At the age of sixteen Ryo Narushima was a genius and looked to have no trouble of getting into Tokyo University and joining the elite of society. However, that summer something cracked inside Ryo's head. With a small knife he brutally murdered both of his parents only leaving his sister alive and cowering in a corner. It is at this grotesque incident that our story begins.

Extra Note: At volume 20, the series changed publishers, which created a restart of the chapter numbers.

Starting from chapter 61 in volume 26, the first chapter from when the series returned from a long hiatus, the series has been completely written & drawn by Tanaka Akio. While Hashimoto Izou did write the series in the beginning, he had been doing less and less work starting from volume 4. Tanaka & Hashimoto reached a settlement and Shamo continued.

Shamo as an experience

This isn't a manga you read to feel good about. This isn't a manga where the heroes win. This is an escapist fantasy. Read this if you want to blow off some steam and read how one man can be the least responsible parent murdering rapist piece of shit imaginable. Without going into spoiler territory, this manga is rage-fuel up to the very end. It builds rage, creates tension and delivers before repeating. It keeps you interested in how it'll deliver. And then it doesn't, it just ends.
If you're searching for a protagonist you can root for, go away, if you want a world you'd like to live in, find some other manga, if you're in need of likeable characters, tough shit, and if you like your story threads tied up nicely, you're out of luck.

Final Rating: Read it, don't finish it.

Tanaka Akio next time please have the decency to just abandon the series, just drop it, this didn't deserve such a low quality development and sub-par bullshit of an ending, if what you are working is just a work of self hate for what you are making at the moment then just stop, this is an insult to everybody, giving Ryo a girlfriend out of nowhere, weakening him in such a stupid manner making him fight a fucking ballet dancer as his "nemesis" and then have his final opponents be a retarded giant with twin-tails and a stupid big sword is just demeaning, you are shaming this manga, and that end, that end is a joke.

This manga was a solid 10 before the tragedy happened and the author decided to make this some kind of vendetta against his own work. 10 for the main story, but 4 for the latrine that is the rest of this manga.

I had a hard time getting into the heads of the leads or believe the setting completely(i still don´t) but i liked such a nihilistic and byronic voice in the seinen field. But as way too many people mentioned the manga kind of resolved itself and then turns into nonsense when Yan and fantasy shonen crap got introduced after a dozen volumes. Wrong manga dear author ! The art still stayed godlike and convinced me to keep going for a bit but even the fight weren´t interesting anymore shortly after. Worst of all is that Ryo became another man entirely, the music chair of changing leads got frustrating and the drama finaly turned into melodrama. Even the creators started to sue each other !
So you know when to stop to care and read. Would the series ended with the Sugawara arc and a short epilogue i would have given a 7 to a 7,5. Read Holyland for a manga about a believable take on underground fighting and All Rounder Meguru for the best MMA manga ever.

Judging by the art, you expect something great from the first chapters. The story also looks mature.
Taking chapters ten by ten you would find great writing in each batch, but together they're unfortunately a mess.

The Sugawara arc is the best and it's still barely mediocre. The main char doesn't seem to have any redeeming traits or a proper motivation towards why he does what he does.

Once the Sugawara arc is done, you can consider this manga ended, cause what follows is bad bad bad, bad as in you're thinking why you're still punishing yourself by still reading. It's like the author erased the first volumes from his mind and started again from the same spot. For example, our "hero" at one point gets past karate and even learns some new type of martial arts that should put him at the top of the food chain if he wasn't there already just by his strong karate. Pass a couple volumes and he gets beat up in plain street fights, he's weaker than in volume 4.

These kind of things are not plausible but they happen often and where they count most to pull the manga down.

Good art, great fighting scenes, poor story.

RYO IS EVIL ARROGANT COCKY ANGRY STUBBORN everything that is not your typical lead Ryo is perhaps the greatest character written out he has so much depth and goes through so much that it would be impossible for someone to actually be a good person when all was said and done Ryo is on a different level from the akiras gokus narutos ichigos luffys kuronos he isnt in the same category because he is so well written out his character is more real he has no qualms or regrets about what he has done and never plans on it Ryo is a beast what has happened to him and what he does is what makes Ryo RYO

I don't know any byronic heroes like Ryu. I like his character so much I can't describe in words. He changed from a good to evil and soon back to good. I hope he will be saved by his friends (or sister). And I hope there will be no romance (moemi... seriosly? -.-)

And also there's a reason monkey china thing was forgotten just google it.

This woulda been good if the main wasnt such a douche.I never seen a protagonist that's so unlikeable in my life. Maybe the problem is that the author never really care to explain any of his motive.

Why did he kill his parent? Why did he stop looking for his sister? Why did he pick fight after getting out of prison? Why do he go around raping women?

I am still on it but to me it feels like its a manga that has run too long when Ryo and his sister reunited that would have been the perfect ending but the manga has stretched beyond that and the plot has become thinner and thinner and easy to predict example - the moment Yan was introduced I almost knew that she was going to die it was a cheap play at tragedy by the author .
I am going to put it on hold for now and if I feel like it I will pick it up again .

I haven't seen the main character for more than 20 chapters.From a seinen manga with a brutal main protagonist,this turned supernatural, and then the main character is missing and the plot gets also far worse.I don't recall any manga that the main protagonist,where the whole story focuses around him puff disappears.
Spoiler (highlight to view)
Kurohime has 2 main characters
Hunter x hunter the main villain is missing for 200+ chapters

This manga was only good because Ryo Narushima had a cool attitude and now that he is gone the manga is gone down the drain as well.

Stop complaining

Jesus, people need to stop complaining about how Ryo degenerates in the later chapters. Think realistically people.

Spoiler (highlight to view)
The reason Ryo always got stronger and stronger was because he always had to fight opponents that were stronger than him. Whenever he fought people stronger than him he always had a goal (which was to win) and he trained like crazy to achieve for those goals.

Whereas starting from the new chapters, Ryo starts to get weaker and weaker. Why? Because he's always fighting weak losers, he's not getting any training and instead it's becoming a daily chore for him. Not to mention with all the man prostituioning he's doing. He's starting to lose his "wild" nature because he's doing the same boring stuff over and over and you can tell by his expressions that he's damn bored as hell. In the beginning he craved for blood and fights and pain was like his pleasure, but he loses that later because he doesn't feel alive anymore. Not to mention all the guilt that builds on him because he starts to meet everyone that he hurt from his past.

And also you can't expect Ryo to forever remain evil. Yes, he's an asshole, but that doesn't mean he's completely evil. In most cases, he treats everyone like trash, but every now and then you can tell that he still has a human heart remaining in him (like helping his sister). I don't know how the story is going to end up, but it will at least be interesting to see how Ryo changes by the end of the story.
