User blog comment:Ricizubi/It will be Shirahoshi, if this doesn't convince you even one bit that I give up/@comment-220.255.2.170-20111123161302

I'd rank her chance of joining a little higher than Jimbei after the recent chapter (647 to be exact). With Noah being as big as half of Fishman Island, it pretty much solve the size problem. FYI, San Juan Wolf was bigger than Oars & Little Oars Jr, but he still travel with BB by swimming around. Little Oars Jr had a ship big enough to fit him to be part of the Whitebeard crew. Whereas Shirahoshi is a mermaid, with her speed unsurpassed in the water. How is it impossible for her to travel with the crew if the "Continent Puller" and "Colossal Battleship" can? Next, if anything, there must be a reason for the prophecy that a man will guide Shirahoshi. Things like "the world will change when that time come" shows a lot of potential in her joining. In fact, she does have a reason to join. Because for years, the inhabitants of FI are fighting discrimination. Otohime's dream is to let the world know they're migrating. She wants the next generation to be under the real sun. And Noah, being half the size of FI, seems to me as a vessel for them to migrate. Hence the world shall be change with fishmen/mermen living on land without being discriminate against after Luffy finally become a Pirate King. Rather than them living underwater, struggling for or against the idea of Otohime's dream, they have a reason to follow a human whom is a hero (Luffy) to them, and don't mind being discriminate against because they're being used to it, so as to be under the real sun (1st part of the dream fulfill). The 2nd part of the dream to not be discriminate shall be fulfilled when Luffy became the Pirate King.
