藍華 S. グランチェスタ
A main character in Amano Kozue's Aria, a Himeya Company gondolier-in-training. She has yellow eyes and dark blue hair, which in the beginning of the series was gathered into long, thin twin braids, later changing into a bob cut fastened by hairclips after Aika's hair was burned during a barbeque mishap.
Aika takes care of the Himeya mascot, Hime Granzchesta, and tries to keep fellow trainees Mizunashi Akari and Alice Carroll on an even keel. Her catchphrase is "恥ずかしいセリフ禁止!" (Saying embarrassing things is prohibited!)
