Twelve years before the events at the focus of the series, the nine-tailed demon fox attacked Konohagakure. Powerful enough to raise tsunamis and flatten mountains with a swish of one of its tails, it raised chaos and slaughtered many people, until the leader of the Leaf Village ? the Fourth Hokage ? sacrificed his own life to seal the demon inside his newborn son, Naruto Uzumaki. The Fourth Hokage, who was celebrated as a hero for sealing the demon fox away, wanted Naruto to be respected in a similar light by being the containment vessel for the demon fox. The Leaf Village, however, shunned him, regarding Naruto as if he were the demon fox itself and mistreated him throughout most of his childhood. A decree made by the Third Hokage forbade anyone to discuss or mention the attack of the demon fox to anyone, even their own children. However, this did not stop them from treating him like an outcast and as a result he grew up an orphan without friends, family, or acknowledgment. He could not force people to befriend him, so he sought acknowledgment and attention the only way he knew ? through pranks and mischief. However, that soon changed after Naruto graduated from the Ninja Academy by using his Multiple Shadow Clone Technique, a technique from a forbidden scroll that he was tricked into stealing, to save his teacher, Iruka Umino, from the renegade ninja Mizuki. That encounter gave Naruto two insights: that he was the container of the demon fox, and that there was someone besides the Third Hokage who actually cared for and acknowledged him. His graduation from the academy opened a gateway to the events and people that would change and define his world, including his way of the ninja for the rest of his life.[4] The main story follows Naruto and his friends` personal growth and development as ninja, and emphasizes their interactions with each other and the influence of their backgrounds on their personalities. Naruto finds two friends and comrades in Sasuke Uchiha and Sakura Haruno, two fellow young ninja who are assigned with him to form a three-person team under an experienced sensei named Kakashi Hatake. Naruto also confides in other characters that he meets throughout the series as well. They learn new abilities, get to know each other and other villagers better, and experience a coming-of-age journey as Naruto dreams of becoming the Hokage of the Leaf Village. Throughout all of the Naruto plot, strong emphasis on character development changes the plot, with very few things happening because of chance. At first, emphasis is placed on Naruto, Sasuke, and Sakura, who are the members of Team 7. However, other characters are developed, such as Kakashi, Tsunade, and Jiraiya, as well as Naruto`s peers in the other teams and villages. Several major villains come into play as well, the first being Zabuza Momochi, a missing-nin from Kirigakure, and his partner, Haku. Later, in the Chunin Exams arc, Orochimaru is introduced as an S-Class missing-nin at the top of Konoha`s most wanted list. Later still, a mysterious organization called Akatsuki begins to pursue Naruto for the nine-tailed demon fox inside him.
