A/N: This is a short three chapter one shot. It just came to me one night, and I wanted to try it out. This is a Halloween-esque fic, and a total AU. There are not many vampire!Vincent fics out there, and I thought it would be fitting since the holiday is coming up. And what more fun way for Yuffie to be the naive silly girl in the story? This will be rated M. You've been warned. :)

Anyway, I hope you enjoy the first of three!

Deal With The Devil

"You're crazy, Cloud."

Yuffie rolled her eyes at Cloud's serious expression. It was almost midnight and the town of Nibelheim seemed to fade into the distance as she looked out to the abandoned mansion before her. She had to admit that ever since she seen the place with her own eyes; tall, dark and broody looking, an uneasiness would settle in the pit of her stomach. With it's old gothic windows and the way the vines crawled and twisted up and around the building, it gave her the impression of a cage. The image of it seemed to draw the air from her lungs, leaving her dizzy and heavy on her feet.

Yuffie would never admit that the sight of the place made her nervous, not even to herself.

So for the past half hour, Yuffie waited for her friends, Cloud and Tifa, to show up at the front gates of the supposedly haunted mansion. It was two days before Halloween, and Cloud had conveniently came up with an elaborate ghost story about the abandon building, to which Yuffie passed off as completely false. Ghosts of lost souls? Supernatural beings of the night? How old did Cloud think she was, four?

It was so silly.

That was her notion until her eyes gazed over at Tifa's deep solemn expression.

Ghost stories didn't scare Yuffie in the least, but what did make her wary was the fact that Tifa seemed to be going along with Cloud's ridiculous plan. Tifa. The sensible and reliable one. Strong, calm and logical. So, was she also trying to trick her or did she actually believe in his fairytale?

"What do you think, Tifa?" Yuffie wanted to hear it from her own mouth that this whole thing was stupid.

Pretty features marred into a frown as Tifa pulled nervously at her long brown hair, her head twisting up to face the Shinra mansion.

It didn't take a psychic to know what she felt about it.

"I've heard a couple stories from my mother before she passed away," Tifa began, sadness flashed in her scarlet eyes for a brief second at the mention of her deceased parent. "She and her friends used to walk by this place each day before and after school. They got a little courageous one night, and went inside. I'm not really sure what happened; she wouldn't tell me. But after that, she avoided the place, they all did."

There was a moment of silence between the three of them.

"The Shinra Mansion is not haunted, okay?" Yuffie seemed to be adamant with the fact and the more she thought about it, the more she believed herself to be right. They just wanted to scare her. "And if you think I'm going to believe that ghosts and vampires exist, you both are crazier than I think you are."

"Oh?" Cloud raised a blond brow. There was an unspoken challenge in his voice.

"Yes." Yuffie had heard it and replied with one of her own. This was typical between the two.

The older man eyed her for a moment, a smile spreading across his face. "If so, I dare you to spend one night in the Shinra Mansion." If Cloud knew Yuffie, and he knew her well, she would take this challenge with both hands.

"Cloud," Tifa warned.

"Oh, one night, so scary!" Yuffie mocked him with a cocky smirk. "Why not make it two?"

Tifa was shocked. "Yuffie!"

Cloud made a noise in the back of his throat, pursing his lips. He had to admit that the legend of the mansion and the time of the year did go very well together, and he wasn't surprised to find out that Yuffie didn't believe him in the slightest. But it didn't make what he said any less true.

Nibleheim was notorious for haunted buildings, and they grew up with the biggest one of them all. Ghosts of bitter souls wandered it's long dark hallways, wailing and moaning about their life's regrets as they lose more and more of their humanity each night. Glimpses of dark scarlet eyes that appear in every room, seemingly glaring and definitely angry. But in the basement lies 'the evil one'; a vampire locked in a deep sleep for eternity.

Thrill seekers, like Yuffie, have always dared to stand up against the rumors of the mansion, to prove them false, and to show others that they were above in believing the impossible. And every time, they would run out, screaming and swearing to never enter again.

Cloud held back a chuckle at the image of Yuffie running out of the mansion, crying and blubbering about how much he was right.

"If you can make it past the first night," Cloud said. He can already hear Yuffie's refusal to go back in the mansion. No one entered a second time. This bet was a sure win.

"Two nights." The demand was back in Yuffie's voice. "What's the wager?"

Cloud thought for a moment. Yuffie and Tifa waited patiently for him to answer. Finally, "If I win, you have to take both mine and Tifa's working shifts at Seventh Heaven for a week."

Yuffie breathed in, already not liking the bet. Tifa's father owned the local bar; Seventh Heaven where she, Tifa and Cloud worked. Nine times out of ten, the place was busier than shopping malls on Christmas eve. She really had to win if she was even thinking about making this bet with him.

Come on, Yuffie. Ghosts aren't real, right?

Yuffie slid her tongue along the back of her teeth in thought. She was starting to feel angry at her own need to mentally assure herself that she had nothing to worry about. "And if I win, you will give me your tips for two weeks."

Cloud gaped at her, finding her part in the bet really unfair. "Why two weeks?"

"Because I don't think it would be fair to take Tifa's as well. You're the butt-face in all of this."

He thought for a moment, his lips set in a straight line. "Fine."

"Fine."

"Two nights, Yuffie," Cloud reminded her.

Yuffie smirked, feeling like she already won. "Two nights, Cloud."
