Gintama

Aliens known as the Amanto have invaded Earth and taken over feudal Japan.

In this strange new era, a man named Gintoki Sakata with the heart of a samurai, and the odd company he keeps, have found a way to stay self-employed. They take on odd jobs, everything from finding lost kittens to saving the world.

But the jobs rarely go as planned and never pay enough to cover their pain—or their rent.
