Gintama Vol.23 (Ed. em Inglês)

It's samurai vs. aliens!

The samurai didn't stand a chance. First, the aliens invaded Japan. Next, they took all the jobs. And then they confiscated everyone's swords. So what does a hotheaded former samurai like Gintoki "Gin" Sakata do to make ends meet? Take any odd job that comes his way, even if it means losing his dignity.
