Cure Fortune has a strong sense of justice, and also helps the poor people. Cure Fortune also knows her duty as a Cure, and is excellent at fighting matches, as well as is not afraid to battle Queen Mirage, and her Saiarks.
As Cure Fortune, her uniform is similar to the other three Cures, with a dark grey vest with a light purple collar and a darker purple ribbon in the front. Her skirt is also light purple and is longer toward the back. Her arm warmers and boots are also very long, going past her elbows and knees respectively. Her hair is purple and appears to be in a loose ponytail, with a heart-shaped hairpiece with a ribbon flowing out of it on the left side.
- Stardust Shoot is the first finisher of Cure Fortune, debuting in episode 1. She first moves by saying "Light of the stars, turn into holy powers! LovePreBrace!" later as she activates her LovePreBrace, she creates a big purple star with her hands, and later shoots it at the enemy, while saying "Stardust Shoot!". As the star traps the enemy, Cure Fortune says "Stars, return to the skies!" and the Saiark purifies.

- In episode 32, when she inserts her Innocent Form PreCards into the piano, an error shows her with a LovePreBrace.
- Althought Fortune is the last one to join the team, she is the first one to receive the Innocent Form.
