Diana is a fairy from the magical kingdom of Chalcedonia, and Princess Rosalia's most loyal and trusted knight. She is normally very serious, calm, and collected, but becomes impulsive and reckless when it comes to the princess. She loves the princess more than anything and would do anything to protect her. She takes her duties as a knight and Valerie's fairy guide very seriously, and is the level-headed of the two, often giving her advice.

She doesn't get along with Amber, however the two of them seem to be close.
