The Eve of the Five Kage Summit…!! (五影会談前夜…!!, Gokage Kaidan Zenya…!!) is chapter 453 of the Naruto manga.
While Taka is heading to Konoha they are met by Tobi. Tobi informs them that they are wasting their time since Konoha has already been destroyed. What's more, they failed to capture the Eight-Tails and thus are still indebted to Akatsuki. To reach a compromise, Tobi sends them to the approaching Kage Summit so that Sasuke can kill Danzō, the new Hokage and a conspirator in the Uchiha clan's assassination. In Konoha, Sakura is brought to tears by Team Samui's requests to give them information that will be used to kill Sasuke. Naruto offers to tell them what they need so that Sakura doesn't need to, adding that they can still save Killer B if they act soon.
