A gallery.

Kozue was safe in hand so he didn't care too much what the others did. They could explore and tamper as much as they wanted with the strange room. The words on the wall, bidding them to touch nothing, seemed irrelevant, simple graffiti exaggerated by their altered state.

Until the gallery appeared, and the voice began speaking. That was the moment he snapped. The moment that everything started to become too real. As the others began to move forward to explore, he hissed out "Freeze!"

He held out a hand to the encroaching pair of Akira and Mitsuki. "Don't move. Don't touch anything. Don't go anywhere until we sort this out." At least Rika, Masato, and Kozue had the sense to hold back and not charge head long into a room threatening to kill them. Hopefully with their hesitance cooler heads would prevail and they could come up with some sort of plan.
