{Old} A Change In Nature (Nightmare!Sans x Reader)

Chap. 4: The Tour

(Again, warning for (censored)cursing.)

(Y/n)'s POV:

I watched as Nightmare stormed off, seemingly irritated at the two skeletons that he was dragging. Both seemed to have a shit eating grin on their faces as the one with the black dripping from his eyes quickly piped up, "See ya later newbie!" I heard Cross sigh mumbling something that I couldn't quite catch.

"Come on, I'll show you around. Don't mind Dusty(Murder Sans' nickname), he won't bother you anymore." Shiva gave out a huff in my arms. I swear that she can be so much like a human sometimes, especially with her attitude. I didn't realize that Cross was staring at my cat till he had walked up and asked, "She... wouldn't bite me would she?" his hand hesitantly hovering towards Shiva.

"Not if you allow her to become familiar with you first." I replied, smiling gently as I led his hand for her to sniff. A large smile broke across his face when she liked one of his phalanges, giving him the 'okay' to pet her. I swore that I heard a young child's voice giggling as he pet the loudly purring cat in my arms.

"Wow Cross, I didn't think that you were a cat person. I would've thought that you would be a dog person with how many dogs you knew." Cross visibly stiffened at the comment. My face scrunched in confusion when I saw an ethereal figure of a child hovering beside Cross, a snarky smirk stretched their lips in a mischievous way.

I sighed an agitated breath replying to their remark with, "Well I don't see anything wrong with liking cats. So maybe he's had more experience with dogs than cats, so what. That doesn't automatically make him a dog person, er, skeleton. He can like whatever he wants... Um... is something wrong?" You started getting nervous as both of them started to stare at you in a mix of confusion, shock, and a little bit of anger from the boy.

Cross' POV:

"You... can see them? How? I thought that I was the only one." I asked intrigued, the last sentence being mumbled. "Oh, yay! Another one." Chara spat sarcastically, (Y/n)'s frown deepening.

She rolled her eyes and decided to answer my question instead of argueing with Chara. "Yes, I can see them. Am I... not supposed to?" She seemed to be a bit concerned as she asked in return.

"Not necessarily, no. you're the only other person, other than Cross of course, that can even hear me let alone see me. Look Cross! You've got a 'crazy' buddy now!" Chara mocked.

(Y/n) gave them a 'really' look and snipped back. "Wow, you're even more childish than Murder Sans. What are you, a five year old?" I snorted at the comeback while Chara grumbled.

"HEY!! WHO THE F^&% ARE YOU B*$#@S CALLING CHILDISH!!" I snorted, trying to hold in my laughter. I had completely forgotten that Dusty was still standing there, and from the visible cringes, Chara and (Y/n) had forgot as well.

(Y/n)'s POV:

I... had completely forgotten that Murder Sans was still standing there. I had whipped my head around to see and..., Oh no. He was fuming. His left eye was glowing with a flame like purple, a new sharpened bone in his clutches. Turns out I had unknowingly mumbled that 'Oh no' and Cross had quickly grabbed my hand, turned around, and ran.

We both took off sprinting as fast as our legs could take us, Murder being hot on our tails. When Murder started to throw his attacks our way, I decided to pull out my bowie knife and knocked a few to the side to protect our backs. Cross seemed to blink in surprise as he summoned an enormous red glowing knife, tearing open a portal and quickly closing it behind us. Cross took the both of us to a bedroom as we huffed and wheezed in exhaustion, trying to regain our breath from running for our lives.

I don't know why, but when I regained control of my rapid breath, I suddenly started to laugh. A few seconds later, Cross joined in and we started to laugh almost hysterically, our adrenalin still fueling our bodies with energy. As our laughter started to simmer down, Cross asked, "Heheh, I never noticed that you had a knife on you. Where did a human like you learn to move like that?"

I couldn't help but smirk at his awe filled gaze, being filled with a little confidence. "I taught myself." As I came down from your adrenalin high, I started to remember the reason why I'd learned how as I continued, my taking on a sadder tone. "Where I'm from, sometimes you have to give quite a fight just to get some food."(In your world, you were one of the lucky ones who managed to get to 'safe haven'(the part of the planet NOT in a state of purge) which is why you have the hobby of blacksmithery. You had to make your own weapons in order to protect yourself.)

Cross seemed to catch onto the fact of it being a sensitive topic and didn't ask any further; Chara didn't either.

(Time skip to a few months later and adjusting your new room 'cause Sheinria is lazy(I'll be referring to myself as Sheinria from here on out by the way.).)

Cross had decided to help me feel more at home by helping me adjust my room. After we had gotten more acquainted, we decided to be brother and sister because of our similar experiences of losing loved ones and no longer having any more family left. Though it may not technically be 'official' but we're comfortable with it as it is.

Though, just as Cross and I were applying the final touches, there was a knock on the door. Cross and I looked at each other and then the door, both of us contemplating whether to risk it being Murder Sans or to simply ignore it. Just as Cross had grabbed a chair to block the door, Nightmare's voice filtered through the door.

"Cross, you didn't piss off Murder again did you?" I snorted at the exasperation in Nightmare's tone as he said 'again'. "Pffft! Again?" I replied. I heard Nightmare from the other side of the door before Cross decided to reply. "Actually, as much as I'd love to take the credit, it was actually (Y/n) here that had done so."

Nightmare seemed to be taken back a little at the fact and it took a few seconds to say anything further. "Huh,... interesting. Am I allowed to come in?" he asked. But as he finished his sentence, Cross had already opened the door. "Now, if you don't mind, I would like to show you something (Y/n)." he said, offering his hand once more.

(Phew, finally done with this chapter! It ended up much longer than I had anticipated, but that's a good thing! Right? Anywho, hope you liked this chapter and I'll get to the next chapter as soon as I can. Write to you next time!)

(Adding a touch of a change to make it to where the later chapters make a little more sense. if you can't figure out what the change is, it's this part... ("Time skip to a few months later and adjusting your new room 'cause Sheinria is lazy"))
