Kiki
Little Twin Stars (リトルツインスターズ, Ritoru Tsuin Sutāzu), Kiki and Lala, are a pair of characters from the Japanese company Sanrio. They were born on December 24th (Christmas Eve) on Omoiyari Star in the Dream Star-Cloud. To learn how to be the best, shiniest stars they could be, they traveled a long way to Earth.
Kiki (キキ, Kiki), the younger brother, has short blue (or sometimes brown) hair. He loves star-fishing and inventing things. His curiosity about everything can make him a little cheeky sometimes. He wears a long sleeve white gown and has bare feet.
Lala (ララ, Rara), the older sister, has long pink (or sometimes blonde) hair. She can be a little timid, and she loves drawing, writing poems, and cooking! Like Kiki, she wears a long sleeve white gown and has bare feet.
As siblings, Kiki and Lala are really close and always play together. Kiki looks out for his older sister Lala and also thinks it's his job to protect her. Since Kiki is very curious, he can sometimes put himself in a dangerous situation which makes Lala worry about him. Even in the rare circumstances the two get into a fight, the twins manage to get back together fairly quickly.
Kiki and Lala were introduced in 1975 and enjoyed popularity in the early 80s. They had their own 40th anniversary in 2015.
