You always lived with your grandma. Well, not always, but you didn't remember that.
Your parents are Nagato Uzumaki and Konan of the Akatsuki and you have a - 4 years older than you - brother named Akashi Uzumaki.
You lived with your family happy till you were 3 years old. At that age, your grandma took you away from your parents, because she didn't trust them with you.
Although, your parents and brother never stopped trying to get you back. But every time they tried, your grandma hid you somewhere.
You and your brother are looking really similar. Almost like twins, but he is older and a male. He, also, has a burn mark starting from the right side of his forehead and expands till the end of his right cheek - created by your grandma when she tried to keep him away from you.
Today, you were 12 years old and just came home from your first day in the ninja academy of Konoha.
