Imagine a series made of characters oblivious to what they're doing and how it looks, focused around toxic masculinity, with a healthy dose of sexism.

It's basically a story about who's the biggest asshole with the hugest dick around, with some really moronic extra pretense "plot" surrounding it.

Good thou cliched start but unfortunately the main setting is forgotten and all you are left is yet another crappy story about school delinquents and the like fighting meaningless and boring fight over who is the biggest d*ck in town. Not to mention after 300 chapters you get a very crappy and hurried ending that solves nothing and is very open. There were only a few likable chars too, a few of em female and one guy (can't remember korean names... they all mix in my head).
The one thing I really liked here was the art and fluency of the action in it.

the author wrote himself into a corner and then it became had fight after fight between character that don't mean anything. As others have mentioned, first 1/2 to 2/3 was good.

btw, they never change back bodies......

started good then went downhill.
i think i was more disappointing because it had such great potential; if it had sucked from the beginning i wouldn't have expected as much from it.
not on my list of fighting mangas to recommend to others. unless you're pissed off at them for some reason. save your time.

It is really nice fighting manga (nice at least for the fist 2/3 of it), and even being a female did not hold me back. I've read all of it, and the one thing is clear - this is totally for those who like weak-to-strong category. Some fights however proved to be extremely boring, since they did not feature the two main characters, and I am not into reading several chapters of some guy fight.
As was pointed out by someone earlier, there is practically no women in here, which is just like fleeing from reality of denying the existence of half of the population. It is understandable because of a genre chosen, but still unbelievable.
The ending was rash, but nice and leaved me with a light feeling that you can do everything if you put your mind into it. Still ending was terrible in a way that it did not answer any questions and featured some characters not even in mentioned.
The last ark was dreadful, just fighting and no development, plus unexplained weak-to-strong jump. To bad.
I recommend it to the guys who like fighting manga, but not to the extent of knowing much of a details.

Worst comic ever!

It starts out with some potential and reminds me of angel desu. but after about 10 chapters, it degenerated into a battle manga. New characters keep showing up, but old characters are discarded. There's only 5 female characters making up 5% of this comic and the rest are dudes (excluding the female scientist). I hate leaving things unfinished, so after 2 volumes, I just flip through it and understood the gist of it.

The two chicks look exactly the same and you think the editors would have caught that before it was plublished. But they cut her hair afterwards to differentiate the two. If this was publish in a japanese magazine, it wouldn't have lasted more than 2 volumes.

Please lord, return my time wasted reading this POS.

If you are the type to want to see a story to its happy ending (as most of us are) you should read this series anyway its addicting plus its completed which is usually an upside for those of us who hate those cliffhanger moments

The plot has to considered weak and the story development was also very poor. At time I thought a 10 year old was writing it . But since it's an action manhwa so it's all about the fights and honestly they are pretty decent but again as the story progresses the theme of 'next guy-stronger-than-the-last' becomes so obvious you can predict the next chapter from a mile away.

The ending was poor and rushed but I guess the Koreans stopped buying it so can't fault the author much for the pathetic last 3-4 chapters . The damage to the story was done much earlier.

I would recommend if you have a free weekend and just wanna read something you will forget by the next .

The original storyline was great. He has no idea what's going on and has to make his mind's knowledge of martial arts catch up to his body's. There was even some romance.
Spoiler (mouse over to view)
the real delinquent wakes up
, that's when that it goes downhill. The entire last arc is just...well entertaining at frist. had some good fights. then it gets ridiculous and....shit, i guess bigrazz
The love interests don't come back and it's no longer about the nerd trying to learn martial arts or adapting to his body or whatever. Neither of them even seem to care or mention that they've lost their lives. i don't even remember why he was fighting at that point.
So, when the

other guy wakes up
, drop it. Especially when they get to the island. then drop it like Russell Crowe dropped that guy with cancer.

I didn't actually read all of it. i dropped it a few years ago in the middle of that last arc, couldn't be bothered to keep up with the scanlations. Wasn't worth it.

Very Very disappointing

This manhwa was good until you get to the middle of the manhwa. The initial plot that original drew me in deviates completely. I was really hoping that the story would get back to the original plot, but it did not. Some characters that I thought would reappear in the manhwa did not at all. The character development is mediocre and the fighting scenes were decent. There were barely to none romance in this manga so bakaupdate should take it out out and put it as a subplot at least.

Now, to the worst thing about this manga. As you read through the last arc, you can tell that the manga is being rushed to end. Everything suddenly starts to be explained in the last 2 or 3 chapters. It was funny that the last boss or strongest guy loses to the main character in one freaking chapter. Now, the ending was the most disappointing thing in this manga.

If you are the one of the people that hate reading crappy manga endings, this is it. The ending has no closure at ALL!!! After 300+ freaking chapters, the author couldn't even end his manhwa decently.
Spoiler (mouse over to view)
In the end they do not even switch back at all. I was also hoping some one would find out about their secret but none of them does. The two scientist we see at the very beginning does not show up again in the manhwa. The story ends when both of the characters are seen wanted on a poster so people are trying to find them to get a reward(if I remembered correctly) so the two characters get ready to fight them. That was all....

Overall, good manhwa that goes downhill like most 300+ chapter manga/manhwa. Don't read this manga if you do not want to waste hours of your time and feel unsatisfied in the end.
