That Time I Got Reincarnated as a Slime

This 2018 television anime matters because it turns a reincarnation premise into a story about community building. Across its 24 episode run, it mixes action and comedy with politics, economics, and a growing ensemble, so the appeal comes from alliances, negotiations, and watching a strange new society take shape.

The experience is generous and approachable. Viewers who like fantasy adventures with a likable lead, monster allies, found family moments, and a steady blend of jokes and swordplay will find an easy entry point. The English dub and broad streaming availability lower the barrier further.

For newcomers to isekai, this work offers a clear emotional hook: an ordinary person gets a second chance and chooses to build something with others. Its civic and strategic threads may appeal to viewers who want more than a simple combat loop, while the ensemble keeps the world feeling social rather than solitary.

That Time I Got Reincarnated as a Slime (転生したらスライムだった件, commonly shortened to TenSura) is a 24-episode television anime produced by the studio Eight Bit. It adapts the light novel series written by Fuse. The series aired in Japan beginning in the fall 2018 season, running from October 2, 2018 to March 19, 2019, with each episode lasting roughly 24 minutes.

The story centers on Satoru Mikami, a 37-year-old office worker who is killed and reincarnated in a fantasy realm as a slime monster. Under the name Rimuru Tempest, he gathers allies among monsters and works to establish a nation of his own, giving the adaptation a blend of action, comedy, and political maneuvering. An English dub was produced, and the series reached viewers through streaming services including Crunchyroll, Funimation, Hulu, and Amazon Prime Video.

This 24-episode television series is the opening anime adaptation of the TenSura franchise, which began as a light novel series written by Fuse. It adapts the earliest portion of that source material, introducing Rimuru Tempest and the founding of the Jura Tempest Federation, and it serves as the entry point for viewers who approach the story through animation rather than prose or comics. It is neither a spin-off nor an alternate retelling, but the primary animated telling of the story's opening arc.

Everything animated that follows builds outward from this season. The main television line continued with later seasons, while the wider franchise expanded into OVAs, the Slime Diaries spin-off, and theatrical features such as Scarlet Bond and Tears of the Azure Sea. Manga adaptations, side-story comics, and video game titles run alongside the anime, sharing characters and setting rather than replacing one another. Later seasons continue the narrative well past the events covered in these 24 episodes, so this entry remains one installment within a much larger and still-growing whole.
