The Queen rules the Pumpkin Kingdom alongside the King and is Princess Pumplulu's mother. A skilled seamstress, she crafted clothing for the kingdom's fairies and created the handmade Leff doll as a gift for her daughter. She cherished family moments, especially making pudding with Pumplulu and the King before their lives were disrupted.

Minister Warp imprisoned Pumplulu and used his powers to manipulate the Queen and King, causing them to forget their daughter entirely. Under Warp's influence, the Queen became preoccupied with overseeing mandatory pudding production for the kingdom. Her memories of Pumplulu remained suppressed until Haruka Haruno prepared a special pudding using the family recipe. Tasting this pudding triggered the Queen's maternal memories, restoring her recognition of Pumplulu and breaking Warp's control.

Following her liberation, the Queen joyfully reunited with Pumplulu and the King. She participated in the celebratory ball marking the kingdom's restored peace. The Leff doll she originally crafted for Pumplulu was later given to the Pretty Cures as a farewell gift, connecting to events involving Princess Leff in another realm. Her role concludes with the kingdom stable and her familial bonds reaffirmed.
