Diana is a fairy from planet Glimmer, 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 Rosalia 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 Valerie advice. However Diana also has a silly side, and can be very air-headed and naive.
