Here he states that it’s been one year since he had started working for Gintoki and has not once been paid. Shinpachi introduces us to the Land of the Samurai, and explains the events of the Amanto seizing Edo. All four then proceed to catch the cat, completely ignoring their surprised enemies. Sinpachi confirms that the cat is the missing Kuromi-chan that their client is looking for. A cat then passes between the two parties. When they are asked who they are, all three finally introduce themselves as the Yorozuya. They then proceed to run around town and “let” the men corner them. The men are right behind them, but just when they were about to attack Kagura appears while riding on Sadaharu and accidentally let’s the latter run into the men and send them flying. They then continue to run comically until they get to a modernly paved road, nearly hit by a flying car in the process. Once he is on the other side, he is met by a running Shinpachi who is also being chased by the men.

He jumps to the other side of a wall on the excuse that he wishes to watch something on TV by 4. The narrator introduces him as the hero of “this story”. The story starts with Gintoki being chased by men with swords, preferably samurai. Meanwhile, the Amanto Kariya and his men gather to plot the takeover of Edo city. After listening to Katoken’s endless tale of misfortune, the Odd Jobs trio feels obliged to help out. To regain something he has lost, Katoken needs 30 million ryo-a lot of money. One day he receives a visit from a client named Katoken. The samurai have lost their swords, status, and even their honor… In this city former samurai Gintoki Sakata runs the Odd Jobs business.

And now these arrogant aliens walk the streets of the city. The dream-filled Edo skies, upon which the samurai once gazed, are now filled with the ships of the Amanto, beings that suddenly invaded and rose to power. Long ago, this nation was known as the land of the samurai. 'Ever since the Sword Ban, nobody does this chanbara stuff anymore!'
