This OVA basically just feels similar to some of the better episodes from the main series. By that I mean it has a nice balance of comedy, fan-service, and sweet moments. And the animation seems to be a bit better than the main series. The story isn't Shakespeare, but if you watched the main series I imagine you already know what to expect. So if you watched the show, then this OVA is a no-brainer. After I watched it, I felt stupid for putting off watching it for so long...
Edit: So apparently they made another OVA! I finally got a chance to watch it recently, so I thought I should update this review.
I didn't like the second OVA quite as much as the first, probably because it revolves around Hijiri, who wasn't exactly my favorite character in the show. It still delivers the comedy and sweet moments, but unfortunately no fan-service this time.
