The quality of the art, animation, and fight choreography as a whole deserves mentioning; especially considering it's almost 20 years old. It was all done so well, that the OVA barely shows its age.
Yuka's match with Jun is one of the highlights of the series, combining an awesome fight sequence with cinematics and special effects. Jun's "KubotaSpecial", in particular, is as awesome to look at, as it is painful to watch.
During her match with Satomi, she casually counters a fully enhanced ki powered strike, by offseting the flow of ki from Satomi's attack, nullifying it. All while lecturing her on how she was doing it as though it were simple, and even made it look easy! With skills like that, it's no wonder she's the reigning champion.
