Kunoichi senshi ninja

Three cute, sexy ninjas, around the age of 20, have been in training, building their powers for some vague future threat. Their destined mission becomes apparent when a handsome ninja from 400 years past drops from the sky into the hot tub of on of the girls. He comes with news of a grave threat: an evil industrialist has apparently joined forces with UFOs to take over Japan. The only solution, it seems, lies in the special talents of the three girls - notable as much for their martial arts as their skimpy costumes.
