oh yeah. I have volumes 1-10, but got that at tjtg.mangatranslation.com before the manga got licensed by DC comics (which the site removed the torrent), and will try to help find it for you.
There is some stuff from the manga that hasnt been on the show, gratuitous nudity, and a well-done design.
*on nudity, when you watch the show, it's plainly obvious when they are censoring or reanimating a certain sequence*

The thing of it is, though, the anime is only 26 episodes, and the manga has expanded to 12 chapters. Im not even sure if its over yet.
It's not like Naruto where the anime plays catch-up w/ the manga, thus allowing the show to put more into the show, then say a series that is 26 eps. I guess it cant be helped.
*shoulda made the series 52 eps.*

Budweineken: the opinion on the main character I formed was before I read the manga. I speak from an anime standpoint. One would think to be that hes the central character of the series, cause of the recent events, and his claim to be the strongest in 3 months.

QUOTE from Hyuga koji: In the beginning yes but later on it begins to focus more on the jyukenbu as a whole.

Souichirou doesn't show up for more than 3 volumes.

The series doesn't revolve around Souichirou and Aya they get more screen time than other characters but it is not their story.
