A/N: I decided to take a break from my current Yugioh story and write a festive one! Some notes before hand. This is an alternate universe, obliviously. Yami Yuugi will be known as Yami by Yugi. The Millennium Items have different uses in this story. Not all of the Yugioh characters are in it, just those that would remain most important. Humor, supernatural, scary looking Yami's, and Halloween candy…what more could you ask for?

THIS IS HALLOWEEN

A Yu-Gi-Oh! Halloween Story

There's a world that coexists with our own with demons and monsters. The doorway between then opens on All Hallows Eve; but on one Halloween, a boy named Yuugi causes the doorway to open permanently…can he make odds with the King of Games and the demon world and bring peace to the worlds?

"I'll see you later, Jii-chan!"

"Don't forget to come back after school to set up the shop for this evening, Yuugi!"

Motou Yuugi nodded to his grandfather and ran down the street to meet with his friends. It was October 31st, meaning that it was Halloween. Lately Domino had been adopting more of American traditions, including this holiday. Kids everywhere were getting ready to do 'trick or treating', and the shops were setting up as well. Sadly the schools wouldn't let you dress up still, but everyone was rather excited anyways. Yuugi ran to the cross walk, seeing his tall blond friend Jounouchi Katsuya at the other side. The walk signal changed and Yuugi dashed over.

"Jounouchi!" Yuugi shouted, running up to him. Jounouchi turned, causing the small boy to run straight into him. Jounouchi chuckled at his enthusiastic friend and helped him up. "Thanks Jounouchi, you don't have to walk so fast!"

"I walk just find, you're the one that goes to slow." Jounouchi waved his hand around, excusing the discussion. "So you going to be ready tonight, Yuugi? Goin' trick or treatin'?"

"I'm too old for that Jounouchi; I mean you only see little kids do that stuff." Yuugi answered. "I promised Jii-chan instead that I'd help him with the shop tonight. He wants to set up a place inside so kids can get candy and also some new Duel Monster cards that arrived this week." He looked up at the street signs as they walked, seeing the banners and pumpkins and hay. "You'd never guess that America's traditions would catch on."

"Yea, tell me about it." Jounouchi agreed. "I found this weird book in the library last night that was translated into Japanese from America. It was talking about some weird world or dimension that existed along side us…filled with monsters and demons. It said that every Halloween this weird doorway opened up and let out all the things from that world."

"Sounds like a conspiracy story to me, Jounouchi." Yuugi sighed. "I mean, that's like saying that the Duel Monsters are real and they also exist in a world linked to ours. You know some of those Americans…they are just really bizarre."

Jounouchi nodded and they turned into the school's courtyard. Festive decorations were everywhere, clashing with the student's school uniforms. "I tell you, I wish the school would let us wear our costumes. Mine is going to be so awesome!"

"As long as it doesn't make people hurl." Yuugi snickered and Jounouchi sighed. The two headed off for their home room.

Yuugi swept the floor that evening as his grandfather finished setting up the tables. His father was dressed up as a vampire, which Yuugi thought was hilarious. Yuugi didn't wear a costume, just his black tank top with this studded bracelet and marching belt, finished with his favorite commando-style boots and his jeans. He had on his trade mark buckle collar as well.

"Yuugi, go down into the basement and see if there is any artifacts we can use." Suguroku said, while standing up. "I'm sure with all my collection down there we can find something! Ho ho."

"Hai!" Yuugi dropped the broom and ran to the door that lead down into the basement. He opened the door, running down the stairs and hitting the light switch. The lights flickered for a moment before producing a steady stream of light. Yuugi rushed over to the old boxes and opened them, searching for something that would produce somewhat of an eerie feeling upstairs. His hand hit something hard and he winced, moving aside the blankets to find a small golden box. Yuugi carefully took the box out of the larger box, heaving the heavy object into his lap. He moved the dust aside, seeing the solid gold box with Egyptian writing on it. Yuugi placed it beside him before quickly looking around and finding a few other artifacts.

After balancing the items in his hands, he slowly went upstairs and gently placed them onto the table. He looked at the golden box again, tilting it to the side. His grandfather came over to him. "Ah, Jii-chan, what's this? I haven't seen it before."

"One of my first finds! It's a puzzle." Yuugi's eyes lit up. He loved puzzles. "I was going to give it to you for your birthday…but since you found it, you may have it now. Legend has it that no one has solved it…and that he who solves it inherits the powers of darkness!" Suguroku leapt up, his hands outstretched above his head and his face twisting into a scary one.

