FemNaruto. The Strawhats knew that Luffy had an older brother, which was Ace. But at that time, they still didn't know about the existence of yet another brother or even Luffy's supposed older sister. His mysterious older sister who apparently could walk on water and make a bunch of copies of herself. AU. Slow build of future romance (Maybe).
