Introduction
The appeal of That Time I Got Reincarnated as a Slime goes well beyond watching Rimuru become powerful. Rimuru begins a new life as a slime, but the series gradually turns that individual progression into something much larger: new allies, different races living together, an expanding community, and eventually the growth of Tempest itself.
That makes searching for anime like That Time I Got Reincarnated as a Slime more specific than simply looking for another isekai with an overpowered protagonist. You may want Rimuru’s early monster progression, the satisfaction of watching Tempest develop, the political side of running a nation, or simply the quieter moments when its residents build a place worth living in.
These five anime approach those strengths from different directions. The goal is to help you decide which part of the Slime experience you actually want next, with all comparisons kept spoiler-free.
Quick List: Best Anime Like That Time I Got Reincarnated as a Slime
- TSUKIMICHI -Moonlit Fantasy- — Start here if you want another powerful isekai protagonist surrounded by nonhuman allies and a steadily growing community.
- So I’m a Spider, So What? — Choose this if Rimuru’s early monster evolution and constant skill progression were your favorite parts.
- How a Realist Hero Rebuilt the Kingdom — Best if Tempest’s administration, economics, leadership, and diplomacy interested you more than its battles.
- Overlord — Pick this for an overwhelmingly powerful ruler, loyal nonhuman followers, and expanding political influence with a much darker tone.
- Farming Life in Another World — Best if you mainly enjoyed watching Tempest become a comfortable, functioning place where more people could live together.
1. TSUKIMICHI -Moonlit Fantasy-
The Closest Match for Tempest’s Growing Community
Makoto Misumi is summoned to another world, but his journey quickly moves away from the standard heroic path. As he explores the fantasy setting, his unusual strength brings him into contact with powerful nonhuman characters and a community begins forming around him. Crunchyroll’s official series description confirms the basic setup of Makoto being summoned to a fantasy world.
For Slime fans, the important similarity is not simply that Makoto is strong. Like Rimuru, his growing influence creates relationships, settlements, and opportunities that make the world around the protagonist feel increasingly important.
If You Liked Rimuru as a Socially Minded Powerhouse
Rimuru rarely feels like an isolated power fantasy. Much of the enjoyment comes from seeing what happens when overwhelming ability is combined with alliances, trade, friendships, and a growing group of people who depend on the protagonist.
TSUKIMICHI provides a comparable balance of action, comedy, powerful companions, and expanding social connections. It is the easiest transition on this list if you want several Slime qualities at once rather than one very specific feature.
The Biggest Difference
The community-building element does not develop in exactly the same way as Tempest’s nation-building. Slime spends more time turning its settlement into a political entity with increasingly formal relationships between different powers.
If meetings, government, and diplomacy were your favorite parts, How a Realist Hero Rebuilt the Kingdom is the more focused choice.
2. So I’m a Spider, So What?
If Rimuru’s Early Evolution Was the Best Part
A high school girl is reincarnated as a spider inside a dangerous dungeon and has to survive using the abilities available to her. That monster-reincarnation premise is central to Crunchyroll’s official description of the series.
This makes So I’m a Spider, So What? the strongest recommendation for viewers who miss early Slime, when discovering a new ability could immediately change what Rimuru was capable of doing.
The satisfaction comes from progression itself: surviving difficult situations, understanding new skills, and gradually becoming capable of handling challenges that initially seemed overwhelming.
What This Anime Does Differently
Rimuru’s progression eventually becomes community progression. His abilities help create relationships, protect allies, and expand Tempest.
This series stays much more focused on personal survival and individual development. You get more of the “what ability comes next?” feeling, but much less of the city-building and diplomacy that define later parts of Slime.
Skip This One If
If your favorite episodes involved Tempest’s residents, construction, international relationships, or day-to-day community life, this may feel too focused on individual progression.
Choose it first only if monster evolution was the part of Slime you most want to experience again.
3. How a Realist Hero Rebuilt the Kingdom
If Tempest’s Government Was More Interesting Than Its Battles
Kazuya Souma is summoned to a fantasy world and unexpectedly placed in charge of a kingdom. Rather than relying primarily on overwhelming combat strength, he approaches the kingdom’s problems through administration, leadership, personnel, and practical reforms. Crunchyroll’s official description specifically establishes Souma as the new king of a troubled fantasy kingdom.
That makes this the most specialized recommendation on the list for viewers who became increasingly interested in Tempest as an actual country rather than simply Rimuru’s home base.
