A young boy named Jiro finds his mother and sister murdered in his home. Falsely accused of the crime, he flees from his village and meets a priest named Tenkai, who has him kill a rogue ninja named Tarouza. After fulfilling that task, Jiro undergoes training to become a master assassin. Many years later, Jiro finds out that he was an orphan and his real father was Tarouza, who had worked for Tenkai until he aborted his mission when he fell in love with an Ainu woman. The young ninja discovers that the Shogunate was to retrieve the lost treasure of Captain Kidd and use it to once again isolate Japan from the rest of the world. Using the clues that Tarouza had kept secret, Jiro—along with the female ninja Oyuki and a slave named Sam—travels to Russia and America to search for the treasure in hopes of using it to extract revenge from Tenkai.

Kou Kitamura and Aoba Tsukishima are often at odds—even though their families happen to be close friends and business partners. Although the only child of a sports shop owner, Kou has never been interested in playing baseball. Despite this, he possesses an impressive batting ability honed by frequent visits to the local baseball batting center run by the Tsukushima family. On the other hand, Aoba loves to play baseball and is a star player with exceptional pitching form. However, these two seemingly complete opposites share something very important to them—Wakaba Tsukishima, Aoba's older sister and Kou's destined sweetheart. Admired by the quarrelsome duo, Wakaba often finds herself the catalyst to their never-ending rivalry. But whether or not they realize that they have more in common than either would care to admit, only time will tell. The game of baseball may just be what the pair needs to ultimately overcome their own personal struggles. [Written by MAL Rewrite]

Gintoki, Takasugi and Katsura fight past the Tendoushuu forces, who have taken over the Terminal. The mothership at the top of the terminal is absorbing large amounts of Altana and channeling it into the body of the child Shouyou in order to resurrect him and obtain true immortality. As the group is attacked, they split up into two, with Katsura holding on to Shouyou's heart. Katsura and Hitsugi engage in a fierce battle, and the latter eventually stabs and destroys the heart, revealing that he had no intention of reviving the child; he only wanted to free Utsuro from the curse of immortality. Without the heart, Shouyou would only be able to regenerate and maintain his body temporarily. In the terminal, the Shinsengumi, Hyakka, Oniwabanshu and the rest of the Kabukicho residents fight the rest of the Tendoushuu army, while Matsudaira shoots down the ships outside. Then Gintoki reunites with Kagura and Shinpachi and they rush towars the top of the terminal.In the meantime, Takasugi reaches the Tendoushuu's ship to find that Shouyou has been revived and killed off the rest of the Tendoushuu. Shouyou's only wish is to put an end to himself and Utsuro. Takasugi begs Shouyou to return to Shoka Sonjuku with him. Shouyou apologizes for not being able to save his disciples, the ones that he truly wanted to protect. As he approaches Takasugi, the latter stabs him, revealing that Utsuro's blood has taken over his body as well. This causes a large explosion at the top of the Terminal. Gintoki is separated from the others and faces off Utsuro, now manifesting in Takasugi's body, Utsuro comes to a realisation that Takasugi did not stab Utsuro earlier. Instead, supported by Oboro whose blood also runs through his body, Takasugi stabbed himself. The body that Utsuro saw lying on the ground was himself. Gintoki and Utsuro fight each other.
