Soul War (G!sans x Nephalem Shifter Reader)

Chapter 18:A Nephalem Shifter?

(G!sans POV)
"Hey Asriel what the heck happened here and who is this guy?!" "Well I was about to tell (Y/N) that it makes me mad when I see her look at you the...........never mind well this guy attacked us and then out of nowhere try's and seduce (Y/N) also forcefully kissing her!" "I'm gonna have a talk with you after about (Y/N) but right now let's focus on this guys" I summon two Gasterbasters firing at him. "Tina my child take Lily with you inside and hide and don't come out of the castle until we say so ok!" "Yes Toriel" Tina grabs Lily's hand and quickly rushes inside. "Heh you really think these little things will hurt me?" The smoke clears and we look to see that it has only take a tiny bit of his Hp. "Man you guys really are stupid, anyways hand over the lovey lady and I just might spare you all" "Like hell we'll let you take  (Y/N) from us! Who are you and why do you want
(Y/N)?" "oh so that's the lovelys name" "My name is Lucifer and my group has been looking for something to train with but after looking at her I think I'll just keep her to myself and have fun with her if you know what I mean" this motherfucker makes a perverted smirk then licks his lips. This really hits a nerve in Asriel, he then swings at Lucifer. He blocks it with one arm. "Oh did I hit a nerve goat boy?" This guys then uses a spell with his spare hand punches Asriel it the stomach. Asriel coughs blood .The others jump in and fight Lucifer now. "Guys move now!" I set off ten Gasterbasters on him and begin to fight with hand to hand combat. "So she your girl huh. Tell me she your girl then why do you and goat boy act so sensitive when you hear that?" I punch him with no mercy making his nose bleed. "Don't tell!?" Lucifer looks confuse and about to laugh. "You haven't fucked her!? Man you really are a pussy!" "For your info Lucifer I have fuck her and she enjoyed every last bit of it" I say proudly. "SANS YOU DID WHAT!" Lucifer is then hit by a beam of energy knocking him down. I look up to see her again. "It's her! Papyrus the demon angle from before!" She flys gracefully onto the ground, she's dressed complete in black and is wearing a mask. "What the hell, who did that!" Lucifer look in her direction wiping blood off his mouth. "The Nephalem Shifter?" She walks to him and picks him up by his shirt. She then turns to look at us all
"!NEPPAH DLOUC TSROW ESLE RO REHTO OT EM FO NOITEM TON DNA ECNETSIXE YM FO TEGROF LLA LLIW UOY" she says something I can't really spell out then snaps her fingers every thing goes white. I open my eyes "where's the demon chick and dude!" Undyne yell, she was right they both vanished out of thine air. Where'd she go?

(Y/N POV)
I teleport me and this back to the dark souls. "Yo let me go!" I throw as hard but not hard enough to kill him. "Ow what the fuck bitch!" I spoke to him so he would understand "Listen here you will leave those monsters alone if you know what's good for you and your team mates!Well cause if you do go near them or that girl again heh" my eyes begin to glow really bright as I show my fangs "I'll make your life a living hell!" He quickly back away, Pathetic! And with that I teleported back to Where I had left Alphys.

(Time skip to palace)
"(Y-Y/N) you're back w-what happen d-did you get rid of him?" I change back to normal form, I immediately fall to the floor. "(Y/N) are are you ok?" "Don't worry I took care of him, dam it I shouldn't have transformed without my power rings." Kinda of shaking I slowly get up. G quickly rushes in. "(Y/N)!"
"Yo (Y/N) Are you ok?" Leo shouts coming after him "Did he hurt you my child? what happen?" "It's ok you guys I'm f-fine" I feel myself weak then falling over, the last thing I see is G rushing to me with fear in his eyes.

(G!sans POV)
I immediately catch her before she hit the floor. "Alphys what's wrong with her?" "I-I don't really know, what w-was that t-thing again?" "Um a demon human" "did it do anything to her" " yeah he kissed her!" Asriel butts in. "Oh she'll be o-ok she just n-needs some rest, that thing took some of her energy that's why she collapsed" "She can rest in our guest room for you all, I believe she's sharing rooms with you Sans, will you take her there to rest please?" I pick her up bridal style "sure Toriel. See you guys in the morning" I teleport too our room. I put her on the bed I change into a t-shirt and black jeans. I then walk to her I take off her shoes, wipe off her makeup and undo her hair, she's just like a doll. I grab a baggy t-shirt from her bag . I start blushing, I just realized I have to undress her. I take of her sleeves and side on the t-shirt. After u slide the rest of the dress off and put it to the side. Since when did
(Y/N) have a tattoo on her back? It's pretty interesting, an angle wing with a demon wing. I tuk her in bed. I jump in with her, she has a cut on her cheek. I lick the blood off. It begins to heal then close up. I Hug her. Who is that girl and why does she feel so familiar. I'll have to try to figure out what she was saying. *Yawn* I gently kiss (Y/N)'s forehead. I'll do my research on her in the morning. Good night love.
