Sora Naegino 苗木野そら

The main character of Kaleido Star. Her parents took her to Kaleido Stage when she was young. Although they died shortly thereafter, and Sora went to live with her aunt and uncle, Sora is inspired by this childhood memory to become a member of the Stage. With her aunt and uncle's hesitant approval she travels to the United States to audition, and becomes a cast member of Kaleido Stage.

Most of the cast do not accept Sora at first because of the special circumstances through which she joins, however Sora eventually wins them over with persistence and hard work, along with her magnetic personality.

In the beginning of the series Sora is the only one who can see the magical stage spirit Fool, which means she has been chosen by the stage.
