Martian Successor Nadesico - The Motion Picture: Prince of Darkness (1998)

Two years after the events of "Kidô senkan Nadeshiko" (1996), Akito and Yurika are missing and presumed dead, the former foes of the Great War are allies, and the 14-year-old genetically-engineered wunderkind Ruri Hoshino is now captain of the new Battleship Nadesico. When a Martian separatist group initiates a well-planned, well-executed and most of all successful military action, the combined Earth-Jovian government and military are paralyzed by confusion and internal bickering. It is up to Ruri to reassemble the mostly-retired crew of the original Nadesico to take on an unsanctioned mission to bring a halt to the Martian Successors, free their stranglehold on Boson jump transportation, and discover the fate of Akito and Yurika.
