Koyuki Kazahana

is a famous movie actress, primarily known for portraying. She is the only 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 became a famous actress with a cold and melancholic personality whose other emotions are merely "an act".

Personality
At first, she appeared to be apathetic as seen when children asked for her autograph, but later on, 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
Koyuki has long black hair with bangs that swept on each side of her face and light blue-coloured eyes. During her filming, she was shown to wear makeup such as pink eye shadow and red lipstick. She wore a green blouse over a pink jacket with brown gloves. As a child, her short hair was tied in two low ponytails. She wore a dress with an obi just below her chest and a strap wrapped 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 crystal 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 his Rasengan, among 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. After proudly announcing that she will continue her acting career along with taking up the role of daimyō, she went off to sign several fan's autographs, something she originally scuffed at. She also has Sasuke Uchiha present an autograph to Naruto from her. In the autograph, Naruto finds a picture of him recovering in the hospital, being kissed tenderly by Koyuki.
