User blog comment:FoolishMortalFOOL/Yohohoho! Pirates! Are you powerful enough to become a Shichibukai and.....YONKOU?!!!!/@comment-4011052-20110606144414/@comment-3507136-20110606192604

How about this dude?

The Fleet Admiral chooses the 7 Shikibukai to keep the pirates pages in order (Other than it being a gift) and The Commander thingy that Roranoa Zoro is (I forgot sorry :P) chooses the 4 Yonkou to oversee the pirate crews, pirates, islands, and keep them all in order in fill them in if their is something wrong (Still being a reward)

And I Personally think it should be one reward per user E.g. 1 user can be a marine and shikibukai but not 2 shikibukai or two yonkou otherwise someone may end up getting all the rewards and noone would get a chance .. .
