Black Butler x Reader One Shots

Sebastian

Looking over the maid, you almost pitied the poor mortal. Being in love, but not being loved back. Being a demon, you can't say you felt the feeling of love ever. Sure you have the same soulmate sign as human, but after being alive for centuries and not seeing colors you've given up. This contract will be easy to complete. Smirking at the maid's nervous watch, you leaned towards her.
"You know if you make this deal with me, heaven will forever be out of your reach and your soul will be devoured by me in the end, yes?" You reminded her, watching her visibly gulp, but nod.

"I know that, yes I do." the maid squeaked, as you held your hand out with a grin. When she shook your hand, she groaned in pain as your contract mark burned onto her hand. Tears swelling in her eyes, before you let her hand go. The contract complete.

"Okay, now, can you tell me who this human is that gained your affection?" You questioned.

"He's the head servant of the Phantomhive estate, Sebastian." She whimpered. You already had a plan forming in your head as you changed your clothes to match her maid one.

"Then if you can get me to work with you in the manor,  it will make things easier. I can plot and make more connections for you two." You explained with a grin, " You can introduce me and tell them that I am a friend who is looking for a job."

"That's a good plan, but what is your name?" She questioned seeming confused.

"That is for you to decide." You explained, watching her think.

"You're name will be (Y/N), it will." She decided, opening the door to her small room. Leading you into the rest of the manor. Looking around, you frowned when you felt the presence of another demon's power in the building. This might be a little harder with another demon here, but so long as the two of you can come to an agreement, then there wouldn't be a problem. 

Reaching what you assume was the entrance to the manor, you went tense when the demonic power increased.

"Mey-Rin, who is that?" A voice called, making you look up the stairs at the butler. Blinking as your eyes suddenly had to adjust to the burst of colors. His red eyes widened slightly, as he scanned you.

"This is (Y/N). A friend of mine who is looking for a job." she explained, "(Y/N), this is Sebastian." 

Oh no, he is the one she likes. You doubt she knows he's a demon, but that's the least of your problems. How are you going to complete this contract when the one she wants you to set her up with is your soulmate? Trying to remember you were under a contract, you bowed slightly.

"I would very much like to work here if possible." You explained, feeling his power surge. Showing that he was clearly stronger than you.

"I believe you would be a good asset to the Phantomhive manor, (Y/N)." He hummed holding his hand out to you. This contract just got harder.
