^ What do you mean ?

Are you talking about how Akane noticed that Anya puts little effort to her tests, yet achieve such high scores ? It's pretty natural, if he whants to obtain Halberd, then he needs to take notes of how strong his rival is. Beside that, she already easily owned one pair with Harudori, so he is probably checking, if it was thanks to the weapon, master, or both.

I wonder if we will see a Black Star vs Akane
