I'm Gaara's Twin, WAIT HOW IS THAT POSSIBLE!?

Yo, my name's Suki, I don't have a last name. Here's the crazy thing. I have a voice that talks to me in my head, he says his name is Shukaku, like that Gaara guy in Naruto. He's my favorite character out of them all. But if I have Shukaku in me, then what does that mean? I mean is it possible? Anyways, I remember going to bed and the next thing I know, I'm waking up and I see The sand siblings in front of me. AND I FIND OUT THAT I AM GAARA'S TWIN SISTER!! WOAH!
