That Time I Got Reincarnated as a Slime (2018–…) watch online

That Time I Got Reincarnated as a Slime (Japanese: 転生したらスライムだった件, Hepburn: Tensei Shitara Suraimu Datta Ken; lit. 'The Story of My Reincarnation as a Slime'), also known as Regarding Reincarnated to Slime and by the contraction TenSura (転スラ), is a Japanese fantasy anime television series based on the light novel series TenSura written by Fuse. Produced by Eight Bit, the series follows Satoru Mikami, a salaryman who is murdered and reincarnated in a fantasy world as a powerful slime named Rimuru Tempest.

Since its debut in 2018, the series has become a cornerstone of the Isekai genre, praised for its focus on nation-building and diplomacy rather than just combat. As of February 2026, the franchise has produced three television seasons, multiple OVAs, and two theatrical films. A fourth season, consisting of an unprecedented five-cour broadcast, premiered on April 3, 2026, following the release of the second film, Tears of the Azure Sea.
