I don't think her breast size was ridiculous (at least, not going by the image of her in the characters area of the manual) but I do agree that her outfit was ridiculous considering what she was getting up to in battles. But then, most Final Fantasy outfits have been ridiculous. But yeah, I know a few girls who have breasts about that size. It's more common over here than in America, though, I understand. Despite me thinking the breasts weren't unrealistic, I do agree that they were fanservice, though. And I don't mind.
