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.

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.

This had alot of potential in the beginning. I lost faith in the mangaka when he gave Ryo a path to redemption. I was excited... for one chapter. Then, the story degenerates into ridiculous superpower fights. So dumb.

It's pretty serious and violent. And I dunno if I've been reading too much yaoi or something, but it strikes me as REALLY GAY.

As I am one of the fairer sex, I feel like I should complain about the fact that all the female characters are sex objects except for this reporter chick who's kind of a cold, calculating bitch. But somehow it kind of works.

There's one last thing I'd like to point out -- almost every major character has hallucinations. I don't know if this is just a martial arts thing, but whenever they do something athletic, all of a sudden they're floating in galaxies, or talking to imaginary versions of people. I dunno, if this kind of crap happened to me while I was boxing, I'd probably just get KO'd right then and there.

Shamo was quite good in the beginning, but
it lost its touch when it went too supernatural with
all that levitation bullshit and stuff.

Read up to chapter 164, look at the last page - nice isn't it ? Memorize it cause you won't see it again. After that chapter the manga goes on a slippery slope (to quote the main (anti)hero),

8/10 till aforementioned chapter (deduct 4 after that)

Meh, it had a fairly interesting start and wasn't too shabby at all. However, the story started to fizzle out along the way and it started to have endless fights: sorry but even many series with fighting scenes at least attempt to have some resemblance of plot/story.

After a while, I'd absolutely no idea what was going on anymore and dumped the manga.

This series started out with about being able to survive but now it is like a baki style martial arts manga. The story goes up and down. Is Ryo buff or weak? This is a confusing manga that doesn't seem like the story has a real goal.

The ugly truth of humanity. And Shamo makes it look good.

People will never be completely satisfied. First people compain about stories being to unrealistic. Now they complain about a character that's too human.

Shamo does something that few manga have tried and even fewer have made remotely interesting; and that thing is displaying a realistic world portraying the ugly side of humanity. This manga isn't about growth or overcoming odds. If you want that, go pick up some generic shonen or Naruto (which is great in its own right ). There is "good guy" there is no "bad guy" only people. And that's what makes Shamo unique.

About the setback that was most likely do to the change in serializations and publishers. I got the feeling the mangaka was writing himself into a hole with Ryo getting stronger and stronger everytime; fighting tougher opponents unti lhe would probably end up at DBZ-like proportions. He saw the chance to set things right and jumped on it. I can't blame him.

Toto, you speak out my confusion. How did Ryo degenerate so much? His chinese material arts havent benefitted him in any way. Until now i thought i might just have missed some important part on the story but you approve my suspicion. Its a pity because its not logial for Ryo to downgrade in the way it happens to him.
