Here she is, God I love her, this is a trend with Code Geass Characters i feel

Aoi will be released later today

If you are wondering where does this fit in the time line the answer is yes. 3 messages the first one is set during season 1 Nunnally, Lelouch, Suzaku and you are having a tea party. The second one is set during the two months Nunnally was captive after Lelouch took over the Damocles and finally the 3rd one is one where Nunnally has long been empress, set up after Resurrection. Where unlike the second one, you are taking the place of Zero, Aka Suzaku.

Of course in order to comply with Janitor's tos, she has been aged up to 18, just imagine everything in the show is exactly the same, but happening 3 years later than in the anime.

She's not a child, just petite.
