When Will You Return My liege?

In the Demonic Empire… Inside a level two purple-colored dimension.

Four years ago, a masked higher demon made his appearance in this dimension, and ever since then, things had never been the same. Though the hunting event continued unhindered, the demons felt uneasy and always watched their backs, as if afraid that someone or something would attack them from behind.

"Dammit, how long will this continue?" A frustrated three-eyed and armed demon kicked the carcass of a crab-like beast to the side.

"Hey, he's close by. You might want to keep your mouth shut," another demon warned, looking around fearfully, as if afraid that someone would hear his impulsive partner.

"But how long will it continue?!" the demon shouted. "Since he came out, it's getting harder to find beasts, and the dimensional boss has come outside twice now! Two fucking times."
