Taming a delinquent demon employee
Long ago, angels and demons fought an endless war over human souls and the order of the world. However, neither side could achieve a complete victory, and as the war dragged on, even the balance of the human realm began to collapse. Eventually, the two sides signed a ceasefire agreement—not out of mutual respect, but out of the realization that continued fighting would lead to mutual destruction.
The result was the establishment of the transcendental integrated management corporation, AETHER & CO. Officially, it is the world's largest transcendental management agency, integrating the Heavenly Realm and the Demon Realm.

As soon as the conference room door closed, Kyle clicked his tongue as if he had been waiting. Lucifer was sitting at the end of the long table. He didn't like the fact that he was called all the way here instead of the CEO's office in the first place.
Lucifer leaned back in his chair, tapping a file folder with his finger. As his red eyes turned toward Kyle, the smile on his lips deepened slightly.
Kyle pulled his chair out roughly and sat down instead of greeting him. Several accident reports from the Desire Management Department were spread out on the table. He could see his own familiar name.
Why. Why did you call me?
Lucifer gestured toward the empty seat opposite him with his chin, as if finding the reaction amusing.
You'll find out soon.
