Isekai Anime with incredible sense of scale

• Mushoku Tensei and That Time I Got Reincarnated As A Slime show grand scale through world-changing conflicts and rise to power.

Some anime shows stand out from all others because of their sheer size. This has nothing to do with the number of episodes, but how sprawling the stories feel. One of the best examples of this is One Piece, which, in addition to an astonishing number of episodes, has a huge cast and an even bigger world where the fate of the main character has affected everything.

There are shows that do this in almost every genre, and isekai is no exception. Isekai lends itself well to this premise, as the very idea of ​​being in another world introduces the potential for very high stakes in an expansive, detailed environment.

4 Mushoku Tensei: Jobless Reincarnation

Rudeus is involved in world-changing conflicts

Mushoku Tensei is one of the most popular isekai currently airing, and part of its appeal is its great sense of scale. Viewers follow Rudeus literally from the day he was born in the New World.

2 Tsukimichi: Moonlit Fantasy

Makoto's lonely adventure expands wonderfully

Tsukimichi is also an isekai with some of the usual tropes everyone is used to by now. The main character is transported to another world, imbued with a useless power, but can somehow be overwhelmed, and all the ladies fawn over him.

However, Makoto is a much more likable main character than most. As he begins to build an empire where outcasts like himself can live in peace, the second season arrives and raises the stakes. It introduces other heroes from Makoto's world and more empires, kingdoms and races, all slowly coming to terms with the growing influence of Makoto and his empire.

1 The 12 Kingdoms

Youko's rise from Normie to Queen is epic

The 12 Kingdoms uses its simple isekai premise to create an intricately detailed world. When Youko Nakajima is whisked away from her everyday life to become the queen of a kingdom in another world, she feels out of her element.

Youko's path to becoming queen is not an easy one, and she is soon embroiled in a conflict involving the most powerful forces in the land she is supposed to rule with some intrigue from the other kingdoms. However, the story does not focus entirely on Youko. Viewers get to see the world through the eyes of other individuals, some in completely different empires located in the same world. This goes a long way towards creating a grand sense of scale for the series. The series is fondly remembered as one of the most well put together isekai shows of the generation.
