"Gutsy Master and Student: The Training" (ド根性師弟修業編, Dokonjō Shitei Shugyōhen) is episode 187 of the Naruto: Shippūden anime.
While recovering from his injuries after having foughtSasuke, Naruto is visited by Jiraiya, who tells him that as soon as he is discharged from the hospital, they would be leaving Konoha for three years in order to train. Jiraiya advises that Naruto train solely to fight off the Akatsuki and that he would be a fool to chase Sasuke, but Naruto declares proudly that he is a fool. As Naruto recovers, the two set off on their journey.
Elsewhere, Jiraiya attempts to teach Naruto how to break out of a genjutsu illusion, since Sasuke would most likely be learning how to master genjutsu using his Sharingan. As Naruto practises all night, Jiraiya recalls how he told Naruto that he bore a striking resemblance to the Fourth Hokage and thinks back upon Naruto's parents, Minato and Kushina. The next day, Jiraiya summonsGamariki to inflict his Genjutsu Kiss on Naruto, advising Naruto to rotate his chakra from within in order to disturb his chakra flow, thus breaking out of the genjutsu. Instead, Naruto rotates his chakra externally and hits Gamariki.
In order to hone Naruto's skills, Jiraiya and Naruto head to the Genjutsu Tree Village, where the trees give off a magnetic field that induces genjutsu. However, they discover that the entire village has been taken over by Kandachi, who is keeping the women and children hostage after killing Sukune, the village's former leader. In order to defeat Kandachi, Naruto transforms into Tanishi, the child who had notified them of the village's crisis, and ties up Jiraiya, pretending that he had caught Jiraiya as his prisoner. The two are then escorted to the lake, where Kandachi resides and where the prisoners are held.
When Naruto looks at Hokage Rock before leaving with Jiraiya, Tsunade's face is next to Minato's, even though it wasn't there when they left at the end of Part I. In fact, when Naruto returned to Konoha, he claimed that the only thing different about the village was that Tsunade's face was now engraved on the rock.
