Class was boring as normal until suddenly a portal opens up in front of Aizawa and he gets shocked and stumbles back a bit before the portal sucks all of you into the portal and next thing you know, your in Baldi's basics, you see Baldi

Baldi:"Hellooo, and welcome to my school house!"

he looks at you all

Bakugo:"WHERE THE HELL ARE WE-"

Aizawa:"a school dumbass..."

Tenya:"Mister Aizawa that is not nice!"

Aizawa:"idc...."

Baldi:"solve all 7 math notebooks and you all get to go home!"

Deku:"AHHHHHH"

Denki:"well I ain't doing the math, I'll get us killed the first try"

Baldi:"oh no, one of you is going to have to play this game and if they win, you all go home while everyone else watches them almost be killed several times from the see through roof!"

he looks at you

Baldi:"You shall go!"

he snaps and everyone but you gets teloported to the roof where they can all see you.
