|Alter Ego||Cure Sky|

Megumi Shiba (恵 芝 Megumi Shiba?) is a shy, kind, and cheerful 14-year old girl. She loves reading and stargazing, and she always knows when any sort of interesting astrological event is going to occur. Megumi finds it difficult to express her thoughts and feeling to other people, so she has a hard time making friends. Anytime she is asked about "space", Megumi gets super excited and will ramble on about it for hours if not stopped. She always wears a pair of usamimi out of her childish belief that it will cause the moon rabbits to visit her and tell her about space. As Cure Sky, she introduces herself as "One who reaches for the stars, Cure Sky!". Her theme color is blue.
