"My bad," Isa replied. "Sorry for coming in here like I owned the place, I already knew this place before I came here and knew all of you like the back of my hand, to be honest."
"Right, all the quirks you have, sorry," Uraraka apologized.
"What can I say, she fits in like a glove," Aizawa chuckled.
"So you can turn into different people?" Denki asked.
"Yeah," Isa said and then turned into Aizawa. "It's simple."
"So how did your date go, other than you killing Bakugo, was he actually dead?" Mirio smirked.
"Yes, and why don't you answer, Bakugo?" Isa looked at Bakugo.
"After I started walking and she stopped dragging me we had a lot of fun," Bakugo smiled. "She caught me with a cloud when I fell because we were rock climbing at the USJ."
"W-what?" Aizawa looked at Isa with slight shock and barely noticeable sadness.
"What would really happen if Aizawa erased your quirks?" Hawks asked. Isa then made a villain invisible and teleported them into the room from their jail cell.
"I would immediately collapse to the floor, let out a shrill scream, and curl into a ball crying, I won't be able to talk and I would stop breathing after a few seconds," Isa answered. "I've never had a negative thought in my life so I would be overwhelmed by the thoughts that I should have had in my past as they catch up to me."
"So you'd have a mental breakdown?" Deku replied.
"No, it would be worse," Isa answered. "I've never experienced anxiety, depression, sadness, or other things like that, I've experienced pain and fear though, but I'd stop breathing because of how overwhelming it is and die."
"So, your greatest weakness is losing your quirks?" Deku asked.
"Yes," Isa sighed. "I do have regret, that is a type of pain."
"There's no way that's true," Uraraka sighed.
"Fine then, erase my quirks, Aizawa," Isa said and looked sternly at Aizawa.
"No," Aizawa snapped. "I'm not going to do that."
"Isa would never lie about something like that," Monoma sighed sadly.
"Uraraka, what's gotten into you?" Bakugo snapped.
"She's probably a villain trying to infiltrate the school," Uraraka snapped.
