If Nanami asks around for how to access the rooftop, she'll learn that the stairs up is located on the right wing of the fourth floor, which she currently isn't able to access. If she presses her ear against the door, she may occasionally hear sounds of shuffling as if made by something very large and very heavy moving around, and will have the distinct feeling of being watched despite there being a solid door in the way. At times, she may catch the faint smell of rotten egg.
Something appears to exist on the right wing of the fourth floor, and she may assume that until more is investigated and this is dealt with, safe passage to the rooftop won't be possible.
Plot Clue.
