Title: Lucifer's Lovely Sister

Summary:"I'm most likely the most amazing person born on earth. I don't think I can properly convey my awesomeness. Get to know me, and you'll find out just how great I am. JK, don't do that. I already have enough attention whores in my life." -Sienna Satan (Yes, that Satan.) Female OC x Sebastian.

Bleh. Very cheesy, but I'm too lazy to change it.

Rating: K+

Does mention demons, but what do you expect? The show is about a boy with a contract to a demon. If you don't like, don't read.

I'm sorry if you actually had to read the unedited versions. Those were horrible. Please enjoy this chapter! Also, I may be a little slow on updating, editing, and revising this story since I started a new one...but since when am I not?

The atmosphere in the study was awkward. The young earl shifted anxiously in his chair. The tension in the air was unfamiliar and definitely unwelcome.

Sienna stood at attention directly in front of the large desk. Her lips curved down as she observed how uncomfortable Ciel was. If he was always this fidgety, he must have trouble sleeping. She once read in an article that children who slept less were more grouchy than one who had more sleep. That would explain a lot, she decided.

He was much too strict and serious for someone of his age. Such a youngster should be playing video games and feeling mad when they lose, because most kids were pretty terrible... except Matt. Unfortunately, video games were nonexistent, so playing with them was not an option. What was an option was sitting awkwardly in a room with a human, a soul-eating demon, and a celestial being.

Sebastian was waiting patiently at the door as a loyal butler was supposed to but he was more on edge than normal, Ciel noticed.

"Does my presence make you uncomfortable, Buddy?"

"Not at all" The black-clad man replied smoothly, though his eyes narrowed at the new nickname.

"Aww," She coos, "Is the little demon irritated?"

Sebastian's eyes flash a bright pink for a moment. He smiles his closed-eye smile.

"Of course not. I apologize if I wrongly conveyed my emotions, that is unacceptable as a representative of the Phantomhive Estate."

She looked at him with a "really" face.

Ciel watches, amused. The boy did not know her origins, nor her intentions, though they seemed to be innocent.

A calculating look enters Ciel's eyes. Eye, if she were to be technically correct. The look was similar to one she often wore in the past, the past being just a few hours ago.

Iris would always joke that an angel from heaven would scold her when she misbehaved. She was way too young to realize how weird it was to say something like that, but it stopped her from acting out.

Sebastian poured tea carefully, ensuring none was splashed on his young master.

Ciel nodded in approval, immediately recognizing the delectable aroma. His cup clattered as he raised it, his movements a blur.

It was quite hot outside, Sienna noticed, but she figured it was probably just because he was a twig, tiny and thin.

The boy downed the tea in one go, which, should she mention, was very impolite with company over.

At least he stopped shaking. The tea did its job well, warming him up.

As of then, he was officially stressed. He had grown accustomed to it, but this time felt different. Was he afraid? No, he'd order Sebastian to take care of her if he was. Intimidated? Yes, that sounded about right. He was not afraid. Not of her. Fear and intimidation were worlds apart.

Never in Sienna's life had she been able to so easily read someone. Not even when that one guy was killed by the angel. And his wife. Wasn't that only a few years ago if you took the year change into consideration?

Wait a minute...This guy was the Ciel Phantomhive. She thought he was like, Ciel Phantomhive III. She'd say Ciel Phantomhive Jr., but III seemed to suit his prissy attitude better.

Finny burst in, twigs and leaves stuck in his hair "Sebastian, come quick!"

Annoyed, he did as told.

Ciel closed his eyes and leaned back, glad for the moment of peace.

"Awww, you forgot about me already?" His eyes snap open. "I'm heart-broken"

That's right. Sienna, she introduced. He seemed to be extra forgetful today. If he had a choice he would ignore the girl, but her antics were too distracting.

She stretched lazily on the cushioned chair. It was awfully comfortable. A wide smile formed on her face.

"So, Ciel Phantomhive, what's up?"

He frowns "Pardon me?"

"Never mind."Sienna sighed."I forgot you wouldn't understand me. It's beyond your limited to nonexistent knowledge of modern slang. I didn't realize that it was even slang before now. Isn't it just a metaphor? You'd have thought ya'll would know what that is because Shakespeare already came along"

Ciel's brow furrowed, not understanding anything she was trying to say. Annoyed, he complained that she needed to speak clearly.

"Whatever." She rolled her eyes."Would you like to strike a deal?" at his raised brow, she clarified further "For information. Maybe involving a simple game of chess"

Sienna recognized the spark in his eye. He thought he would win. Silly humans. He seemed to have the ridiculous notion that he was invincible simply because he hadn't met a worthy opponent. Well, reality was going to hit him real hard in the future if it continued. She couldn't just let that happen.

"If I win, I get to stay here and get free reign of the... I lose, I'll tell you whatever you want to know"

"If you win, you get free reign of the house, excluding my bed chambers," Ciel added, to which Sienna agreed.

As they set up the board, she grabbed for white, eagerly placing them in their correct positions.

Sienna reached toward one of her own chess pieces. "Game on."

Hopefull,y this chapter is better. Before editing, it was around 2,000 words long, and now it's down to about 900. Most of the parts deleted were just unneeded dialogue, cheesy lines, and other things that I don't want in this story now that I know the characters better.

In my opinion, the first chapters are always the hardest to write because you don't truly know your character that early in the story. It took me longer than expected to find out more about mine, but it is what it is.

Also...I'm learning Japanese. I'm a beginner, but I know basic phrases, hiragana (working on katakana), some basic adjectives, word particles, random vocab, useful vocab, kanji radicals, and some kanji. Tell me if you need a study buddy! (P.S. WaniKani is very useful, so I suggest using it!)
