The Skeleton Siblings Four (An UnderFell Story)

Her Inner Demon

((The pic above is someone you will meet soon but here is a hint. You two have already met =) ))

(Bk to your pov)

It was dark. I couldn't see. I flared up my eye and a could make out a skeleton girl. "Calli?" I questioned. The girl didn't reply. "Sis is that you?" I asked.

The girl turned around. She had red hair with 3 streaks, yellow, green, and blue. Her right eye was replaced with a hole. It looked as if it was more of a crack.

She had a smoky blue, green, and tan shirt with a smoked red overshirt. She had grey and purple leggings and blood red boots. She had midnight purplish blue demon wings.

Her eye flashed red and blue and her hand flew a dangerous purple. A spear formed. I was too scared to move. All at once, she struck at me.

I woke with a scream that could send a frozen person's blood to a boil. Calli, who was in the same room with me, fell out of her bed at the far side of our room with a screech. A vision of the girl flashed before my eyes and I backed into a corner. I curled into a ball and cried softly.

Calli must've heard my cries because I felt her pick me up and hold me close in her fluffy wings.
"(Y/N)? Hey what's wrong Flutter?" She said in a sad voice. Flutter was the nickname she gave me .

I hiccupped and stuttered, "i-I ha-had a ni-nightm-mare-re..." Calli hugged me. "Wanna tell me about it?" She asked. I nodded.

I told her exactly what happened with the girl and me. "Wait what did the girl look like?" She asked. I told her and her one visible eye turned dark. "Tha-That... S-She... I-I'm... Th-The girl... h-how is she back?" She stuttered.

I tilted my head. "You know her?" I asked. "Sister... that girl... is... me... My inner demon..." Calli sighed.
