Anyways, like with many characters first shown, the appearance can leave much up to the imagination. She seems like some calm and collected priestess, who didn't concern herself much in others affairs; simply because she had no interest. As an Uzumaki, we know she had a powerful life force; and was most likely skilled in fuuinjitsu. Obito, as Madara (he must have gave him this information) noted that she could sense others evil intentions. <------Why did kishi give us this bit of info? Who knows. It wasn't necessary at all. Unless, you know.
Having said that; I won't be surprised if there's a 'darker' side to her.
Not like I really had to explain why she's my top 3, but I thought I'd satisfy your curiosity. She seems like a very interesting character.
