Gutsy Master and Student: The Training

is episode 187 of the Naruto: Shippūden anime.

Summary
Naruto and Jiraiya have left Konoha to begin their three year journey. They are talking about, Naruto's overcoming Sasuke's Sharingan and the eye's Genjutsu ability. Jiraiya summons Gamariki to place Naruto inside Genjutsu Kiss. Naruto is sad to disrupt his own flow of chakra, but instead, he did the other way creating a wave of chakra around him thus hitting Gamariki. They are coming to Village hidden in Genjutsu Trees to train there, because it has natural genjutsu affinity. Villagers act weirdly because they are in captivity. Kandachi has come there to hide from Amegakure Pursuit.
