That Time I Got Reincarnated as a Slime has grown from a light novel phenomenon into one of the most influential Isekai anime franchises of the modern era. Through multiple anime seasons, OVAs, spin-offs, and a successful prior feature film, the story of Rimuru Tempest has captivated audiences with its blend of world-building, fantasy action, political strategy, and surprisingly heartfelt character relationships. Now, the series is ready to expand once again with a brand-new 2026 movie titled Tears of the Azure Sea, bringing fans back into the world of Tempest with an entirely new cinematic journey.
The announcement has generated huge excitement, especially with the release of the film’s first trailer and poster. As more and more Isekai titles release each year, only a handful manage to reach a level of global recognition large enough to justify multiple seasons and films. Reincarnated as a Slime remains one of the rare exceptions—an Isekai that not only survived the genre explosion but helped define it. With a new movie, a confirmed fourth season, and long-standing worldwide popularity, the franchise is set to enter another major chapter.

What Is “That Time I Got Reincarnated as a Slime: Tears of the Azure Sea” About?
Tears of the Azure Sea presents an original story crafted by the series’ author, Fuse, ensuring authenticity and canon-consistent storytelling. Set shortly after the events of the anime’s major political milestones, the film follows Rimuru and his closest allies as they accept an invitation to the luxurious private island of the Magi Dynasty Salion, ruled by the Celestial Emperor Hermesia.
While intended as a relaxing getaway following the opening of the Demon Kingdom Federation Tempest, the vacation quickly turns into a tense and mysterious confrontation. The peaceful atmosphere is disrupted by the arrival of a mysterious woman named Yura, whose appearance signals a new crisis rising from beneath the brilliant blue sea. A deeper conspiracy awaits Rimuru and company as they uncover hidden secrets tied to Salion, the oceanic setting, and forces not previously seen in the anime.
This movie’s narrative blends tropical scenery, magical politics, powerful new enemies, and world-expanding lore—giving fans a story that feels different in tone while maintaining strong ties to the existing plot.

Production & Development
