Naruto's Vow

is episode 242 of the Naruto: Shippūden anime.

Summary
While on his way to meet messengers from Iwagakure, Chōjūrō decides to go on ahead by himself, due to the slow progress in travelling. Naruto and his group stop at one of the smaller islands off the coast of the Land of Water for restocking before going straight to the Land of Lightning. Naruto sets off to eat. Akatsuchi is sent by the Tsuchikage to the same isolated island in the Land of Water to rendezvous with Chōjūrō, and Kurotsuchi tags along. As they await, they're attacked by a group of Kirigakure ninja, led by Ganryū. Battle ensues and Akatsuchi is injured. Naruto and Chōjūrō interfere and stop the battle. Chōjūrō demands Ganryū and his team to withdraw, stating that they are violating the Mizukage's will. The team leaves, and Kurotsuchi argues with Chōjūro to tend Akatsuchi's injuries, who says they need to wait for a medical-nin. Chōjūrō explains those were ninja who oppose the Allied Shinobi Forces, Ganryū being the sole survivor of the Tragedy of Yosuga Pass. Kurotsuchi heads out to kill Ganryū before he can kill her. Naruto however, stops Kurotsuchi from fatally injuring Ganryū, telling Ganryū that it will just create a cycle of hatred. Kurotsuchi attempts to slash Ganryū using her sword, but Naruto blocks it with his body. Ganryū agrees to let Naruto fulfil the peace. Chōjūro arrives with other Kiri ninja, telling Ganryū to surrender, which he does. Chōjūro informs him that the Iwa messenger was sent by the Tsuchikage himself, to formally apologise for the Tragedy of Yogusa Pass, and return a personal belonging of one of Ganryū's team-mates who was killed in it. Chōjūro tells the others that Ganryū won't be sentenced for execution. Akatsuchi then tells Kurotsuchi that Kiri will just owe Iwa a favour in the future to come, delighted that the Iwa-Kiri grudge has come to an end. Naruto leaves in a hurry, without introducing himself to the others. Once arriving with Yamato and the others, they await for a new ship to take them to the island in the Land of Lightning.

Trivia

 * Team Ganryū's flak jackets are erroneously depicted like Iwagakure flak jackets with the exception of their colour.
 * Ganryū also wears a white forehead protector cloth; usually only seen on Kumogakure shinobi.
