When you were born you were born with small and short nine tails, the doctors were baffled by this and thought it was some sort of defect but your parents didn't really care and loved you, however, society didn't so you were always called a freak and so was your sister who only had one. you and her would go to the woods all the time and there you learned to control the elements. (Btw your tails gores bigger and longer as you grown)
