You are a normal young girl, but you live in a terrible family, your parents always abuse you, and your older siblings always bullying you

One night, you are asleep and you feel your back feeling a little pain and it got worst, you start to tear up from the pain and your back Spain comes out and turns into a muscular body and a dragon head

Skull king: Greetings young one.. He has his muscular arms crossed and you see he's attached to your back ribs
