Koyuki Kazahana

is a famous movie actress, primarily known for portraying. She is the sole child of Sōsetsu Kazahana, the former daimyō of the Land of Snow. As an actress, she is known under the name.

Background
As a child, her father Sōsetsu would tell her about "spring", a season that did not exist in the perpetual-wintered Land of Snow. She would happily await her father's project in bringing spring to the land, and was given a key for that "treasure". However, her paternal uncle Dotō Kazahana killed her father for his treasure, leaving Koyuki emotionally scarred for ten 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".

Personality
At first, she appeared very cruel as seen when children asked for her autograph, but during the movie, she shows a kinder and warmer nature. Due to being emotionally scarred, she was cold and melancholic, with other emotions being merely "an act"; she eventually regained her true emotions when she met Naruto.

Appearance
She has long black hair with light-coloured eyes. She wore a green blouse over a pink jacket with brown gloves. As a child, she wore a dress with an obi just below her chest and a strap around her forehead.

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 ten 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.
