A series of comedic YouTube shorts with Tsunomaki Watame.

Edo is a city that was home to the vigor and ambition of samurai across the country. However, following feudal Japan's surrender to powerful aliens known as the Amanto, those aspirations now seem unachievable. With the once-influential shogunate rebuilt as a puppet government, a new law is passed that promptly prohibits all swords in public. Enter Gintoki Sakata, an eccentric silver-haired man who always carries around a wooden sword and maintains his stature as a samurai despite the ban. As the founder of Yorozuya, a small business for odd jobs, Gintoki often embarks on endeavors to help other people—though usually in rather strange and unforeseen ways. Assisted by Shinpachi Shimura, a boy with glasses supposedly learning the way of the samurai; Kagura, a tomboyish girl with superhuman strength and an endless appetite; and Sadaharu, their giant pet dog who loves biting on people's heads, the Yorozuya encounter anything from alien royalty to scuffles with local gangs in the ever-changing world of Edo.

Demonic Vice-Commander of the Shinsengumi, Toushirou Hijikata, acquires a cursed sword—one which completely rewrites his personality, morphing him from a hard-boiled, no-nonsense cop into a hopeless otaku. As he struggles to break the curse, an ambitious new member of the police force, Itou Kamotarou, seizes the opportunity to depose Hijikata in his bid for power within the organization. However, Itou's scheme is revealed to be more devious than anyone imagined, and the very existence of the Shinsengumi is thrown into peril. In another time and place, the Yorozuya squad is suddenly greeted by a potential new recruit. Before them is a mysterious young woman named Pirako Doromizu who hides a penchant for extreme violence behind her smiling, enthusiastic exterior. However, unbeknownst to Gintoki and the others, Pirako has strong ties to one of the ruling figures of the Kabuki district of Edo, and her arrival sets off a chain reaction that throws the inhabitants of the district into a civil war.

As the war temporarily calms down and Edo rebuilds, Gintoki finds Shinpachi—who is still unaware of his return—on a bridge. However, as a fight quickly breaks out between the Yorozuya and the Tenshouin Naraku, suspicion grows, forcing Gintoki to use what is nearest—a loincloth—to mask his identity. Saved for the time being, Gintoki enters the Yorozuya office, but unbeknownst to him, someone else is already waiting there... Meanwhile, Kondou departs Earth to marry Princess Bubbles in an attempt to improve diplomatic relations. After boarding the Gorilla Amanto mother ship, he realizes that he doesn't speak their language. Confused, Kondou tries conversing with them, only to inadvertently gain their support. However, someone associated with the princess crashes the ongoing ceremony. Will the wedding continue, or has Kondou just been saved from becoming the next Gorilla Prince?
