Lulun is a fairy princess from the Garden of Light, known as the one who weaves the future. She is the younger sister of Pollun and shares a close bond with him, often looking up to him as a big brother. Her personality is gentle but somewhat spoiled and prone to crying, especially when she is upset or scared. Despite her initial timidness, she becomes braver over time, particularly when the Pretty Cure are in trouble. In the events of the film Precure All Stars DX: Minna Tomodachi—Kiseki no Zenin Daishūgō, Lulun is separated from the other fairies and falls from the sky, where she encounters the Yes! PreCure 5 GoGo! team. She is being chased by a fragment of the monster Fusion, which compels the team to transform and fight. Her primary role in the story is as a supportive fairy who, alongside other mascot characters, helps rally the Pretty Cure and provides encouragement. She holds a special ability to transform into the Miracle Commune, an item that grants Shiny Luminous the power to access the Heartiel Brooch, thereby strengthening her abilities. Lulun develops a maternal bond with Hikari Kujo, who becomes Shiny Luminous, and she often seeks comfort and guidance from her. Her speech pattern includes ending sentences with the suffix lulu. While she does not engage in direct combat, her presence and ability to empower others are vital to the heroes’ efforts against Fusion.
