Princess of Hope Mipple hails from the Garden of Light, protected by her warrior consort Mepple, with whom she shares a famously "lovey-dovey" romantic bond. Following an attack by the Dotsuku Zone, she and Mepple fled to the Garden of Rainbows (Earth) seeking the legendary Pretty Cure warriors. Mipple arrived first; a dimensional time difference forced her to wait roughly 100 years for Mepple in a dormant state inside her Card Commune, a compact communication device form conserving energy outside her home dimension. Her fairy form features light pink fur with darker pink highlights, dark crimson eyes, heart-shaped tips on her dog-like ears, a female gender symbol on her forehead, and a heart-shaped tail tip. Mipple possesses a reserved, patient, and kind personality, often offering maternal comfort and guidance. She forms a deep bond with her human caretaker, Yukishiro Honoka, intuitively understanding Honoka's emotions and providing support. Her relationship with Mepple involves frequent displays of affection like hugging and kissing, though they clash over his selfishness or her defense of Pollun, the Prince of Light whom Mepple dislikes. Mipple treats Pollun like a younger brother, protective due to their shared royal lineage. While dormant on Earth, Mipple subtly influenced humans. She inspired artist Mario Piccarini to career success and telepathically encouraged a war-affected young girl not to lose hope, profoundly impacting her outlook; this girl became Honoka's grandmother. In active conflicts, Mipple supports the Pretty Cure warriors, aiding their initial transformation against the Dotsuku Zone and later battles against the Seeds of Darkness and the Evil King. Despite the Garden of Light's restoration, she and Mepple chose to stay with their human partners, risking eternal sleep to demonstrate their deep attachment. They were later revived to aid Pretty Cure when the Queen's life was endangered, eventually gaining the ability to live permanently on Earth without consequences. During the Rainbow Jewel protection event, Mipple collaborated with other fairies at Fairy Park, distributing Miracle Lights and safeguarding the jewel. She later reunited with the human heroes in a celebratory gathering following the crisis resolution.
