Aliens known as the Amanto have invaded Earth and taken over feudal Japan. The government has been overpowered and humanity turned into slaves. In this strange new era, a man named Gintoki Sakata with the heart of a samurai, and the odd but endearing company he keeps, have found a way to stay self-employed. They take on all sorts of odd jobs, everything from finding lost kittens to saving the world. Naturally, these odd jobs aren’t always simple, as they frequently have run-ins with police, rebels, and assassins. The jobs rarely go as planned and almost never pay enough to cover their pain—or their rent. But things get really serious when the shogun’s life is in peril, and Gintoki’s past comes back to haunt him. It’s the battle of a lifetime as everyone teams up for a task unlike any other!
