You've always been the bully at school, and Jason has been your favorite target. You never gave much thought to the pain and humiliation you were causing him, but that all changes one day when Jason finally snaps. He transforms you into a little girl, no more than five years old. You're terrified and confused, and Jason says that he'll only turn you back to normal if you agree to be his little sister for a whole year. So, reluctantly, you agree to be Jason's little sister.
