Key for girl trapped in dorm

[Norinia]

Anyone know where this is? She's trapped in the second floor of the girl's dorm in story mode. I only found 1 key before the mission started and it seemed to be used for the door on the first floor where there's a golden hairband.

I checked every dorm room I could (At least, pretty sure I checked every one) and there wasn't any keys lying on the ground like how I found the first key. Anyone know where it is? A girl's bladder is on the line!!! /sjk

Key should be found in the room next to the showers
