Nensu could only pass off as much flame as she could deliver, in order to keep Stain away. She didn't know exactly how long they should be able to hold off the Hero Killer, but based on the villain's ability to dodge some of their strikes, there was a possibility that they won't be able to defend themselves for long. She could only mentally pray that help would come for them soon. The cut she just recently received was still fresh, and the girl had to only give quiet winces from time to time, every time she decided to perform an attack. Her right arm was starting to shake from overuse, so Nensu was forced to redirect herself in using as much flame as she could. 
"Why do you think you enrolled at this school, Iida-san?!"
The girl shouted back at her fellow classmate, as she continued to keep her flames trained on Stain's proximity. 
"What made you want to become a hero? To help people and continue your brother's legacy, right?"
Nensu looked back at the immobile teen, with sympathy yet fierceness in her eyes. 
"Revenge is just not the way to go. If you take this route, you'll lean towards the darkness and corruption of justice and heroism. Trust me, don’t put red on your brother's ledger. Iida, he would want you to put this man away, for the sake of the people, not for your own selfish desires".
She could only hope that her words of wisdom would clear his thoughts.
