"Madara Shows His True Worth!!" (マダラの真骨頂!!, Madara no Shinkotchō!!, Viz: Madara's True Worth!!) is chapter 475 of the original Naruto manga.
Summary[]
Gaara leaves the Konoha ninja. Before he goes he informs Kakashi that he and the other Kage will treat Kakashi as the new Hokage because of Danzō's actions, and while he repeats his personal recommendation for Naruto to give up on Sasuke, he also advises him to think and do what he thought was right for himself at least. Elsewhere, Danzō prepares for a battle with Tobi. While he does so, Fū Yamanaka and Torune Aburame fight Tobi, but are unable to land a blow. They try to hit him at a time when he is solid, but their attacks pass through him and they are ultimately warped away. With them gone, Tobi brings Sasuke and Karin to Danzō, offering to let Sasuke kill him. Danzō accepts the challenge, revealing an arm filled with Sharingan.
