Background
As a child, her paternal uncle Dotō Kazahana killed her father for his treasure, leaving Koyuki emotionally scarred for 10 years. Ever since, she changed her name and appearance to Yukie Fujikaze, and eventually into a famous actress with a cold and melancholic personality whose other emotions are merely "an act".

Plot overview
She returns to her home in the Land of Snow for a movie, only to encounter Dotō again. She is targeted for her necklace, the key to her father's treasure. While imprisoned, Naruto Uzumaki (who happens to be one of her biggest fans) tells her of his devastating past and how he overcame it. After escaping from prison, Koyuki gives Dotō her necklace and attempts to stab him. She is then kidnapped by Dotō, as he discovers the treasure is a generator to change the Land of Snow into the Land of Spring. Naruto ultimately defeats Dotō with the encouragement of Koyuki who remembers her father as she looks out to his achieved dream, the Land of Spring, and sheds tears of joy and truly smiles for the first time in 10 years.

With her film complete, Koyuki explains that the Land of Spring will temporarily become the Land of Snow every winter. Sasuke Uchiha presents an autograph for Naruto from Koyuki. In the autograph, Naruto finds a picture of him recovering in the hospital, being kissed by Koyuki, who smiles happily at him as she signs more fans' autographs.

Trivia

 * "Kazahana" means "snowflake" while "Koyuki" means "a light or powdered snow".
 * Her character is very similar to Toki and Haruna. All three of them are daimyō, were in disguise, their fathers were assassinated, and endured a tragedy which made them act cold towards other people until meeting Naruto. All three seemed to grow fond of him as well.
