During the first 23 or 24 episodes of fresh pretty cure Setsuna is actually evil and works with Labyrinth under Lord Moebius's command. She is called Eas while working with Labyrinth. After encountering Love and seeing her happy energy it starts to rub off on Eas and it eventually leads to her rebirth as Setsuna/Cure Passion. Although it's hard for her to move on when Labyrinth tries to get her to rejoin them as Eas once more. Setsuna isn't very good talking to people socially but since the girls are with her she is fine. She continues to fight Labyrinth as Cure Passion.
