Isekai anime are common nowadays because of the unrealistic tropes they have. The isekai genre pertains to the shows where the protagonist ends up going to another world for various reasons. Usually, it’s by dying in his/her original world and getting reincarnated in another. Summoning the protagonist is also common. With that in mind, it’s customary for most of the protagonists to have an unusual power at the start of their isekai life, which makes them stand out. Many people love the ones who are extremely strong, aka overpowered, and so I’m here to feature some of the top isekai anime with OP MC characters.

Taichi was summoned to another world because of the massive magic power that resides within him, together with his best friend, Rin. Taichi, the MC in this isekai anime, is very OP in terms of the amount of his mana. However, he doesn’t know how to properly use it, and something drastic has to happen before he can unleash his true powers. If you are fond of an isekai with slight romance and an OP protagonist where you can’t predict what is going to happen because he can’t unleash his full potential, then you must give this anime a try.
You can also watch the trailer below:
Nishimura Taichi is a typical, average high schooler, and Azuma Rin is a beautiful woman with the build of a model and excellent reflexes. The two live a normal high school life until one day they’re suddenly enveloped in a mysterious magic circle and transported to an unknown land. That world is full of terrifying monsters, beastmen, dwarves, elves, and many other races right out of fantasy. In order to survive in this new world Taichi and Rin decide to become adventurers, but when they take the aptitude test they discover they both possess cheat level magic…Crunchyroll
Isekai Cheat Magician aired in the Summer 2019 anime season and it had a total of 12 episodes. An OVA also aired in July 4, 2021. You can watch it on Crunchyroll.
Seichi is an overweight kid who is always getting bullied in his school because of his appearance. That said, he is a kind-hearted teenager who won the affection of his caring seniors. One day, all of the students from their school except Seichi get transported by God to another world to become heroes. God noticed that he overlooked that Seichi exists, so as compensation, he gave him a special ability and transported him separately to a different part of the world where he could get stronger than anyone else. There, he eats the fruit of evolution and suddenly becomes handsome. Not only that, but he also acquires some skills whenever he thinks about them. Surely this is enough to say that he is really an OP MC in an isekai anime. He can do whatever he wants because of this feature. However, whenever he acquires a certain skill, it makes him less human.
When I say less human, it doesn’t mean physically, emotionally, or mentally. It’s like he is different from all of the people in the world and they cannot reach him in terms of intelligence and power. Another thing that is interesting in this anime is that the main heroine is formerly a gorilla who transformed into a beautiful girl. Since there’s the main heroine, it means that there’s a romance. However, as the story progresses, the MC encounters more romantic interests which possess different traits. So if you are interested in an isekai anime where the OP MC is continually evolving along with his harem, you might enjoy this show. You can watch the trailer below:
High school student Hiiragi Seiichi is bullied by his classmates for being a “loser.” One day, his entire school is suddenly transported to a video game-like world of swords and sorcery. When he accidentally eats “the Fruit of Evolution,” his life as a successful “winner” beginsCrunchyroll
The Fruit of Evolution aired in the Fall 2021 anime season and it had a total of 12 episodes. You can watch the anime on Crunchyroll.
This isekai is very unique because the cause of the protagonist’s death is god itself, and it was an accident. Touya Mochizuki, the OP MC of this isekai anime just accepted it since he couldn’t really do anything about it and it’s not like he can go back to Earth if he wants to because that is the rule. However, he can be reincarnated into another world and Touya wishes to bring his smartphone with him. It allows him to search for anything he can find (like searching for food recipes not available in that world). God agrees with this and grants him a body that won’t easily die like last time. God also gives him high magical power since his smartphone is powered by his magical power, meaning he needs to have a lot of magical power for his phone to constantly operate.
He also has a high aptitude for all six elements (fire, earth, wind, water, light, and dark) which he discovers when he tests it together with Elze and Linze (harem in the new world). It is known that having an aptitude for two elements is considered a genius and having three is called rather unusual. In this world, there is also non-elemental magic or null magic depending on the translation, which is unique to its user and learned automatically, which Touya doesn’t have. However, he quickly learns his own non-elemental magic [Gate], which allows him to shorten the distance between two places, like a teleportation device.
