"How can this be?!"
The young lady was the one who exclaimed in shock.
It had been over thirty minutes since she'd been battling Grey, and he hadn't even shown any signs of exhaustion; in fact, he was still almost the same as when the fight initially started. Other than the hint of blood on the side of his mouth, his disheveled hair, and ruffled clothes, his calm expression didn't give away the fact that he had been locked in battle for such a long time.
The young lady wasn't any better than Grey, but neither of them had sustained any significant injuries. Grey's attacks were not as powerful as the young lady's, and other than when he used his five-colored fusion orb once, which occasionally threatened the young lady when used, he hadn't been able to get any significant advantage over her.
