The freezing temperature on her right side has been charged properly, while she continued her stare down with the individual. Nensu stayed calm, although her guard was up, if something were, either to interrupt it, or if male attempted to use combat. Under the city's authority, they weren't allowed to kill a villain without a license (if that's even right; I wasn't sure), but to defend themselves, if needed; that was her intention, anyway, in this scenario. She just couldn't strike first, since it was best to play safe, due to the civilians around them, as well as avoid reckless action. Both herself and Midoriya didn't even know what cards he was capable of playing, so caution was needed. Slightly turning her head to see the green-haired boy behind her, with a cell phone in his hand, Nensu figured that he was trying to call for help. Good. Perhaps she could give him some time, and keep the villain's eyes on her, until help comes. 

However, just as she turned her head to face the man again, an object went flying past her face, creating a graze upon her left cheek, and slicing a lock of her red hair; the piece falling to the ground. She gasped at the sudden action, just as she found herself face-to-face with her assailant, who was only centimeters away from her face, causing her to tremble. Not out of fear, but from...something else. 
[i]'No, not now. Not again'[/i], she thought to herself. [i]'He hurt you, little lamb. Like how every one of them does. Like how he does'[/i], she meant the Endeavor, which only awakened even more memories. They came in through flashes, to the point of an ache in her head, leading her to whimper.