He also gets his hands on a book that contains all the null magic ever recorded, mostly useless to everyone. But for Touya, it is a gift since he can just activate any null magic as long as he knows what it does and its name. The only thing that prevents him from completely subjugating the whole world is his personality. He is benevolent enough to forgive a god who cost him his life in his previous life. Touya is also chivalrous enough to save anyone without expecting anything in return, which is the reason he gets his harem as most of them are rescued by him. He also has a sadistic nature (which he is not aware of).
I would say that this isekai anime is generic because the OP MC has a harem and his powers are common. However, his cellphone and its use makes it unique as well. So if you want an isekai anime with a very techy and OP MC, together with a slight romance, you should watch this show. You can also watch the trailer below:
After dying as a result of God’s mistake, the main character finds himself in a parallel world, where he begins his second life. His only possessions are the body that God gave back to him and a smartphone that works even in this new world. As he meets all kinds of new people and forges new friendships, he ends up learning the secret to this world. He inherits the legacy of an ancient civilization and works together with the kings of some very laid-back countries on his carefree travels through this new world.Crunchyroll
The MC, Sakamoto Takuma is the strongest when it comes to the MMORPG game Cross Reverie. He is using Diablo (Demon Lord) as an avatar. He then gets summoned by two beautiful girls into another world similar to Cross Reverie with his avatar form intact. He also has all the skills and powers of Diablo from the game: his castle, maze, and any other mysterious and powerful matter he made in Cross Reverie are also in that world. Therefore, he knows everything and what needs to be done in every situation. The two girls who summoned him to accompany him on his adventure and having both of them around of course means ecchi scenes for the anime.
If you want an isekai anime with an OP MC who has a lot of knowledge and experience, this series is for you. You can also take a look at the trailer below:
Sakamoto Takuma was so strong in the MMORPG Cross Reverie that his fellow players came to call him the “demon lord.” One day, he gets summoned to another world in his avatar form, and meets two girls who both insist that they’re the one who summoned him. They cast a spell used to enslave summoned beasts on him, but that activates his unique ability, Magic Reflect, and the girls end up being the ones put under the spell! And thus begins the otherworldly adventure of a demon lord (pretend) who blazes his own trail through overwhelming power.Crunchyroll
The first season of How Not to Summon a Demon Lord aired in the Summer 2018 anime season and it had a total of 12 episodes. The sequel of the series titled How Not to Summon a Demon Lord Omega aired in the Spring 2021 anime season with a total of 10 episodes. You can watch both seasons on Funimation and Crunchyroll.
Death March to the Parallel World Rhapsody
Satou is a game creator who often dreams about being inside the game he is working on. One day, he wakes up in another world and thinks that it is a dream since the features he put for the game’s main character are still intact. Well, it is safe to say that it is really the game he is working on but, of course, it is not a dream and he is really in another world. Since the features he put are there, he knows how to use them, naturally making him an overpowered MC. Satou can also upgrade his skill from level 1 to level 10 depending on the situation. I think it’s safe to say that he is in control of everything.
The anime is fun to watch because the MC is smart and humble. He is not the dense-type OP MC that you can typically see in the usual isekai out there. Satou is also caring for all of the humans in that particular world. In reality, he is 30 years old, but in that world, he is 15. He is also popular with girls and it’s fun to watch whenever he says “I would probably fall for her if I was 15 years younger”. He also has a harem but he is not falling for them and he treats them like family, while he sets his eyes on one girl only.
If you are fond of an isekai anime where the OP MC is very chill despite having a very troublesome but wholesome harem, you should watch this show. You can watch the trailer below:
“Satou,” aka Ichiro Suzuki is a programmer in the middle of a death march. He was supposed to be taking a nap but somehow wakes up in another world… What lies before him is what looks like the menu screen of the game he was working before his nap. He’s at a complete beginner stage at level 1. However, he had three “Meteor Showers” which could level a whole map. Suddenly, a whole group of lizardmen appears in front of him. In order to survive, Satou uses Meteor Shower, his level jumped to 310 and he became extremely wealthy. Whether it be dream or reality, Satou’s journey was now beginning.Crunchyroll
In this gender-bender isekai, the MC is originally a salaryman working in a human resource department where he oversees firing employees for the sake of the company. He is doing it efficiently without any regard and empathy towards them. One day, after firing an incompetent employee, he was pushed by him to death which leads him to meet an entity that he called Being X. The MC is a rational person who follows logic and reasoning, which is why he doesn’t believe in any metaphysical beings like a god, especially Being X. Enraged by his faithlessness, Being X sends his soul into a harsh trial where he will have to ask the god for help. He woke in an orphanage as Tanya Degurechaff, reincarnated into an alternate universe in the nation called the Empire.
