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.

In 2004 the series moved from Weekly Manga Action to Evening, resetting the chapter count starting at volume 20. It was discontinued in 2007 due to creative differences but returned in 2011.

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

The series' first thirteen volumes were published in Spanish by Otakuland between 2003 and 2005 as Shamo Gallo de pelea.

Shamo is one of the darkest themed and most graphic seinen manga I have ever read. That being said I wouldn't recommend this to the young or squeamish.

“Your light will never reach me!” –Ryo Narushima

Shamo starts with a gory scene of a young boy covered in blood after brutally murdering his parents. Thus we are introduced to the protagonist of the story Ryo Narushima, a boy that was destined to become the elite of his society but becomes a cold-blooded martial artist. After his crime Narushima is sent to Ajigasaki Reformatory, read more

Over the last month or so I've seen a ton of praise for the manga "Shamo" and recently I just read the whole thing and I feel very let down. I thought the first part up to where Ryu cripples the Karate champ in their second fight the story was pretty solid and interesting but after that it just was really lame overall.

Overall the characterization of Ryu just felt like really all over the place and I didn't feel like it was because he was crazy, it just felt like the author didn't know what he was doing exactly with the character and experimented a read more

If it weren't for the manga being on hiatus, I would consider this the true spiritual successor to Fist of the North Star. (Hokuto Shinken)

One has to only look at the first few panels to wonder why I'm comparing this to something more fantasy based as FotNS.

...and I think this is what makes Shamo a masterpiece if it actually had a legitimate ending.

The manga is just pure existentialist material for me.

On one hand you had the basic premise. Shamo shattered any doubts I had that a legitimate exciting MMA manga could be made.

On the flip side, Shamo's failure in doing that, is something that would read more

Recommendable for anyone looking for an easy to follow, dark, action filled psychological seinen, which follows a young troubled protagonist. It's complimented with a visceral and detailed art style.

The story is an interesting commentary on Japanese underground crime culture, following a twisted anti-hero's struggle. It is mainly martial arts orientated and character/fight driven, so anyone looking for an exceptional or detailed story, maybe should look elsewhere. The manga does flow and read well as an outcome of this though.

What it lacks in complexity it makes up for in character development. The mangaka does a great job in engaging the reader with the characters choices, read more
