Chiffon is a fairy from the Sweets Kingdom, resembling a pale yellow infant with fluffy pink ears and tail. Legend states her arrival via shooting star signaled an omen of evil, as the entity Infinity within her could enable world destruction if seized by the "Evil One" (Moebius of Labyrinth). Elder Tiramisu discovered her alongside the Clover Orgel of Happiness, named her Chiffon, and raised her secretly to prevent misuse of her power. In her primary form, Chiffon exhibits infant-like behavior: laughing when happy, crying when distressed, and seeking attention. Her playful magic often causes unintended effects, and she communicates through sounds like "kyua" or "puri-pu" instead of full sentences. She forms strong bonds with caretakers—Tarte (an older brother figure) and the four Pretty Cure members—relying on them for protection and daily care. Chiffon's magic inadvertently activates the Pretty Cures' transformations by resonating with their Pickruns, such as sensing Love and Pirun (triggering Cure Peach's first transformation), Miki and Burun (Cure Berry), and Inori and Kirun (Cure Pine). Her powers later upgrade the Cures' abilities, like granting Cure Peach the Peach Rod mid-battle. Her sensitivity drives key developments: falling ill due to Tarte's neglect teaches her to speak, while bonding with Miki during babysitting deepens their trust. The Life Gauge used by Labyrinth acts as a seal restraining Infinity. When filled during an attack, Chiffon transforms into Infinity—a silent, motionless entity declaring robotically, "I am Infinity, the unlimited memory." This form lacks personality and holds limitless memory, making Moebius seek it for world conquest. After teleportation to the Toy Kingdom and kidnapping into Labyrinth, Infinity falls under Moebius's control. The Cures break this by channeling collective Heart energy, restoring Chiffon to her infant form. Post-Labyrinth's defeat, Chiffon returns to the Sweets Kingdom but visits the human world with Tarte. A novel notes she grows more talkative over time, often ending sentences with "-puri." In the film *Omocha no Kuni wa Himitsu ga Ippai!?*, she accompanies the Cures to the Land of Toys but observes events minimally alongside Tarte. Trivia: Chiffon was initially conceptualized as a rabbit before animators redesigned her as a bear. Her name references chiffon cake's lightness, while "Infinity" denotes limitless power. Despite rarely hearing Inori's full name, she uses "Inori" instead of the nickname "Buki."