Tanya lived her life in the orphanage peacefully until someone from the Empire checked each child if they had any magical aptitude, which Tanya had. Having no choice but to enlist in the army, she decided to rank up into the higher-ups to enjoy her life behind the scenes away from the front line and raise a big middle finger to the being that proclaims itself to be a god, Being X. She then rose up the ranks and became the second lieutenant. As a child, she lacks physical attributes which make her weak in close combat. However, it is compensated with her magic, strategic mind, and ruthlessness. As a former salaryman who often disregarded emotions to prioritize the company, she is efficient and is ready to cast away anyone she deems incompetent.
Tanya is also an adept manipulator due to her innocent-like appearance, which she is not afraid to use when a situation arises. If you want an isekai anime with a badass OP MC and military-like battlefield, then you should give this anime a try. Watch the trailer below:
It is June of the year CE 1923. A young girl with blond hair and blue eyes, Tanya Degurechaff, has entered the final curriculum of the Imperial Military Academy and is training at the third patrol line in the northern military district, the Norden Theater, as part of her service to the force. Her training, the first step toward a brilliant career as an aviation mage, should have gone off without a hitch… but things took an unexpected turn.Crunchyroll
The Saga of Tanya the Evil aired in the Winter 2017 anime season, and it had a total of 12 episodes. A movie sequel came out in February 2019. A second season for the series has also been announced, but there is still no information on when it will air. You can watch the show on Funimation and Crunchyroll.
Lugh Tuatha Dé is one of the text-book perfect OP MCs in isekai animes out there. He was the finest assassin on Earth when he was alive. However, he was betrayed by his organization. The goddess summoned his soul and told him that he will be reincarnated in another world to assassinate the hero. There he realized that this is an opportunity for him to live a different new life. All he needs to do is to assassinate the hero. Because of that, he picked all of the necessary skills he needed to become powerful enough to kill a hero. As a result, he can recreate different weapons that can be found on Earth. Since the new world focuses on magic and it seems the setting looks like the renaissance period, the people there don’t know about the modern assassination tools that were being used on Earth.
Lugh is also upgrading the tools he creates, improving their power for greater killing efficiency. Since he is an assassin, he knows everything about the human body and he knows how to make it strong. His movements, especially in combat, are also outstanding because of his experience. Lugh also has a harem but he only has feelings for one girl. The author of this anime is Rui Tsukiyo, who is also the author of the controversial Redo of Healer.
If you love the works of Rui Tsukiyo and you want an isekai anime with a very cold and calculated OP MC, then The World’s Finest Assassin must pick your curiosity. Unlike most other isekais where the goal is to kill the demon lord, the protagonist here is an assassin and he must kill the hero. It also has a fair amount of romance. Watch the trailer below:
The greatest assassin on Earth knew only how to live as a tool for his employers—until they stopped letting him live. Reborn by the grace of a goddess into a world of swords and sorcery, he’s offered a chance to do things differently this time around, but there’s a catch…He has to eliminate a super-powerful hero who will bring about the end of the world unless he is stopped. Now known as Lugh Tuatha Dé, the master assassin certainly has his hands full, particularly because of all the beautiful girls who constantly surround him. Lugh may have been an incomparable killer, but how will he fare against foes with powerful magic?Yen Press
High school student Haruto died in a bus accident and got reincarnated in a fantasy world. It seems that one of the strongest high-ranking spirits resides within him so he has a massive amount of magical power. When he was still a kid, he nurtured his magical and sword skills to the point that even skilled adults cannot beat him. He can also fight equally with spirits, who are greatly superior to humans in terms of spiritual and magical powers. Seirei Gensouki is an anime where the OP MC is smart and chill. He got betrayed, which led him to leave his home. On his travels, he meets many people and stays with each one of them for a while.
