In Gintoki's Japan, the arrival of the various space races known collectively as the Amanto ended the era of the samurai. The Amanto's highly advanced technology resulted in total conquest and a severe economic shift. Now, former samurai such as Gintoki scrape together whatever livelihood they can. Gintoki's profession of choice is that of a yorozuya: he'll complete any job for money. However, he’s unmotivated; and spending most of the day on the couch with the latest issue of Jump and a carton of Strawberry Milk is his preferred pastime. It turns out that his new unpaid employees, Shinpachi and Kagura, are going to interfere with his pastime even more than with his "work"! Of course, none of this means he has really given up on his samurai ideologies!
