Love it, not a reincarnation and thus a "strong" child, because actually 20+ years old. But just someone that got strong by what she experienced in her life thus far.
I like how for the most part she really is "feral" but not overly aggressive or short sighted because of it.
One thing that does bother me is that, as I understand, she was abandoned at birth, but does remember the emperor and his promise. Seems like either a plot hole, or there is more going on.
