From the cold and quiet reaches of space to fantasy metropolises in which species of every variety rub shoulders and negotiate deals, anime takes place in all kinds of places: many of these worlds are nothing more than cardboard cutouts: they may have the perfect appearance, but there's no depth beneath the surface.
World building is the process of constructing a setting and fleshing it out in all the necessary detail that it must have to be convincing. Economics, geography, fauna, and politics are just a few of the most essential considerations in isekai anime. The show must successfully contrast the new world with the old. Here are some isekai who have created phenomenal worlds.
History is a much-deeper, more complicated, and more complicated subject than most people credit for, and it's only when history enthusiasts begin to enlist the help of names, dates, and incidents that the whole picture begins to emerge. That's why most anime shy away from including real people into their world-building: it's simply too complicated. Drifters tackles this challenge head on.
This underrated isekai anime shows many of history's most fascinating figures thrown together and then forced to fight one another. Drifters is a great anime, but it's the depth of its world building that's the real attraction.
7 Ascendance Of A Bookworm
World building can be vast, and in some cases, it must be, since it's a whole world that's being worked on, after all, but it's okay if the process starts small. One of the best world building techniques is to pick a single element of the world, flesh it out until it's fully plausible, and use it as the foundation for everything else.
The minor thing is reading in Ascendance of a Bookworm. The protagonist is a little girl beginning the long journey towards literacy, and while conquering a book may not be as difficult as other isekai protagonists do, it provides the framework for some truly inventive world building.
6 Sword Art Online
Sword Art Online's achievements are easy to downplay. The series seemed to fit into every corner of geek culture, and overexposure irritated some people. However, dismissing the series based on its popularity alone would be a mistake.
The isekai game has some of the best world building, and part of what makes it so great is its willingness to go above and beyond its fictional MMO boundaries. The sinister corporation and mysterious figures pulling the strings back on earth receive ample time and attention, allowing the writers to develop the politics, military activities, and logistics of two worlds at the same time.
5 Now And Then, Here And There
When it comes to the greatest isekai, Here and There, it isn't one of the first anime that most people refer to, but it should be when it comes to its world building. The desert world into which Shuu is thrown as the result of his misguided attempt to rescue a strange girl is spectacular.
When the world in which they occur feels like every other, and that of Now and Then, Here and There, Isekai's world doesn't. A vast fantasy that boils under the light of a red giant, this anime's world is a detailed dystopia that meticulously investigates every horrible consequence of the climate crisis and military supremacy it depicts. Its world is harrowing to see, but brilliantly constructed.
4 The Twelve Kingdoms
The Twelve Kingdoms is by far one of the best isekai when it comes to world building, and part of the reason is that it acts as if it's a dozen worlds that must be constructed. Each of the 12 kingdoms has a unique government and culture that sets them apart from the others.
Even anime that succeed in world building fail to make their worlds feel like real estate: they're clever fantasy concepts rather than much more. Each of the twelve kingdoms feels like a place that actual people might inhabit, going about their daily lives, and that's no small achievement. The Twelve Kingdoms is just long enough to do what it needs to do.
3 Grimgar: Ashes And Illusions
The protagonists in Grimgar: Ashes and Illusions aren't about war, they're more about battles. The difference may seem small, but it matters when it comes to world building. The protagonists here aren't the finest wizards in their world, fighting other wizards for a shiny title. They're soldiers, tired, confused, and basically mediocre people who are striving to survive difficult situations.
Grimgar is relatively short, telling what it has to say before reciting it there. Regardless of whether one likes anime that may be binged in a day or ones that last hundreds of episodes, Grimgar can't help but attract admirers for its warm-heartedness.
2 Log Horizon
World building can be seen in many ways, but regardless of the narrative or genre, one of its most essential aspects is coherency. Every item must work together to form a cohesive unit. It all must make sense together.
Log Horizon is an isekai anime about MMORPG characters that makes it stand out from many other shows, but does not immediately set it apart from other shows. Instead, Log Horizon makes its MMO premise one of its biggest strengths. One would need several days and a couple of flowcharts to explain how Log Horizon achieves its goals in terms of isekai world building.
Before Log Horizon, Sword Art Online, and a hundred imitators, there was.hack//Sign. An anime's method of lore reveals a lot about its aptitude for world building..hack//Sign does more to realize a vast, interlocking, cohesive system of lore than most anime can dream of.
Tsukasa, the leader of the World, and his many other little details help build up a world that feels as though one might easily enter it through its excellent video game adaptations.
