hmmmm....I've read the first few volumes in the store but I don't buy it. The translation is just awful. All the unecessary cursing and during the fights when in the Japanese text the name of the move that is being is used is written but the english text says some completely random crap.
I'd say that it's a good manga, just in Japanese though. Never buy the english one.
FYI: The actual title is "Ikki Tousen".
