Top 20: Best Isekai Anime That You Must Watch (2021)

Isekai anime is one of the major genres when it comes to anime shows and you are going to find tons of shows, both good and bad, within minutes. Since there are hundreds of titles to go through, it become a bit tedious if you want to find the best ones and not waste your time watching literal trash. This is the reason why I created this list featuring only the best isekai anime titles!

The anime medium gives an exaggerated perspective on things that we would otherwise consider normal. The reason for this is to resonate with audiences and provide them with a fresh take on things we’re all used to seeing, like basketball, martial arts, and even cooking. Religion is no different. One of Japan’s primary religions is Buddhism, and one of its central teachings is reincarnation. The possibility of having a second chance at life is something many people dream of, and those clever folk in Japan made sure to capitalize on this.

Isekai translates to “another world” and is the most versatile genre in anime. It perfectly captures the majesty of being whisked away on an adventure, with new opportunities awaiting you at every turn, at the cost of a fateful encounter with truck-kun. Whether a fantasy world with magic and creatures of legend or a cyberpunk dystopia that’s on the brink of collapse, you’re sure to find something that tickles your fancy. And in this list, we’ll be going through only the best of the best.

Best Isekai Anime of 2021

As a bonus, Touya can bring one item with him, and he chooses … his smartphone!

Our protagonists find themselves in the mystical world of Grimgar, with nothing but their names and the will to live. There are no do-overs here. With all the strong individuals teaming up together, Grimgar follows the tale of a party of weaklings who can do nothing but fight for not only their survival but that of their new home.

The common trend in most of the top isekai anime is the protagonist being whisked away to another world. But what happens when that world comes to you? Re:Creators explores a fresh take on the genre in a world where the characters of popular stories, whether video games, light novels, or even manga, mysteriously come to life.

Reiki Kawahara’s mega-hit series is often regarded as the father of modern isekai anime shows. Sword Art Online takes place within the MMORPG virtual reality space of Aincrad. On launch, hundreds of thousands of users are loaded into the game and soon meet a nightmare they can’t imagine. The game has transformed from a straightforward fantasy adventure game into a dance with life and death. Each player now has one life, and when they die in the game, they die in real life as well.

6. Re:ZERO – Starting Life In Another World

re:zero - starting life in another world

For most, starting life in a fantasy world would be a dream come true. Incredible abilities, fame, fortune, and even a cute heroine are the trademark package granted to the protagonist of the popular isekai anime. However, none of these rules apply to Natsuki Subaru.

Re:ZERO revitalized the isekai genre by giving its MC only one ability; the power to restart at a fixed point in time whenever he dies. The catch? He remembers and experiences all the pain that comes with dying and can’t tell anybody about it. This masterfully crafted tale involves many races such as elves, demons, and even a witch cult. It is perfect for those who wish to experience a fresh take on isekai and a new interpretation for the entire anime medium.

5. KonoSuba: God’s Blessing On This Wonderful World

konosuba: god's blessing on this wonderful world

The story begins with a professional neet (a shut-in essentially) that believes he’s risked his life to save a random passerby but instead has died a truly laughable and truly humiliating death. Our hero, Satou Kazuma, should be showered with respect and praise, but rather, he’s mocked by the goddess in charge of his reincarnation, Aqua.

When tasked with saving the world he’s going to be reincarnated in, he is given the option of choosing one power to take along with him. Seeking revenge, Kazuma chooses Aqua as his wish, and the two face some of the craziest and hilarious situations a fantasy setting has to offer. KonoSuba is an anime that will have you smiling from ear-to-ear at all times!

4. Log Horizon

The players of MMORPG “Elder Tale” soon find themselves trapped within the world of the game they’ve been playing for years, inside the body of their avatars. We experience the narrative through the eyes of Shiroe, a master tactician and veteran of the game.

Though initially confused, Shiroe soon finds his long-time friends Naotsugu and Akatsuki, and the trio seek out to make sense of their situation. Log Horizon is a grounded isekai anime filled with a vast cast, a broad range of politics, and a unique approach to the “death game” idea.

3. No Game No Life

no game no life

“In every world, in every time, the strong polish their fangs, while the weak polish their wisdom.” No Game No Life is a beautifully written adventure of a brother-sister duo codenamed “Blank.”

They are the best gamers globally, yet they can’t seem to fit into it. After unknowingly beating a God at a chess game, Sora and Shiro are welcomed into the world of Disboard. Games govern this place’s very laws, and with the best gamers set free into this playground, even the sky is no limit for these two prodigies.

2. The Rising Of The Shield Hero

One day our protagonist, Naofumi Iwatani, discovers a book that will change his life forever. This book details the adventure of a hero who wields a shield as his only weapon. Before he can think any further, Naofumi finds himself transported to a palace surrounded by three other heroes and a people who seem like royalty. He also notices there’s a shield stuck to his arm!

The Rising of The Shield Hero is a woeful tale of a misunderstood man, betrayed, and admonished from society. Despite all this, however, he is still a hero and is keen to remind the world of this. Indeed, this is a tale of a hero’s rise.

1. That Time I Got Reincarnated As A Slime

Satoru Mikami is your average single 30-year-old. While out with his subordinates from the office, he is stabbed by a mugger and dies on the spot.

The moment he regains consciousness, Satoru confirms that he’s alive, but also… he’s a slime!
