~Your P.O.V~

Sebastian stared at us for what seemed like hours, he was shocked, what? I had a sister, is that a problem?

"May I come in?" Ariana asked, I realized she was still outside.

"Oh! Sorry Ari." I said, She rolled her eyes from the nickname I called her, I chuckled a  bit as she walked into the manor. 

"The young master will be here shortly." Sebastian said smiling, she smiled back then went up to Sebastian.

"By the way, if you hurt my sister, I don't mind killing you, Im the special sister after all." She said. He looked up at me, I whistled and tried to leave the room, Sebastian grabbed my shirt and turned me towards him.

"Explain." He said smiling, I sighed and got over the fact that I couldnt run away from this situation.

"Welllll..." I began, "My mother wasn't exactly fully humannnn..." I said letting out a small laugh of nervousness, he raised an eyebrow, he turned to Ariana.

"She was a grim reaper as well." She finished off, I felt Sebastian's eyes widen as he heard those words come out of her mouth. She smiled and brought out two daggers.

"I became a bit of a demon and a reaper, as for her she became a demon and a human, but she is more of a demon than me, I am half/half." She explained to him.

"Your family is a bit odd." Sebastian said while letting out a small laugh.

"You think?" I said, dusting off my (f/c) skirt. I then heard the main doors open, Ciel walked in with a happy Lizzy. He looked up at us, then Ariana.

"Welcome home, my lord." We said at the same time, Ariana just stood there, smiling her lil ass off.

"Who is that?" Ciel asked, he went closer to Ariana, they were a few inches away, I felt Lizzy get jealous, I grabbed her wrist, giving her a look.

"You dont remember me?" She said, Ciel made a 'hmph' sound and crossed his arms.

"What the devil are you playing at?" He said, a bit annoyed. He looked back at Ariana's grinning face.

"Now what was that nickname you gave me? Oh!" She paused, bring a devious smirk across her face. " Yujin" She said.(Yujin means friend in japanese btw) Ciel dropped his arms slowly to his sides, his eyes widened as he began to come closer to her.

"Yujin?" Ciel asked, as if a question, he hugged Ariana. Sebastian and I looked at him shocked. We both had our eyes wide, the other servants came in as their eyes also widened. Lizzy was full of jealousy, she escaped my grip and ran to Ciel. She tugged him into her arms and looked at Ariana.

"I dont care who you are, but stay away from my beloved Ciel!" Lizzy said, she held onto Ciel with great force. Sebastian went next to me and held my waist, I looked at him as he smirked and put his chin on the top of my head, I blushed a bit as I turned back.

"Lizzy...Let go." Ciel said, he was looking at the ground, not paying attention, he really liked Ariana, they seemed to be good friends.

"But Ciel!" Lizzy said, hugging Ciel even more.

"I didnt even start the hug, I just hugged back." Ariana said coming closer to Ciel and Lizzy. Lizzy went into defense mode and backed Ciel away from her.

"Yujin..." Ciel said. They had a great bond. They knew what each other wanted. One look, One word and they understood. Like me and Sebastian in a way.

"I think Ciel has a stronger bond with her then with you." I said, he smirked and let out a small thing of laughter.

"I dont mind...I have you after all." Sebastian said, I blushed a bit. I then made a 'tch' sound and continued to watch the small fight.

"Got it." Ariana said, she came closer, she looked awfully scary to be honest. Lizzy was full of fear, but she still tried to protect Ciel from her. Ariana grabbed Ciel easily and placed him next to her. Lizzy's eyes were wide as she watched.

"C-Ciel.." Lizzy said, she was confused, I could tell. Yet, Ariana and Ciel seemed to enjoy it, those evil little shits. Lizzy adjusted herself and walked towards the door, Paula right behind her.

"I will come back." Lizzy said in a stern voice, I was a bit shocked on how rare Lizzy was actually serious, I loved when I saw her be all serious, it made her should much better.

"Why are you here anyway?" Ciel asked, looking at Ariana, she smiled and put her hands on her hips.

"I wanted to visit you, since I found who you were, also I wanted to visit my big sister!" She pointed to me, Sebastian still wrapped around me, I blushed a bit as she hid a small squeal, seeing how Sebastian was placed. I let out a small wave of nervousness and a crooked smile.

"How interesting...Sisters huh?" Ciel said looking between me and Ariana, he seemed a bit confused, but after awhile he got the gist. 

"You two kind of look alike anyway." Ciel finally agreed as me and Ariana looked at each other. We smiled and let out a short period of laughter. 

"Will you be retiring here Yujin?" Ciel said, he almost let out a small smile but quickly stopped himself before he could.

"May I?" She asked with a small smile. Ciel nodded and went up the stairs.

"Would you like your own room?" Ciel started to say, he then saw how Ariana had her hands to her hips, giving him the 'you should know by now' face. He let out a small thing of laughter and rolled his eyes. 

"She will retire in my room tonight. So do not prepare a room." Ciel said looking at me and Sebastian before walking off with Ari. I turned to see Sebastian, still holding onto me. I felt his grip go a bit tighter, I tilted my head in confusion.

"What is it?" I tilted my head in confusion, Sebastian smirked.

"I have never seen the young master like someone that much in my life." Sebastian looked up to where Ciel was talking to Ari. He sighed and laughed a small bit. He looked back at me, he stopped laughing but kept a sweet smile plastered along his face. He bent down to my side and gave me a kiss. It wasn't another quick kiss, he seemed so off lately, I smiled a bit. He glared at me. 

"You dont usually smile like that, it makes me...happy...?" Sebastian said, it sounded like a question, like he didnt know what it meant to be happy so he had to check. My smile dropped as I looked at his face. I tippy toed up to his face and gave him a quick kiss. He seemed very shock from my doing. I smiled, putting my hands to my hips and walked away. I started to walk as I felt something wrap around my waist, I saw Sebastian's arm, I looked back to be instantly kissed by him, he pulled back as he smirk, giving me a quick kiss on the neck, I blushed massively as I looked down at the floor. Damn this guy.
