In the far future where space travel has become the norm, Marika Kato is a high school girl living a rather ordinary life as a member of the space yacht club and a part-time job at a high-class retro café. One day, Marika learns of her recently deceased father, Gonzaemon, who is revealed to have been a Space Pirate who performed legal acts of piracy under the letter of marque. In order for her father's ship, the Bentenmaru, to continue legal operation, Marika, Gonzaemon's direct descendant, is chosen to become the ship's new captain, thus beginning her life as a Space Pirate.
