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. Kurotsuchi and Akatsuchi are sent by the Tsuchikage to an isolated island in the Land of Water to rendezvous with the already late Chōjūrō. As they await his arrival, they are approached by an ambushing group of Kirigakure ninja, led by a jōnin-level Kiri-nin named Ganryu. Battle ensues and Akatsuchi is injured in the process. However, Naruto Uzumaki and Chōjūrō arrive in time to stop the battle. Chōjūrō later demands Ganryū and his team to withdraw, stating that they are violating the Mizukage's will. As the team leaves, an irritated Kurotsuchi argues with Chōjūro to tend Akatsuchi's injuries, which he answers that there are no doctors on the island. As they wait for a Medical-nin, Kurotsuchi asks why they attacked them. Chōjūrō replies, saying that there are shinobi who oppose the Allied Shinobi Forces like Ganryū, a sole survivor of the Tragedy of Yosuga Pass. Hearing that Ganryū wants to have revenge for Iwa's past betrayal by killing them both, Kurotsuchi heads out to solve their situation once and for all by killing him. Naruto later interferes, stopping Kurotsuchi from killing one another. Naruto also stops 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 uses himself to block Ganryū from the incoming attack. After witnessing Naruto's act of kindness, Ganryū agrees to let Naruto fulfill the peace SChōjūro suddenly arrives, telling Ganryū to surrender, which he gave himself without hesitation. He then informs him that the two Iwa-nin messengers were sent by the Tsuchikage himself, in order to apologise regarding the incident ten years ago and return a confiscated bracelet, which had belonged to [[Suiren. As Ganryū is taken into custody, Naruto questions whether or not he will be alright. When the bunch return to the hospital, Akatsuchi informs them 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 then leaves in a hurry, without introducing himself to the three ninja. Once arriving with Yamato and the others, they await for a new ship to take them to the Island Turtle.

Trivia

 * Team Ganryū's flak jackets more resemble Iwagakure flak jackets than those of Kirigakure shinobi. Ganryū also wears a white forehead protector cloth; usually only seen on Kumogakure shinobi.
