[b]Right Hallway Door: 

There's a bit more hallway past here, but it seems to end in another door. This one doesn't appear to be locked, and nothing is on the walls leading to it. No windows are visible in this hallway, but light seems to be flowing in from somewhere... 

Right Hallway Door #2: 

There's an odd engraving on this door. The image appears to be split in half, with the left showing an angel and the left a demon. The demon is faded, but there appear to be some small circles lying around it in a larger formation. The angel seems to be holding a daisy and book. 

...Something appears to be drawn in the book, but it's faded.

Kido followed behind as best he could, taking a moment to scribble something in a small book he carried before stuffing it back in his pocket. By the time he had caught up, he could see that the door had swung open easily following the turning of the key. A slight shiver ran down his spine, but he tried to ignore it and walked closer. "It worked! How exciting, r-right?" He flashed a small smile before turning to the door further down the hall. "Hmm...that's an interesting picture, though. I wonder why it's here?"
