Pai energy is the life force from big boobs; fighting evil with its strength are five well-endowed young women known as the sexy rangers.
Big Boob Squad: Sexy Rangers features a group of ample chested Japanese cuties in skimpy colour-coded outfits fighting alien monsters, and at just over an hour long, really shouldn't have been a chore to watch. But it was.
The plot sees the wicked Muscle Kingdom attempting to invade Earth, with Queen Amorous and her minions hoping to harness Pai energy for their own nefarious needs; this leads to them trying to abduct one of the sexy rangers (I'd go for the blue ranger, played by gravure idol Yuzuki Aikawa).
Badly choreographed and extremely dull fight scenes between the busty ladies and poorly constructed 'monsters' ensue (Camerang, a creature with a camera for a head, being the silliest), with time out for the sexy quintet to frolic in bikinis on the beach (easily the best bit).
3/10.
