Lala is an anthropomorphic white creature, presented as one half of a twin-like pair with Kiki within Sanrio's imaginative world. She inhabits a fantastical setting where everyday events blend with emotional connections.

In "Kiki to Lala no Ohimesama ni Naritai" (1993), Lala prepares for the Hoshi Matsuri (Star Festival) with Kiki. Spotting a falling star, she dreams of wishes. Her trusting nature surfaces when Kiki deceives her, trading fake stardust for her candy. Discovering the trick causes Lala deep hurt, leading her to declare an end to their friendship, revealing her emotional vulnerability. Kiki's subsequent dangerous quest for a genuine wishing star results in reconciliation, underscoring Lala's vital role in their dynamic and her receptiveness to forgiveness.

The OVA "Kiki to Lala no Papa to Mama ni Aitai" (1994) focuses on Lala receiving a present from her parents, marking one of her happiest days and highlighting her affectionate familial bonds. Her emotional reaction reflects a longing for connection, emphasizing themes of homesickness and appreciation for family ties.

Earlier media, the film "Kiki to Lala no Aoi Tori" (1989), positions Lala within an adaptation of Maurice Maeterlinck's "The Blue Bird," framing her within a classic journey to find the bluebird of happiness, a tale of discovery and imaginative quests.

No concrete information details Lala's origins, species, or specific familial relationships beyond having parents. Her development across these appearances consistently portrays emotional responsiveness, whether through conflict with Kiki or expressions of familial affection. These narratives establish her role in exploring themes of friendship, selflessness, and the significance of family bonds within her fantastical life.
