As soon as she sends those texts, a very faint ping echoes from somewhere above her. It's coming from the roof. Normally it would be impossible to hear through an entire floor, but the door to the stairs is open, as if someone had just gone up there. And then, a few moments after that - there's a thud that shakes this whole side of the building. Something big just collided with the roof.

A few moments later, Orihime gets a text back:

And then a second thud, harder than the first.
