The official website of the Tensei shitara Slime Datta Ken (That Time I Got Reincarnated as a Slime) anime series announced on Sunday that its second season will air in two cours. The first half will debut in October 2020, with the second half in April 2021. The website also revealed the first promotional video.
Bandai Namco Arts simultaneously announced a television anime adaptation of Shiba's Tensura Nikki: Tensei Shitara Slime Datta Ken (The Slime Diaries: That Time I Got Reincarnated as a Slime) spin-off manga. The anime will air from January to March 2021.
Both the main television series and the spin-off anime will premiere on Tokyo MX, MBS, BS11, TV Aichi, TV Hokkaido, TVQ Kyushu Broadcasting, Tochigi TV, and Gunma TV. This marks nine consecutive months of new Tensei shitara Slime Datta Ken anime installments that will broadcast on television. The first season will begin rerunning on the aforementioned channels—with the exception of Tokyo MX and MBS—on April 14.
