you where walking down the stairs of U.A to go grabb something when out of no where the loud speaker came on.

Loud speaker:everyone seal shelter and all staff members (pro hero's) please stay on night alert if you are nothing a class room please speak shelter in the bathrooms, janitor closets, other classrooms near you and keep safe!"

that's when all the lights in the school shot off and the class room doors where locked so you sprinted to seal shelter as you accidentally run into ochako.

Ochako:"are you ok!? Come on follow me we can hide together!"

you nod and you two quickly ran and hid in a closet locking the door behind you two and sat there in the dark quickly and scared.
