There will be a music room that you can't get into via the front door on the first floor of Evil Spirit Club, but there's a side door allowing access. While Elizabeth explains it to you, Yukiko comes in to request the same thing, so you'll have to bring her along with you. When you get to the music room, check the door and Yukiko mentions something about using oil. Check the northwest corner of the room to find a janitor's closet, which will out you into a fight with three Phantom Mages (you've fought these before; weak to fire). After the fight, go back to the door and it will open. Although it looks like another fight be incoming, you're safe for now, so return to the Nurse's Office to finish the request.
