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.

Note: The series has been completely written & drawn by Tanaka Akio from ch.61 in Vol.26, which was the first chapter after a long hiatus, and the original author Hashimoto Izou wrote less and less starting from Vol. 4.
The series changed publishers, which lead to a restart of the chapter numbers, with Vol.20.

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.

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.

The story is pretty good, but the art and especially the character design make this one work. It does not really matter to me when the story goes off track, because the manga is so stylish. Like watching a Takashi Miike film.

There are so few mangas that pay attention to art. (Some shoujo looks as it it is drawn by a kindergarten kid with crayons.) But graphic fiction is graphic fiction because of the interplay of the written word and the images that accompany them. In the US we get the opposite problem---all art no story. It is nice to get a balance.

This manga had me going to bed satisfied everyday. It was gory, violent and extremely good. There were many scenes that pissed me off, but it was interesting to see a strong main character fighter, who's just damn evil.. Then the story went supernatural and just completely sucked from then on...

What a shame for shamo to end up sucking sad

This manga is an excellent story; our mangaka writes such a powerful story, that, despite our (not hero) protagonist, his amorality, and his lack of any self control (or even better, preservation), one can hardly let it be, once started. The fighting is first rate, and is well worth it. The scenes of rape and violence are, indeed, quite difficult to get over, and I would prefer not to have had to read those, but, despite my aversion for them, these make the story what it is. As disturbing as that may be.

I quite agree with Isara that it is very draining. But I must be quite the masochist, because some of my favorite stories are the draining ones... (I might add that I do love a "pump" manga, but which leaves the bigger impression, I might ask? Pain, or pleasure... [Pleasure only leaves a bigger impression when it's through an addictant. Sorry. =| ])

Ryo is such an awful person, it hurts to accompany him on his path to whatever he will be in the end (most likely dead).
The few light moments of moralty and emotionality could not carry me over the vast scenes of him raping women and being arbitrarily violent towards strangers.
Still, this take on martial-art is very captivating and I wouldn't believe it if there was a nice person in Ryos place.
This is the major plus of Shamo, it's dark and unfriedly yet not entirely hopeless view on human nature. Not to forget the superb fighting scenes, especially when he fights against people superior in skill. Another clever idea, not to create a main charakter with flawless technique and outstanding talent. Everything looks like hard work possibly not worth the effort (where did it take him anyway).
The art fits and there is beauty from time to time.
Better not read it at the end of the day though, since most of this drains every last positive feeling out of the reader.

I'm with the other people here. This story and the people in it are very ugly, but completely gripping. It's a great premise. The main character did something so unforgivable that "decent" people and criminals both instinctively hate him. Essentially, the whole world wants him dead - but he refuses to die.

For a while, it's a fantastic story. And then... Well, it goes completely off the rails. Is it gritty and realistic or shounen supernatural? Is Ryo a true monster or is he basically a decent guy? Is he weak or is he strong? From one panel to the next, you can never be sure. It's really confusing.

I'm still reading to see how it ends, but the series really went some bad places along the way.

that i really appreciate. i reccommend it to anyone who likes seinen.

if i had to describe it, I'd say it's a twisted (and gory) take on an underdog story.

i personally find these stories to be a huge cliche but this manga definitely takes the genre in a different direction.

Redeption? What are you talking about? I didn't see anything like that. Ryo is still going down. Where the hell did you stop reading?
And about "superpowers", I admit that part in China was meabe little off (stoping hearts, kung-fu-movies-like training) but still not impossible.
