Claire Novak: Female Hunter

Claire is a girl who was thrown into the world of supernatural beings from a young age when her father was possessed by the angel Castiel. Now she is 20 years old, and hunting on her own, but what will happen when the Winchesters, who see Claire like a little sister who they need to protect, find out about this? Will they help her out? Or try to keep her away from hunting at all costs?
