Naruto's Vow

is episode 242 of the Naruto: Shippūden anime.

Summary
While on his way to meet messengers from Iwagakure, Chōjūrō decided to go on ahead by himself due to the lack of wind making his ship sail slowly. Kurotsuchi and Akatsuchi were sent by the Tsuchikage on an island in the Land of Water, suddenly a team from Kirigakure ambushes them, injuring Akatsuchi in the process. Naruto and Chōjūrō stopped them. Kurotsuchi argues with Chōjūro to tend Akatsuchi's injuries, which he answered that there are no hospital in the island. Kurotsuchi asks why they attacked them, which Chōjūrō replied that there are shinobi who opposed the Allied Shinobi Forces like the jōnin Ganryū, the sole survivor of the Tragedy of Yosuga Pass. Hearing that Ganryū wants to have revenge in them, Kurotsuchi heads out to kill him, but Naruto interfered. Naruto also stopped Ganryū from having his revenge, stating that it will just create a cycle of hatred. As Kurotsuchi attempts to slash Ganryū using her sword, Naruto became a body shield. Chōjūro suddenly arrived, telling Ganryū to surrender, which he gave himself without hesitation. He also told him that the two Iwa-nin as messenger by the Third Tsuchikage to apologise regarding the incident ten years ago, and return personal belongings recovered from the Kiri ninja who died because of it.