There is also what they call Hero’s Summoning, wherein people from Earth are summoned, which is different from the MC because he got reincarnated. What’s more, all of the girls in this show are cute and there’s a slight romance here. So if you want an isekai anime where the OP MC is living like a lowkey hero in a pure fantasy world, skilled in both magic and sword, then you have to give this show a try. You can watch the trailer below:
His past life and current life are intersecting–a boy with memories of two lives faces his destiny! After his mother was killed at an early age, the orphaned Rio fought his hardest to survive in the slums. One day, he awakens to the memories of Haruto Amakwa, who died in an accident while dreaming of being reunited with his childhood friend, and Rio realizing he has reincarnated in a world of swords and sorcery.Crunchyroll
Seirei Gensouki: Spirit Chronicles aired in the Summer 2021 anime season with a total of 12 episodes. A season 2 has also been announced for the series but there is still no information on when it will air. You can watch the show on Crunchyroll.
If you love isekai, but at the same time, you’re not interested in the world the OP MC came from, then Arifureta is perfect for you. The isekai anime starts with the OP MC Hajime already in another world, and the scene where they were transported can only be seen in the opening song. The protagonist in this series was transported along with his whole class, together with their homeroom teacher. Unfortunately, he was betrayed by one of his comrades and it is one of the reasons why he is the only overpowered among them. You might think that he trained so hard for revenge, but he didn’t. The show also contains some romance, harem, violence, fantasy, and huge character development.
The OP MC here is not dense. He is very intelligent and the moment he decides something, even if he is going to kill someone, he will execute it immediately. For me, Hajime is one of the best isekai protagonists out there because of the way he does things. It’s clear that even though he has his own harem, Hajime is loyal and only loves one girl. So if you want an isekai where the OP MC won’t make you feel annoyed, then Arifureta is for you and you can watch the trailer below:
Hajime Nagumo and his high school class are suddenly summoned to a fantastical land as heroes. But while most of his classmates have powerful stats and abilities, Hajime does not. Underappreciated and unprepared, he tumbles into the depths of a monster-infested dungeon where voracity and sacrifice are his only options. To thrive in this savage world, he’ll have no choice but to welcome the abyss.Funimation
Arifureta season 1 aired in the Summer 2019 anime season, and it had a total of 13 episodes. Two OVAs also aired in December 2019 and February 2020. The second season of Arifureta is currently airing in the Winter 2022 anime season. You can watch the show on Funimation.
Tsukimichi: Moonlit Fantasy is an isekai anime where the OP MC, Makoto Misumi is ‘ugly’. As a result, the goddess of the world where he got isekai’d turned her back on him. She even revoked Makoto’s hero title and forbid him from interacting with the humans in her world. Because of that, another deity gave him a new power, much stronger than his original one. He was able to have his own harem and interact with demi-humans because of those powers. On the other hand, the humans see him as a monster with a massive demonic aura behind his back. What’s more, his powers also let him build a village. The story of this anime revolves around Makoto’s journey to learn the secret of the world along with his harem and village-building together with different demi-humans.
There is also a bit of economics in this isekai anime since the OP MC decides to become a merchant. If you happen to have an interest in an isekai with a not-so-good-looking OP MC but still has his own harem and a bit of village-building, economics, and adventure, then Tsukimichi: Moonlit Fantasy might be for you.
You can also watch the trailer below:
Makoto Misumi is just an ordinary high school student living a regular life, but all of a sudden gets summoned to the other world to become a “hero.” The goddess of the other world, however, insults him for being different and strips his “hero” title, before casting him off to the wilderness at the edge of the world. As he wanders the wilderness, Makoto encounters dragons, spiders, orcs, dwarves, and all sorts of non-human tribes. Because Makoto comes from a different world, he is able to unleash unimaginable magical powers and combat skills. But just how will he handle his encounters with various species and survive in his new environment. In this fantasy, Makoto tries to transform the other world into a better place despite the humans and gods having turned their backs on himNippon TV

Wise Man’s Grandchild
Wise Man’s Grandchild is one of the generic isekais out there where the protagonist dies in an accident and then gets reincarnated in another world to have amazing powers. Merlin, the hero who saved the kingdom and is known as the wise man, raised the MC of this isekai anime, Shin Wolford. Because of that, he inherits some of Merlin’s powers and techniques, making him invincible. When he turns 15 years old, he enrolls in the academy where he meets his own friends and love interest. Although this isekai has generic traits, an interesting thing is that he doesn’t have a harem.
