Nensu was in so much pain, she couldn’t make the right expression, once she witnessed, with blurry vision, Midoriya being scooped up by a Nomu. By the time that happened, she lost consciousness, and never recollected on what happened beyond that. Even at the hospital, the doctors informed the other teens that she was very lucky to be alive after the attack; she could have lost a lot of blood; not to mention that she had bumped her head while falling, and that the nerves in her right arm were impacted, and was in great need of recovery after the removal of the blade. 
She remained unconscious for the next few hours, until the female teen had finally managed to awaken, the next day. She was told to go slow, and not move her right arm at its entirety.
