Well this was your typical fan-service OVA. Personally bummed on how Hanabusa was treated here, but then again, if you watched the main series, you would know just how damn strong she was, so I guess they had to make her not as strong as before. Aside from the fanservice, there is really nothing much else to point out except for the ending song being good, the animation quality being good as before. Oh, and as for plot, the plot is basically the girls are fighting over these pin/badges. Thats it. Nothing else.
