Gintama Vol. 3

Written and illustrated by Hideaki Sorachi, Gintama takes place in an alternate timeline of the Edo era in which the Earth has been invaded by aliens known as the Amanto. Eccentric samurai Gintoki is just trying to get by in this new world where swords have been banned by operating an odd jobs business. Hilarity ensues.
