That Time I Got Reincarnated as a Slime Watch Order September 2026
Newcomers get tripped up by two side pieces: The Slime Diaries is an optional slice-of-life spin-off set back during the Season 1 timeframe (not a plot continuation), and the Scarlet Bond movie is canon-recommended and slots in AFTER Season 2 but BEFORE Season 3. Season 2 also confuses people because it aired as a split cour (Part 1 in early 2021, Part 2 in mid-2021), with The Slime Diaries airing in between. Below is the full recommended That Time I Got Reincarnated as a Slime watch order for September 2026, cross-checked against multiple community guides — plus alternative orders and what you can safely skip. Last verified September 1, 2026.

🔀 Alternative orders
Chronological (incl. Slime Diaries & OVAs)
If you insist on story-timeline order, The Slime Diaries and the 'Life as a Teacher' OVAs slot into the Season 1 timeframe, and the 3-episode 'Visions of Coleus' / Coleus's Dream OVA sits around the Season 2 period. Most guides advise against this — release order preserves plot twists and is simpler.
S1 (with Teacher OVAs & Slime Diaries woven in) → S2 Part 1 → Visions of Coleus OVA → S2 Part 2 → Scarlet Bond → S3
⏭️ What can you skip?
The Slime Diaries (slice-of-life spin-off) is skippable; the 'Life as a Teacher' and 'Visions of Coleus' / Coleus's Dream OVAs are optional; Scarlet Bond is canon-recommended and worth watching before S3.
📺 Where to stream
- Crunchyroll (all seasons, spin-off, OVAs and the Scarlet Bond movie, sub & dub)
❓ FAQ
Where does the Scarlet Bond movie go?
After Season 2 and before Season 3. It's a self-contained feature set following the Season 2 events; guides place it as the bridge into Season 3.
Is The Slime Diaries canon / do I need it?
It's an optional slice-of-life spin-off set back during the Season 1 'peaceful early days' timeframe. It's low-stakes comedy that doesn't move the main plot, so it's fully skippable — enjoy it as a bonus, not a requirement.
Is the movie required before Season 3?
Not strictly required to follow Season 3, but strongly recommended. Scarlet Bond is treated as canon-adjacent by most guides and is the natural viewing step between S2 and S3.
How many episodes total?
The core TV run is 24 (S1) + 24 (S2, as 12+12) + 24 (S3) = 72 episodes, plus the Scarlet Bond movie. Add the optional 12-episode Slime Diaries and the short OVAs (Teacher, Visions of Coleus) if you want everything.
Where can I stream it?
Crunchyroll carries all seasons, The Slime Diaries, the OVAs, and the Scarlet Bond movie (subbed and dubbed) — the one-stop platform for the whole franchise.
Is there a Season 4 (or a second movie)?
Yes — as of August 2026 the franchise has expanded on both fronts: the second film, 'Tears of the Azure Sea,' opened in Japan on February 27, 2026, reached US/Canada theaters on May 1 and started streaming on Crunchyroll on July 31, 2026; Season 4 began streaming April 3, 2026 on Crunchyroll as an unprecedented five-cour run. These come after Season 3 in both release and story order.
