Megumi Aino is an ordinary elementary school student known for her kind and caring nature, especially towards her friends. During a specific event, she encounters the fairy Candy. Candy grants Megumi temporary power to transform into a Precure warrior named Cure Lovely, enabling her to help protect her friends and the world from a threat.

As Cure Lovely, Megumi wears a primarily pink costume decorated with heart motifs. She joins a battle alongside many other Precures, contributing her power to their collective effort. This transformation and her role as Cure Lovely occur solely within this single event.

Once the conflict is resolved and the threat neutralized, the temporary power is relinquished. Megumi returns to her normal life as an elementary school student. No other transformations or adventures as Cure Lovely are documented in official media, and no background story or development beyond this event exists for the character.
