DemonStuck [Dave x Reader]

((Sorry for my absence. I was working on my rose cosplay. I will include a picture above. Enjoy the chapter.))
-Dave's Pov-
I took a deep breath and sat up on my bed. It's been two months since (Y/N) left. I'm not very worried anymore. I have a new interest. Terezi.
(Two years later)
-Your Pov-
Do you think this is the real him? I asked the demon within me. Im not sure, but we are definitely close. She answered. I heard the pounding of my feet on the ground as I ran into a nearby cave. Rumors have been spreading about a half-demon bent on killing her father. No one dares to fight me. They know what will happen if they do. I had one hand on my sword handle and prepared to strike. "(L/N)" I called and grinned slightly when a figure emerged from the dark.

"You finally arrived." He said and I could tell this was the real him. "I'm ready to strife." I unsheathed my sword and let my hunger overwhelm me. I am a demon, and I am in control. "Okay (Y/N), but can you tell who I really am?" He smirked as dozens of duplicates emerged from the darkness.

"Holy shit" I muttered and looked into the future. But the vision went black at the end. I gasped slightly as a sword plunged into my back.

(Time skip into the past)

"Is it him?" I smiled. The person turned around and faced me, but it wasn't him. I frowned. Where was my father? I had been about a year since I left Dave, and I really want to see him again. I have something I need to tell him. Something that can't ever be said aloud without being attacked by a nearby demon. I smiled slightly to myself, but frowned almost instantly. What if he doesn't want me to return?

-Dave's Pov-
"Hey Terezi," I said Cooly and she turned around. "H3llo D4v3" she drawled. "I was wondering if you would mind joining me on a date tonight?" I did the signature strider smirk. "Sur3" she shrugged. "I'll pick you up at 8:00. Dress casual." I kissed her on the cheek and headed home on my skateboard. "Smooth" I whispered, but I couldn't help but frown. What if (Y/N) came back. What did September 21st mean?

I shrugged it off and entered the apartment building. I hit the button for (Y/N)'s floor instead of mine. It has been a while. I guess I was hoping for signs of life in the dusty rooms, but nothing had been touched. Everything was where she has left it, even the broken glass in the bathroom had never been swept up.

I left the room and retreated to the stairs. It was time to get ready for my date.

(Time-skip 4 months later)
-Dave's Pov-
Terezi and I had been a couple for a while. She was a demon. I was a demon. It just worked. I smiled as I wrapped an arm around her shoulder to keep her warm in the winter weather. "It's time." I muttered and jumped onto the person walking past us. I dug my fangs into their neck and sucked them dry. I have begun to coup with the hunger. I feed on demons instead of humans.

-Your Pov-
I sat on the cave floor, disappointed. Nothing, just another set up. My father seemed to have disappeared.

(Time-skip present time)
-Your Pov-
Blood leaked from my chest onto the floor. "I know what you have been planning my dear." He lifted up my chin, so I was starring at him. "Make me a half-demon or that sword will go strait through the rest of your stomach." He growled and licked his lips.

How did he know? I told no one about my new discovery. No one should have known! "I know what your thinking." He smiled."How did I know? Well, I knew all along. That is your purpose. It's the very reason you were born." He hissed. I gulped. Don't give up. I heard her say to me.

"I guess the secret can die in my grave. Although you should know a red-eyed demon has been spotted. You will be rid of your ruling status in days once he takes charge." It was my turn to smirk. I pulled out my sword and dragged myself up off the floor.

"Fighting blind, huh?" He smirked. "Sure" I grimaced and held up my sword. Everything was black when I looked ahead. I couldn't see anything. I swung my sword down towards his knees and quickly sliced upward. He dodged the blow to his knees, but was sliced across the cheek from the second move.

"Not too bad. For a half-demon." He smiled and dug his claws into the wound in my chest. Pain exploded inside me and stars streaked my vision. "Bye bye." I whispered as I crumpled to the ground.

I reached behind my back and gripped the handle of my gun while he positioned his boot above my face. I fumbled with my belt, and his heel collided with my face. I heard a snap and blood gushed from my nose. I pulled out the gun, aimed, and fired.

He fell to the ground. A huge hole in his forehead leaked crimson liquid. I took a few breaths and limped out of the cave. I pulled out my phone and checked the date. It was September 21st.

I let the demon in me out which healed a majority of my wounds. I found a long shadow and melted into it. A new found ability since becoming half-demon. I emerged inside my apartment, and found everything intact. I flipped on the light switch. I had some serious dusting to do, and some shopping. I changed out of the blood splattered clothes and put on some dark skinny jeans and a (F/C) jacket.

I ran up the stairs and found myself at the door to Dave's apartment. I knocked and waited for someone to open the door.

A flustered girl I had never met swings the door open, and a shirtless Dave can be seen in the background. "Never mind..." I say before she can speak and I slam the door in her face.
