Aoi has chest-length dark blue hair and sky blue eyes. Casually she wears a pearl blue dress with light blue lining and blue ribbon. A band of navy wraps beneath the chest, and worn over this is a milk blue bolero. Included are boots matching the colors or her outfit.  Her school uniform is worn normally. As Cure Crystal her eyes and hair gets lighter.

Personality 

When she was first introduced, she seems like an elegant and quiet girl, but also quite understanding. She is modest and hates to put anyone through trouble, going so far as to initially refuse any help. Aoi is also quite calm and patient, not even appearing phased as the others told her about Pretty Cure, and she tried to politely spare their feelings when refusing their request.
