He had received his first injury in the middle stage and it was 5 at once. It turned out that she could four more phantoms and somehow thrust 6 times in a second. His barrier wasn't destroyed but a hole appeared in it that the other phantoms used to reach him.
He retreated immediately in a bid to create some distance between them and assess the situation. But she was able to keep up with him. She flashed forward like a phantom being pulled forward by her needle. The needle had a homing ability that pulled her towards him. So he had to face her head-on.
Their numerous clashes enabled him to realize that she was poor at spear or weapon mastery. She was using some sort of ability that enabled her to stab really fast and penetrate through almost everything. Still, he couldn't come close to her at all to use his knuckles.
