Yukari is the heroine of the story, a high school student who is tired of the meaningless and repetitive life that has been forced upon her by her uptight mother. She eventually models for Paradise Kiss after being "kidnapped" by Isabella and whisked away to Paradise Kiss' atelier. She is often referred to, inexplicably, as Caroline by Miwako.
Yukari begins the series as a pretty faced, yet rather unattractive in personality, high school senior that studies dutifully for university entrance exams. When she meets the ParaKiss crew, she begins to discover new depth to her personality and life.
In the anime and manga, she ends up married with Hiroyuki.
In the live-action movie, she ends up with George.
