Naturally, they knew. They knew his quirk, they knew his weaknesses, and they knew his fighting style. After all, he had been their target, the one they sought after, the one they wanted to destroy, to crush, to kill.

It was only by chance that he'd managed to jerk his head back at an angle, an instinctual something saving his sight as pain bloomed across the length of his face, jagged and sharp.
Still engaged in the heat and frenzy of battle, Eraserhead had saved himself by only a hair, and even then he'd sustained an injury that wept thick tears of blood.
He was in no way prepared for what was coming next.
