Hmm I'm not sure if they'll be enough to talk about in each section that's all... Things are looking a bit messy at the moment though.
As for the drama... It is pretty low budget. Also I'm afraid it doesn't stick to the story very well either. Like the anime it tries to cram a lot into each volume, infact it's often worse than the anime in that regard. Characters and events are altered pretty harshly in majority of the volumes. For example the storylines are covered like this:
Volume 1:
The First arc (Ayumi and Mariko) combined with the Fumiya arc
Volume 2:
The Nanno/Katsuyuki/Takezawa arcs all combined into one
Volume 3:
The Midnight Angels arc
Volume 4:
The Natsu arc (Well... if you can still call it the Natsu arc without Kamata being in the show at all)
Volume 5:
The Atsukiyagyou arc combined with the Kadena arc (dont ask me how they pulled this off)
Also fight scenes... Sorry but they're not so great either. Expect crap, often cartoony sound effects and fake-looking acting... Although the Atsukiyagyou hand carving was done alright. Blood. Yay

Anyway. Even all that said, hell, it's still Shonan Junai Gumi.
