Rose is a kind and bubbly student in Bustier's class. She is best friends with Juleka Couffaine, although it is heavily implied that they are in a romantic relationship. She also suffers from an unknown chronic illness. She sometimes uses the Pig Miraculous to transform into "Pigella". Her weapon is a tambourine and her special power "Gift" creates a gift box that opens to reveal an image of the target's deepest wish. Her transformation call is "Daizzi, rejoice!". She is often called upon throughout the series.
Her villain form is "Princess Fragrance", who can brainwash people with her perfume. She has sometimes teamed up with Lady Wifi and Reflekta, and once with Horrificator and Timebreaker to form the Gang of Secrets.
