About TV Anime That Time I Got Reincarnated as a Slime
A new life as a slime begins. Satoru Mikami, an ordinary office worker, is stabbed by a random attacker and wakes up in another world — but as a slime. Taking on a new life as Rimuru, he is thrust into a world teeming with various races, and sets out to build a nation where all peoples can live happily together.
The TV anime is based on the manga adaptation (serialized in Kodansha's Monthly Shonen Sirius, manga by Taiki Kawakami) of the novel of the same name by Fuse, originally published on the novel-posting site "Shosetsuka ni Naro." The series — including related publications — has surpassed a cumulative print run of 40 million copies as of February 2023. Season 1 aired in 2018 to 2019. The second theatrical film, 劇場版 転生したらスライムだった件蒼海の涙編, screened in February 2026, and Season 4 of the TV anime is currently airing.
