Your name is Shina Hosakay you are an orphan, have been since you was 5 going on 6 years old. You was made an orphan by someone killing your parents and brother, you used to live in a village called the Hidden Sun Village, i say used to, as after your family was killed your grandfather the Sokage suggested it would be best if you left, you never liked your grandfather he always seemed obsessed with power so since you were the heir to the Kage thrown , it didn’t surprise you that he wanted you gone! You had always expected he was behind the murder of your parents but thought it was stupid to think he would kill his own daughter...was it!The only way you could find your answers was to find the man who killed your parents.
So back to you, now you are very special indeed, first of all you are rare, you was born with the 11th tailed beast, now it doesn’t actually have 11 tails and it is older than all of the tailed beasts put together also the fact that i saw you was born with the beast must interest you, now usually jinchuriki's have the beast sealed within them but you was a special type of jinchuriki now the beast was called Onca, and apart from the fact that she was extremely strong, stronger than all of the tailed demons put together, but she also had 4 different forms each with different strength and chakra abilities. Onca was sealed away in 4 different people before you, no one knew quite how it worked but she was bound to you from birth. (The rest is similar to Naruto Uzumaki and the other jinchuriki's, y'kno when you get angry and stuff, only difference your eyes go blue instead of red, and you actually grow whiskers instead of Naruto's already there ones enhancing...you get the point).
As well as all the power the demon gave you when you used it, you were rather good at copying people jutsu's because you have the rare ability to use all chakra natures, wind, water, lightning and earth!
Anyway, Onca was one bad pointer in your life you constantly thought that you life sucked, it was even worse when you got involved with Orochimaru!
*Past*
You was 6 years old, training in the woods you were very strong for your age but not that strong, well anyway, you was enjoying your training session, when a voice disrupted your training, "Very nice Shina!""Huh!!" you turned to face the owner of the voice, "W-Who are you? H-How do you know my name!?" you asked whilst partly scared and out of breath."My name is Orochimaru," he began and smirked, "And i know all about you my dear," you looked at him wide eyed, you yourself did know about what was inside you but you was only blurred on the details, so you narrowed your eyes as Orochimaru continued, "Your name is Shina Hosakay, the granddaughter of Sabau Hosakay, and jinchuriki of the 11th tailed beast, and i also know the reason why you are here all by yourself is because your parents have been killed and you are all alone!"You stood there frozen shocked at how much he knew and you jumped to the obvious conclusion,"Did you kill my parents!" you yelled, Orochimaru smirked, "Oh no my dear, but i know who did?""Who?" you stood there not letting your guard down, your brother was training with the leaf and sand villages so therefore he taught you everything he learnt, and so the one thing you knew was never to let your guard down,"A man called Lycan Tabuto, hired by...Sabau Hosakay!" he replied, your eyes widened and your eyes filled with tears,"It cant be true....." you whimpered,"Well thats for you to find out, now the main reason why i am here is to offer you the strength to get your revenge on your family's murderer!" you backed away,"What!?" you yelled,"Join me and i will give you...train you and give you the power to defeat anyone in your path!" as he spoke you were beginning to get somewhat scared i mean you were a child, and you knew you had some strength but to be wanted by some old guy!"Back off grandpa! If i wanna get strong i'll do it my own way!" you yelled at him, causing him to smirk, "Big mouth for a young child, yes you will be a handful," as he said this he began to get walk to you,"I cant be handful if i don't join you...you weirdo!" you screamed and backed away but before you knew it Orochimaru was up in front of you, your eyes widened,"You will come to me eventually!" he said then he looked as if he was going to bite you, so you punched him in the gut and jumped back,"What the hell is your problem!?" you shouted, he smirked, "For a brat your pretty strong! But not strong enough!" he said, then ran at you, you fought with him for as long as you could but you were young and already tired so you were pushed you the ground easily when he kicked you, you were panting and breathing heavily you felt faint, when suddenly you saw Orochimaru's head extend from his shoulder the neck stretched like an elastic band."What are you!?" you gasped, then your eyes went wide as he smirked the bit you neck - just on you shoulder, you then collapsed.
You awoke hours later in the company of an old man who rescued you, to find a curse mark on your neck, the old man's name was Tuskui Mikoshi, he became a great help in information about Orochimaru he knew a lot and helped with your training until you left to travel and train with many different people you stopped at many different villages, you where heading for the Hidden Leaf Village, and nothing was going to stop you getting there!
