What did you do, Hasegawa Mio.
"Sayaka, I... don't really want to mess with Hasegawa anymore."
I was talking with Marin, the girl I had sent to report back to me regarding Mio's situation. She's always been skilled at gathering information and covertly mixing with others, but it seems that Mio is a step too far.
There's not much point in trying to push her. Against someone like Mio, I would have to take more direct action than I usually like. Using other people would cause more issues than it would solve. Fighting in this school is an information game—you need to find out the weaknesses of the other person since direct confrontations aren't very effective at making any real impact.
Mio is like an invincible entity by the standards of the school. It is impossible to manipulate her since she leaves no weaknesses to be attacked.
The only trump card I held was her Mission.
It was the only thing that might give me an opening to defeat her.
