Cosmic Heavenly Demon 3077

Story:

Qi, swords, and martial artists. What about robots and spaceships?! The year is 3077, thousands of years after the peak of martial arts activity. Humanity lives among the stars, governed by interplanetary martial arts groups that uphold the realm's ancient rules: might makes right! For bounty hunters like Seryeong, Robert, and Sunja, danger is excellent for business, except when they take on more than they can handle. After traveling to the irradiated wasteland of Earth for a high bounty, they encounter a 2,000-year-old martial artist and understand their fortunes are about to change.
