Cas' little sister (Dean Winchester)

Y/n

Hi my name is Y/n. I am an angel of the lord. I have lots of brothers and sisters, but I am close with one of brothers and that would be Castiel. He and I both have vessels that let us have their bodies. My brother is probably known for working with people named Dean and Sam Winchester, he tells me stories about them and what they do. Every time I hear my brother's stories, I want to go down to earth to meet them, but a long time ago, I met up with lucifer and let's just say, Castiel is very protective of me if I want to go down to Earth.
