Trivia

 * Ai-chan is the third baby fairy in history, after Chiffon and Potpourri
 * Ai-chan and the way she is taken care of is really similar to Chiffon, because both are baby fairies, both need to be fed by bottle, which comes from the cures' transformation device, and both have no partner cure.
 * Ai-chan is the second oldest baby fairy, because Potpourri has already bonded with Itsuki, Ai-chan gos to school, according to episode 9 title, and Chiffon isn't even talking.
 * AI-chan has similar look to Chibi Chibi from Sailor Moon anime, because of the hairstyle, both are little and both are described as cute.
