When Squad 7 are tasked with guarding Yukie Fujikaze, a famous actress, Naruto, Sasuke, Sakura and Kakashi journey to the Land of Snow only to discover that Yukie is actually the princess of the Land of Snow, which had been taken over by rogue ninja when she was a child. The leader of the rogue ninja, Doto Kazahana, wanted Yukie's crystal necklace in order to unlock the Land of Snow's treasure, which Yukie's father had hidden before being assassinated. After various battles between Squad 7 and the rogue ninja, resulting in the death of all of the latter, their leader Doto succeeded in obtaining Yukie's necklace, only to discover that the "treasure" of the Land of Snow is a generator designed to melt the snow and thus bring Spring to the country. Doto was then killed by Naruto in a manner reminiscent of Yukie's on-film character Princess Fun's defeat of the villain Mao, involving "rainbow chakra".