"Jii-chan…that may scare the kids, but it doesn't scare me!" Yuugi retorted. He grabbed the box and ran upstairs. "I'll be upstairs!"

"What about the children?" his grandfather asked, but the only reply he received was the slamming of Yuugi's door.

------------

Yuugi scratched his head, looking at all the puzzle pieces. He had been up in his room the last four hours. He could understand why no one had solved it, the pieces made no sense! Some were mangled into odd forms; others looked as if they weren't part of it at all. He sighed, reaching over and grabbing his soda and taking another large drink of it before returning to his puzzle. He had been so far successful; he'd say that little under half of it was done. It seemed rather simple to him, why was it so hard for others to solve it?

He looked up as the shop door opened. He took a peak outside, seeing the kids run from the Game store happily. A tall teenager was outside, his white hair skewed all over the place. He had on a torn robe, and what seemed like large scars under his eyes. The teen brought his near-crazed look up to Yuugi's, a smile curving on his cracked lips. Yuugi shuddered; some people's costumes were just too scary.

The teenager outside looked up at the sky and slowly turned. The sky seemed to darken with every piece that Yuugi fit together. The teenager stopped a moment as some kids ran right through his body, as if he was not there…or a phantom. The phantom slowly turned towards the children, anger flickering in his crazed look. He stopped as all sound seemed to disappear. He smiled once again.

Yuugi leaned back and stretched, standing up. He sighed, turning from the puzzle and going downstairs to check up on the shop. He looked around, not seeing anyone. He figured that his grandfather had just gone outside to wish the children off. He returned upstairs and searched in the golden box for anymore pieces. He pulled out the largest and final piece, looking at it the Egyptian eye in the center. He thought for a moment before turning back to the ten pieces, eleven counting the largest one, of the puzzle.

As he sat back down, Yuugi shivered, getting the feeling someone was watching him. A large shadow had appeared behind the boy, watching his every move with its red near-crazed eyes. Yuugi paused, staring at the slowly forming pyramid, confused. It seemed now suddenly as if one of the pieces changed. The shadow lifted its right hand, as did Yuugi's. Yuugi watched as his own hand against his will picked up a small piece and inserted it into a hole. Yuugi blinked, turning and looking behind him, but saw no one. He sighed, shivering.

"This holiday has me all worked up, thank god it only comes once a year."

Yes, once a year little Yuugi. Yuugi bolted up, searching around his room at the dark and strong voice he had heard. Surprised? I suppose you would be. Turn back to the puzzle Yuugi; I will help you finish it.

"How do you know my name?!" Yuugi shouted out into his room.

I know everything about you. You opened your mind to me as soon as you opened the box. But do not worry, I won't cause any harm to you as long as you cause none to me.

Yuugi nervously tried to completely the puzzle. He felt as if it was not his own will any longer that did so, but the voice's will. Finally he reached for the largest piece and fit it into its slot. Yuugi jumped back, knocking his chair over as the golden pyramid began to glow, sending rays of black light into the room and through the window into the sky. Yuugi tripped over the chair and hit the floor, covering his face with his arms.

He lay on the ground for a few moments before raising his head, seeing that the light was gone. He stood up shaking, and looked over at his mirror on the wall. It seemed fogged up. He came over to the mirror, placing his hand on it and moved it around, trying to get the fog to disappear. He sighed in frustration as it didn't work, keeping his hand on the mirror. His hand felt warm and as he pulled it back, a hand with its fingers curled around his own hand came out of the mirror as well. The nails were pointed, a black glove on it as well.

Yuugi let out a scream and jumped back, holding his hand. The figure pulled itself out of the mirror and brought its head up to see Yuugi. His skin was a dusty tan, and he was about a foot taller than Yuugi. He had a similar hair style, except his blond dusty bangs spread out in all directions and his black and blood red hair stuck up everywhere. Some of his blond dusty bangs fell in front of one of his eyes, causing only the right eye to be seen. Yuugi noted the cobwebs that were in the darker man's hair, and the shrouded outfit.

"Ha…ha, you must be a trick or treater…nice outfit, and nice scare…now you can be on your way." He gulped, going to the opposite side of his room rather quickly. "I mean if you are upset about the candy or something….."

The figure's crazed red eye scanned the room quickly. It then landed on Yuugi, a smile curving on his lips. "Hello, Yuugi." Yuugi's eyes widened at the voice, it was the one that had spoken to him.

"So…this is Halloween…All Hallows Eve now a days."
