  • Episodes: 50+ (ongoing)
  • Genre: Fantasy, Psychological, Thriller
  • Where to Watch: Crunchyroll
  • Why Watch: Subaru’s power is dying and returning to checkpoints—and the show makes him earn every victory through trauma. Dark, psychological, and emotionally brutal, Re:Zero deconstructs isekai tropes while telling a gripping story. Suffering has never been so compelling.

3. That Time I Got Reincarnated as a Slime

  • Episodes: 72+ (ongoing)
  • Genre: Fantasy, Action, Comedy
  • Where to Watch: Crunchyroll
  • Why Watch: Starting as the weakest monster and becoming one of the strongest beings makes for incredible power fantasy. But the real hook is the nation-building—watching Rimuru create a monster civilization is uniquely satisfying. Lighter tone with surprising depth.

4. Overlord

  • Episodes: 52 (Season 5 coming)
  • Genre: Fantasy, Action, Dark
  • Where to Watch: Crunchyroll
  • Why Watch: What if you got isekai’d as the final boss? Ainz is an undead overlord with an army of monsters, and the fun is watching him strategize world conquest while accidentally being worshipped. Dark comedy meets power fantasy in the best way.

5. The Rising of the Shield Hero

  • Episodes: 50+ (ongoing)
  • Genre: Fantasy, Action, Drama
  • Where to Watch: Crunchyroll
  • Why Watch: Naofumi is summoned as a hero, immediately betrayed, and has to build himself up from nothing. The underdog revenge fantasy of season 1 is incredibly satisfying. Watching him prove everyone wrong never gets old.

6. Konosuba: God’s Blessing on This Wonderful World!

  • Episodes: 32+ (ongoing + movie)
  • Genre: Comedy, Fantasy, Adventure
  • Where to Watch: Crunchyroll
  • Why Watch: The ultimate isekai parody. Kazuma gets stuck with useless goddess Aqua, explosion-obsessed Megumin, and masochist crusader Darkness. It’s hilarious from start to finish, skewering every isekai trope while being genuinely loveable.

7. The Eminence in Shadow

  • Episodes: 32+ (ongoing)
  • Genre: Action, Comedy, Fantasy
  • Where to Watch: Crunchyroll
  • Why Watch: Cid wants to be an overpowered shadow mastermind—and accidentally becomes one for real. Parody that’s also genuinely awesome, with incredible fight scenes and hilarious situations. Best of both worlds.

8. Sword Art Online

  • Episodes: 96+ (ongoing)
  • Genre: Action, Adventure, Romance
  • Where to Watch: Crunchyroll / Netflix / Hulu
  • Why Watch: The series that launched the modern isekai explosion. Trapped in a death game where dying means dying for real. Despite criticism, SAO remains influential and entertaining, with genuinely great arcs. The Progressive movies are especially excellent.

9. The Beginning After the End

  • Episodes: 24+ (ongoing)
  • Genre: Fantasy, Action, Drama
  • Where to Watch: Crunchyroll
  • Why Watch: A king reincarnates into a magical world, retaining his experience and wisdom. The power progression is satisfying, and Arthur’s journey through this new life offers both action and emotional depth. Perfect for Solo Leveling fans.

10. No Game No Life

  • Episodes: 12 + Movie (Season 2 hopeful)
  • Genre: Fantasy, Comedy, Ecchi
  • Where to Watch: Crunchyroll
  • Why Watch: Gaming siblings get transported to a world where everything is decided by games. The mind games are brilliant, the visuals are gorgeously colorful, and watching Sora and Shiro outplay everyone is endlessly satisfying. We’re still waiting for Season 2.

11. Log Horizon

  • Episodes: 62 (Complete)
  • Genre: Fantasy, Action, Adventure
  • Where to Watch: Crunchyroll
  • Why Watch: Unlike most isekai, Log Horizon focuses on society-building and economics in a game world. How do you rebuild civilization when you’re trapped in an MMO? Smart, strategic, and refreshingly different from typical power fantasy isekai.

12. Grimgar of Fantasy and Ash

  • Episodes: 12 (Complete)
  • Genre: Fantasy, Drama, Adventure
  • Where to Watch: Crunchyroll
  • Why Watch: What if isekai was actually hard? Grimgar follows weak adventurers struggling to survive against basic goblins. It’s slow, melancholic, and beautiful—the anti-power fantasy that shows what being transported to another world might actually feel like.

13. Ascendance of a Bookworm

  • Episodes: 36+ (ongoing)
  • Genre: Fantasy, Slice of Life, Drama
  • Where to Watch: Crunchyroll
  • Why Watch: A book-obsessed librarian reincarnates in a medieval world without printing. Her goal? Make books exist. It’s surprisingly compelling—watching Myne slowly introduce technology and climb social ladders is addictive. Cozy yet engaging isekai.

14. So I’m a Spider, So What?

  • Episodes: 24 (Complete)
  • Genre: Fantasy, Action, Comedy
  • Where to Watch: Crunchyroll
  • Why Watch: Reincarnated as the weakest monster in a dungeon, our protagonist survives through cunning and comedy. The spider POV sections are hilarious, and watching her evolve is satisfying. Underrated gem that deserved more attention.