Since there’s a huge gap between his own powers and friends, he decides to train them to learn combat skills. This anime also contains a very fluffy and wholesome romance. So if you are fond of an isekai with an OP MC and a wholesome relationship with his friends and lover, then this anime is for you. Watch the trailer below:
A young man dies in a car accident and is reborn in a magical new world. The old, yet wise Merlin finds the boy, names him Shin, raises him from infancy, and teaches him combat and powerful magic along the way. 15 years later, Shin is ready to travel the globe on his own, but Merlin forgot to teach him something major—common sense!Crunchyroll
Wise Man’s Grandchild aired in the Spring 2019 anime season, and it had a total of 12 episodes. You can watch the series on Funimation.
One day in Japan, over 30 thousand Japanese gamers suddenly disappear. When they wake up, they find themselves inside the game that they were playing, “Elder Tale”. One of them is Shiroe, a socially awkward college student. Shiroe is a skilled veteran in the game as he’s been playing the game since he was in middle school. Because of his knowledge of the game and his knowledge of political science, he puts his brain to work and tries to make a peace-offering government to unite all gamers who are trapped inside the game. The MC in this anime is OP in terms of intelligence and tactics, and he overcomes the obstacles using all of the skills and knowledge he possesses.
If you want an isekai anime with an intelligent OP MC, then this show is for you. Watch the trailer below:

The trapped players are still alive, but they remain in combat with the monsters. The players don’t understand what has happened to them, and they flee to Akiba, the largest city in Tokyo, where they are thrown into chaos. Once proud of his loner lifestyle, Shiroe forms a guild called Log Horizon with his old friend Naotsugu, female assassin Akatsuki and others.Crunchyroll

No Game no Life is a very unique isekai because it doesn’t revolve around an MC that needs to physically fight other beings. Instead, the new world only focuses on games, and whenever you need to fight, you have to do it using a game. This anime is an isekai with a smart MC who is an expert at games, which makes him OP in the world where he got isekai’d together with his sister (who is arguably even more OP). No Game No Life is very interesting because you can’t predict what’s going to happen as it involves all kinds of games. It’s already hard enough to survive games that use fantasy while not having any magic themselves. What’s more, the opponents will use whatever means to win, regardless of it being cheating.
The MC really has some crazy ideas that you can’t really think of in a normal game, which makes him and the anime badass. So if you want a very unique isekai with OP MC, No Game No Life is perfect for you.

After the instant hit of a DMMORPG called YGGDRASIL due to its extremely lifelike virtual interaction, the time has come to end the game permanently.

The MC Ainz Ooal Gown is analytical and thorough, can lead his troops exquisitely, and can even learn an infinite number of skills due to his skill “Dark Wisdom”. Despite being alone, his companions love him so much, especially his overseer Albedo and the 11th Floor’s Guardian, Shalltear Bloodfallen, battling for the heart and loyalty of Momonga.

The Devil Is a Part-TImer is actually a reverse isekai anime. For those who are not aware, a reverse isekai is when the protagonist transports from another world to Earth. The MC of this reverse isekai anime is the demon lord of Ente Isla, and he is really OP. He was nearly defeated by the hero, Emilia Justina, and escaped to Earth together with his loyal servant. Now he is working in a restaurant as a part-timer because he needs money. However, it seems like the hero followed him to Earth, and because of various events, they found a common enemy. Thus, they ended up fighting together, protecting each other’s backs. Though it doesn’t change the fact that they are still enemies, they can’t exactly make a ruckus on Earth.
