Naruto Volume 32: End of Tears

Sasuke once looked up to his older brother Itachi. Now, he'll do anything to destroy him. In the Final Valley, Naruto must do his best to turn Sasuke from the path of revenge. But Sasuke's resolve may prove too much for even the ninja who holds within him the power of the Nine-Tailed Fox. Naruto has a promise to keep, and he won't ever let go of the ties of friendship--but his friend is ready to do everything in his power to sever those ties forever.
