Her name has changed from Katsumi to Katsuni (for strictly almighty $ reasons) and her body type also transitioned from natural to siliconed, but this typical Michael Ninn spotlight on the talented French/Vietnamese performer is probably only of historical interest now. I bought it and watch it as a fan of the "old" K, but she has much better work out there including story features.
I see that IMDb has decided to list her under her real name, an annoying policy that solves nothing. It would be like listing Tony Curtis as Bernard Schwartz or Marilyn Monroe as Norma Jean Baker - a stage name (= best known as) should rule in a database.
Overlong all-sexer is the usual posing and humping segments, with several other femme performers thrown in for variety. But Katsumi certainly is alluring to watch in different costumes and guises. Guest star Mia Smiles is also credited with Wardrobe, so she should share the credit with Ninn for the results. She and Katsumi run through a live-action version of the popular Japanese porn fetish for adults dressed up like school girls (ponytails not optional but required), and it's as boring as the rest of the program.
The music and editing are tedious, but K in a variety of thigh-high boots plus delivering her usual d.p. action should satisfy ardent fetishists.
