The icicles crashed into the villain and shattered into small ice shards. The shots seemed to stagger him good. While guarding his face with both arms raised to a guard, he couldn't advance forward as the pile of ice shards rose. In that timing, Midoriya ran away from Nensu, and from the villain. He had one clear thought, and only that: calling the heroes here. He couldn't risk any more casualties, for Nensu and him and anyone else.
"Oh, no you're NOT!"
The villain must have seen Midoriya run in his guard-as he turned around, risking to take the icicle barrage by his whoke back, and faced Midoriya. As there was no Nensu between them, he was free to charge straight at the boy. Midoriya turned around, and almost collapsed on the spot. What he saw was a murderous gaze, towards some random teenager that has messed with his oh so precious plan to be executed on a day of a fair for heroes. The villain started a run towards him, the knife held tight in his hand.
