Why this order?
"That Time I Got Reincarnated as a Slime" (Tensura) is one of the easiest big isekai to follow because its main television run is almost perfectly linear. The watch order below tracks the in-story timeline as Rimuru builds the monster nation of Tempest, so you only have one decision to make: where to slot the movie.
The default watch order is the one we recommend for everyone. Start with Season 1 (24 episodes, 2018-2019), which covers Rimuru's death, rebirth as a slime, and the founding of Tempest. Then watch Season 2, which aired in two cours: Part 1 in early 2021 (12 episodes) and Part 2 in mid-2021 (12 episodes), totaling 24 episodes built around the Walpurgis arc and Clayman's downfall. After Season 2, watch the canon theatrical film "Scarlet Bond" (2022), an original Fuse-supervised story set right after Season 2 that introduces Hiiro. Continue with Season 3 (24 episodes across two cours, 2024), which adapts the Holy Empire arc and Tempest's rise as a recognized nation. Finish with Season 4, which premiered in April 2026 and is currently airing as an unusually long five-cour run that picks up directly after Season 3.
The key gotcha is the film's placement. "Scarlet Bond" is technically a self-contained side adventure, but it slips in between Season 2 and Season 3 chronologically, so watching it before Season 3 gives you the cleanest continuity and avoids minor spoilers. It is not required to understand Season 3, but it is the intended order.
Two things are genuinely optional: the comedy spin-off "The Slime Diaries" (slice-of-life skits) and the various OVAs. If you enjoy lighter isekai like "KonoSuba" or kingdom-building shows like "Overlord" and "The Faraway Paladin," the Diaries are a fun palate cleanser, but they add nothing to the main plot.

Frequently asked questions
What order should I watch That Time I Got Reincarnated as a Slime in?
Watch Season 1, then Season 2 (Parts 1 and 2), then the canon movie Scarlet Bond (2022), then Season 3 (2024), and finish with the currently-airing Season 4 (2026). This follows the in-story timeline.
How many seasons and episodes are there?
There are four main seasons plus one theatrical film. Season 1 has 24 episodes, Season 2 has 24 (two cours), and Season 3 has 24 (two cours), for 72 across the first three seasons plus Scarlet Bond. Season 4 began airing in April 2026 as a long five-cour run and is still ongoing, so its episodes are still accumulating.
Is the Scarlet Bond movie canon, and when do I watch it?
Scarlet Bond is a Fuse-supervised story set right after Season 2. It is a self-contained side adventure but fits chronologically before Season 3, so watch it between Season 2 and Season 3.
Do I need to watch The Slime Diaries?
No. The Slime Diaries is an optional slice-of-life comedy spin-off with no bearing on the main plot. Skip it unless you want extra lighthearted Tempest content.
Was Season 2 split into two parts?
Yes. Season 2 aired as two cours in 2021 (Part 1 in winter, Part 2 in summer), each 12 episodes, for 24 total. Watch both as a single continuous season.
Is there a Season 4 of That Time I Got Reincarnated as a Slime?
Yes. Season 4 premiered on April 3, 2026 and is currently airing as the franchise's longest run yet, a five-cour season that continues the story directly after Season 3. It is the newest entry in the watch order.
