Naruto Uzumaki is a young boy who has the Nine-Tailed Demon Fox sealed within him. Twelve years before the start of the series, the Nine-Tailed Demon Fox attacked the ninja village Konohagakure, slaughtering many people. In response, the leader of Konohagakure and its ninja military - the Fourth Hokage - sacrificed his life to seal the demon inside Naruto when he was a newborn. Konohagakure, however, regarded Naruto as if he were the demon fox itself and mistreated him throughout most of his childhood. The main story follows Naruto and his friends' personal growth. Naruto befriends two comrades, Sasuke Uchiha and Sakura Haruno, who are assigned with him to form a three-person team named Team 7 under an experienced sensei named Kakashi Hatake. Like all the ninja teams from every village, Team 7 is charged with completing missions requested by villagers, such as doing chores or being bodyguards. During the course of their missions, Naruto befriends other characters that he meets throughout the series. Team 7 learns new abilities, get to know each other, and experience a coming-of-age journey as Naruto dreams of becoming the Hokage of Konohagakure
