That Time I Got Reincarnated as a Slime Season 4 has cleared its Episodes 73-84 stretch, and the question every returning viewer is asking is simple: does the slime still hold up now that Rimuru is basically a demon lord running a country? Here's the honest read, plus where to stream it.
Quick answer
That Time I Got Reincarnated as a Slime (*Tensei shitara Slime Datta Ken*) Season 4 is the Eight-Star Demon Lords / nation-building arc, animated by studio Eight Bit. It streams on Crunchyroll (sub and dub). According to SenpaiRanks, Season 4 holds an adjusted 7.69, while the franchise as a whole sits at 7.99 — both firmly in the upper isekai tier. Per SenpaiRanks, Slime is one of the genre's few long-runners whose ranking hasn't decayed across four seasons.
The read on Season 4
Season 4 is where Slime stops being an underdog isekai and becomes a geopolitics show — treaties, alliances, and Tempest's place among the demon lords. On SenpaiRanks that shift shows up in the split: the Consensus axis stays high because the fanbase is loyal, while the Quality axis dips slightly versus the combat-forward Season 2 peak. That's the honest nuance a single MyAnimeList number flattens — Season 4 is a 7.69, a notch under the franchise's 7.99, and our dual-axis board tells you it's the pacing, not the polish, that moved. Stack it against Mushoku Tensei and Shangri-La Frontier Season 3 on the best summer 2026 isekai board.
Is Season 4 good?
If you're here for Rimuru's power growth and the widening cast, yes — Season 4 delivers the payoffs the earlier seasons set up. If you preferred the tighter, dungeon-scale stakes of Season 1, the diplomacy-heavy arc will feel slower. Either way it stays comfortably above the isekai median. It rewards viewers already invested in Tempest; it is not the place to start the franchise.
Where to watch
Every season, including Season 4, streams on Crunchyroll with subtitles and an English dub — platform-neutral fact: it's a Crunchyroll exclusive in most regions, not on Netflix or Prime Video.
