Part 3 of this live action Hentai series begins with tasty ninja babe Yaku contacting her equally sexy cousins, Seia, Fuka and Maki, for help in her battle against the Shikima sex demons.
After all three of her cousins have arrived, and wounded Bido warrior Miko has been nursed back to health (Fuka applies a special potion to the patient and uses her naked body to thoroughly rub it in), the girls make one last bid to defeat their evil, tentacled enemies.
For those who have already seen the first two instalments, it will come as no surprise to find that part 3 is pretty much the same thing all over again: lots of cute Japanese girls getting naked, taking showers, being assaulted by thrashing appendages, and fighting.
There's also the return of the slobbering delivery guy demon from part 2, who once again gets to puts his tongue to use on one of the girls, a memorable scene in which the gateway to the demon realm is opened through a prolonged stint of self-gratification, and a final battle in which Miko saves the day by rubbing her half-human/half-demon niece Miyabi's chuff!
It's worth watching if Hentai is your particular 'thing', I suppose, but I found the whole trilogy to be a bit on the dull and repetitive side.
