Parallel-world selfcest setting.
Cold on the outside, warm on the inside demon king x kind and steadfast archangel
"Sleep with me, and I'll let you go after forty-nine days."
"...Your Highness, noble Demon King, could you maybe give me a whole body first? Look at me walking around in a cat's body. Is that appropriate?"
Devil: ...
Just how beautiful is the holy son of Best Theological Seminary?
From the moment Raphael was born, everyone praised him: "A face kissed by angels."
As the divine holy son of Best Seminary, he always showed the world elegance, nobility, and gentleness.
But lately, every night he is randomly summoned to become some object beside the Demon King.
When Demon King Devil is reading, his subordinates chase a suddenly gender-swapped magical pet cat all around the palace.
When Demon King Devil drinks water, his black obsidian cup suddenly speaks up: "Hey, buddy, I just wanted to ask, what toothpaste do you use? How come you don't have any bad breath?"
And when Devil is about to bathe, before he even steps into the water, the exquisite cypress bathtub starts muttering: "My God, this is such a terrible sin. See no evil, see no evil, "
Devil: ...
Raphael always thought these were just dreams.
So he let himself go completely in his dreams and had a wonderful time.
Until Devil grabbed him by the throat, his enormous black wings pinning him firmly in place.
"Raphael, don't try to test my limits. You're as weak as an ant right now. It would be effortless to destroy you."
The sensation of suffocation and the imminence of death swept over him all at once.
Raphael suddenly realized that the being before him was a real, powerful Satanic demon.
...His lifelong nemesis, whom he had always believed in.
The church teaches: People must not be greedy, must not indulge themselves, and must not defy God's will.
The glory granted by God would be his honor for all his life.
But Devil brought him to the transformation pool, where the crystal-clear water reflected his whole form: dressed in a snowy white robe, with two broken white wings trembling gently behind him.
A fallen angel.
"Look at yourself."
Several black feathers drifted gracefully down onto the rippling water.
Devil wrapped his arms around his waist from behind, his cold skin pressed against Raphael's warm ear. His low, slightly hoarse voice slowly sounded like a bewitching whisper:
"Raphael, do you remember who you are now?"
