Gin Tama, Vol. 3 by Hideaki Sorachi

[Viz] 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. Gin's "to do" list for this volume: 1. Pick a fight with those Shinsengumi losers 2. Throw out my old SHONEN JUMP magazines 3. Save Shinpachi and Kagara AGAIN 4. Take Kagura's so-called dog for a walk 5. Protect the environment
