high_seas has a wee Naruto cast right now (just this buttface and Itachi) and I would love a Sakura! Premise is that everyone has been pulled to this world to be pirates in search of a magical jewel. The overall plot involves the jewel and the in-world Navy, which isn't fond of pirates and assumes anyone new in the world is one, as well as monthly events and curses. Mods are very open to player plot in my experience! :D

AC is every two months; one network post plus two other posts (more info here).
