The Forbidden Visual Jutsu

is episode 210 of the Naruto: Shippūden anime.

Summary
Danzō figures out Itachi was an illusion of Sasuke's Tsukuyomi. An enraged Sasuke completes his Susanoo and fires an arrow at Danzō, but Danzō deflects the arrow using his Wood Release. Madara realises that Danzō collaborated with Orochimaru in order for Danzō to use Izanagi. Danzō's attacks do little to none damage against Sasuke's Susanoo. Danzō summons his Baku to help him out, but it is defeated by Sasuke's fireball. As the battle drags on Sasuke forms a chakra blade while Danzō creates a wind weapon with his kunai. They then strike one another simultaneously.
