Susanoo…!!

Summary
Itachi reveals Susanoo, the last of the techniques granted to him by his Mangekyō Sharingan. It surrounds Itachi and protects him from all damage. Seeing this, Orochimaru offers to help Sasuke defeat Itachi. Orochimaru's Eight Branches Technique erupts from Sasuke's body and attacks Itachi. Susanoo cuts off the serpent's heads, prompting Orochimaru to reveal himself. He thanks Itachi for pushing Sasuke to his limits and thus allowing him to escape. He prepares to take Sasuke's body, but is struck by Susanoo. As a special property of Susanoo's sword, Orochimaru is sealed away, removing him and his cursed seal from Sasuke's body.
