Stain moved away from the teens' attacks, jumping up and down the narrow alley walls while threatening them with knives shrieking through the air as they narrowly missed them. Stain's moves weren't those of a general street thug- he seemed to have trained for whatever purpose he expected in his acts. That was probably how he took down a professional so easily, not to mention Iida, who was a noticeable speedster of the class.
Midoriya felt a disturbing pressure as he fought the villain. Stain was unexpectedly stronger than how he imagined usual street thugs would be. He was more of a trained fighter, with a supply of throwing knives and a katana. Nensu was having trouble catching him due to his agility, and Midoriya himself was busy dodging the knives he was throwing. If only he could figure out what quirk he had, Midoriya could get a bit of an advantage over the fight.. hopefully.
"What happened?!"
He yelled.
"I got cut by his blade, and then I suddenly can't move!"
Iida replied, his face still facing the floor. 'So they weren't just knocked out, it was Stain's quirk that did it.' Midoriya thought. How he did it, he could only guess for now.
