Aki was described as mysterious when Uta, Anna and Yuki first met her. She was a transfer student, a year younger than the rest. She is always seen quiet, and hardly ever talks, making it hard for her to make friends. It was later revealed that she was from Melody Land. After becoming a Cure, her personality showed a change, and she became friendlier and more outgoing.
A new student, Murasaki Aki, transferred into Uta, Anna and Yuki's school. Aki was a year younger than the rest, and is seen quiet and hardly ever talks, making her a loner. She later met the trio in the hallway, stating she knew their secrets. The trio were shocked, asking who she is. She introduced herself as Murasaki Aki and said she was originally from Melody Land, much to Nara, Maple and Oto's surprise. She revealed that she was actually a Cure, who didn't use a Melody Commune, which means she didn't have a partner. Yuki asked where she lived, and Aki stated with Mr. and Mrs. Murasaki, her foster parents. She first transformed in front of Uta, Anna and Yuki at Episode 24, also her first appearance.
