Living in the mansion seemed to heighten Yui's hearing considerably since she was always afraid of one of the guys sneaking up on her. It didn't take much to frighten her either. Often times she was startled by the slightest sounds.

It was the sound of her door easing shut that had her eyes pop open that night.

Her heart was already racing. Who had just been in her room?

Somehow, the air felt heavier and the smell that wafted through it was different.

A vampire's scent.

They all had one, Yui decided as she sat up and gave herself a quick inspection. But she knew Ayato's scent much better than the others. It was something dark and alluring all the same. It frightened her, as well as enticed the better half of her curiosity to know him better.

The one that lingered in her bedroom air did not belong to him.

Yui rose from her bed to lock her door again. Before doing so, she carefully opened it and peeked outside. She was met with a desolate hallway. The darkness began to scare her so she closed it.

"Were you looking for me, little bitch?"

She froze at the voice behind her.

Laito.

Yui slowly faced him.

"I- I thought I heard something," she answered.

He was standing on the side of her bed with this hands in his pockets. His back was facing her balcony where the only light of the moon slipped through. His eyes seemed to be glowing like that of a cat.

He was hungry.

He rolled his eyes and made small strides toward her bed. "Well, this is an old mansion," he said, pulling a fistful of rose petals out of his coat. He tossed them carelessly over her sheets. "You will hear many noises in the night. The next I hope to create, is the sound of you and I making passionate love together."

Yui kept her hand on the doorknob behind her. She tried her best to control the sickness that trapped itself in her throat.

Laito stopped in mid-grin and frowned.

"What's wrong? I thought the little bitch would be happy that I will be the very first to have you in every way. So come on, let us enjoy ourselves." His smile revealed his devilish fangs.

Yui bolted from the bedroom into the hall. She didn't know where she was running, but her legs knew to take her in the direction of the moonlight. However, before she could reach the end of the hall, Laito materialized in front of her and grabbed her wrist.

"I love a good chase, little bitch," he said humorously and brought her hand to his lips. She felt his other hand trailing the edges of her nightgown and then begin to lift it away.

When she felt his cold fingers skim across her thigh, Yui found the strength to wrench herself from him and race toward the other end of the hall, into the complete darkness, which probably terrified her much more than Laito now.

She closed her eyes since she couldn't make out anything else but the walls, only opening them in spots where there were windows, where the moon could show her the way to safety.

She gave a small scream when someone reached out and yanked her into a room.

A hand immediately went to cover her mouth.

It was a tall man, whose body was so close, she could smell him. She recognized the scent though. It was the one she found in her bedroom not long ago.

"Be quiet, or I'll let Laito have you," he said calmly. "Understand?"

Yui nodded and he took his hand away and stepped back.

"Here, take my hand," he said. "Stop trembling. I just want to see you."

She had no idea which room she was in, nor the way out. She didn't have much of a choice. Cautiously, Yui reached out her hand.

The mysterious vampire gently took it and began to lead her through the pitch blackness of the room. So he knows the place, Yui thought. But who was he, and why was he here?

He led them to another door. She heard him open it and suddenly, the shimmering moonlight filled her vision. She could see his back as he walked in front of her. Although it faced her, he was remarkably built.

The back of his head presented dark black hair with silver tips. He led her to a window where the moon seemed to shine the brightest and faced her.

His unnatural beauty astounded her. His choppy locks framed deep grey-set eyes that seemed to smile strangely at her. He wore a simple black V-neck with a grey blazer and a smirk that Yui couldn't decipher.

"I would have waited until tomorrow. But since you're awake...It's Yui, isn't it?"

"Yes. Who are you?"

"When I'm ready to give you that information, I'll tell you," his voice was like silk, but there was a certain edge in his tone that made Yui uncomfortable.

He still had on that same smile, as though he was watching a performance.

His eyes were burning into her so she kept her focus on the ground. "It's a wonder you're still alive in this place. Have they treated you well?"

Surprised, she glanced up at him. "I'm fine."

"I see. Tell me, does this 'fine' nature of yours often have you running through the halls in the middle of the night?"

She was quiet.

"Then again, I suppose I can see why they're all in a frenzy. You do smell really good." His eyes grew darker as his gaze lowered to her neck. "Don't worry. I choose not to sample you until you make a full recovery. I'm sure your blood will taste like medicine right now and I might be inclined to kill you because of it."

"Ruki. What are you doing in here?"

The man turned around to face Ayato at the other end of the room.

"What? I only wanted to meet your… pet." He turned back to Yui. "I guess that ruins introductions. My name is Ruki. Ruki Mukami."

"Yui, come here," Ayato ordered.

Ruki was still holding her hand. When she went to move he squeezed it.

"Will you be so rude? I don't believe we've finished speaking."

She paused, confused. What should she do?

"Yui," Ayato said more firmly. "Come. Now."

She moved toward him and Ruki tightened his grip.

"Stay. Speak to me instead. I would like to get to know you better." His eyes scared her though. They said something entirely different.

Yui finally realized what was going on. Ayato was showing Ruki how well she was 'trained'. This was all a game to them. Vampires didn't live for much. Their lives were infinite and they had seen far more than she could imagine. Yui knew that she was their only source of true entertainment. It saddened her.

"Um- I. It was nice to meet you. T-thank you, Ruki."

He loosened his grip. "Very well. Until next time, Yui. I will have the pleasure of a proper introduction."

Yui met his gaze one last time. That strange smile was still there. She walked over to Ayato who seemed to beam with satisfaction.

"I smelled Laito in your room," he said as he led her out into the hall. "And here I find you promising yourself to another. How disgraceful. Were the rose petals for him too?"

Reviews would be nice. I decided to incorporate a character from the game. I'm still tweaking his personality though. Each of the Diabolik vampires will have their own chapter, unless you all strictly enjoy AyatoxYui development. Also, I can't describe how awkward it was for me to keep calling Yui a little bitch but you know how Laito is. He doesn't call her anything else. I don't know when I'll have the next chapter up. So follow and stayed tuned until next time...
