Amane Ootori

Amane appears to be a very loved and respected member of the school, much like Shizuma Hanazono, although she is more of a local celebrity of Spica. She is often seen riding a white horse named Star Bright, which makes her seem more like a prince (a title which Shizuma later marks her with) from a fairy tale. Furthermore, she looks very much like a guy and in effect, a lot of the students at St. Spica are her fans. She tends to have a silent demeanor, which also makes her seem intimidating, making her difficult to talk with or approach.

She too has a crush on Hikari, showing her affection much in the way a man does for a woman. Amane, much like Yaya, looks out for Hikari and protects her when need be.
