The first difference Kurogane noted in comparing this hallway with its lower counterpart was how open it appeared. The usual walls of the Sun Room were absent, replaced with new hallways bordering a railing that overlooked the Sun Room - another area that he had made a point of avoiding after one too many incidents. Above that opening the dim glow of the night sky filtered through the windows, improving the visibility enough to see that no other patients were around. Their absence furthered the feeling of openness and set the ninja even more on edge than he'd been upon entering the hall. He was so used to the enclosed spaces and shadows of the lower floor that made movement easy. This hallway had nothing of that, and created too much vulnerability.
Moving more cautiously, the ninja kept his weapon ready, concealed beneath his cloak as he turned down the first of the hallways. Out of his peripheral view he spotted the Chapel doors positioned behind the back railing and moved for them as he kept a watch on the open hallway and the area over the Sun Room. He didn't know what was in the below room, but he knew something usually took up residence there, and couldn't overlook the possibility that it might move at him.
