Welcome to AnimeExpert, and here’s my scrap metal list of popular as well as underrated Isekai anime that you should be watching. 

10. The Eminence in Shadow

Top 10 Popular as Well as Underrated Isekais Anime

When you ask someone to describe a show that has the most thrilling plot and deepest character, this anime is not what they were talking about. Eminence in Shadow is the cringiest, edgy, power fantasy anime you will ever watch, and you’ll ask yourself, What am I doing with my life? If the other Isekais on this list were to be described as Michelin-starred meals, this anime is McDonald’s, and I love it. This anime is about Sid Kagenou, a high school student who dreams of becoming the ultimate mastermind of the shadows. 

Cid believes that the best way to achieve this goal is to live a double life, pretending to be a normal student by day, aka an NPC, and a shadow mastermind by night. He recruits his childhood friends, Ninomiya and Yasuoka, to be his loyal henchmen and embark on various missions to prove his worth. Cid is a skilled strategist and tactician, as he uses his knowledge of manga and anime to plan out his schemes. However, his plans often involve him bullshitting his way through, which would end up being real and lead him to ridiculous situations. The series is full of over-the-top comedy as well as fully embracing tropes and cliches. It’s the definition of cringe. As the series progresses, Cid’s reputation as a shadow mastermind grows, and he gains the attention of various shadow organizations that see him as a potential threat. Overall, this series is a fun and light-hearted anime that pokes fun at its genre while telling an engaging story. This is something worth checking out.

9. Sonny Boy.

Top 10 Popular as Well as Underrated Isekais Anime

Sonny Boy is a story about 36 high school students who suddenly and mysteriously had their high school building transported into a void-like dimension. Lost and confused, the student council attempted to impose control and order on the students. Though some of them awaken supernatural powers, it would lead to division and conflict within the group. We follow the perspective of the main characters, Mizuho, Nagara, and Nozomi, as they deal with unique challenges and obstacles, traveling to different dimensions and solving conflicts to find their way back home. 

Sonny Boy is different compared to most of the Isekai in the genre. Its story and characters are very complex and complicated, which causes a lot of confusion for the viewers. It’s difficult to predict where the plot will take you next, and it might take some of you to sit through it a second time to grasp the tip of the iceberg of what the story is trying to tell you. But don’t let this be the reason to stop you from watching this. Several factors make Sunny Boy an interesting show but I think its main selling point is its characters. It introduces a wide variety of characters with different motives and personalities. Some of these characters provide different perspectives on certain issues and morals, which makes the story very compelling and interesting. 

The numerous mysteries and different philosophies of these characters cause drama and conflicts to arise, which is what makes it so intriguing. Every episode is different. It’s messy, complicated, and sometimes pretentious; it requires you to be patient to understand what’s going on. But everyone has a different opinion or take about this anime. Some say this is a masterpiece and others would say this is boring, and neither of them is wrong. Sonny Boy is an anime where you take what you can get and that is how you would perceive it. It gives a unique experience to the viewers, something not many shows can do. This anime is not for everyone, but I strongly recommend giving it a shot. 

8. How a Realist Hero Rebuilt the Kingdom

Top 10 Popular as Well as Underrated Isekais Anime

If you are looking for a more political, city-building isekai, this is the perfect one for you. This anime follows the story of Kazuya Souma, a high school student who gets summoned to a parallel world to become the new king of the Elfrieden Kingdom. Upon his arrival, he discovers that the kingdom is in a state of disarray, plagued by economic problems and political corruption. Using his modern knowledge and management skills, Kazuya implemented various policies and reforms to revitalize the kingdom’s economy and infrastructure, including creating a central bank, establishing new trade routes, and improving agriculture. This anime is Civilization 6.

 Along the way, he would face resistance from the nobles and military, who disagreed with his ways, but his persistent attitude and determination would aid him in building alliances and forming new friendships that would make the kingdom a better place. The series explores themes such as leadership, politics, and diplomacy. Kazuya’s pragmatic and rational approach to problem-solving sets him apart from the typical heroic fantasy protagonist, making him an interesting and unique character. This anime has amazing world-building and lovable characters; it steps away from your traditional adventure isekai and does something more unique and interesting, making it a must-watch for both isekai and fantasy fans.

