 If you liked
Shamo
|
 ...then you might like
Garouden
|
Both mangas revolve around martial arts and the people who practice them while contaning plenty of graphic violence. None of the main characters from either story is what one would call "a good guy", they are driven by their ambitions, and they don't mind stepping over the bodies of their competitors.
Garouden can in many ways be seen as a somewhat less character-driven and a more shallow version of Shamo.
