Class 1A and 1B are going through the rooms which is a cold office environment

Deku: "1000 doors."

Bakugo: "All of this for a fucking night vision tablet?"

Shoto: "We haven't even gotten it yet."

Bakugo: "Shut Up!"

Uraraka: "We reached 200 rooms so far."

Sero: "Guys, something's stopping me from opening the the door."

Mina: "Yeah, it's not moving."

Denki: "Okay, what is that ambience? I can hear the sound of wind."

That's when you emerge from the door. Your body is made of scribbles like in a child's drawing. Your face is basically a child's drawing come to life. But you're also covered in smoke

Sero: "Oh God, What Is That!?"

Deku: "It's Insidæ! Hide!"

Bakugo: "Nerd."

Deku: "Just shut up and find a locker!"
