You can't have no honor if you can't get up.
I found it strange in the first place that Zoro is willing to take possession of another guy's sword. Zoro must be pretty desperate.
One Piece does tend to bend laws a bit. Zoro doesn't believe in Bushido anyway.
As for the Black Sword, just imagine Zoro putting that into his mouth.
I don't think this fight is over, i think wants to show Zoro in a long drawn out fight where he is really pushed to his limits. And if you notice Zoro isn't wearing his bandanna either.
More Zoro vs. Ryuma please!
Ussop vs. Perona
Poor Zoro he's getting beaten by a skeleton :( I really wanna see some more Zoro vs. Ryuma!
Ryuma doesn't goes seriously againts Brook, may be Zorro doesn't goes seriously againts Ryuma either...
