Overview

This manga adaptation of That Time I Got Reincarnated as a Slime is one of the signature isekai works to arrive in the 2010s, and it serves as a welcoming entry point into a much larger franchise. Its hook, a protagonist reborn as the weakest monster type yet equipped with abilities that bend the rules around him, gives the story a playful engine that keeps its humor intact even as the stakes grow.

What distinguishes this version within the wider series is its balance. The manga shifts comfortably between comedy, adventure, and the patient work of building a community, letting politics, kingdom management, and war enter the frame without losing its light touch. Readers who enjoy watching a small premise expand into something structural have 168 chapters across 23 volumes to follow, and the finished run means the arc reaches a settled stopping point rather than trailing off.

Approachability is a genuine strength. The content level stays mild, the tone stays buoyant, and the surrounding cast of monsters, dragons, and demons reads as inviting rather than intimidating. It suits newcomers to isekai as well as longtime fans who want a visually driven take on the material, and digital availability through Tapas makes it simple to sample before committing.

Synopsis

This manga tells the story of Mikami Satoru, an ordinary thirty-seven-year-old man whose life ends when a random attacker stabs him in the street. He wakes in another world, unable to see or hear, and gradually realizes that he has been reborn as a slime, a monster widely dismissed as the weakest of all creatures. Rather than despair, he settles into an easygoing existence in a cave, where his unusual circumstances begin to shape a new identity.

His solitary life changes when he meets Veldora, a storm dragon of calamitous reputation sealed within the cavern. The two become friends, and Veldora gives him the name Rimuru. Rimuru also possesses two unique skills, Predator, which lets him consume and absorb the abilities of what he devours, and Great Sage, which grants him vast knowledge of the world's rules. With these gifts, he starts to explore the surface and quickly becomes entangled in a struggle between goblins and a fanged wolf clan.

Those early encounters draw Rimuru into a growing role as a leader of monsters, a position he never sought. He gathers allies from many species, works to secure food and shelter for them, and must navigate the suspicions of human settlements and the ambitions of powerful neighboring figures, including demon lords and rival nations. The central conflict follows Rimuru as he tries to protect the community he is building, balancing diplomacy, politics, and war while deciding what kind of ruler a former slime can become.

Should You Read It?

Read it if you enjoy

  • Pick this up if you want an approachable isekai manga about a reincarnated slime who builds a monster community from a small cave encounter.
  • Read if you enjoy a balance of comedy, adventure, and patient kingdom-management politics within a mild-content fantasy.
  • Try it as a visually driven entry point to the wider Slime franchise, since it adapts the light novel storyline across 23 volumes.
  • Consider it if a finished 168-chapter run and a settled stopping point appeal more than an ongoing serialization.

It may not suit you if

  • May not suit readers who prefer the original light novel prose, as this entry is a manga adaptation rather than the franchise's origin point.
  • Those who dislike isekai or reincarnation hooks, or monster-led politics, may find the premise and kingdom-building focus less engaging.
  • Readers wanting a short, single-sitting story might be deterred by 168 chapters across 23 volumes.

Why It Connects With Audiences

Why people love it

Production Background

Fuse created That Time I Got Reincarnated as a Slime, and the work began as a light novel released under Micro Magazine's GC Novels label, where the official series page credits Fuse and Mitz Vah alongside the publisher. This individual entry covers the manga adaptation built from that light novel source material. The record dates the entry to 2014, marks it as finished, and tallies 168 chapters collected across 23 volumes.

English-language publication of the source light novel is handled by Yen Press, which catalogs it within its novel line. Chinese-language editions are listed by Kadokawa Taiwan. The record also names Tapas among the platforms where the work is available.

As a reading-format release, this entry carries no episode count and no runtime, so chapter and volume totals serve as the measure of its length. Its descriptive tags place it in isekai and reincarnation territory alongside kingdom management, politics, medieval warfare, and demons, and the record identifies it as the main manga installment adapted from the light novel original.

Franchise Context

This entry is the main manga adaptation of That Time I Got Reincarnated as a Slime, a light novel series published under Micro Magazine's GC Novels label. It is a comic retelling rather than an original work, converting the prose story into sequential art across 23 collected volumes and 168 chapters. Readers arriving through this version are meeting an adaptation of the source novels, not the origin point of the franchise itself.

The property has grown into a multi-format franchise, so the manga takes its place beside the original light novels, the anime adaptation, and various spin-offs and side stories that approach the same world from different angles. Each version retells or extends the premise of a reincarnated slime who builds a monster nation, which means this manga works as one accessible entry into a much larger shared continuity.

For newcomers, the manga serves as a companion to the novels, following the same broad storyline while compressing and visualizing it. Additional arcs and spin-off titles carry the franchise past what these volumes cover, so this series is a starting point within the wider property rather than its conclusion.

Franchise Path

  1. Franchise path: begin with the original light novels, then read this main manga adaptation.
  2. Continue in the same franchise with the anime adaptation and official spin-off or side-story entries for the wider continuity.

After You Finish

Continue with

  • This manga reaches a settled stopping point at 23 volumes, but the franchise continues in the light novels and anime adaptation.
  • Move to those continuing versions for later arcs and additional material in the same shared world.
