It was one of those bored nights.

The clouds were thick and obscured the moon and stars, but didn't even give the city the pleasure of being rainy and thundry and lightningous (when you are bored enough, "lightningous" can be a word!) and in fact, it wasn't even nice and cool but instead was an agonizingly mellow sort of warm. Yes, it was dark, it was humid, the weather sucked, and Yugi Mutou was bored.

"Lightningous," he muttered to himself, digging through the various exotic games in the back room of his grandfather's shop. The back room was where all of the neat games were kept, as well as a decent supply of opium, but that is not the point.

The point is, Yugi wanted to find a new game to play, and a new game was found.

It was a puzzle, made out of wood and some form of black leathery material. It was covered in some wicked cool symbols.
It was clearly evil. Yugi was thrilled.

"I found a puzzle to solve!" The boy squealed in near-orgasmic bliss. "It probably has nifty powers! As if I don't already have enough, but as I don't know what the hell they are -" he eyed the Sennen Puzzle. " - solving another one should be fun!"

"I have a bad feeling about this particular puzzle, Aibou," his Yami informed him.

"Mou hitori no boku," Yugi said flatly. "Gaaaaaaaaaaaame."

He blinked in an innocently impossible to refuse way. Yami was convinced. Thus it came to be that a cute little spiky-haired fetish boy and the voice in his head scampered off to solve a clearly evil puzzle on their dining-room table.

-YUUGIOH'S SUPER-COOL DESCENT INTO HELL!-

"Oho!" came the voice of Sugoroku Mutou from behind his grandson. Grandpa had a habit of popping up randomly. When he wasn't in a coma, that is.

"Grandpa!" Yugi blinked, looking over his shoulder. Sugoroku ignored the other Yugi hovering over his shoulder.

"You've found a heathen puzzle made by bloody Satanists," Grandpa beamed. "Solving it opens a portal to Hell. Now give it back so I can sell it to some witchy goth kid."

"Nevar!" Yugi stood, clutching the puzzle to his chest. "A good dose of evil is just what I need to kill the boredom!"

He fled. His grandpa tried to pursue, but fell over with a cry of, "My hip!"

Yugi decided that in order to complete the spiffy evil puzzle without his grandfather leering over his shoulder, he would toss it in his backpack and smuggle it into school. Where better to practise the occult?

So!

The next day, after school, Jounouchi, Honda, Anzu and Bakura found themselves crowding around Yugi's desk as he assembled the pieces of his new game.

"You know, it seems as though whenever Yugi plays any kind of game, the world goes straight down the toilet," Honda remarked.

"Yes," Yugi admitted. "But it's fun anyway."

"It doesn't look like a hard puzzle," Anzu commented.

"Does anyone care to make a bet on who loses their soul first?" Honda grinned, waving a hand.

"Shut up, Honda!" yelled Jounouchi.

"Try and make me!" He yelled back.

Yugi placidly pieced together the doom-board, which Bakura seemed interested in and offered to help.

"Nobody is going to lose their soul," Anzu growled.

"What about bodies?" Honda suggested.

"Guys, this puzzle is not going to steal your soul or your body," Yugi said calmly as he and Bakura worked on it.

"There, see, Honda?!" Jounouchi argued.

"It'll open a portal to Hell!" Yugi continued.

"WHAT?!"

And at that point, the final piece was set.

"BOOSH" is the only word I can think of to describe what happened next.
