Overview
That Time I Got Reincarnated as a Slime Season 2 is the 2021 continuation of the anime adaptation of Fuse's light novel series, and this first part of twelve episodes marks the point where the story moves well past one monster's personal survival project. Rimuru's growing alliance now has to behave like a nation, which means diplomacy with neighboring powers, strained relations between monsters and humans, and decisions that carry weight beyond a single fight. For viewers already invested in the premise, this is where the series starts paying off its long build of skills, allies, and territory in a larger political frame.
The experience here is deliberately uneven in the best sense. Broad comedy and creature-taming warmth sit beside revenge, tragedy, war, and a genuinely menacing demonic threat, with an ensemble cast carrying much of the emotional load rather than the protagonist alone. Kingdom management and negotiation sequences give the action a context, so battles feel like consequences rather than set pieces. The season also leans into darker material than its premise might suggest, and it expects the audience to keep up with a widening roster of factions.
Because it is the first half of a split second season, it is not a natural starting point. Newcomers should begin with the earlier season, while returning viewers will find the English dub and a very broad streaming footprint across Crunchyroll, Netflix, Hulu, Bilibili, and YouTube make catching up straightforward. Anyone drawn to isekai that grows into ensemble governance and political fantasy, with a monstrous cast and a protagonist who prefers talking before fighting, will find this a rewarding stretch of the larger story.
Synopsis
This installment of That Time I Got Reincarnated as a Slime covers the first part of the series' second season, following Rimuru Tempest, a former office worker reborn in a fantasy world as a slime. Having built the Jura Tempest Federation into a home for goblins, ogres, lizardmen, and other displaced monsters, Rimuru now spends less time fighting for survival and more time governing: managing trade, settling disputes, and keeping a young nation fed, defended, and diplomatically viable.
The cast widens considerably as Rimuru's responsibilities grow. His loyal cabinet, including the ogre warrior Benimaru, the secretary Shion, the strategist Souei, and the craftsman Kaijin, helps run Tempest while he travels abroad. Diplomatic visits bring him back into contact with King Gazel Dwargo of the armed nation Dwargon and with the beast kingdom of Eurazania, whose leaders test whether a monster state can be treated as a legitimate partner. Familiar allies and mischievous demon lords such as Milim Nava keep the tone lively, but each new relationship also carries obligations that pull Rimuru further into world affairs.
The central conflict is the widening friction between monsters and humans. As Tempest's influence spreads, powerful human institutions and rival demon lords view the young federation as a threat worth containing, and Rimuru finds himself facing adversaries whose motives and methods he cannot simply overpower. Forced to weigh the ideals he brought from his old life against the harsh expectations of this world, he must decide how far he is willing to go to protect the people who now depend on him.
Watch Episode 1
Should You Watch It?
Watch it if you enjoy
- You followed Rimuru's first season and want the payoff: Tempest moves from survival to running and defending a nation.
- You enjoy kingdom management, trade, negotiation, and diplomacy threaded through fantasy action.
- You like ensemble casts where Benimaru, Shion, Souei, and Kaijin carry as much of the story as the protagonist.
- You want a fantasy that pairs creature-taming warmth and broad comedy with darker political stakes.
It may not suit you if
- You want a self-contained story; this is the first cour of a split second season and continues directly from season one.
- You prefer fast, focused pacing; governing, trade, and negotiation sequences take up real screen time here.
- You dislike sharp tone swings between comedy and material like revenge, tragedy, and war.
- You find a widening roster of factions, demon lords, and allies hard to keep straight.
This automatic starting point balances the series length, pacing, time commitment, and available Volluble research data. Editors can override it when firsthand knowledge suggests a better entry point.
Why It Connects With Audiences
Why people love it
- The turn toward governing — settling disputes, managing trade, keeping Tempest fed and defended — gives later battles a sense of consequence.
- Found-family warmth among goblins, ogres, lizardmen, and other displaced monsters remains a central draw.
- Returning allies and mischievous demon lords such as Milim Nava keep the lighter side lively between heavier arcs.
- Studio Eight Bit's production is rounded out by 'Storyteller' by True and 'Storyseeker' by Stereo Dive Foundation.
Common criticisms
- The pandemic-era delay pushed this cour from its planned October 2020 premiere to January 2021, a disruption fans noted at the time.
- As the first half of a split season, much of this cour sets up conflicts that only resolve in the later part.
- For some, the mix of broad comedy with revenge, tragedy, and war sits unevenly across episodes.
- A steadily expanding cast and faction list can make the political threads harder to follow for casual viewers.

Production Background
This entry covers the first cour of That Time I Got Reincarnated as a Slime Season 2, a twelve-episode television anime produced by studio Eight Bit. The series adapts the light novel written by Fuse and illustrated by Mitz Vah, the same source material that grounds the broader franchise. Season 2 was announced as a split-cour production, and this first part aired from January 12 to March 30, 2021, during the Winter 2021 season.
The season's rollout was reshaped by real-world production circumstances. The first part had originally been scheduled to premiere in October 2020, but it was delayed to January 2021 because of production complications resulting from the COVID-19 pandemic. The later second part was likewise pushed back, moving from April to July 2021. That scheduling shift makes this cour a notable example of how pandemic-era disruptions affected anime production timelines.
Music and distribution rounded out the release. The first opening theme, "Storyteller," was performed by True, while the first ending theme, "Storyseeker," was performed by Stereo Dive Foundation. The work received an English dub and became available through multiple streaming services, including Crunchyroll, Netflix, Hulu, YouTube, and Bilibili.
Franchise Context
That Time I Got Reincarnated as a Slime Season 2 is the second television season of the anime adaptation of Fuse and Mitz Vah's light novel series. It continues the story of Rimuru and the Jura Tempest Alliance after the events of the first season, rather than serving as a reboot or side story. The season was produced by Eight Bit and aired in two parts in 2021: the first run from January to March, and the second from July to September.
Within the larger franchise, this entry sits alongside the original light novels, manga adaptations, spin-offs, films, and games. The official portal lists many related comics and novels, including diary and alternate-perspective titles, plus theatrical features and console games. Season 2 is therefore a main-line anime installment, not a stand-alone work. It adapts material from the novels and follows the first anime season. Viewers seeking the full narrative should treat it as a continuation, while the broader franchise hub covers the other branches and media.
