She would propose that she is 16 years of age, but at best Anais has the appearance of a 14-year-old.
She can be characterized by her large eyes and lovely face. When she flutters her eyelashes and winks, there isn't a soul alive who would refuse anything she asks for.
She has two personalities, Anais and Anabelle, which she alternates between. She is Anabelle when the big ribbon in her hair is up, but becomes Anais when her hair is untied.
Anabelle can be an awfully mischievous angel. She is happy, cheerful, and loves to joke around. On the other hand, Anais is of a gloomier nature at times, so much so that those around her seem to take no notice of her presence at all.
Anais has revealed very little of her identity to anyone else. She even seems to forget who she is herself sometimes.
No, it may simply be that she's forgetful by nature.
