"Itachi and Sasuke" (イタチとサスケ, Itachi to Sasuke) is chapter 367 of the original Naruto manga.
Itachi tries to make casual conversation with Sasuke, who instead attacks him. Impressed by how much stronger he has become, Itachi makes arrangements for them to meet in person before his clone disperses. In Konoha, Jiraiya sets out for Amegakure to investigate Akatsuki. Tsunade warns him to be careful and asks to request her help if things get difficult. Jiraiya points out that, as Hokage, Konoha needs her, but she responds that Naruto will inevitably replace her in the position. They discuss Naruto's similarities to his parents, Kushina Uzumaki and Minato Namikaze. Having taught Minato, Jiraiya says that he feels like Naruto is his grandson. He warns Tsunade about Danzō before leaving. He arrives in Amegakure but is immediately detected by Pain.
