Charm can take you a long way in making an enjoyable story, and for everything this series lacks it makes up for with that. If you stop and think about it, the art's not that great and the story really boils down to a clueless idiot continuously pissing off a flat-chested tsundere. Yet despite that it's still a lot of fun. Kyouko and Jiro's relationship is pretty much built on mutual hostility. Hell, everyone's relationship really. But at the end of the day almost everyone's clearly friends. The whole "evil organization" thing is silly and ill-defined. But there's no attempt to take it seriously. No matterhow many flaws come to mind (and a lot do), it doesn't change the fact that I really like this series. The characters interact like friends would (really weird friends, but friends nonetheless) and it never bogs itself down in pointless drama for more than half a chapter at a time. It's worth a shot if you have any love for school comedy series at all.
