Together with Hatred…!!

Summary
Both Naruto and Kisame are surprised to learn that Itachi and Sasuke are brothers. Years ago, after Itachi killed their family, Itachi told Sasuke that he had done so in order to test his abilities. Frightened that this could be his motivation, Sasuke tried to escape, only for Itachi to assure him he was too weak to kill. He instead encouraged Sasuke to grow strong enough to kill him and avenge their family. Intending to finally do so, Sasuke attacks Itachi with Chidori, but Itachi easily deflects it. Naruto begins gathering chakra so that he can help Sasuke when it is absorbed by Kisame. As Kisame moves to incapacitate him, Jiraiya appears and stops the attack.
