If you watched both seasons and still have an itch for more of the Samurai Girls this might or might not scratch the itch. It's definitely in the side story category, the girls are competing to Muneakira's wife, and seeing how much fan service they can generate. There's no real plot no real story just a bunch of silly fan service scenes. Unfortunately the art isn't as good the main series. It's taken a definite downturn in quality. The backgrounds seem more computer generated or just had less effort put into them. The characters were definitely not as well drawn or animated, a real disappointmentwhen so much of this was fan service.

Unfortunately there doesn't seem to be an English dub of these ova, so I can't comment on the voice acting. The music is about on the same level as the original series if not a little better.

TL:DR If you made it this far through these you'll probably enjoy these.
