I had gotten behind so I just finished reading this volume. One thing that blows my mind that I never saw anyone discuss in this thread was Akatsuki carrying an unconscious Kawanami around school ... and nobody questioning it. a) what the hell did she do to him (we never got an answer) and b) why did nobody care? And c) he's been described as a decent-sized guy, so we're getting more hints dropped that she's really strong, which they keep doing every so often.
In any case, she's annoying as hell, so it was actually nice to see less of her than usual in this volume.
EDIT TO ADD: I just saw the cover of Volume 8, and Kawanami and Akatsuki are on the cover, and he, indeed, is huge compared to her. That must have been quite the sight seeing her hauling him around like that.
