In this world, one's eye color tells who one's soulmate(s) is/are supposed to be. Most people only have one soulmate, but having two, three, or even four has happened before. A child is born with two different colored eyes. The right eye is the child's natural eye color. The left eye is the eye color of the soulmate's natural eye color. When the soulmates meet and recognize their own eye color then their left eye will revert to the same color as the right eye. This is how it is when a person has only one soulmate. The task of identifying your soulmate becomes a bit more difficult if you have more than one. If a person has 3 soulmates, then they have 3 different colors in their left eye. However, this task is a LOT more difficult if the soulmates have all the same eye color. Let's assume this person has three soulmates all with different eye colors. If this person meets one of their soulmates and recognizes their eye color then that soulmates color will leave their left eye. A person has to be paying close attention or they may not even notice that they have met one of their soulmates. After each soulmate is found, it is usually much easier to find the next. If a person has more than one soulmate then that does not mean that their soulmates are also soulmates to one another. In fact, one's soulmates could even hate one another but they deal with one another because of their soulmate. At the very least they'd learn to tolerate one another.

Prologue

Sapphire shielded her eyes from the sun, regretting not bringing a hat with her. She looked out at the sea as the ship approached land. "England, I'm finally going to meet my cousin Ciel." She bit her lip as she looked at the other people on the ship. She felt so out of place here, all of these people were men or women with their husbands. "I'm the only girl who isn't hanging off a man's arm… and I'm the only one I know with three soulmates yet I've never met a single one of them." She sighed deeply as these thoughts filled her head. "I'm meeting my cousin today! I can't be having such negative thoughts. How old must he be now.. 16? 17? I really should just try to figure it out, it's pretty rude to ask that… when is his birthday again? It's in December right…? December… 14th! But what year…? Uncle Vincent got married in 1874… I think it's 1875… So that would make Ciel… 16! But he turns 17 in December. Alright I got this!... Or at least I hope so…" She took a deep breath and jumped when she heard the fog horn blare on the ship. "Oh we're going to be docking soon. Ciel said he'd meet me on the docks, I wonder if he is here already. Oh my god… I forgot to ask what I should be looking for… You know what, I'll just look for someone that looks like Uncle Vincent. Otherwise I'm screwed…" When the ship docked she waited for the rush of people to get off. She followed them in the much slower crowd to descend. "He should have told me to meet him in a certain place.. Or something I would recognize that we could meet under.

Sapphire noticed a tall man with black hair standing next to a boy with blue hair and an eye patch, When she noticed the boy he seemed to see her as well. She made her way past the crowd to them. "Hello, I am Sapphire Saber. It's nice to finally meet you Ciel." She smiled and gave an honorary curtsey. The small boy gave her a small smirk as he held out a hand to her.

"It's a pleasure to meet you Sapphire. And there's no need to curtsey, we're family a handshake will suffice." Ciel took her hand hand and they shook hands. "This is my butler, Sebastian. You will be staying at the manor so if you have any requests please let him know." He gestured to the tall man next to him. Sapphire had to tilt her head up to see the tall man. He was a gorgeous man, his glossy black hair, soft lips, and she froze on his eyes. "His left eye is teal…. My eye color…" The butler seemed to have realized the same thing in her left eye. He blinked and smiled warmly at her, the left eye was now red. She blushed and looked away as the red disappeared from her left eye. The green/yellow and gold remained in her left eye.

"Young Master, it looks as if a storm may be arriving soon. We should leave now to beat the storm." Sebastian announced to the two teenagers. Ciel nodded as he heard Sebastian's order and offered his arm to Sapphire. She allowed him to lead her to the carriage. She smiled to herself as she looked out the window on the ride back. They were almost to the manor when it began to sprinkle. Ciel frowned as he watched the droplets slide down the window.

"Is something wrong?" She looked at him worriedly. His attention quickly shot to her. His green eye seemed to stare into her soul.

"Sebastian has found his soulmate, is it you? Your left eye hasn't returned to normal yet I don't see any red in it anymore." He didn't sound accusatory, he just sounded confused.

"Yes, I am his soulmate… but my eye will not revert until I meet my other two soulmates…" She rubbed her neck nervously.

"You have three soulmates? Well then… that's interesting, I didn't think I'd ever meet someone who had more than one, I just thought your soulmate had a very unique eye color." Ciel explained, Sapphire giggled.

"It would be very interesting to meet someone with an eye like this." She gestured to her left eye. The carriage slowed to a stop in front of the mansion and Sebastian opened the door. Ciel hopped out and Sebastian held Sapphire's hand as he helped her down, before he let go he gave her hand a gentle squeeze. She blushed a soft red and followed Ciel into the mansion. "Wow…." She could only look around with wide eyes after she entered. "This mansion is gorgeous…"

"It should be, Sebastian has very strict orders to make this place presentable." Ciel commented dryly. "Sebastian, give Sapphire a tour of the manor. Bring me tea in my office when you're done." Ciel walked up the stairs and disappeared in the hallway to the right.

"As you wish, my lord." Sebastian bowed and smiled at Sapphire. "Is there anything you'd like to see first, my lady?"

"Oh um just Sapphire is fine!" She blushed as he stared at her smirking. "Can you show me to the library first?"

"As you wish, Sapphire." Sebastian's voice made her heart pound in her chest. "Please, follow me." She nodded and quickly followed the butler. He first led her to the library before giving her a tour of the rest of the mansion. "And this is your room. There is an attached bathroom so when you want to bathe, please tell me and I will send Mey-Rin to assist you." He smiled at her before it quickly changed into a smirk. "Or if you'd prefer I could assist you."

"N-no that's fine…" She fanned her red cheeks as her imagination went crazy.

"Well, this is the end of the tour, do you have any questions?" Sebastian watched each expression she made with amusement.

"No questions. But I do have something to tell you. Well, two somethings." She corrected herself as he chuckled.

"Alright, and I have something to tell you as well." He looked at her seriously and she swallowed nervously. She stepped into the room.

"Then how about we talk inside here?" She smiled nervously. Sebastian nodded and stepped inside her room.

She sat on the loveseat in her room and sighed softly. "Okay… so I'm sure you've already noticed that my left eye hasn't reverted. I have more than one soulmate… I actually have three. I only know of you though…" She approached the subject carefully. His eyes narrowed dangerously and he began walking toward her.

"Well then, that makes my confession a lot more difficult." He leans over her, trapping her between him and the couch. "I am a demon… and I do not share." He growled. Sapphire could only stare up at him in fear.

"T-that's not really up to you.." She spoke softly, trying to keep herself calm. "A-also I said I had two things to tell you." Her voice got stronger as she got more confident. "I am a witch." She declared. "And I would suggest you let me find my other soulmates or else I will not be happy." She threatened and he sighed heavily. A good relationship between soulmates meant that all soulmates have to be happy with each other.

"Fine then, but remember, you are here as a guest of the Phantomhives. It would be quite troublesome for the master if you were to be seen with multiple men. " His tone was sharp, but he did not seem as threatening as before.

"One of them is you, you know." She rolled her eyes and he nodded.

"I know, and at least that thought pleases me." He stepped back, releasing her from the sudden imprisonment. "And a witch? Interesting. What kind of witch are you?"

"I am a meteorological witch. I can draw energy from weather events and can cause them. So make me mad and I have the power to suck you into a tornado or shock you with lightning." She grinned innocently and he chuckled.

"Very well, I will take care to not anger you then." He smiled at her softly. She blushed again and he bowed to her. "I must go make young master's tea now, do you need anything before I go?"

"No, I'm fine." She smiled at him and he left.
