Dragon Against Vampire (1985)

Black Dragon wields his evil menace, and nobody knows who or what he is until he begins to leave a trail of blood and horror that proves to all that he's a vampire preying on virgins. Nobody knows how to rid the town of his pestilence, especially since he's endowed with superhuman powers that enable him to quash any foe. But enough is enough, and the town is determined to rise up against him.
