Itachi applies Susanoo, the last technique provided by his Mangekyo Sharingan. He surrounds Itachi and protects him from all damage. Watching this, Orochimaru offers to help Sasuke and defeat Itachi together. Orochimaru’s Eight Part Technique bursts out of Sasuke’s body and goes to attack Itachi. Susanoo cuts off the snake’s head, forcing Orochimaru to show up in person. Orochimaru thanks Itachi for bringing Sasuke to his breaking point, thereby giving him the opportunity to escape. He proceeds to seize Sasuke’s body, but is crushed by Susanoo. Using Susanoo’s special sword property, Orochimaru was sealed, thereby removing both him and the cursed seal from Sasuke’s body.