As time passes by, they slowly get closer to each other without realizing it. While watching the anime, you might wonder if the two main characters will have a romance in the future. That said, there is still another girl (normal human living on Earth) in this anime that they meet. Her name is Chiho and she is a co-worker of the demon lord. Chiho greatly influences the story of The Devil Is a Part-timer. Every arc and scene in this anime involves her, even when the demon lord Maou or Emi are making decisions, they always consider Chiho’s situation. You might wonder if this will be a love triangle in the future with waifu wars running in your head.

This anime is very tricky in terms of whether it is an isekai or not. Apparently, the demon king Anos Voldigoad was reincarnated after 2000 years in his own world. However, it is not the same world as it is because a certain person changed the order of it, making the world new a few years after his death. Since Anos Voldigoad is the demon king, it is given that he is the strongest demon alive in the demon realm. His magic surpasses every other being and he can take down a whole castle if he wants. He can also effortlessly resurrect the dead and uncover some mysteries. There are spells that only he can do. The story of this anime revolves around Anos, together with his subordinates, Misha, and Sasha Necron. They want to uncover the mystery of why the people don’t know his name and why they are worshiping a different demon king instead.
There is also a romance in this anime but it is between the side characters of the series. So if you are interested in an action-mystery isekai anime where you can’t see a single glimpse of weakness within the OP MC, you should give this a try. Watch the trailer below:
Anos Voldigord was a tyrannical Demon King that eradicated humans, spirits, and even the gods, but became bored of eternal warfare and reincarnated with dreams of a peaceful world. However, what awaited him in reincarnation after 2000 years were descendants who became too weak after being accustomed to peace, and all sorts of magic that deteriorated to the extreme. Anos enters Demon King Academy that gathers and educates those who are viewed as the reincarnation of the Demon King, but the academy could not see through his true powers and ends up branding him as a misfit.Crunchyroll
The Misfit of Demon Academy has 1 season with 13 episodes, which aired in the Summer 2020 anime season, and you can watch it on Crunchyroll. Season 2 is also confirmed, and it will release its 1st cour in 2022.
The Hero Is Overpowered but Overly Cautious, or Cautious Hero for short, is another unique isekai anime out there, together with its OP MC and a good plot. Goddess Ristarte summons Seiya to defeat the demon lord of a certain S-Rank difficulty world. However, he is unbelievably cautious to the point that he needs to train every time they are about to go to a new place. Sometimes, it takes more than three days before he finishes training because of his overly cautious self. Right at the start, he even spends a lot of time and energy to kill a slime, and even uses one of his strongest spells to make sure it’s dead numerous times.
Seiya has a lot of mana, but even spending a small piece of it makes him really conscious. He also gets more subordinates and he really cares for them in his own way. Though he is not good at showing his true feelings. There’s also romance and some surprises, and it’s definitely worth a watch! You can watch the trailer below:
In the world of Gaeabrande, Goddess Ristarte is tasked with summoning a hero to save her world. The hero, Seiya Ryuuguuin, is an OVERLY cautious hero who’s obsessed with muscle training and buying armor before setting out to deal with low level creatures.

He eventually befriends a powerful (tsundere) dragon and claims the name, Rimuru Tempest. Although he is often seen as a low-level slime monster, Rimuru still has his human values. Plus, he actually has some handy skills that allow him to eat, absorb, and mimic other monsters and their powers. He is able to defeat even Disaster rank monsters, a threat which small nations would usually have no chance against! He also meets reliable allies of different races and skill-sets too. In the course of his journey, Rimuru becomes extraordinary as he builds from scratch his own friendly nation of monsters. That also means overcoming bigger obstacles, enemies, countries, and Demon Lords.
A highlight of the show is, of course, Rimuru’s unique character– an overwhelmingly overpowering slime. Another thing about Rimuru is even if he has no gender, a lot of people (girls mostly) are actually very fond of him. If you want an isekai anime with an OP MC with fascinating and epic world-building, skill trees, battles, feels, and fun humor – you definitely have to add this show to your watch list.
