~~~~~~~~~~~~~~~~~~~~
I'm Y/N L/N, one of the angels sent by God to protect my little boy. He isn't actually my child, but I was sent to the mortal world to watch over him.

I am Sans, a demon from the pits of hell. I have come to destroy a particular little boy. According to my master, Satan, God wanted to protect him by sending one of his angels. I'm going to kill that angel too.

I swear I will protect him no matter what

I swear I will kill him, no matter what.

Because that is my duty.

🖤Actual story starts now🖤

I flew towards the mortal's house, my wings glowing as I went through the crisp evening air.

Ah, there he is! I smiled in happiness when I saw the little boy jumping around as he played with his....um I think they're called "toys" in the human world.

As I flew closer towards him, I bumped into a wall and was sent swerving.

"What the hell? Why are there walls in a forest?" I muttered to myself, groaning in pain.
Looking up, I froze in fear. There was a demon in front of me. His Red undershirt enhanced his huge horns and dark red eyes. He also had a black leather jacked with fuzz on the hood, long claws, sharp teeth with on gold tooth and black basketball shorts with red stripes on the side.

He was......SCARY AS HELL!!! I cowered in fear, facing the tree I bumped into so I wouldn't have to see his scary face.

"Who the fuck are you?" he growled at me.

Taking in my glowing appearance and white wings, he smirked.

"Oh? A stupid little angel, wanting to die, huh?"

I shook my head, wanting to live. Demons were our worst enemies, being able to kill us with one scratch from their claws.

And us angels couldn't use our powers to protect ourselves, only to protect someone or something else.

"Please don't kill me," I whimpered, facing the demon and trying to act brave.

Well, I was miserably failing.

The demon stared at me curiously, tracing a claw along my cheek. Ouch. He chuckled darkly before extending out his claws.

"You're beautiful, angel. I want you to be mine."

"What????"

I must be going insane. What a weird thing to think when you are about to die.

The demon gently placed his claw on my heart, making me freeze in surprise. And pain.

Cold, so cold. It felt like my soul was being sucked out of me, like I could never feel happy again.

After 3 painstakingly long minutes, the demon took his claw off my heart.

"What did you do to me!?" I demanded.

"I just made you mine," he shrugged. "Your soul belongs to me now, and you die if you don't accept me. Got it?"

"Then I just have to die to be free of you?" I asked happily.
