"The New Comrades…!!" (新しい仲間…!!, Atarashii Nakama…!!) is chapter 284 of the original Naruto manga.
Tsunade refuses the Konoha Council's instructions to keep Naruto under constant surveillance. Since Akatsuki will inevitably come after him, it is important that he go on missions in order to get strong enough to face them. They agree, but only if one of Danzō's men will be added to Team 7 as protection. She allows it, but selects Yamato a capable ninja from the ANBU as Kakashi's replacement and asks him to keep an eye on Danzō's choice. Meanwhile, Sai eludes Naruto and Team 10, promising to see them later. This proves to be when the new Team 7 first meets, and he wastes no time insulting his new team-mates, Naruto and Sakura.
