The bad girl

Edited

Mephisto' p.o.v.
"I'm so glad the Okumura's have decided to join my school, it was getting rather boring here." Mephisto said with a smirk Plastered on his face.

(Y/n)'s p.o.v.
"What, whyyyy I don't want toooo." Y/n whined.
"(Y/n) you know you have to." "Just hurry up and get it over with." Rin said with a stern look. "Ughhh Fineee!" (y/n) said as she picked up her toothbrush and brushed her teeth as did Rin and yukio. After that they said there goodnights and parted to there rooms. 'I really don't want to sleep by myself but I have to. If I want to be a awesome person like dad'  (y/n) thought to herself as she laid down and went to sleep..

        ~~~~~~dream~~~~~~~
I open my eyes to a unfamiliar setting, I was dazedconfused. I decided to walk around and see if I would have any luck finding out where I am or where my brothers were. I started walking around in every which direction calling out their names hoping for a response. "Rinnn, yuky!!!" I shouted but got no response, I wasn't expecting one but it was worth a shot right? This continued for several minutes. I was starting to worry at this point. I was ready to get up when I stumbled a cross a little girl, No older than me, maybe 6-9. I was not particularly fond of talking to strangers but at this point what other option do I have. "E-Excuses me? Can you help me find my brothers? I don't know where they could've gone so how about a little help? I asked her, hoping that they wasn't Hurt...or worse." "Yes, this way" she replied pointing in the opposite direction, and started to walk off. I knew I had no other option but to follow her, so I did. I followed her until we got into a room. This room. Why does it look so familiar? It was dark at first, practically night time, but I had no idea, i had lost all concept of time since I've been here, wherever "here" is. She slowly turned on the light. Shocked would be an understatement. There before me were two bodies that I immediately recognized as Rin and yuki, just laying there in a pool of blood, there bodys,lifeless and decaying. I gagged. "No I..this can't be it..IS THIS SOME KIND OF SICK PRANK?!? TELL ME IT IS!! TRLL ME!!!" I screamed and fell to my knees in shock and disbelief. She looked at me with sinister grin which one could say resembles the Cheshire Cat, and a pair of bloodied scissors, I slowly started to scooted away, not having the energy to stand. She started laughing maniacally and before I could react she stabbed me in the eye. I screamed out in pain and shock as blood ran down my face.

~~~~~~~~end of dream~~~~~~

No one's pov
In a moment of panic and shock (Y/n) woke up and screaming as she held her right eye. Rin and yukio woke up in an instant. Rin grabbed his sword and yukio grab his guns, both teams preparing for whatever endangered their sister. They quickly rushed to (y/n)'s room, Busting the door off its hinges.
"WHATS WORONG!?!" They shouted in unison." Now, with a bed filled with sweat and tears, the young girl ran up to her brothers and cried. She explained her dream in full detail. The boys were heavily concerned but right now they had to focus on calming (y/n) down. "Don't worry, it's just a dream with a bad girl in it, I promise you're safe no one here is going to hurt you." yukio said and picked her up and carried her to their room. "You can sleep with us tonight, ok (y/n)?" "Ok"she replied and promptly fell asleep.

Drip..drop..Drip..drop..Drip
I slowly stirred awake, I felt something...wet? Half asleep and confused, I glanced around the dark room to see if anything was out of the ordinary, as far as I could see, no nothing was. Just as I figured. But as soon as I was about to let myself drift back into slumber. I caught a slight glimpse of (y/n)'s face, and the closer I looked at it, the more blood I noticed dripping. slowly. from her right eye.
