Mokona Modoki: is the name given to the two rabbit-like
Larg and Soel are copies of an original Mokona, who appears in Magic Knight Rayearth (another Clamp series). The two were created by Yūko Ichihara and Clow Reed (who appear to be aware of the existence of Sakura Kinomoto and all of the events in her world). One day, Yūko and Clow encountered the original Mokona, who was traveling through different worlds, and Mokona provided Yūko and Clow with the knowledge of alternate dimensions. After learning that one day a Sakura and Syaoran from an alternate world would come to their world to ask for help, Yūko and Clow created the two Mokona, basing them on the original but with slight differences, such as difference in size and the ability to talk (whereas the original Mokona would only say "Puu!"). Each Mokona was also given an earring which matched the color of the gem on its forehead, the blue earring seals magic power while the red earring boosts magic power.
In Chapter 133 of Tsubasa, Yūko explained to the TRC group that the two Mokona were created in order to stop the plans of Fei Wong Reed's wishes.
The full story of the two Mokona is told in Clamp’s Soel to Larg: Mokona=Modoki no Bouken (Soel and Larg: The Adventures of Mokona=Modoki).
We also learn in the Drama CD provided with the first Kei DVD that the Mokona chose the 14th of February for birthday.
