Arc 7From Sasuke to the Land of Snow
Ueno Kei helped Tsunade take office, dealt with Sasuke’s defection, and secured the Land of Waves for the Land of Fire amid a conflict with Kirigakure. He then began escorting Princess Kazahana Koyuki to the Land of Snow, promising Sandayu that he would protect her.
- Tsunade became Konoha’s Fifth Hokage, and Ueno Kei left to address the Anbu’s personnel shortage.
- Sasuke defected to join Orochimaru, and Tsunade sent Shikamaru’s team after him while Kei declared Sasuke a rogue ninja.
- Kei reached the Valley of the End after Naruto’s fight with Sasuke, but sheathed his blade when Naruto pleaded for Sasuke to be allowed to leave.
- Kei helped negotiate the release of Sunagakure’s captured ninja, then joined the mission to the Land of Waves after its daimyo requested incorporation into the Land of Fire.
- Kei fought Kirigakure’s forces in Cold City, killed Mist Rain, rescued the daimyo, and took Ao’s Byakugan before the Mist and Land of Water troops withdrew.
- The Land of Waves joined the Land of Fire, and Kei received an escort mission for Fujikaze Yukie, whose true identity was Princess Kazahana Koyuki.
- Kei tracked down the reluctant Koyuki, brought her aboard the ship to the Land of Snow, and promised Sandayu he would ensure her safety.
