Sasuke, the Mentor

Sasuke, the Mentor is the fourteenth episode of Part IV.

Synopsis
Naruto is shown shocked from Sasuke's decision to go with Riyan. Ryun too voices his protest, but Sasuke refuses to hear it. He claims that now that he knows others of his clan have survived, it was time to be with them, no matter the cost. He breaks his ties with Koukon and both Sasuke and Riyan use Body Flicker Technique to escape; leaving Naruto and Ryun stunned.

Naruto tells Ryun that it's time to take their Uchiha friends back for good. He briefly explains his and Sasuke's relationship and Ryun explains his own. Naruto then says that it's time to gather Riyan's friends and Sasuke's friends and go after them.

Meanwhile, at the Uchiha hideout in the Land of Mountains, Riyan explains to Sasuke about Ibitsu Uchiha and about Tsukiakari. He then asks Sasuke to teach him the stuff he learned from Orochimaru and Madara, as he needed to approve. Sasuke then agrees and the two go off to train.
