Best Isekai Anime Like That Time I Got Reincarnated As A Slime

That Time I Got Reincarnated as a Slime is unquestionably one of the most successful isekai anime of all time. Based on a popular light novel by Fuse, the adaptation is currently in its third season, which has been confirmed for 24 episodes, bringing the show’s total to 72. That does not take into account The Slime Diaries, a 2021 slice-of-life spin-off that is canon albeit inconsequential. Tempest’s journey to establish a country for monsters that can co-exist with humans has captured the cultural zeitgeist, with the anime earning praise for its strong animation, lovable characters, and generally positive tone.

Isekai anime are a dime-a-dozen, and That Time I Got Reincarnated as a Slime shares quite a few things in common with many of the genre’s “generic” releases. Despite that, very few series manage to scratch the same itch as 8bit’s adaptation, and most cannot be promoted beyond a basic “well, they are both isekai with somewhat overpowered MCs.” Fortunately, exceptions exist. Here are a couple of anime like Tensei shitara Slime Datta Ken.

5 Re:Monster

Goblin King

Airing alongside That Time I Got Reincarnated as a Slime season 3, Re:Monster‘s similarities to Fuse’s story are hard to miss. Both anime involve protagonists who are brutally murdered and reincarnate as low-level fodder monsters in fantasy worlds: Rimuru awakens as a Slime and Re:Monster‘s Rou revives as a goblin. Both MCs learn abilities through absorption, with Rou gaining skills by eating monsters. This mechanic allows them to grow rapidly and eventually set themselves up as leaders, with Rou taking over his goblin clan without breaking much of a sweat. Both protagonists are also willing to kill if the need arises.

Due to the show still being in its early days, this recommendation comes with the caveat that Re:Monster is still a work in progress that might lose momentum as it progresses. Despite overlapping quite extensively with Reincarnated as a Slime, Studio Deen’s anime feels quite different, mainly due to having a comparatively meaner tone. Re:Monster is very much a dark fantasy.

4 Farming Life In Another World

A Safe Haven

While not devoid of action or drama, That Time I Got Reincarnated as a Slime is relatively carefree, delivering a comforting escape from reality about a Slime monarch who wants to provide a home for mistreated species.

Minus the “transforming into a monster” element, 2023’s Farming Life in Another World has generally the same core appeal as Reincarnated as a Slime. After working himself to an early grave, Hiraku is granted the opportunity to pick his next life, and he decides to become a farmer. Reincarnating in a dangerous forest in a magical world, Hiraku builds a homestead that quickly attracts the attention of monsters in the area.

Before long, the protagonist is living alongside a vampire, an angel, an oni, etc. in a town he founded. Leaning into slow-life territory and incorporating a fairly large harem, Farming Life in Another World focuses on the town’s expansion and its attempts to create connections with nearby cities.

3 Tsukimichi: Moonlit Fantasy

An OP Isekai Protagonist Who Creates A Realm For Demi-Humans

Tsukimichi: Moonlit Fantasy is a consistently entertaining b-tier isekai anime. While perhaps not on the same level as the genre’s most beloved properties, it will likely hit the mark with people who enjoy those shows. Makoto is summoned by a goddess to serve as a hero in her world; however, after she takes a look at her candidate, she decides he is too ugly and punishes him. Fortunately, Makoto gets a helpful boost from another god, allowing him to not only survive but thrive in his new home.

Tsukimichi: Moonlit Fantasy offers a fun twist on the isekai anime formula, and these other shows can scratch the same itch.

Blending humor, adventure, and some harem elements, Tsukimichi has a strong roster of characters, most of whom are allowed to flourish and build relationships with other characters besides Makoto. The protagonist eventually sets up a special realm and starts to populate it with Demi-Humans, creating a regime that is generally welcoming.

2 Overlord

(Accidentally) Conquering The World Through Fear

Probably the most obvious anime like That Time I Got Reincarnated as a Slime, Overlord is essentially the “evil” alternative, in that the protagonist gradually leans into his villainous persona. Deciding to stay online as his favorite MMORPG ends, the protagonist suddenly finds himself stuck as his character, Ainz Ooal Gown, and unable to log out.

Assisted by his guild’s AI subordinates, Ainz has to make the best of a strange situation, which involves setting up The Great Tomb of Nazarick and slowly spreading its reach over a world that is not prepared to deal with a cosmic-level threat. Unlike Rimuru, Ainz does not have much desire to play nice with humans, even if he prefers to take on a reactionary rather aggressive role.

1 So I’m a Spider, So What?

Weirder Than A Slime?

Reincarnating as a slime or goblin might seem like terrible luck, but you know what is worse? Waking up in the body of a little spider. Compared to her classmates who were isekai’d into the same world, Kumoko drew the shortest straw, finding herself cast as a baby of a species not known to last long. Forced to adapt quickly to survive, Kumoko must come to grips with this universe’s gaming-style mechanics if she wants to grow stronger; in the meantime, she develops friendships with other spiders and monsters.

Out of all the recommended shows, So I’m a Spider, So What? comes the closest to matching That Time I Got Reincarnated as a Slime‘s tone. Both shows blend action and humor well, and they dedicate plenty of time to chronicling their protagonists’ power growth. While nowhere near as powerful as Rimuru, Kumoko is still very capable in a fight, all the while being incredibly charming.
