A ban on carrying swords in public hasn't stopped Gintoki Sakata from calling himself a samurai—or carrying a wooden sword. The eccentric, silver-haired founder of Yorozuya makes his living taking odd jobs in Edo, helping people through methods that rarely turn out to be straightforward.
Edo's samurai have lost their former standing since feudal Japan surrendered to the powerful aliens called the Amanto. The shogunate now serves as a puppet government, leaving little room for the ambitions that once drew samurai to the city.
Gintoki has an unusual team at his side: Shinpachi Shimura, a bespectacled boy supposedly studying the samurai way; Kagura, a tomboy with extraordinary strength and a bottomless appetite; and Sadaharu, their enormous pet dog with a fondness for biting heads. Their work brings them into contact with alien royalty and local gangs alike.
