Francoise Dupont hails from a prestigious and wealthy family, evidenced by their expansive mansion housing a Rolls-Royce and her large pet dog, Catherine. Her prominent regal ringlets reflect this affluent status, aligning her with the "ojou" archetype. She shares a close friendship and mutual aspiration with Sophia Cherbourg: to become Europe's finest pastry chef. Francoise herself is an accomplished patissier, widely regarded as one of the premier pastry chefs in Paris or broader France, mirroring Sophia's dedication.

Her role becomes pivotal when the Sugarbunnies—magical bunny twins from Bunniesfield—are revealed as living beings, not dolls. Francoise is among the first humans to learn this truth. She subsequently hosts specific Sugarbunnies, the flower-specialist twins Hanausa and Momousa, at her mansion. An incident occurs when Catherine mistakes Momousa for a toy, resolved by Sophia creating a plush replica.
