But that was already liscenced.
Grappler Baki and Air master are nothing but fighting (tournament series). Then there's Flame of Recca, Hunter X Hunter and Mar (manga) if you liked Yu Yu Hakusho and Shurato if you like Saint Seiya or Ronin Warriors.
And Saint Seiya's hades chapter isn't liscenced. That seires is really good. It's all about the gold saints.
