Recounting the historic meeting of two of series creator Leiji Matsumoto's most striking heroines, Maetel and Emeraldas. Maetel is the black-clad traveling companion of the young hero, Tetsuro, while Emeraldas is a dashing pirate queen more familiar to fans of the Captain Harlock series. Here the two are seen in flashback, squaring off for a fencing match, Maetel in her long black coat, boots and fur cap and Emeraldas in her red jacket, red cloak and boots and white pants, both with long, flowing blond hair. The bulk of the story-line focuses on what happens when Emeraldas' ship forces the Galaxy Express to a stop on a remote planet and takes Maetel and Tetsuro prisoner. (Source: IMDb)

After joining the resistance against the bakufu, Gintoki and the gang are in hiding, along with Katsura and his Joui rebels. The Yorozuya is soon approached by Nobume Imai and two members of the Kiheitai, who explain that the Harusame pirates have turned against 7th Division Captain Kamui and their former ally Takasugi. The Kiheitai present Gintoki with a job: find Takasugi, who has been missing since his ship was ambushed in a Harusame raid. Nobume also makes a stunning revelation regarding the Tendoushuu, a secret organization pulling the strings of numerous factions, and their leader Utsuro, the shadowy figure with an uncanny resemblance to Gintoki's former teacher. Hitching a ride on Sakamoto's space ship, the Yorozuya and Katsura set out for Rakuyou, Kagura's home planet, where the various factions have gathered and tensions are brewing. Long-held grudges, political infighting, and the Tendoushuu's sinister overarching plan finally culminate into a massive, decisive battle on Rakuyou.

Based on the story by manga master Leiji Matsumoto (The Cockpit, Queen Emeraldas), the 55 minute featurette picks up one year after the events of Galaxy Express 999 in which a young boy named Tetsuro and his motherly companion Maetel worked to rid the universe on the Mechanized Empire who had taken over Earth.
