Books Worth Reading:

1. Re: Monster

Re: Monster

Get It On Amazon

In all honesty, this manga is intriguing. The story begins with the principal character. An ESPIC with a unique ability, which is not common even in the realm of psychic abilities. This ability lets him consume anything and gains abilities from what he eats. This is why, throughout his lifetime, he ate people even if they were evil. this was to enhance the power of their bodies.

Books Worth Reading:

The manga opens with him recounting his demise in which he recounts the way a young girl he knew, who never appeared unsafe and was quite innocent, cut the victim to death with an extremely sharp knife, which slashed the victim with electric shocks.

Although he is with the same weakness as everyone else he becomes an outstanding leader. He is stronger than the majority of people who will attain whatever race. This is the best isekai harem manga.

The artwork is commonplace in the majority of cases even though the characters appear different, they’re not distinctive. Yet. I’m still in love with every aspect of this manga.

2. Arifureta: From Commonplace To World’s Strongest


The plot is going to be a little intense here. I’m sure you’ll enjoy this show. It’s not a bad thing, is it? A funny trio, a cute girl all of it is just your kind isn’t it?

Books Worth Reading:

Hajime Nagumo is a senior high school student who is bullied by his peers. One day, his entire class is transported to an unknown world. The students all get stronger since they acquire the ability to be magical. But, Hajime doesn’t get stronger until he is snubbed by his classmate.

The interesting thing is that the journey begins with him alone. Then, he is to be joined by the vampire Yue Shea, a rabbit girl known as Shea and an incredibly exuberant dragon. 

I don’t believe I need to explain anything more. It’s all clear what’s going on here. It is no 2 on our list of the best isekai harem manga.

3. I Became the Demon Lord so I Created a Dungeon and Spend Heartwarming Time There with Non-Human Girls

I became the demon lord

Rarely do you see this type of manga that has a likable character, an engaging cast (although somewhat cliché), and an overall great setting? 

Books Worth Reading:

The focus is on the characters, so it can be something from a fairytale however, that’s what makes it amazing. 

If the MC were the usual Japanese actor or the characters were annoying, it would feel boring. Luckily, he’s mature and smart and the cast members are an excellent addition, and their interactions don’t feel forced. It flows effortlessly.

A great manga on our list of the best isekai harem manga.

4. Mushoku Tensei: Jobless Reincarnation

Mushoku Tensei Jobless reincarnation

Get It On Amazon

This is a masterwork when you look at it in comparison to other Isekai styles, it stands out. the ecchi is perfect and the MC concentrates on his primary goal.

Books Worth Reading:

First of all, the story is captivating and is captivating, and the use of the page-turning technique of mangaka is awe-inspiring.

Second, the character development rate is 8/10, and the characters are adorable … of them. This particular scene surprised me, as Various was beaten to a pulp in the hands of kidnappers, I didn’t expect this to occur to the heroine.

Thirdly, the art is incredible absolutely and this is one of the best on our list of the best isekai harem manga.

5. Release That Witch

Release that witch

The story centers around the reincarnation of a man as a prince who was spoiled during the age of medieval. 

I have read a few Manhwa’s which have this storyline However, the difference in this story is due to the circumstance of the MC after the time came for him to be reincarnated.

He had been in a dire situation and also at the disadvantage of his enemies. But due to the knowledge of his past life, he was able to rise and fight his foes, with assistance from the witches.

Excellent manga. I like the style of drawing that depicts witches as sexy 😉 The story is also straightforward, but also funny and has good moving. 

Books Worth Reading:

There’s nothing “unique” in this anime just that it uses well-known and well-known formulas and does it with a great level of accuracy which is a plus for itself. A good read on our list of the best isekai harem manga.

6. Chronicles of An Aristocrat Reborn In Another World

Chronicles of an aristocrat reborn in another world manga

The manga is pretty easy to read emotionally. Its main protagonist is extremely powerful and therefore doesn’t face any significant issues that are not solved.

He simply dominates each job he is given. This makes the manga an enjoyable read for the fantasy world of the sandbox.

