Naruto Uzumaki is boy that lost his parents in an attack of nine tails fox. The name of his father is Minato and the name of his mother is Kushina. His dad it was the fourth hokage (hokage was a kind of king in the village who Naruto lives). This fact happened when he was born. to save him , and to protect your village, your parents put half of the soul of nine tails fox into naruto, after Minato sealed a part of the soul of the nine tails fox, the other party tried to kill Naruto, but in this time Minato and Kushina they have sacrificed to protect him. And when minato I was almost dying he sealed the other part of the soul inside him.
Because of that, when Naruto was a kid, people hated him ,then he did ugly things to draw attention
