Paulette is a fairy and the fairy godmother of Cinderella in the anime Cinderella Monogatari, where she serves as a main supporting presence from the first episode onward. She arrives in town at the beginning of the story, carrying a suitcase and returning just in time for the local flower festival, and it is during this return that she first sees Cinderella again after a long absence and remarks on how much the girl has grown. Paulette was a close friend of Cinderella's late mother, Frances, and before Frances passed away she asked Paulette to care for her daughter. Paulette gave her word and has remained devoted to that promise ever since.

In personality, Paulette is gentle, warm, and quietly playful. She has a fondness for painting and is often seen outdoors sketching the scenery, and she also teaches painting to the children of the town. Her playful side shows at a costume party at Cinderella's home, where she dresses as a witch and cheerfully asks whether she looks the part. She tends to keep herself in the background, and many episodes end with her standing near Cinderella's window, murmuring quietly that things have worked out well and giving a small wave of her wand, which is in fact a paintbrush. In the Japanese version she is generally addressed as Palette.

Paulette's central motivation is the promise she made to Frances to watch over Cinderella, and nearly everything she does in the story flows from that duty of friendship. She also seems to enjoy quietly supporting other young people who are working toward their dreams, and she uses her magic on several occasions to help others besides Cinderella, such as Marcel, Nicolas, and Laure. At the same time, she respects Cinderella's independence. She deliberately avoids solving every problem with magic, preferring to let Cinderella and those close to her act on their own, and there are moments where she holds back even when using her powers would have been convenient.

Her role in the story is that of a hidden guardian and fairy godmother. Early on, one of her first acts is to give the gift of speech to Cinderella's animal companions: the dog Patch, the mice Chuchu and Bingo, and the bird Pappy. These animals keep Cinderella company, help with her chores, and watch over her wellbeing, effectively serving as Paulette's eyes. Throughout the series Paulette observes Cinderella from a distance, removes obstacles without being noticed, and occasionally views distant events through magical means, such as seeing Cinderella's whereabouts reflected in the surface of a basin of water. Her most significant intervention takes place before the royal ball, when she appears openly to Cinderella for the first time, transforms her mother's old dress into a beautiful gown, mends her torn invitation, provides a pair of glass slippers, and conjures a carriage, while warning that all of it will vanish at midnight.

The most important relationship in Paulette's life is the one she shares with Cinderella, which is shaped by her friendship with Cinderella's mother. Frances entrusted her daughter to Paulette, and Paulette treats this trust as a lifelong obligation, caring for Cinderella with a maternal gentleness even though she prefers to remain unseen. She also works closely with the animal companions, who act as her helpers in looking after Cinderella. Her connection to Prince Charles is less direct; rather than competing with him or overshadowing him, she deliberately leaves room for him to play his part in Cinderella's life, saving her magic for the moments when it is truly needed.

Paulette does not undergo a dramatic personal transformation over the course of the story. Her development is instead marked by a gradual shift from secrecy to openness. She spends most of the series helping Cinderella from the shadows, but at the ball she finally reveals her identity and provides help directly, and from then on her support becomes more open. Even after this reveal, she continues to exercise restraint and trusts Cinderella to make her own choices. Her notable abilities include transformational and restorative magic, granting speech to animals, observing distant locations, altering clothing, conjuring a carriage, and creating glass slippers. Her wand is a paintbrush, tying her role as a magician to her identity as a painter. Her magic has boundaries, however, as she herself warns that its effects last only until midnight.