More Management, Less Power Fantasy
Slime often rewards viewers by showing how a new road, agreement, trade relationship, or capable ally makes Tempest stronger.
Realist Hero pushes that idea much further. The protagonist’s decisions about people and resources matter more than gaining another combat skill, so the sense of progression comes from watching a kingdom function more effectively.
What to Expect Before Watching
Expect less monster evolution and less emphasis on flashy power growth. Discussions about administration, policy, economics, and political problems occupy more space.
If you enjoyed Slime despite its meetings, this may not be your best match. If you enjoyed Slime partly because of those meetings, it deserves a much higher priority.
4. Overlord
For a Much Darker Powerful Ruler
Overlord begins with Momonga remaining inside a MMORPG as it is scheduled to shut down, only to find himself in a changed situation alongside NPCs who now behave as living personalities. Crunchyroll’s official series page confirms that basic starting premise.
The strongest connection to Slime is the structure around the protagonist: an extremely powerful leader, a large group of loyal nonhuman followers, and an influence that reaches increasingly far into the surrounding fantasy world.
If You Liked the Expansion of Political Power
As Tempest grows, Rimuru’s strength stops being important only in individual battles. It affects how nations and powerful groups respond to him.
Overlord offers a similar shift from personal strength toward wider influence and large-scale power relationships. It is the best pick here if you want that ruler-centered perspective pushed further.
The Biggest Difference
The tone and moral perspective are substantially darker.
Rimuru’s leadership is strongly associated with cooperation and creating a place where different people can live together. Overlord approaches power from a much more intimidating direction, so viewers looking primarily for Slime’s friendliness and relaxed comedy may prefer TSUKIMICHI instead.
5. Farming Life in Another World
If You Wanted More Peaceful Tempest Development
Some of Slime’s most distinctive moments happen between major conflicts: new buildings appear, food and production improve, more residents arrive, and Tempest starts feeling like a real place rather than a temporary monster settlement.
Farming Life in Another World makes that kind of development the main attraction. Hiraku’s new life in the countryside grows into a larger community, and current official streaming listings continue to emphasize the expansion of his forest home into a populated settlement.
What This Anime Leaves Out
Do not choose this expecting Rimuru-style large battles or the same level of international political maneuvering.
The reward is smaller and more domestic: farming, building, food, new residents, and the gradual creation of a functioning community.
That makes it the most different recommendation here, but also the clearest choice for viewers who wished Slime spent even more time simply letting Tempest live.
Best For
Choose this if festivals, meals, construction, and everyday life in Tempest were often as enjoyable to you as the action.
If strong enemies and escalating battles are essential to your next anime, start somewhere else.
Which Anime Should You Watch First?
The easiest way to choose after Slime is to ask what you most enjoyed watching grow.
If You Want Another Tempest-Like Community
Start with TSUKIMICHI -Moonlit Fantasy-. It provides the strongest overall combination of a powerful protagonist, nonhuman allies, comedy, action, and a community expanding around the main character.
If You Want Rimuru’s Monster Progression Again
Choose So I’m a Spider, So What?. Its spider-reincarnation setup puts survival and ability growth at the center rather than moving quickly toward nation-building.
If You Want More Government and Nation Management
Go with How a Realist Hero Rebuilt the Kingdom. It removes much of the monster-power fantasy and concentrates on what happens when a protagonist actually has to make a country work.
If You Want a Darker Version of the Powerful-Ruler Idea
Pick Overlord. The protagonist-and-followers structure should feel familiar, but its treatment of power is considerably darker.
If You Mostly Miss Peaceful Life in Tempest
Try Farming Life in Another World. It takes the satisfaction of settlement growth and makes everyday community development the main event.

Conclusion
If what you want after That Time I Got Reincarnated as a Slime is another story where one unusually powerful protagonist becomes the center of a growing community, TSUKIMICHI -Moonlit Fantasy- is the strongest place to start.
But Tempest offers several different kinds of satisfaction. Choose So I’m a Spider, So What? if you want to return to monster evolution, or How a Realist Hero Rebuilt the Kingdom if Rimuru’s transition from adventurer to leader was what kept the story interesting.
Overlord is the better move toward darker political power, while Farming Life in Another World strips away most of that tension and focuses on the pleasure of watching a new community take shape. The right follow-up depends less on finding another slime and more on deciding which part of Tempest you want to build again.
