Description:During the Edo period, a mysterious man appeared in front of the samurai Katsura Kotaro. He held the demon sword "Red Sakura" and asked for a sword test. After this night, Katsura went missing. Katsura’s pet Elizabeth finds Kagura and Shinpachi in the House of All Things, and entrusts them to find the whereabouts of the owner. At the same time, Gintoki was also commissioned to find the whereabouts of the evil Red Sakura. The clues of the three people all point to an airship. Because it was far away from the police's jurisdiction, the evil forces in the airship covered the sky with one hand. There, Gintoki met Shinsuke Takasugi, his former comrade-in-arms, and Takasugi is now leading his ghost soldiers in an attempt to destroy Edo. On one side is a vicious terrorist, on the other side is the tyrannical and bloodthirsty Demon Sakura Kosakura. Can the seriously injured Gintoki escape safely and save Edo?
