"Brother" (ブラザー, Burazā, Viz: Bro) is chapter 473 of the original Naruto manga.
Kisame is stopped from harming Killer B by the Fourth Raikage, drawn to the site of the water dome Kisame created earlier. Samehada restores B's chakra reserves, allowing him and the Raikage to team up and decapitate Kisame before he could use another technique. In the Land of Iron, Suigetsu and Jūgo are captured while Ao is elsewhere saved from death by the Fifth Mizukage. Fū Yamanaka, still in control of Ao's body, asks the Mizukage to help him remove the Byakugan's defences. This alerts her to Ao's predicament, forcing Fū to relinquish control. Meanwhile, Sai's ink clone approaches Naruto to tell him what Sakura could not.