To be truthful, this is another Isekai episode where the MC is a bit overpowered however, in all truth it’s great and I think it could benefit from an anime. Worth mentioning on our list of the best isekai harem manga.

Books Worth Reading:

7. Trapped in a Dating Sim: The World of Otome Games is Tough for Mobs

Best isekai harem manga

This was much better than I had expected to see. The setting for an Otome game isn’t unusual however they didn’t need to spend so much time on the world’s building. 

Sky pirates. Battles between Mechs. Islands floating on the water. Dungeons. If you can roll in the right setting, it’s a joy. Beautiful girls but not overly fan service-like. A captivating main character as well as an antagonist. 

An MC who sticks to their goals and grows! The translation was, however poor at pronouns. One of the good on our list of the best isekai harem manga.

8. God Of Martial Arts

God of martial arts isekai harem manga

I liked the fight scene as well as the story. The art was excellent, but I don’t like how the main character’s story gets girls to fall for him.

Books Worth Reading:

I would love it more if there was no romance, and he didn’t kill his enemies as he grew stronger and gains more allies.

I went through it and it was fantastic. I was impressed by the art and also characters are tough and will not take any crap. 

I was glued to the book to discover what happened the next time and I was able to sink myself into this incredible story.

I enjoyed reading this manga. It’s one of the best isekai harem manga I’ve read.

Books Worth Reading:

9. How A Realist Hero Rebuilt This Kingdom

How a realist hero built this kingdom

Get It On Amazon

Could contain spoilers:

It’s an Isekai, therefore it’s not unusual that Kazuya (mc) has to be an op. He was intelligent right from the beginning being a realist.

I’m of the argument that he’s not physically op. But that does not make it a cliche. The anime is currently airing, however, the manga is worth more, as its graphic design isn’t like the mangas.

I was impressed by his way of thinking (well since the realist in him Ahah) because he’s not trying to create an earth-sized empire, but merely making the current better but never losing his humility(?)

Books Worth Reading:

Try this manga on our list of the best isekai harem manga.

10. KonoSuba: God’s Blessing on This Wonderful World!


Kazuma Sato happens to be a game-loving shut-in – or at least, he was until a degrading road accident ends his young life an unfortunate end. 

However, after his demise, an attractive girl who claims that she is a god asks him to go into another realm and receive some prestigious perks during the process. 

However, Kazuma’s decision is likely to be a major blow to the goddess and dead man as well. Worth a shot on our list of the best isekai harem manga.

Books Worth Reading:

11. Let’s Manage The Tower

Let's manage the tower

I haven’t read many mangas on management however I enjoyed this one. The MC is not in a hurry, nor is he an ego with extreme traits. I like how he handles things.

He doesn’t seem to have a bigger aim or desire to attain the highest level of excellence, but these things seem to be happening by themselves. 

This can cause the character to appear dull and superficial, but I’m not concerned about that and would rather watch the story unfold to the end, and so far I’m satisfied and excited for the next chapters. Try this because its on our list of the best isekai harem manga.

12. Shoki Skill ga Benri Sugite Isekai Seikatsu ga Tanoshi Sugiru!

Best isekai harem manga

High schooler Shinomiya Raku was reincarnated after an evil god who played with his fate and culminated in his tragic death in the past. 

Reborn is Larucu who is a silver-haired young man with super-convenient abilities he acquired as a token of his apology for his demise and now is filled with the hope of living an enjoyable, easy-going second life. 

But, he was confronted by a string of devastating events, beginning with being kicked out of his family, and then crashing in the middle of the road. 

But because of his honesty and a variety of initial abilities the young man can come out of the circumstances that afflicted him and become the adventurer he’s always dreamed about being.

He is now living his life to the maximum! The curtain is raised on the dream adventure of the child prodigy with endless possibilities! One of the best on our list of the best isekai harem manga.

13. Black Summoner

Black summoner

Get It On Amazon

Are you looking to read an isekai that is a fascinating (semi-cliche) tale? The main character begins with a mighty start and is relentlessly savage to all who are in his path. 

