In his book, Hishida said he wanted to model Pretty Series after Gundam and be aimed at 13 year olds because there isn't much content targeted towards them, but he had to compromise for 9-12 year olds because of what Tomy and Avex wanted. AiPri definitely feels respectful of that and it wouldn't surprise me either if that's why it appeals to an older audience as well.
