"Though it's unlikely they would have much range outside of the room they've been placed in, if they're placed indoors." She considered this fact for a moment. From the roof... that wasn't an impossible proposal. However, it *was* reliant on the Daidouji family also failing to consider that possibility. And, well, if they were anything like what she expected, well... "It's not impossible they didn't mark everything," she began, "But the Daidouji probably considered that fact already. Still, it's worth checking out once we get there."
