When the Rhineist organization is obliterated in a bloody corporate ambush, dying commander Robin entrusts his household and state secrets to Caesar, the legendary cyborg gunfighter known across star systems as Mr. Machine. To evade mercenary armadas, Caesar masquerades as a destitute drifter, escorting Princess Shirley through treacherous outer-rim border sectors toward the safety of the Guardian Alliance.
Along their trek, Robin's power-hungry daughter abandons them for a rival warlord, leaving Caesar and Shirley cornered by elite bounty hunters. Shedding his vagrant guise, the cybernetic champion unleashes his devastating heavy weaponry, obliterating enemy fleets and assassinating the syndicate mastermind. Choosing freedom over royal politics, Shirley surrenders her crown to explore the outer cosmos at Caesar's side.
