You are a kid from Konoha... but you were born with enormous powers... at your birth they were sealed away... but later the seal started losening a bit... so when you were only 4 it was decided by the hokage Kakashe Hatake, to bring you to an abandoned island... on that island was one village... the villagers were asked to take good care of you... on top of that a curse mark was placed on you, activated by a few handsigns... in case of an emergency where you lose control it could be used to get you in so much pain you would pass out... you knew about all of that... now you are 9 years old... you were on that island for 5 years now and everyone had always just looked at you from a distance with fear, hatred and distrust
