That Time I Got Reincarnated as a Slime the Movie: Tears of the Azure Sea

That Time I Got Reincarnated as a Slime the Movie: Tears of the Azure Sea is a 2026 Japanese animated fantasy film from the light novel series by Fuse. Animated by Eight Bit and released by Bandai Namco Filmworks, it's the franchise's second movie, coming after *Scarlet Bond* (2022). The story, written by Fuse, is original and connects the third and fourth seasons of the TV show.

In the underwater kingdom of Kaien, a woman named Yura steals a magical flute called the Dragon's Fang and escapes. A month after the Tempest Founder's Festival, Rimuru Tempest and his friends accept a vacation invitation from Emperor Elmesia El-Ru Sarion of the Sorcerous Dynasty Thalion. Rimuru learns that nuclear magic attacks aimed at Leon Cromwell's domain keep missing, hitting Kaien instead, though a force field protects it. Yura reaches an island and meets Gobta. They fight off men sent by minister Djeese to retrieve the flute, but lose it in the escape. Zodon brings the flute to Djeese, who plans to awaken the city's mystical water dragon and control it to attack the surface.

Rimuru and company meet Yura and learn Kaien's ancient history. Half the group heads to Kaien, but Djeese and the water dragon ambush them. During the fight, Yura catches the lost flute. Djeese seems eaten by the dragon as it leaves. Yura returns to Kaien to put the flute back, with Rimuru, Shion, Ranga, and Gobta following. The flute breaks, making the dragon vanish. After touring Kaien, the group stays the night.

Djeese survived, but Zodon kills him, having used him all along. Zodon captures Yura, puts her in a trance, and plans to marry her to conquer the world—Yura is a key part of the water dragon. The revived dragon attacks the resort island and raises Kaien to the surface, summoning clones. As Rimuru and friends fight, Gobta frees Yura. Rimuru kills Zodon with a powerful sky attack.

The next day, Gobta confesses his love, but Yura says she has no romantic interest and leaves; they stay friends. Back in Kaien, Yura reveals she isn't just the dragon's core controller—she *is* the core, reborn many times, and dissolves into bubbles. Gobta hopes to see her again. In a post-credits scene, an egg washes ashore and a baby water dragon hatches. Meanwhile, Diablo defeats the primordial Jaune, who learns he works for Rimuru and becomes interested in him.
