The protagonists of the Naruto series are part of Team 7, a group of ninja affiliated with the village of Konohagakure. After Sasuke Uchiha's departure from Konohagakure at the end of Part I, the team disbands. During Part II, the team reforms with two new members, Sai, who occupies Sasuke's position, and Yamato, who acts as Kakashi's replacement when he is briefly incapacitated and later stays with the team when Kakashi returns.
