The plotline in this story is incredibly good, if not for the small detail that it often gets sidetracted and the plot is often put on hold to explore evry single side character's personal story, disfunction, and family background. It does so in an entertaining way of course, and will no doubt come in handy near a climax, but honestly, do we need to know about the love affairs of a girl who only shows up for a three chapter vacation arc? In any case, the plotline is entertaining, with a delinquent girl struggling to be more feminine, (and failing miserably) a boy who enjoys fighting way too much (I suspect he was raised as a girl, but that particular plothole is yet to be explained an properly filled in) and a teacher who is more suited to join the yakuza. Not to mention they all form a club to keep the delinquents under control and simoultaneously fight the student council who are attempting to run the school into the ground.
The art is nearly flawless, if not for several characters looking extremely similar, causing confusion in some cases. The characters are wonderfully developed, with complex personalities and backgrounds, no matter how simple they appear from day to day. I love this manga.
