Maybe so people won't be suspicious with how cracked she is? Like dabbling into black magic to be as good or something along those lines
Normally they come up with excuses "i learned in a dream" or like "its intuitive, im self taught" or like "i was taught by some wandering master"
The only justifiable reason i could think of is that learning requires external guidance. Like to level up you need some kind of outside magic help or something idk like how some pokemon evolve based on trading or items
The magic system might be different in this world there might be different requirements for learning magic than there are normally. Well just have to wait and see if it's ever addressed or not why she can't just learn it with her past knowledge.
I agree! I'm also waiting for it.
It threw me off so much that it wasn't explained immediately. Felt a little hand-wavy, considering that entire scene was her contemplating solutions for her family.
She was a cracked magician but still needs early education?
