Seeing Tobi’s Sharingan, Sasuke’s left eye takes the form of Itachi’s Mangekyo Sharingan and summons Amaterasu. Tobi, engulfed in flames, drops his mask and retreats into the shadows. Sasuke doesn’t understand what happened. A few seconds later, Tobi returns and says that Itachi put Amaterasu in Sasuke’s eye before he died. Sasuke remembers the moment Itachi engaged his forehead and asks why he did it. Tobi says it was done for protection. Sasuke gets angry when he hears about it, to which Toby says that there are many things Sasuke doesn’t know about Itachi. Tobi, introducing himself as Madara Uchiha, offers to listen to the story of Itachi’s life. Sasuke refuses to listen, but Tobi stubbornly insists, claiming that it is his duty to know the truth.
