Well, that's because she's the primera. The source of her power is her life force. That makes primeras age slow twice or thrice as slowly compared to other people. The only way to grow up/look her age is for her to use her powers but she can't do that yet because ability users have to be awakened by the emperor.
why is she so fkn small it's pissing me off lmao
7 year old and waist height to a 12 year old is crazy work
She said that until she uses magic or something she's aging at half the rate, so her body is closer to a 3 or 4 year old
I mean at least they gave us an actual reason this time
