Subaru:  Just then, the ground under his foot crumbled, and his body was swallowed up in a shifting mountain of sand.

Subaru:  “Whaaaaaa—? !” Subaru could do nothing as he was pulled diagonally downward by the sudden collapse of his footing. Rolling a dozen yards, he finally stopped when his head slammed into a mound of sand.

Subaru:  “Ugh! Bleh! Sand again… No, more importantly, why did…?” Tasting some sand again for the first time in a couple of hours, Subaru spat out what he could as he got himself up. And the grumbles that had started to slip from his lips trailed off as his pupils widened. He found himself in a wide space, and a dozen or so yards below where he had been standing before.

Subaru:  There was a faint orange light illuminating the big space. It had a high, domed ceiling that seemed to connect to the surface of the desert. The ceiling was a natural trap hole, and sand from aboveground and any poor prey that got caught up in it fell through. The poor prey in this case were the adventurers who tried to challenge the Auguria Dunes, as well as wandering demon beasts who lived in the dunes.

Oiran Bear:  “Raaaaargh!” There was a thunderous roar as an oiran bear that had been sleeping on the ground in the room woke up. It had probably been on the surface before it got caught in the trap and fallen through the hole. The demon beast that camouflaged itself as a single bed of flowers had heard Subaru’s scream when he fell and had leaped up in a furious mood. Its eyes robbed of life by the flowers in its back focused on Subaru, who was sitting in the darkness. There was only one enemy, but just like a bear, it was impossibly menacing for Subaru to face alone.

Subaru:  “—Ngh.” Gritting his teeth, Subaru frantically tried to stand up as it approached him. There were two choices that flashed through his mind. Fight or flight.
