What Anime Is Most Like That Time I Got Reincarnated as a Slime?

The anime most like That Time I Got Reincarnated as a Slime is Overlord, because it shares the core fantasy: a reincarnated protagonist who is wildly overpowered, surrounded by loyal non-human followers, and slowly turning a base into a powerful realm. For a non-human lead specifically, Reincarnated as a Sword is the closest match.

The difference comes down to tone. Slime‘s Rimuru Tempest builds his nation through diplomacy and genuine warmth, while Overlord‘s Ainz Ooal Gown rules through fear and overwhelming dread. Both deliver the power-fantasy comfort of watching a protagonist who is never truly threatened, but they aim that fantasy at very different feelings.

Why Does Slime Feel Different From Other Isekai?

That Time I Got Reincarnated as a Slime, adapted by studio Eight Bit from Fuse’s web novel, stands out in a crowded isekai field because it combines three appeals that rarely share one show. Most isekai pick one and run with it; Slime layers all three.

  • A non-human protagonist — Rimuru starts as an actual slime, not a sword-swinging human hero, which reshapes how every encounter plays out.
  • Nation-building over questing — the real plot is growing the Jura Tempest Federation, recruiting monsters, and managing alliances, not grinding dungeons.
  • An OP main character with stakes that are political, not physical — Rimuru can win almost any fight, so the tension shifts to diplomacy, war between nations, and protecting his people.

That mix is why “anime like That Time I Got Reincarnated as a Slime” is such a specific search — fans aren’t just asking for any isekai, they want that exact recipe of overpowered comfort plus community-building. The picks below are sorted by how closely they hit it.

12 Anime Like That Time I Got Reincarnated as a Slime, Ranked

Here are twelve series ranked by how well they recreate the Slime experience, with the standout reason to watch each.

  1. Overlord — The closest overall match. Ainz Ooal Gown is trapped in his MMO body as a skeletal overlord and slowly expands the Sorcerer Kingdom with an army of devoted non-human guardians. Same OP-lead-plus-nation-building DNA, darker tone.
  2. Reincarnated as a Sword — A man dies and is reborn as a sentient magic sword, bonding with a cat-girl adventurer named Fran. The non-human reincarnation angle and steady power growth feel pulled straight from Slime‘s playbook.
  3. How a Realist Hero Rebuilt the Kingdom — Kazuya Souma is summoned and immediately put in charge of a struggling kingdom, which he fixes with economics and policy rather than swords. The purest nation-management pick on this list.
  4. The Rising of the Shield Hero — Naofumi Iwatani rebuilds his reputation and his own party from the ground up after being betrayed. Less monster-village, more redemption arc, but the “build a faction that’s loyal to you” core matches.
  5. By the Grace of the Gods — Ryoma Takebayashi reincarnates and quietly tames slimes, runs a business, and helps a frontier community. The slow-life warmth and monster-companion angle make it a gentle cousin to Slime.
  6. Ascendance of a Bookworm — Myne is reborn in a world with almost no books and sets out to build a printing industry. It’s nation-building of a different kind — institutional and cultural — with the same satisfying “watch a society improve” payoff.
  7. The Saga of Tanya the Evil — Tanya is reincarnated as a child soldier-mage in a wartime empire. The overpowered reincarnated lead is here in full, with a sharper, militaristic edge and a genuinely ruthless protagonist.
  8. Mushoku Tensei: Jobless Reincarnation — Rudeus Greyrat lives a full second life from infancy, mastering magic as he grows. Deeper character drama than Slime, but it shares the from-scratch growth and rich fantasy world-building.
  9. The Faraway Paladin — William is raised by undead guardians and grows into a paladin shaping a frontier town. Strong found-family and community-building threads with a thoughtful, warm tone.
  10. In the Land of Leadale — Cayna wakes inside the MMO she played, now centuries later, and navigates a world her old choices helped shape. Comfortable, low-stakes, and full of reunion and rebuilding beats.
  11. Banished from the Hero’s Party — A relaxed slow-life isekai about an overpowered character who chooses a quiet frontier life. The cozy, settle-down energy echoes Slime‘s quieter village chapters.
  12. The Wrong Way to Use Healing Magic — Usato is summoned and trained into a brutally strong healer-bruiser. A fun OP-lead pick for when you want the power fantasy without the heavier politics.

Honorable mentions: KonoSuba (for comedy-leaning isekai fans), Wise Man’s Grandchild, and Cautious Hero all sit nearby but lean further from the nation-building core.

Which Pick Should You Watch First?

If you finished That Time I Got Reincarnated as a Slime and want the most seamless next step, start with Overlord — it gives you the same overpowered lead and base-expanding structure, just with a colder, more menacing ruler in Ainz Ooal Gown. If what you loved most was Rimuru Tempest not being human, jump to Reincarnated as a Sword instead.

Craving the management and politics over the action? How a Realist Hero Rebuilt the Kingdom is your pick, with Ascendance of a Bookworm close behind for a slower, smarter build. And if you mostly want the warm, low-stress slow-life vibe of Rimuru’s village, By the Grace of the Gods delivers comfort viewing with familiar slime companions.