This is a fantasy anime series that follows the story of a group of strangers who find themselves in a strange world with no memories of their past lives.

The voice acting is also excellent, with the actors delivering emotional performances that add to the depth of the characters and their relationships.

Top 10 Popular as Well as Underrated Isekais Anime

If you ever wondered what would happen if a Roman soldier went against modern guns, look no further than Gate. Gate follows the story of a Japanese Self-Defense Force (JSDF) officer named Youji Itami. Whoever, at first glance, seems boring, lazy, and a weeb is a talented and hardworking individual.

A reverse isekai would happen where monsters started pouring out of the gate and started farming the humans for xp, the JSDF was able to establish control and wipe out the monsters. They would explore the new world and set up a military base, pretty much like modern-day British colonization. Itami would lead a reconnaissance team through the gate to explore the new world.

 Throughout the series, the JSDF team becomes involved in various conflicts, including defending civilians from a dragon attack, rescuing hostages from a band of rogue knights, and uncovering a conspiracy involving the Empire, the ruling government of the fantasy world.

After dying in one of the most embarrassing ways, he meets a beautiful goddess named Aqua. He turns out to have a few loose screws and is pretty much useless. After being reincarnated into a fantasy world while forcefully bringing the goddess with him, both of them would have to work hard and overcome different obstacles to survive and make ends meet.

Top 10 Popular as Well as Underrated Isekais Anime

This anime follows the story of Subaru Natsuki, who was suddenly transported into a fantasy world with an interesting ability. He discovers that he has acquired the ability to return to a “save point” every time he dies. Though it might sound OP at first, it has its downside. He would often have to go through emotional hell to simply survive after dying multiple times. He would befriend and follow a silver-haired half-elf girl named Emilia. Along with other characters, including the loyal maid Rem and the mage Beatrice.

 He learns more about Emilia’s past and becomes determined to protect and prevent her tragic fate, leading him to face numerous trials and adversaries. He also learns the true nature of his power and the consequences of abusing it. Subaru dies multiple times, and each time he returns to life, he tries to change the outcome of events to prevent further tragedy. However, his actions often have unintended consequences and lead to even more dire situations. Subaru is forced to confront his flaws and shortcomings, including his tendency to act impulsively and make mistakes. He must learn to confront his faults and improve himself as a whole if he hopes to survive in this new world and protect those he cares about.

 Throughout the series, Subaru forms alliances and builds relationships with other characters as they navigate the intricate political landscape and encounter various individuals with their motivations and secrets. The series is known for its complex plot, character development, and emotional depth. It tackles themes such as love, loss, trauma, and redemption. This is why this anime is heavily recommended for Isekai and fantasy fans.

1. Mushoku Tensei.

Top 10 Popular as Well as Underrated Isekais Anime

It is a fun and engaging anime with amazing characters in an immersive world. This anime follows the story of your typical 34-year-old shut-in Discord mod. After being kicked out of his house, he received a visit from Truck-kun and was reincarnated in a new fantasy world as a baby. Formerly living his life with fear and regret, Rudeus Greyrat, now named Rudeus Greyrat, decides to take his second chance in life and redeem himself. The pacing of the show in the beginning is slow. Rudeus would spend most of his time training with Roxy and overcoming his trauma. The anime wanted to take its time to set its foundation for the world. It has a combination of movie-level animation and cinematography, as well as telling an engaging story. This anime will take you on a roller coaster as we get to experience rich character development and intense fighting scenes. However, our main character, Rudeus, has a lot of issues and is the center of controversy. 

The anime does not shy away from showing him as an absolute scum. But with the main theme of this anime being redemption and growth, as time goes on, viewers get rewarded with amazing character growth, not only from Rudeus but from everyone around him. This is a character-driven anime, and you might even get attached to some of them, as it does not fail to make every character we meet through his adventure seem so special. Aside from the characters, it has one of the most immersive worlds in anime. From beautifully drawn cities with different cultures to their very own translatable language, it is all you could ask for in a fantasy world. This anime may take some viewers a while to get used to, but I promise it will be worth it.

That’s all I have to say. Although there are plenty more isekai in the genre that I wasn’t able to fit into this list, such as No Game, No Life, Log Horizon, Overlord, Shield Hero, and many more, I just wanted to share with you guys my favorites first.
