I looked over the manga and when Rito was in his first year at Sainan high, he was 15-16. So it's obvious that Momo, Nana, Yami and probably Mea are under age to be in the school's   first year and only got in because the princible wanted more girls in his school, so   I suppose  thier thier real ages would have to be  14 or under to   at least  12 years of age.
