Your best friend was standing there at the door "KAY!!!" You screamed and hugged her ( that's right I'm in the story I'm sorry I couldn't resist) " I missed you so much" she says
Sebastian's POV
I knew this girl wasn't human from the start she was a demon just a higher class HIGHER THAN GRELL AND WILL. I know her she's the boss of all of us I forgot she can shape shift... Suddenly "SEBASTIAN" ciel called "please excuse me the master needs me" he said then walked away
Your POV
You walked Kay up to you room and you both sat on your bed and talked she asked how you got in the phantomhive manor you explained everything you knew she wasn't human same with Sebastian but you didn't care you knew neither of them would hurt you "so Kay what do you think about Sebastian?" You say "he's a demon" she said "with out a doubt, I know him"
~time skip~
So you were sitting at the table waiting for dinner to be served ciel kept looking at Kay I wonder if he knows soon sebastian came out with the food Kay was still in her other form her human one she had blue green eyes with black hair their was a strip of blue in it that would never go away no matter how many times she would shape sift the blue would still be there except in her demon form finally ciel said something "what are you, lady Kay" "why I'm just a human" she replied with a smile she never smiled only in her human form " lady Kay, I do believe your a demon more or less a monster" said Sebastian "OKAY,FINE YOU CAUGHT ME" Kay screamed ciel had a look of confusion on his face "I can also time travel I went to the 21 century and I live there for a couple years but ever since I came back I realized everything was different y/n was older and her parents died and she ran away so I came looking for her" she explained "I thought she was on the streets but then I realized I could pick up her scent and I found her here" after awhile of explaining Sebastian asked to see her true form "gladly" she said Kay stood up and a whole bunch of arrows wrapped around her body her eyes went red and her hair turned completely black her black sword appeared in her hand it was all black with a blue arrow on it she wore a sweat shirt that was black with arrows on the hood of it she had a short skirt on with black ripped leggings and boots up to her knees the heals weren't straight they were sharp the boots had arrows on the side of them both black her teeth grew sharp she also had a snake tattoo on her wrist and her eyes became narrow like a cats eye still red "you know I kinda like this form better than any of my others" she said as she put her hood up on her hoodie ciel kept staringat her.
Ciels POV
Kay changed into a demon he has never seen anyone like her... Demon wise he tried to figure out what she was she wasn't like Sebastian and not like Claude he was a spider. "Ciel, darling I'm a snake" she said "WAIT YOU CAN READ MY MIND" he almost yelled as loud as possible " of course I can if I couldn't what kind of demon would I be" she said with a slight smile than walked to her room which was right by y/n.
