Full screen. Dubbed into English. Prior owner rated the image "VG/EX," no doubt by VHS standards.

From a review on letterboxd.com:

Slave of the Sword is a steamy sword flick with nipples to spare. Heavy on intrigue and drama and kissin' and sucklin', but when it comes time to throw down it’s no slouch by any means. Great swordplay and wirework and competent fighters all around. It’s short, sweet, and to the point (that point often being thrust into the flesh of some unfortunate foe).
