18+ Manga Where The MC Is Weak But Gets OP!

And to that end, we’ve brought you 19 of the best manga out there, where we see a weak main character gaining strength and power over time—even to the extent of becoming overpowered and being able to defeat anyone and everyone in the manga.

And do keep in mind that the list below gives you a brief insight into the stories told in the manga, their genre, and rating. This is just literally a recommendation list for you to go check out.

Well, without further ado, let’s get on the right with it, friend.

Even as human beings, we sometimes want to be recognized among our friends, in school, in our place of work, etc. And that’s just the motive behind Karaboshi Haruki’s story, as he decides to become an adventurer simply because he intends to “stand out.”

One day, the unexpected happened! A dungeon suddenly appeared in Hokkaido, right under his house. And almost coincidentally, he came across a “Skill Board” that he could use to spend skill points to increase his popularity and grow. 

From the odds pitted against him and the uncertainties he has to face, would he be able to get stronger by going into the dungeon every day?

Just how twisted and touching could a story be? I admit the plot of this story isn’t exactly as straight as you’d expect, and that’s what makes it more thrilling. For the main character who got reincarnated in another world, not alone but with many friends, her story reads “ironic.”

She and several students in her school died and were reincarnated in a game world with some skills, except the MC, who didn’t just reincarnate as a spider, but didn’t have any skills. Now that’s just two points against her already.

Check out this fantastic Japanese comic and see how the MC powers up from weak and powerless to becoming OP.

Makoto Takatsuki is a typical high school student who enjoys playing RPGs. Makoto’s statistics are pitiful, and his abilities pale compared to those of his classmates. 

Makoto illustrates that, although when playing on severe difficulties, an RPG player can always reach the end by working hard and utilizing his poor skills in unconventional ways. Powerful gods rule the weird new realm of magic and monsters. Every newbie is bestowed with high stats and special abilities.

In simple terms, this Japanese comic is based on a village where levels are predominant. And aside from the monster hunters, every other regular being is usually between levels 1 and 5. And what’s more? God usually delegates the demon hunters and their roles. 

But the order was altered a little bit one day when a two-year-old Villager boy noticed something. Just what was that? And how does it change everything for him?

In most fantasy manga, Demon Lords are portrayed as the peak of evil. But in this case, it’s our protagonist. To exist in this realm, a Demon Lord must live on the anguish of the victims in his dungeon.

However, our primary hero, Procell, wishes to feed on people’s happiness. And to do so, he decides to build a village rather than a traditional dungeon.

This manga is far more focused on the story and character relationships than anything else, but it’s so much fun.

Shirosaki Reito was unexpectedly dragged in by a strange gap and moved between universes. He became reborn as a baby in a parallel universe. He was born in the royal dynasty and was the successor to the kingdom, but he was thrown out of the palace. 

He started as a Support wizard and had Alchemy as a profession, the weakest career in the new world. Those who had it were deemed unemployed. And that’s just where the whole mystery lies.

In the very employment and skills that Shirosaki has, some mystery will later help him power up and gain more power, so much so that he became OP in such a short time.

Is there anything else I can say to a title like this? The protagonist in this story can kill anyone merely by thinking about it.

While the notion is a little bit ridiculous, the manga embraces it and has some hilarious moments as a result. But just how did she come about this absurd power? Who exactly is she? Well, what’s stopping you from going ahead to go check it out?

Here’s another fantastic recommendation titled, Re: Monster. Even though Tomokui Kanata died young, his experiences are far from over. He is reborn as a humble goblin into a fantasy realm of swords and magic! 

Not one to be deterred, the renamed “Rou” harnesses his new physical capabilities as well as his previous memories to make progress in a world where eating other animals grants him access to their strengths and abilities.

Before I tell you about this manga, I’d like to ask you this. Imagine that you had to spend much time mastering something so that you’d be recognized for it. And after a while of living in the fame of that thing, something better came up, and you realized you’re the weakest amongst your peers. How would you feel?

Well, that’s the story of Zeff Einstein, who spent several years practicing red sorcery and was finally acknowledged for it. However, a new spell that was shortly devised revealed that his skill for red magic was the weakest

Bitter at the notion of all his lost effort, he prepares a spell to transport himself back in time to his younger body. Alongside the ambitious “genius” magician, Milly, and the lovely swordswoman, Claude, he vows to study magic more effectively this time.

I think now that should give you a perfect picture of why this Japanese comic is a perfect recommendation, as you’d get to see how Zeff Einstein powers up, to the point of becoming an OP Sage.

Despite that the title of this manga is pretty much a mouthful, there’s something I’ve come to love about manga like this. It’s the very fact that the titles sometimes give you a near-perfect picture of what to expect before even starting to read it. 

For someone that gets paid to kill slimes, I think it’s more sufficient to say the main character even used to have fun while working. But how did the protagonist in this story grow from being weak to becoming one of the top fighters in the story? Now that’s an assignment I’m giving to you.

Even I am surprised by this. If the Main Character had reincarnated as a little kid, or as an opposite gender, or a ghost, or something else, it’d have made sense. But reincarnating as a sword? Now that’s on another level.

But as the story goes, even as a sword, he still saved a young girl named Fran from slavery, and she, in turn, became his wielder. Since Fran wants to get stronger and become OP, and the weak sword MC also wants to know his purpose in this world, the duo set out on a fantastic adventure.

