Don't Talk about Itachi (イタチを語るな, Itachi o Kataruna) is chapter 477 of the Naruto manga.
Sasuke tries attacking Danzō with Susanoo again. Danzō once again appears to die, only to appear elsewhere unharmed. Even Amaterasu does not seem to affect him. Madara and Karin study his actions to try and determine what he is doing, eventually noticing that the Sharingan eyes on Danzō's arms steadily close. Danzō congratulates Sasuke for, with his Mangekyō Sharingan abilities, earning the status as Itachi's brother. Sasuke is enraged by Danzō's mentioning Itachi and only becomes more determined to kill him. After surviving additional attacks, Danzō is faced by Itachi.
