>Check the rest of the room for interesting things; interesting in the sense of possibly helping to figure out what's going on.
This is a difficult task. You're not sure where exactly you start looking for ghosts. I mean, Kogasa is tied to something, but if it is Hijiri and her crew, they're probably tied to HERE.
Even then, you're just getting brief flashes. Not even full on ghosts.

You decide the debris is worth looking into. The pieces are light enough you can handle them on your own, even if you move a bit slowly with the pieces.
You're not sure where the debris might have come from, whoever moved it did a good job of cleaning up any clues. You find it rather clear there is way too much debris here, though.
The hole in the ceiling seems to have an empty space above it. Maybe it's some kind of attic.

> Shouldn't Byakuren's room have some kind of protection from this stuff? You know, since she's a monk and all?
Well, as much as Patchouli would probably know something, Eiki and Komachi judge people all the time, and probably judged Hijiri if she moved on. They'd probably know a lot more about what the situation here is.
She was however, a monk who hung out with a ghost captain. You figure she wouldn't place something that would mess with Murasa.
...You manage to excavate a glimpse of a PURPLE OBJECT in the debris. Something about the object seems familiar, as if you'd seen it recently.
You're almost afraid of what it could be.
You could probably pull it out of the debris, should you?
