Gintama Season 4

After joining the resistance against the shogunate, Gintoki and his group go into hiding with Katsura and his Joui rebels. Shortly thereafter, Nobume Imai and two members of the Kiheitai approach the Yorozuya and explain that the Harusame Pirates have turned against Seventh Division captain Kamui and his former ally Takasugi. The Kiheitai entrusts Gintoki with a mission: to find Takasugi, who has been missing since his ship was attacked during a Harusame ambush. Nobume also reveals shocking information about the Tendoushuu, a secret organization that controls numerous factions, and its leader, Utsuro, a mysterious figure with a striking resemblance to Gintoki's former master. Aboard Sakamoto's spaceship, the Yorozuya and Katsura depart for Rakuyou, Kagura's homeworld, where the various factions have gathered and tensions are palpable. Deep-seated grudges, internal political strife, and the Tendoushuu's sinister master plan finally culminate in a massive and decisive battle at Rakuyou.