Corporate worker Mikami Satoru is stabbed by a random killer, and is reborn to an alternate world. But he turns out to be reborn a slime! Thrown into this new world with the name Rimuru, he begins his quest to create a world that’s welcoming to all races.Crunchyroll
That Time I Got Reincarnated as a Slime has 2 seasons. The first season aired in Fall 2018 to Winter 2019 anime season and it had a total of 24 episodes. A total of 5 OVAs also aired in 2019 and 2020. Season 2 aired in the Winter and Summer 2021 anime season, which also had a total of 24 episodes. A movie was also announced. You can watch both seasons on Funimation and Crunchyroll.
This isekai anime has a really dark plot. Four people are summoned from different worlds to fight the Waves of Catastrophe and become heroes. The MC of this show, Naofumi Iwatani, was summoned to another world to become the Shield Hero along with the three others, the Spear, Bow, and Sword Hero. Unfortunately, he quickly suffers a major setback and ends up having a difficult start. However, this helps him become stronger and build a unique party. It is also fun to watch because Naofumi uses weak monsters to threaten the people that betrayed him.
Naofumi was a very kind-hearted person and he was able to form his own party despite being treated as an outcast by the people. He follows the path he wants to, and he slowly opens up to his party and believes in people again. The Rising of the Shield Hero is one of the best isekais out there. Each of the characters has their own development. There’s also a bit of romance in the anime, but you can barely notice it. There are also so many mysteries that might blow your mind at the ending of the series, so be prepared for it if you are planning to watch the show. You can also watch the trailer below:
Iwatani Naofumi, a run-of-the-mill otaku, finds a book in the library that summons him to another world. He is tasked with joining the sword, spear, and bow as one of the Four Cardinal Heroes and fighting the Waves of Catastrophe as the Shield Hero. Excited by the prospect of a grand adventure, Naofumi sets off with his party. However, merely a few days later, he is betrayed and loses all his money, dignity, and respect. Unable to trust anyone anymore, he employs a slave named Raphtalia and takes on the Waves and the world. But will he really find a way to overturn this desperate situation?Crunchyroll
Problem Children Are Coming From Another World, Aren’t They?
I’d say Mondaiji has the strongest OP MC among all isekai animes out there because the protagonist can destroy the “power itself” of the character. Izayoi, the protagonist of the series was summoned to another world together with Asuka and Yo. All of them have unique powers and came from different worlds. Izayoi can destroy things with one hand. He can also destroy things by throwing something with a very great force as if his hand is a canon. His punches and kicks can even defeat a god. Asuka can control the minds of other people, while Yo can talk to animals and she can also copy how they move, which is very useful in fighting. Mondaiji is very interesting because the new world utilizes the principles of games, similar to No Game, No Life. The only people who can live in this world are the people with unique powers. That’s why the game pertains to a clash of parties, and people can die there.
The different characters also represent different myths and fantasies known on Earth, such as the Piper Pipe of Hamelin or Halloween. When the characters go to fight those beings, they first need to uncover the mystery of the myth they represent in order to be able to beat them. Some actual gods also live in the fantasy world such as Indra and Buddha. There are also three waifus in this isekai anime, and one of them is a bunny girl. The series also has comedic scenes, especially because the protagonists are “Problem Children”, meaning they were always up to no good, forcing the bunny girl to discipline and baby-sit them. So if you are interested in an isekai anime where different myths in the world meet together with an OP but troublesome MC, you must watch Mondaiji.
You can also watch the trailer below:
Three problem children – Sakamaki Izayoi, Kudou Asuka, and Kasukabe You – suddenly receive an invitation to another world known as “Little Garden” from a girl called Black Rabbit. Battles, laughter, sex appeal… anything goes in this new tale of adventure!Crunchyroll
Problem Children Are Coming From Another World, Aren’t They? aired in the Winter 2013 anime season. An OVA also aired in July of the same year. You can watch the series on Crunchyroll.
Let’s conclude! Isekai anime has really gained popularity over the past decade. It also spawned some “isekai-like” anime such as Sword Art Online, Full Dive, Accel World, and more titles. I’d say that it is safe to expect that we will be seeing more isekai anime in the future as companies continue to profit off the latest titles in the genre. One of the elements that make isekai anime awesome and interesting for many is the fact that they have overpowered (OP) MCs. One thing is for sure, fans aren’t likely to lack isekai anime in the near future!