In which, instead of following the rules of ethics and morals the MC is merely one big battle junkie? 

With a diverse cast, where each individual is defined and unique and their interactions with one another can enhance the plot? You’re in luck.

The lighthearted and dark aspects are not discussed, but the issue could appear again in the future. 

The protagonist is a summoner however, he’s also the husband of the god of the literal kind. It’s hilarious most of the time, but amazing at other times. A good read on our list of the best isekai harem manga.

14. I Got Caught Up In a Hero Summons, but the Other World was at Peace!

I got caught up

Get It On Amazon

If you’re summoned to another realm it is expected that things be a certain way to become a hero, fight monsters, and kill demons, aren’t they? 

However, when Kaito receives his summons it’s a little different. For one, he’s not all that much of a hero…but that’s not a problem, since the world he’s placed in is peaceful. 

With nothing else than to be doing, Kaito finds himself taking his time in this surprisingly sweet fantasy world. 

Kaito can now enjoy breakfast with the beautiful inhabitants and learn about magic by collaborating with the spunky demon girl to attend barbeques and much more!

MC finds himself transported to a different world, but he’s not the hero and is not required to save the world. 

He tries to discover himself (tries to figure out what he hopes to accomplish while in another world). 

In his quest for self-worth, He attracts the attention of a lot of powerful women, and that’s where the harem is an integral part of the story making it one of the best isekai harem manga.

15. Demon Lord, Retry! R

Get It On Amazon

This time we’re back with some game-world-related related stuff. It seems that Akira Oono finally decided to stop the server for the game he runs however, it didn’t happen. Instead, he entered the game as Demon Lord.

The moment is now, Akira is in the game of The Demon Lord Hakuto Kunai. This new world that he’s in isn’t the same as the game he managed. It was different. 

Then, Akira, I mean the demon lord, chose to summon people, or it could be called companions who can assist in determining the truth about the game world that he lives in.

You get it isn’t it? He’s a demon lord. He is adored by everyone, and someone with this excellent reputation is loved by gorgeous women, so you’re aware of what I’m talking about. 

He’s like a demon lord who is on a quest with a group of cute friends. It gets a place on our list of the best isekai harem manga.

16. Death Mage Who Doesn’t Want A Fourth Time

death mage

To begin I’d like to say that this is a novel it’s an isekai, but at the very least, it has changed the concept.

I loved the fact that, even though the protagonist was going through agony, he didn’t follow the usual edgy mc path and still hung out with other characters, giving them a helping hand that was prompted by his experiences.

But what I disliked was the balance between dark and comedy I can understand why they were trying to make it funny and dark at the same time, but in certain scenes (like the hunters who took a swipe at his mom).

You’re expecting the character to torture his victims to death over the harm caused to him by his mom, but instead, you are presented with a scene in which people are screaming and make it appear to be amusing.

Give it a shot because it is one of the best on our list of the best isekai harem manga.

17. Death March To The Parallel World Rhapsody

Death march to a parallel world rhaphsody

Get It On Amazon

While the majority of this show is “cliche” and a bit cheesy, it’s also refreshing. If the word “lolis” scares you, don’t let it go due to that.

A protagonist is a refreshing man with morals who views the lolis as his adopted children and will never lay any of the lolis. 

If you’re trying to figure out which chapter to start after watching the series (season 1.) you can start from the 30th chapter and continue from the beginning. 

It is worth trying because it ended up on our list of the best isekai harem manga.

18. How Not To Summon The Demon Lord

Takuma Sakamoto is a fan of gaming, and he’s transported to his most cherished MMORPG game, Cross Reverie. He’s in the form of his game-player character Demon Lord Diablo.

The problem is that he wasn’t teleported. He got summoned by the two women Rem as well as Shera. They both attempted to create Diablo their service but ended up becoming the servants of Diablo. 

Now, he has two gorgeous women as his servants. What else could a man would But, Takuma decides to travel within the world with two servants earning it a place on our list of the best isekai harem manga.
