Seiken: Psycho Calibur (1987)

Many years ago there was a country called Earth Maral. One day it was invaded by the forces of the Dark World and torn apart. People lived in fear, there only hope a legend… 'A hero holding a sword will appear and restore peace to our land once again.' No one knew when this hero would arrive… Said the devil beast: What's that? You challenge me? I see. Very well then. I accept your challenge. However, you will never win!
