Quick Answer
Yes, if you like your isekai warm and slow-building rather than tense. It's one of the most likeable monster-in-a-new-world stories going, as long as you're not expecting real danger.
Quick Verdict
“Nation-building, not fights, is the real draw here — if watching a slime turn a cave of goblins into a functioning country sounds fun, this is an easy recommendation.”
Best for: Readers who enjoy slow-building isekai and a big found-family cast more than constant peril.
Not for: Readers who want high, sustained stakes and a short, focused story.

A jaded office worker gets stabbed on the street and wakes up in a fantasy world — as a slime. That's the setup, and it sounds like a joke, but That Time I Got Reincarnated as a Slime takes it somewhere more interesting than the punchline suggests. Rimuru, the newly slimed hero, can absorb the abilities of things he eats and talk his way into almost any alliance, and he uses those gifts not to conquer the world but to build a home for the monsters everyone else treats as vermin. Taiki Kawakami's manga adapts Fuse's hugely popular web novel, and it's become one of the defining comfort isekai of the last decade.
The thing that sets Slime apart from the pack is that the fighting isn't really the point. The real draw is construction. You watch Rimuru meet a struggling village of goblins, give them names, organize them, bring in dwarves and ogres and lizardmen, and slowly turn a patch of wilderness into a functioning country with roads, trade, and laws. It scratches the same itch as a good management game — steady, visible progress that pays off chapter after chapter.
It also just has a warm heart. Rimuru is overpowered, which usually kills tension, but the story leans into his generosity instead of his strength. He'd rather make a friend than an enemy, and the monsters he gathers around him feel like a found family rather than a list of subordinates. That tone carries a lot of weight and keeps the book pleasant to spend time in.
Kawakami's art deserves credit too. It's clean and readable, switches easily between cute slice-of-life beats and large-scale battles, and — importantly — it paces the early arcs better than the novels do, trimming some of the exposition and keeping things moving. If you tried the source material and bounced off the walls of text, the manga is the friendlier version.
The flip side of a hero this powerful is that stakes are hard to come by. Rimuru rarely feels threatened, and you seldom doubt how a confrontation will end, so the fights land more as spectacle than suspense. If you read manga for real danger, this isn't it.
The other issue is sprawl. As the nation grows, so does the cast, and the middle stretch throws a lot of factions, politics, and new names at you in a short span. It can get genuinely hard to remember who everyone is and why a particular summit matters. And the story still likes to stop and explain its own mechanics — skills, evolutions, and systems get spelled out at length, which slows the momentum right when it should be building.
Judged as what it's trying to be — a feel-good power fantasy about building something — Slime is a standout. It's generous, cozy, and more thoughtful about community than most of its rivals, and the manga is the best-paced way to read it. Go in for the world and the cast, not for white-knuckle tension, and it's an easy series to sink a long, happy afternoon into.

Another reincarnation story where growing up and building a life matters as much as the action.
Same cozy, systems-and-worldbuilding pleasure with a warm ensemble cast.
A denser take on the 'reborn into a fantasy world and start over' isekai.
