Should I read Slime manga or LN?
If you have discovered That Time I Got Reincarnated as a Slime, also called Tensei Shitara Slime Datta Ken, you might already know how addictive this series can be. With Rimuru’s journey from a simple slime to one of the most powerful beings in his world, the story has captured millions of fans across anime, manga, and light novel formats. But if you are just getting started, you might be wondering: should you read the manga or the light novel first?
This is a common question because both versions tell the same story but in slightly different ways. Let’s break it down together so you can decide which one works best for you.

What is the Slime Light Novel?
The light novel is the original version of the story written by Fuse. It began as a web novel and was later published officially as a light novel series. Currently, it has more than 20 volumes released and is still ongoing.
Reading the light novel gives you the complete and most detailed version of Rimuru’s adventure. It explores not only the battles and politics but also Rimuru’s inner thoughts, strategies, and emotions. The writing dives deep into world-building, giving you a clearer view of how nations are structured, how magic systems function, and how alliances are formed.
If you enjoy long, descriptive storytelling where every detail matters, then the light novel is the best starting point.
What is the Slime Manga?
The manga, illustrated by Taiki Kawakami, adapts Fuse’s light novel into a visual format. It captures the key events of the story but presents them in a more concise and action-packed way. Instead of long explanations, you get to see Rimuru’s battles, transformations, and interactions directly on the page with expressive artwork.
The manga is easier to follow if you prefer fast pacing and enjoy art-driven storytelling. It does cut some details from the light novel, but it makes up for it by giving fans striking illustrations of their favorite characters and epic fight scenes.
Differences Between the Manga and the Light Novel
So which one should you choose? Here are the main differences:
- Detail and Depth – The light novel includes far more information about politics, magic systems, and character motivations. The manga condenses this into shorter scenes.
- Pacing – The manga moves faster and focuses on major events, while the light novel often spends more time explaining background and strategy.
- Visual Appeal – The manga offers artwork that brings Rimuru and Tempest to life, while the light novel relies on text with occasional illustrations.
- Canon Material – The light novel is the main source material, so it is always ahead in the story compared to the manga and the anime.
Which One Should You Read First?
If you are someone who wants the full, uncut experience with every detail of Rimuru’s rise to power, the light novel is the way to go. It will take more time and patience, but you will appreciate the extra depth in character development and world-building.
If you are new to the series or prefer a more visual approach, then starting with the manga might be better. It is easier to digest and allows you to enjoy the story without getting overwhelmed by long paragraphs of exposition.
Some fans even recommend reading both. You can enjoy the manga for its art and action while using the light novel to fill in the details that the manga skips. This combination gives you the best of both worlds.
The Anime Connection
Another factor to consider is the anime adaptation. If you have already watched the anime, you might wonder whether to continue with the manga or jump straight into the light novel. Since the anime follows the manga’s pacing more closely, you might find the light novel refreshing because it goes beyond what the anime covers.
In fact, if you are eager to know what happens next before future anime seasons are released, the light novel is the fastest way to stay ahead of the story.

Which Version Do Most Fans Prefer?
Interestingly, fans are quite divided. Many readers enjoy the manga because it is easier to collect and follow visually. Others swear by the light novel because it provides the “true” version of events.
Ultimately, it comes down to your reading style:
- If you love illustrations and faster storytelling, pick the manga.
- If you prefer depth, background lore, and a more immersive world, pick the light novel.
- If you cannot decide, try both. Start with the manga for fun and switch to the light novel when you crave more detail.
So should you read That Time I Got Reincarnated as a Slime in manga or light novel form? The answer depends on your preferences. Both formats tell the same exciting story of Rimuru’s transformation from a humble slime into a legendary figure, but they do it in different styles.
The light novel gives you the full experience with in-depth storytelling, while the manga offers a quicker, visually engaging adventure. There is no wrong choice, and many fans enjoy switching between both to get the complete picture.
At the end of the day, what matters most is diving into Rimuru’s world and experiencing the magic of Slime Datta Ken in the format that feels right for you. Whether you read the manga, the light novel, or both, you are in for one of the most entertaining journeys in the isekai genre.
