Two Konoha shinobi ask for his autograph, but he doesn't know how to respond. Three days later the Kage meet again to discuss how they should start pooling their resources. As the first matter of business, Naruto and Killer B are to be given constant protection. Tsunade objects since they would both be invaluable in the war with Akatsuki, but is forced to agree. Tsunade meets with A alone and asks him for a favour to let B teach Naruto how to control Nine-Tails. A says that the place where he is sending B and Naruto isn't just a hideout but a training ground.
