As I heard that the manga and anime are different, and as I remember almost nothing because of so many years have past since the watch-through, I decided to read the manga.
And well, story is not particularly clear, the plot is still confusing, though the historical summary before every chapter helps a bit.
I would say, that if you want to see naked girls fighting each other read Sekirei. The storyline is clear, characters are compelling, overall it has a wholesome atmosphere.
But if you want the fights to be brutal and don't really care about the plot, then yes, stick to Ikkitousen.
Another con is the characters, especially design. You have Kan'u Unchou, or Ryomu Shimei with great design. You have some loli girls. But overall all the girls have same physique but diferent face and hairstyle. On a panel showing them naked you hardly distinguish them.
Overall, this manga can be fun, but don't expect much and enjoy for what it is worth: boobs and fights.
PS. And why I even writing this review is to ask you not to read it in TokyoPop version. It has butchered translation. Trying to adapt the narrative to Western audience, they changed dialogs, including pop culture references to American culture. They have 4rth wall breaks, where they shouldn't have been. But the most awful thing their translation is a ton of sexual remarks made by male characters, where they are not in the original.
The speech of every character drives the plot, and does notexpress sexual appeal.
