Whilst I thought very highly of the series, there is very little in relation to it in this OVA. Instead thie is primarily 6 short fan service films for those dying to see their characters in swimsuits, dancing and just in general goofing off. I did enjoy a couple of the shorts and still insist the original series is worth owning, but I think the OVA is a hefty price tag for a very small return in anime.
