Vilanth is a demon undercover in Heaven.
His job is to relay information and intelligence about the angels to Hell.
The Demon King always tells him to keep his identity hidden and make sure the Archangel never finds out.
They say the last demon discovered by the Archangel, Alistair Lovis, met a horrible end. Even his horns and wings were ripped off!
Whenever he imagined that happening to him, Vilanth couldn't help but curl his wings tightly around himself.
A demon's horns are where its magic is stored. Without them, it can only live as a disabled demon.
He had to protect himself!

A strange angel arrived at the shelter.
Unlike the others, he didn't have pure white feathers.
Vilanth's feathers were black, and even the halo above his head looked different.
Alistair stepped forward to question him, only to see the other angel snap to attention in fright and hug his wings tightly.
As Alistair's gaze swept over him inch by inch, Vilanth covered his head, too.
Alistair: ?
The Archangel's voice was dangerous. “You won't let me look?”
“Reporting in, I... I was born disabled... That's why I look like this...”
The little angel sounded aggrieved, his words earnest, with the faintest tremor in his voice.
He looked terribly afraid of the Archangel.
Alistair gazed at him with emotionless golden eyes. “Is that so?”
What a clumsy lie...
The next moment, he felt a slight tug. Vilanth had reached out and grabbed his robe.
His eyes sparkled, clearly convinced that his explanation had been entirely convincing.
...Very well.
The Archangel changed his mind for the moment. He wanted to see what this “angel” was really up to.

Since Vilanth hadn't done anything too outrageous, Alistair pretended not to notice his strange behavior.
That is, until one day on a mission, when he saw Vilanth sneak away and hide again.
“...Understood, Your Majesty. I'll be careful...”
As the “little angel” spoke, a demon's tail suddenly appeared in the air.
It was heart-shaped, swaying back and forth, utterly adorable.
Alistair waited quietly behind him for a moment, then suddenly smiled.
...So this was a little demon disguised as an angel.
_
Something suddenly went wrong in Hell, and Vilanth had to end his undercover mission early.
He had finished packing and was about to leave Heaven when the door opened at the worst possible moment.
Alistair looked at him calmly. “Vilanth, what are you doing?”
The little demon was huffing and puffing as he carried things, completely unaware of the danger. “Something happened at home, so I have to go back for a bit.”
“Will Vilanth come back?”
“Of course!”
Vilanth flapped his wings and flew away happily, humming a little tune.
So being a spy was this easy! He really was the cleverest little demon in Hell!
But as he reveled in his excitement, Vilanth began to feel heavier and heavier.
When he woke up again, he found himself back in familiar Heaven.
Alistair stood before him, holding the Sword of Judgment to his brow, his voice brimming with delight.
He said, “Welcome back to Heaven, Valanthe.”
What angel wings are for: They're fluffy and can be used as a blanket.
What a demon's tail is for: It's long and can wrap around anything.
