Rose is Aura's best friend and Alicia's arch enemy. She is in charge of the Library Club at Crownsworth High School and enjoys reading mystery novels. She and Aura stop being friends as her gyaru transformation progresses.
Rose strongly dislikes the cheerleaders for their bullying, particularly of her fellow library club members. She also believes Alicia is responsible for the changes to Aura but struggles to find out how she is doing it.
As part of Alicia's schemes to break Aura and Rose's friendship, Richard is seducing her to be his girlfriend, and make it look like Luciela is Rose and not Alicia. Rose agrees to this to try and find proof of Alicia's influence over Aura's change, but she has underestimated Richard and Alicia's cunning, as Richard has dark plans for Rose.
Rose's Divine Gift was the Lunar Sorceress.
