The White Demon on the Dungeon

While messing up on another job(again) Gintoki, Shinpachi and Kagura end up getting inside of a rocket and sent to another world. A far away world, very small and not very know. A place where aliens haven't arrived yet and people go around doing magic and exploring dungeons. The Odd Jobs trio will do their best to make this place home until they get help and cause as much chaos.
