That Time I Got Reincarnated as a Slime the Movie: Tears of the Azure Sea (Japanese: 劇場版 転生したらスライムだった件 蒼海の涙編, Hepburn: Gekijōban Tensei Shitara Suraimu Datta Ken: Sōkai no Namida-hen) is a 2026 Japanese animated fantasy film based on the light novel series by Fuse. Produced by Eight Bit and distributed by Bandai Namco Filmworks, it is the second theatrical film in the franchise, following That Time I Got Reincarnated as a Slime the Movie: Scarlet Bond (2022).

The film features an original story written by Fuse and acts as a bridge between the third and fourth seasons of the television series. It is scheduled for a theatrical release in Japan on February 27, 2026, with a global rollout by Crunchyroll starting in April 2026.[2]

Plot

A month after the conclusion of the Tempest Founder's Festival, Rimuru Tempest and his companions accept an invitation from Elmesia El-Ru Sarion, the Celestial Emperor of the Magi Dynasty Salion, for a vacation at a private resort. Their peace is shattered by the arrival of Yura, a priestess from the undersea nation of Kaien, who seeks help to save her people.

The kingdom of Kaien, which worships the ancient Aqua Dragon, is being threatened by a mysterious pollution of the "Azure Sea" and a conspiracy to forcibly awaken the dormant deity. Rimuru and the Tempest executives must dive into the deep sea to uncover the plot and stop an invasion of the surface world.
