Battle Vixens, Volume 2 Book

I'm not sure when this book was originally published vs. Tenjo Tenge, but the more I read, the more this came across as a poor man's version of the latter: same concept, similar characters and designs (EDIT: a fan actually listed comparisons side by side of the two mangas, showing scenes and poses that seem to very closely resemble those of TT, if not outright plagiarize them) with none of the charm, the interesting backstory or characters: the main protagonist wins fights always in the same way (she gets her ass kicked, has a sudden moment of going psycho and levels up, then proceeds to kick ass). The story is convoluted and complicated unecessarily so, and the world build is boring.

I'm reading a friend's colection, fortunately, as this is definitely not worth my money.
