Jesus fuck that book is huge. Isn't she, like, anemic? How does she even one-hand it like that?

Anemic doesn't mean she's too weak to hold up a giant book. It just that she can run't more than a quarter of a mile before passing out.
She probably have a good amount of arm strength since carry heavy books all the time is almost the same as lifting weights.