How ironic can it be to see a “Classless Prince” in a world where people are ranked based on class. I can only say that’s a massive blow to Leon, the Magic King, and his wife Fara, the Sword Princess. And yeah! Prince Arel, the Classless, is their son.

How would life be for him in this world where Arel literally has no importance or even class? You could only imagine how miserable 10-year-old Arel would be to find out that he would have to live without being in a particular class. 

Now this fantastic Japanese comic has given us the beautiful story of how Arel stuck to the belief that even without a skill or job, he could still persevere through consistent effort. And suppose you’re looking for something to motivate you while also getting entertained. In that case, I highly recommend that you read this manga

In a magical world, indeed, everyone can’t be equal. There would be the mages, the learners, the semi-skilled, and even those without magic. So, no doubt, everyone would be respected and classed based on their magical strengths, right?

And for the main character that’s completely weak, as he can’t use magic, Mash felt his only other option was to become a fitness god, which he did become. But later on, he had to enroll in a magic school to learn to use magic, and indeed, he was met with a crazy competition there. 

Just how would this magic-less, weak MC fare? How would he learn to survive? And would he become strong at all, and just what are the trials he would face? Trust me, this manga is one of the fantastic ones you’d love to read, bro. 

So, don’t dally on this and go, cop, your copy of this exciting manga.

This manga is more directed at and based on high school life and ordeals. And it is one of the reasonably popular manga out there, which if you haven’t yet read, you surely would’ve heard of.

But who is the weak main character that later started becoming OP in this fantastic Japanese comic? Well, his name is Hajime Nagumo. And here is his story. 

Hajime is an ordinary high school student living everyday life with his friends. But all that changed when he and his classmates were whisked away into another world where they were called upon to serve as heroes. On the other hand, Hajime lacks the attributes and talents of his peers. 

He stumbles into the bowels of a monster-infested pit unprepared and underappreciated, and he is forced to choose between hunger and sacrifice. His only choice in this harsh world is to embrace the depths of the abyss.

You could deduce that the main character in this manga is some overpowered protagonist, even from the title. But a sweet irony of that is in the fact that it’s his avatar in his favorite game that’s strong. But in real life, he’s just one lazy and unproductive young man. 

After living all his life doing nothing but making his game avatar become number one in a game, his account was hacked, and he lost all the progress he’d made. Filled with despair, he committed suicide, but woke up, reincarnated in the same game he used to play, but as a forgotten alternate character he’d prepared sometime back.

Now here’s the gist. This manga tells a weak character’s journey with several unique game characters and tries to become OP. And what else makes this a better recommendation? The very fact that the manga is set in a game, almost like Sword Art Online. Hahaha!

This manga has a pretty quick story for a Japanese comic that falls in the adventure and Shounen genre. The way the main character rose in power and fame was pretty quick, but believe me, when I tell you this, it is EXTRAORDINARY!

For an influential and well-known sage, Gaius took a bold step when he decided that reincarnation was the best way to get another Crest. And he did it. He committed suicide and woke up in the body of Matthias some few thousand years in the future. 

Now he’s devastated to realize that he has the weakest Crest in all of the town and now has to do all it takes to power up and become stronger to fix all that’s befallen the entire human race.

Well, now, we have another manga where characters are respected and categorized based on class. And for Rentt Faina, who’s been dreaming of being in the Mithril-class, life has not been fair to him in the past ten years that he’s been on the adventure.

But his dreams were shattered when he got eaten in a Labyrinth by the Legendary Dragon that lives there. Sometime later, he opens his eyes in another place, but no longer as a human, but at a SKELETON!

But awakening as a skeleton didn’t deter him, as he still intends to power up and become OP, even as a living dead. And that is why I’d put it to you that you should get a copy of this manga, and feel the burning desire that our weak skeleton MC has in his journey to gain more power.

Hmm, Black Summoner. Now this here is one great manga you’d love reading. But where does it all start? It all starts when Kelvin wakes up in a completely different place with no recollection of his past life. He discovers he’s traded those memories for powerful new abilities. 

As a Summoner, he enters a new world, and his first Follower is the goddess who migrated him over! Kelvin starts his new life as an explorer but soon discovers his hidden desire to fight. With each formidable foe, he relishes the fight. Join this OP adventurer and his allies as they carve their way into history!

And the last item in this list, the Ichiban of manga, where we see a weak Main Character later powering up over time and becoming OP, is none other than…

I wouldn’t even be surprised if you say this is the only manga you’re familiar with on this list. But why not? It is one of the most popular manga that even newbies would’ve read before they can be called a weeb. But what’s so unique about this manga?

This manga stands out in art, plot, character development, and other criteria. But what exactly is this manga about? And why is it topping this recommendation list?

This manga is about Satoru Mikami, a weakling and a loser. Satoru is a lazy bachelor who likes to spend his free time sitting in front of his computer. But all that came to an end when he was stabbed on a sidewalk, died, and woke up in another world.

This is an entirely magical world filled with flying horses, mages, goblins, talking wolves, and other fasntasy creatures. And this is where the story gets exciting. How about you go on and grab a copy of the manga and see how Satoru Mikami becomes Rimuru Tempest, a weak slime who goes through different trials and later becomes the strongest and most intelligent creature in his world.

What's Your Fav MANGA?
