Nuts hails from the Palmier Kingdom as one of its two princes, sharing this role with Coco. Renowned as the kingdom's most scholarly and intelligent figure, he possesses vast knowledge and deeply values written words. A pivotal moment in his past defines him: believing the wounded Pinky outside the gates required aid, he opened them out of genuine trust. This act unintentionally allowed Nightmare to invade and obliterate the Palmier Kingdom, a catastrophe for which Nuts harbors profound guilt. During their escape after the kingdom's fall, both Nuts and Coco suffered severe injuries. To heal, Nuts became encased within the Dream Collet—a powerful artifact he vowed to protect at any cost. While it mended his physical wounds, it trapped him temporarily. The trauma of his mistake forged his personality into one marked by intense self-reproach and deep reluctance to trust others. He adopted a stern, serious demeanor, rarely smiling, and demanded unwavering focus on their mission to restore Palmier Kingdom. His character displays pronounced stubbornness and pride, particularly in refusing to owe debts. He esteems honesty above all else and despises lies. Across media, including the PreCure All Stars DX films, Nuts maintains constant vigilance against threats to their objectives. In DX2: Kibou no Hikari - Rainbow Jewel o Mamore!, he and Coco are abducted into the Mirror Kingdom by the villain Shadow, who seeks the Dream Collet to harness Pinkies' power for domination, prompting a rescue by allies like Migirin and Hidarin. Later, in DX3: Deliver the Future! The Rainbow Flower That Connects the World, his attunement to disturbances proves vital when he and Coco sense anomalies as movie-exclusive worlds merge and past movie villains resurface under dark influence. His journey centers on safeguarding the Dream Collet, aiding in collecting the 55 Pinkies to rebuild their homeland, and confronting his past actions while navigating the complexities of trust and redemption.
