Overcome
Mira fought against the shadow duo for over half an hour before she finally got used to their teamwork.
That doesn't mean Mira has found a way to overcome it; she's just no longer being led around by the nose.
She also realized that unless she relied on her overwhelming strength, she's going to have a hard time beating this duo.
If she tried attacking the swordsman, the archer would interrupt her, and hitting the archer with long-range attacks was easier said than done. It was constantly on the move, aiming for parts of her body that she hardly bothered defending.
That made the archer especially annoying because it never went for any killing moves. It only wanted to hit her; it didn't matter where.
The shadow duo's ability to read and adjust to the situation was also impeccable. Somehow, they were able to tell when she wanted to attack, defend, parry, or counterattack, and they could even tell when and where her attacks were going to land!
