When she was young she met Holly Teulle who regards Cindy as a baby sister.

Prince Noctis's party encounters Cindy when their car breaks down in Leide.

The prince and his friends place the utmost trust in Cindy's maintenance work.

However, there is more to her than just her bubbly personality and sunny demeanor, as she is also responsible for having revitalized Hammerhead when business started going downhill.
