Gaara's Weakness

Gaara, the 'self-loving demon.' As a child in Suna, Gaara had met a girl, unlike any he'd met before: Strong, intellectual, skillful, and kind. She treated him, not as a monster, but as a person, even friend. Her looks balanced out her personality perfectly, in other words, she was beautiful. But can this mysterious girl survive the onslaught, that is the one-tailed demon, Shukaku, residing inside of Gaara? Even when she is battling her own demons?
Since she was born, she had a Tailed Beast sealed inside her, but this particular Tailed Beast was kept secret from everyone, in every village, except for the Kage's. Only few people in Suna knew about the eleven-tailed Hyena, Saori.
After birth since so few people knew about Saori, people believed her to be possessed by a demon of sand, much like Shukaku. If she moved her hand the slightest, tons upon tons of sand would crash down, evidently, she killed people, laughing all the while, because of Saori.
