I Hate My Roommates!

Dio, Kars, Kira and Doppio/Diavolo are sent to a mysterious room after their respective deaths, and after a fateful meeting with an angel, they are tasked with travelling to worlds not their own to save. Can the four withstand this monumental mission of epic proportions, and more importantly, withstand each other? (Comedy/friendship with a bit of action on the side, maybe 50%)
