Nightmare's  P.O.V.

I was roaming around my castle attempting to find something to do while the others were out destroying AUs, and most likely fighting the Star Sanses. I strolled into my throne room, but instead of immediately sitting, as I usually do, I stared at the grayish, red ball of fur sitting on my seat. I teleported next to my throne and stared in shock at the fur ball. The small beast had a skull like face and had horns where its ears would 'normally' be. It was small, but much bigger than a full grown chihuahua.

The little beast started to stir in its sleep, or what I presume is it's sleep, and then had these small, dark red eye lights appear. It looked at me and yipped. It then started to get up and shook its fur and face around. "What are you? You're definitely not a Gaster Blaster, nor are you a normal dog. What in the AUs could you be?" I questioned, though I knew it could not answer me. It then yipped at me again and started to climb the armrest of my throne. "GET DOWN." I said, glaring at the small creature.

It then began to whimper in, what I believe is fear, and got down. Now that it is standing I could see more of it. It happened to be a she and she had a long, bone tail with a tad bit of fur near the beginning of the tail. She had a collar on her neck, as well as a tag. "Y/N the hellhound." I read aloud. I then quickly looked to the back for an owner, but there didn't seem to be one. I then looked back at the cre-hellhound and saw her looking at me curiously.

"Hey boss. We're back." I heard Dust call from the hall behind me. "And was your mission successful?" I said, turning around to face him, only to be greeted with a psychopathic grin and his deviously shining eye lights. "Of course it was. Underlust was easily destroyed and the Star Sanses fled." Dust's face held such a chaotic look to it, but it was nothing compared to his expression in battle. "Good. You can leave now, but be back here by 7:00. I'll have your new mission then, understood?" Dust nodded his head and walked off, not paying any attention to the fur ball that hopped off of his Boss' throne.

"Now, where was I?" I said, dropping onto my knees. Y/N barked at me and started to nuzzle me with her small skull, though she did get some of my goop on her. 

Y/N then started to bark again and ran off. I could hear the loud, clicking of her claws on the black marble floor. I chuckled and began to chase after her. She is quite fast for a pup, but I could still catch up to her. She then took an extremely sharp turn and I ended up running into a wall, but I luckily didn't hurt anything major, nor did I knock anything over. She slowly walked back over to me with her head down, and was whimpering. I pet her skull, trying to show her that everything was alright. She leaned into the my hand and began to nuzzle it. I chuckled at her behavior and picked her up. This caused her to yelp in surprise, but she stayed quite still. 

"I believe I will be keeping you for a while, now won't I?" I said, looking down at her. Her blood red orbs looked back at me and her skull held, what I would like to think is a grin, on it. 

(I'm sorry, I had to put this adorable face on there. I'm also sorry it's so short.... I had a great idea, but I lost it halfway through the story. I'm so sorry.... I hope you enjoyed this chapter!)
