoff suggests the studio sees room to mine the supporting cast and antagonist roster for additional stories. Whether Clayman's Revenge becomes a genuine exploration of a complex villain or a self-indulgent detour remains to be seen. Either way, the franchise is betting that audiences will follow.
