Natsuki Subaru gets transported into a magical world where everyone is stronger than him. The only power he gets is the ability to return from death at a certain checkpoint in his life. Compared to his powerful allies, this does not seem to be something with which he can go to a battle. But that is all he’s got, as he constantly blames his weakness for the enormous suffering he is going through.

The anime gets pretty dark very quickly as scenes of death, gore, blood, and violence are very prevalent. Re: ZERO comprises of a total of two seasons with 50 episodes. It is a dark fantasy and psychological anime that is surely different from most others on this list.

2) Mushoku Tensei: Jobless Reincarnation

This story portrays a 34-year-old man who dies as a failure after leading an underwhelming life on Earth. He gets transported into a magical land as a kid named Rudeus, who is a genius in magic from a very young age. He starts training under an expert wizard named Roxy, a young girl. One day while training, a mysterious light comes down and his town gets destroyed. All the people get thrown off into some different place, and it is now Rudeus’s goal to find all his loved ones.

The anime contains a plethora of ecchi references and scenes, thus it might not be suitable for viewers of a young age. But the story is by far one of the best in the isekai anime genre. You will get a touch of freshness from the tale, which takes a break from the usual hero-centric tropes. Mushoku Tensei is 24 episodes long.

3) KonoSuba: God’s Blessing on this Wonderful World!

Satou Kazuma dies in vain as he tries to save a girl from an incoming tractor, where in reality, it was nowhere near her. In his afterlife, the goddess Aqua tells him that he died in vain and laughs at him for his disappointing death. He even wet himself when he died due to trauma. Angered by this mockery, Kazuma chooses to take Aqua along with him to his isekai world, instead of choosing any power. They form a party with two other members, Megumin and Darkness, and go on life-threatening quests as a team of useless characters.

KonoSuba is arguably the funniest isekai anime of all time. The characters and their choice of dialogue offer an attractive and funny setting to each episode, something the isekai fans will surely love. Having goofy characters, even the villains heaves a breath of fresh air to the isekai anime genre. It comprises of 20 episodes and a movie.

Upon receiving and going to a suspicious chess invitation, and of course, winning, the game god “Tet” transports them into a world ruled by games. It is now Shiro and Sora’s mission to defeat the god and rule over the world.

No Game No Life is a show where the world-building and character cast is magnificent. Shiro and Sora are very intelligent and give off a feeling of superiority. This was the show that also started the meme of “No season 2?” as it still does not have one. Fans can only hope for a sequel at this point. It has 12 episodes and a movie.

Overlord captured the essence of being overpowered. As an isekai anime, it never failed to show how dangerous Ainz is as a character and how he can evaporate any enemy he wants.

Van is the prince of this land and is under attack by an evil dynasty. His mission is to protect the kingdom with Hitomi and the help of the humungous mechanical suit, Escaflowne.

The Vision of Escaflowne is the oldest isekai anime on this list as it was released in 1996 and is also the least popular by far. This fact makes it one of the most underrated isekai anime as it chronicles a beautiful story and a very interesting plot. It has 26 episodes in total.

This is one of the best isekai anime on this list. You will love this too if you like to watch a weak protagonist fight it out against all odds.
