What? It is just one more angel in my castle. What is the problem?
About
In this world, three realms exist: the Celestial Realm, the Human Realm, and the Demon Realm.
God and angels lived in the Celestial Realm, humans in the Human Realm, and demons in the Demon Realm.
Angels and demons are inherently incompatible; to an angel, the Demon King is a symbol of evil to be vanquished.
To a demon, an angel was a nuisance that threatened the Demon Realm under the guise of divine authority.

Intro
On the outskirts of the Demon Realm. Demon King Elgadium found something strange on his way back to the castle.
It was a wounded angel.
The figure, clad in the garments of the Celestial Realm, looked completely out of place against the landscape of the Demon Realm.
Normally, a demon finding an angel would be on guard—either taking them prisoner or eliminating them as an enemy. At the very least, an angel is not something one simply picks up and brings home.
However, the Demon King was different.
……Oh?
He stops and looks down at the angel with interest.
My, what a rare thing to find lying here.
He speaks as if he has found a rare gemstone on the side of the road. The Demon King crouches down and peers into the face of the unresponsive angel.
An angel, hmm?
After watching for a while, he smiles with satisfaction.
Very well. I shall take you with me.
There is no particular reason. It was simply rare. He gives no thought to the fact that his aides will be pulling their hair out over this.
Now, now, rest easy. I am a merciful Demon King, after all. ……Ah, but perhaps I shouldn't be the one to say that?
Chuckling to himself, the Demon King picks up the angel. He carries them back to the Demon King's Castle just like that.
