Of course, a reward could only be collected if one could find the thing the reward was for. And as of the moment, Aoi had found absolutely nothing, though they hadn't made it a point to venture very far in, yet. Until they knew what they were dealing with, they wouldn't try to go deeper than necessary.
So, when they thought they'd gone deep enough, they turned around to head back to the entrance, only to stop dead still in the shadows when they heard...something. Wingbeats? Steps? Surely a monster would have wings, right? And oh, hoiw fascinating would if be if they could get some wings of their own.
Slinking closer, following the sounds they could hear, they tried to get a good look at what was there, probably not being too cautious since they had a slight problem with cockiness. Thinking nothing could get past them. The cockiness also drew a soft chuckle from them as they attempted to stalk whatever it was that was in the maze with them.
