Approximately 85.6% of light novels toanime adaptations are isekai, so they can start to blend together due to the sheer volume of material out there.Overlordhas an ingenious twist that permits it to stand out from the crowd: the reincarnated protagonist is reborn as an evil character. This is a power fantasy where the “heroes” are utterly outmatched and play little more than supporting roles.
Overlordfollows Ainz Ooal Gown, the titular villain, as he slowly establishes The Great Tomb of Nazarick as a dominant force in a fantasy world that cannot hope to measure up to his broken abilities. The anime is dark, funny, and frequently epic.

A light novel and anime classic,The Melancholy of Haruhi Suzumiyafollows Kyon as he is pressured into joining the SOS Brigade by Haruhi, a strong-willed girl who is far more important than she initially appears. Kyoto Animation’s show incorporates comedy, character growth, and philosophical musings quite well, crafting an experience that has gone on to influence many other shows.
The Disappearance of Haruhi Suzumiyais the anime’s crowning achievement as it is one ofthe best movie sequels of all time. The show is also pretty good, although its second season tends to be rather polarizing.

The show was at its best during the ’90s, with 1995’sSlayersdelivering a near-perfect mix of parody, action, and world-building.

Slayersboasts an incredible cast of characters, particularly its leads in the formidable Lina Inverse and the likable Gourry Gabriev. These two rank among anime’s most endearing double acts, and their charm has not declined at all over the last few decades.

Ever sinceSword Art Online’s massive explosion in popularity, anime has been bleeding the isekai well dry, often using light novels as launching pads. There have beenquite a few memorable showssinceSAOchanged the game, butKonoSubastands above most of its contemporaries due to its willingness to poke fun at the genre’s tropes and cliches.

Based on Isuna Hasekura’s light novel,Spice and Wolffollows the travels of Kraft Lawrence, a merchant with aspirations of opening a store, and Holo, a wolf goddess who has been around for a few hundred years. Together, they travel across a Medieval Europe-esque world towards Holo’s homeland, growing closer to each other along the way.
Spice and Wolfis a quiet series centering predominantly around the trade business, at least that serves as the driving force behind most of the arcs covered by the anime. The show’s true selling point is the relationship between Lawrence and Holo, which is nothing short of incredible.

Baccano!is overwhelming, too ambitious for its own good, and difficult to follow at the best of times. It is also nail-bitingly suspenseful, gloriously animated, and endlessly rewatchable. Split into three timelines,Baccano!juggles a massive roster of characters who are all big personalities; incredibly, the anime manages to make each of these figures stand out in their own right.
The anime only scratches the surface of what is in Ryogo Narita’s light novel series, but it serves as a great introduction to this world.

Published by Type-Moon and set in an alternate reality to theFatefranchise, Kinoko Nasu’sThe Garden of Sinnersfollows a detective agency that specializes in supernatural cases. However, this description does not begin to reflect the light novel and anime’s depth, complexity, and creativity.

In an eternal river of isekai stories,Re:Zeroraises above the waves in a haunting fashion. Subaru randomly finds himself teleported to a fantasy world, and he quickly embraces the opportunity to be a hero. Armed with the ability to reset time following his death, Subaru becomes enamored with Emilia, a half-elf, and picks up something of a harem.
All of this sounds like the typical isekai, however,Re:Zeronever makes anything simple for Subaru. This show is not a power fantasy, rather a character study revolving around people suffering from deep identity and psychological issues. The anime adaptation is faithful to the light novel and of very high quality.
