Looking through the rooms where people were experimented on was hardly what he'd had in mind, but if it kept Kurogane busy and was enough to please Tsubaki, then he wasn't about to argue. While he had no problem with the girl's excuse, valid or no, Kurogane obviously wasn't buying. Just because it'd gone unannounced didn't mean it couldn't be happening. She could have a roommate that vanished or some other circumstance to lead her to that conclusion.

He gave a shrug to Kurogane, leaving it to him. As far as Yuuhi remembered, he hadn't come up this hallway before, so whatever they came upon was more or less new to him. It was going to be difficult to see though, since fewer and fewer people with lights were in the deeper halls.
