You got my approval on the Safira's nationality, but that's just my biased (Lusophone) opinion. Please wait for Windel's green light before posting.

Anyway, the reason why she's old like that and still a first is because she didn't had the opportunity to go to school before, right? If that's so, I think it's ok, otherwise, you probably should lower her age by a couple years, or make her part of a higher grade.
