Once Midoriya turned the corner, Nensu was already freezing a 2p robot on the spot, after letting her hand touch the ground. From there, Momo created a mace to swing at the frozen prototype, and smash it to pieces. Just as Nensu turned around to see another robot, she saw the same green-haired boy she had accidentally bumped into earlier. “Watch out! Behind you!”, she said, warning him of the other robot coming towards them. 

Running forwards to shield him, Nensu used her left side to blast fire at it, shielding the three of them, before quickly switching back to her right side, completely freezing it. She might get criticized by the observers for wasting her fire power, but she felt it necessary to protect her comrades.
