The isekai genre is incredibly popular for its ability to create compelling stories with ever-changing characters and settings.
These include those where the protagonist is a king or of royal lineage. And if we think about it this can give rise to many situations, with strong and solemn or even dethroned characters who must regain power.
But let’s stop wasting time on small talk and see which are the best isekai anime with a king or royal character.
This list is made based on our personal opinion and taste.

10. Tsukimichi – Moonlit Fantasy

Tsukimichi is a 2021 isekai anime based on a 12-episode light novel.
Makoto Misumi suddenly finds himself in a new world, summoned by a goddess, who reveals to him that his parents have made a pact to make him the hero of that world.
He is ready for the task, only to be suddenly betrayed by the god, who says he doesn’t consider him aesthetically handsome enough for the task.
So, Makoto will end up an outcast in a world he does not know, but that is until he develops very strong powers thanks to the help of another god.
This is how his revenge begins, and we’ll see him gain more and more power until he finally becomes a king.
Tsukimichi is a simple and certainly not jaw-dropping isekai, suitable for those who want to see an anime without too much effort.
Its plot, soundtrack, and animations, as well as the characters, are barely mediocre.

I’m the Villainess, So I’m Taming the Final Boss is an isekai with a plot so uncreative that it is identical to that of Hamefura, another anime named in this list and released earlier.

Souma finds himself in a difficult position. The country is indeed at war with neighboring states and the whole situation is everything but easy.
Plus he is in a difficult relationship with the former ruler’s daughter, who apparently hates him for no particular reason.
How a Realist Hero Rebuilt the Kingdom is a light-hearted, humorous, and noncommittal isekai, focused on war and politics. Sometimes you will also notice there is a not-so-bad romance subplot.

The Magical Revolution of the Reincarnated Princess and the Genius Young Lady is a unique isekai anime released in 2023, with an ongoing animated adaptation based on the light novel of the same name.

And to realize his new idea, which is to conquer Japan, he must first become a full-fledged employee and settle into society.
An easygoing anime, almost a parody of the isekai genre. Making the demon king Satan himself an awkward, job-seeking individual like any teenager is undoubtedly a bold move.

2. Overlord

Overlord is an show based on another light novel series written by Kugane Maruyama and illustrated by So-Bin in 2012 that we also consider as one of the best isekai anime with experience levels.
A nice Isekai classic, it takes the basics of the genre and reworks them into a dark fantasy atmosphere all its own.
Although the initial premise is the same as much other anime in the genre, here the protagonist Momonga is not reincarnated into a weakling, but rather into what is considered the most powerful being in his world. And that’s how he claims the title of Sorcerer King of the Sorcerer Kingdom.
This will lead him to be in command of a powerless army with which he will slowly conquer everything conquerable, in a series of events that are never predictable or trivial.
The great virtue of Overlord is the rawness of the actions performed by Momonga and the real and tangible weight they have on the people of the world. And that’s exactly why we consider this show as one of the best isekai anime with an anti-hero MC.
Indeed, we aren’t dealing with the classic weak and generous Isekai protagonist but a true anti-hero.
1. That Time I Got Reincarnated as a Slime

One of the most popular isekai and fantasy anime of recent times, animated in various series by Studio 8-Bit and based on Fuse’s light novel of the same name.
Like much of isekai, here too we find a character who after his death is transported to a fantasy world. In this case, the protagonist is Satoru Mikami, a salaryman who dies stabbed after saving a colleague from a robber.
The special feature lies in the fact that he will be reincarnated as a blind slime. After befriending the dragon Veldra, he begins his adventure in the world, gathering around him a vast array of followers.
This is one of the best isekai anime with a non-human MC and this brings some freshness into the overall story.
Don’t be fooled by his appearance, because Rimuru, that’s the name of the protagonist in the isekai world, is extremely strong, and even one of the strongest characters ever. And this of course makes this series one of the best isekai anime with an overpowered MC that you can’t miss.
This is so much so that he is recognized by the 7 strongest demons in that isekai world as a real demon king with incredible powers.
