That Time I Got Reincarnated as a Slime: Is It Worth Watching?
TL;DR — Yes, if you want a relaxed, feel-good fantasy. A man reincarnated as a slime becomes ridiculously powerful early on, so the appeal isn't tense fights but building a nation, recruiting monsters and making allies. Three seasons (72 episodes) are out, Season 4 aired its first two parts from April to September 2026, and a third part is due in July 2027.

Take the quizThe verdict
Worth it if you want comfort rather than suspense. Rimuru becomes overpowered almost immediately, so don't expect nail-biting fights. The pleasure is watching a ragtag group of goblins, ogres and wolves turn into a thriving, multi-species country, and seeing a kind, practical leader win people over.
The premise
Satoru Mikami, a 37-year-old office worker, is stabbed and dies, then wakes up in a fantasy world as a slime. He can absorb anything he eats and copy its abilities. Renamed Rimuru Tempest, he befriends a sealed dragon, takes in monsters who need protection, and slowly builds a nation that the human kingdoms and demon lords around him have to reckon with.
Watch order
- Season 1 (2018-2019, 24 episodes).
- Season 2 (2021, 24 episodes in two parts). The Slime Diaries, a gentle 12-episode comedy spinoff, aired between the two parts and is optional.
- Scarlet Bond (film, 2022). Optional side story.
- Season 3 (2024, 24 episodes).
- Tears of the Azure Sea (film, 2026). Optional side story set after Season 3, now on Crunchyroll.
- Season 4 (from April 3, 2026). Planned in five parts: the first two aired through September 25, 2026, the third is due in July 2027.
What people like and dislike
Fans love the warmth, the huge cast of loyal companions and the satisfying sense of a community growing. The common complaints are low tension, because Rimuru rarely loses, and Season 3's heavy focus on meetings and politics, which some viewers find slow.
Who it suits
If you liked Ascendance of a Bookworm or the calmer stretches of Overlord, you'll probably enjoy this. If you want danger and stakes in your isekai, try Re:Zero instead.
Frequently asked questions
Do I need to watch the Slime movies? No. Scarlet Bond (2022) and Tears of the Azure Sea (2026) are standalone side stories.
Is Slime a good first isekai? Yes, if you want something light and upbeat. It has battles, but the heart of it is friendship and nation-building.
