Kiki is the younger twin brother of Lala, completing the Little Twin Stars duo. He possesses pure white skin and pastel blue hair, usually clad in a white robe fastened with a pink bow. A large yellow five-pointed star adorns his back. Bubbling with curiosity, Kiki loves star-fishing and inventing, though this inquisitive nature sometimes leads to cheeky antics. He displays a low tolerance for frustration, particularly evident when a troublesome Pegasus repeatedly annoys him during a mission to return it home. Kiki shares a close bond with his twin sister Lala, and together they embark on adventures, such as learning about stars, constellations, and meeting the Queen of Stars. Beyond stories, Kiki appears in several Tamagotchi versions. In the Tamagotchi P's, he is an unlockable costume for Pekopekotchi via the Sanrio Deco Pierce, transforming it into Kiki★Pekopeko. Within the Tamagotchi m!x and Meets (Sanrio Editions), he is a marriageable adult character found in Twin Stars Land; marrying him passes his hair and giant star traits to offspring. Marrying Kiki in the Meets version restricts marriage to Lala for two subsequent generations. He also features in non-playable roles or as costume inspirations in other iterations like the Tamagotchi Smart and Uni.
