Best Isekai Anime That Never Came Back

Fans of the isekai genre, known for transporting its protagonists to alternate worlds full of fantasy and adventure, have gathered on a popular commentary forum to discuss their favorite anime that, unfortunately, were left with a single season and never got a sequel.

The isekai genre has seen a boom in recent years, with a slew of series exploring parallel worlds and characters being transported to unknown places. These stories often capture the imagination of viewers with their intriguing premises and the thrill of discovering new worlds alongside the protagonists.

However, despite the popularity of the genre, some isekai anime fail to secure a second season, leaving fans with a bittersweet taste and hope that the story will one day be picked up.

But in the midst of the disappointment, fans are reminded to never give up hope. Over the past few years, we've witnessed several cases where seemingly forgotten anime have received continuations after years of waiting. This resurgence of series almost a decade after their original broadcast has shown that, in the world of anime, you never know when a story may come back to life.

"After the shitty smartphone series got a second season, I don't think there's any anime in the world that you can say won't continue."
"Hai to Gensou no Grimgar (Grimgar: Ashes and Illusions)".
"Why Raeliana Ended Up at the Duke's Mansion".
"No Game No Life".
"Kemono Michi, an extremely funny wrestling isekai."
"Handy-man Saitou in Another World, with twelve episodes. A beautiful story despite the occasional grown-up humor."
"Seeing that the spider isekai is constantly being mentioned makes me sad. It's one of the best isekai in my opinion."
"Problem Children Are Coming from Another World, Aren't They?, a classic of classics."
"I can't think of anyone other than Hai to Gensou no Grimgar."
"Kumo desu ga, Nani ka?, it's a pity we'll never get the continuation it deserves."
"I'm a big fan of GATE, I love strategy stories."
"Death March to the Parallel World Rhapsody, probably one of my favorite light novels. I don't understand why the anime wasn't popular. Apparently there were problems between the studio and the production committee, so there was never a follow-up."
"I think Death March is one of the most underrated new isekai. I think we were at a time when people were starting to make fun of isekai who didn't do anything new, and what we got was pretty conventional. But I still loved the execution, even if it wasn't unique."
"Uncle from Another World. Extremely good comedy, but I doubt it will continue."
"Cautious Hero, perhaps."
"Hachi-nan tte, Sore wa Nai deshou!, a great isekai that ended in a totally closed way."
"Knights and Magic definitely deserves a second season, especially since it ended on something of a cliffhanger. Nonetheless, I don't think there's a big enough fan base left to inspire a sequel."
"Knights and Magic was amazing, I loved the addition of the mechs and not just broken abilities/magic in the mix, plus it's hard not to love Ernesti's genuine love for his hobby."
"Wise Man's Grandchild, probably. I'd like to see the continuation of that series."
"Since no one has the balls to mention it, I will. I'm still hopeful that Redo of Healer will continue, although what follows isn't really good compared to the beginning."
"Vision of Escaflowne".
"Why hasn't anyone mentioned Drifters?"
"Isekai Meikyuu de Harem wo (Harem in the Labyrinth of Another World), but the industry was afraid and gave a closed ending to the only season."
