Naruto  

There was once a Nine-Tailed Demon Fox who attacked the Hidden Leaf Village of the ninjas. A swipe from one of its nine tails could cause earthquakes and crumble mountains. All the ninjas in the village tried to fight it in vain, until the Fourth Hokage sacrificed his own life to seal the Demon Fox away...within the navel of a newborn baby boy. That boy's name: Naruto Uzumaki.

It is now twelve years later, and Naruto has grown up to be a very mischievous young boy, painting graffiti on the monuments and pulling pranks on everyone. He seems to enjoy bumming around, and is not taking his ninja apprenticeship too seriously. In fact, his teacher, Iruka tells him that he is the only one in the class who hasn't yet passed the final apprenticeship test, and Naruto has already failed the test three times! But when a devious plan by an ambitious "Chuunin" (middle-level ninja) places Iruka-sensei's life in danger, Naruto's determination manifests itself and he saves his teacher. Naruto passes, and he now begins his journey towards being a true ninja!
