SVTFOE: Gender Bend AU

On Mewni, you're a princess, or you're worthless. Makes one wonder what it's like to be a prince. My name is Comet Butterfly, and I am the prince of Mewni. My parents have never cared about me. it's always been about my little sister, Star. She's fourteen, and I'm fifteen. She's supposed to get that accursed wand that is RIGHTFULLY MINE! It won't matter though, because, with help from my demon girlfriend Tiffany, I'm getting the Hell outta here, and I'm going where the two won't find me. They can't ignore me I they don't know where I am! Today's the day, I flee from Mewni...

Notes: Yes Star and genderbent Star (Comet) both exist, and I'm not changing Moon or River for plot purposes.
