6/07/2011-I'm back, people! For how long it's hard to say. I've been having writer's block for my novel for over a year now and suddenly this idea hit me while I was bored at work. During my obsession with the Sly Cooper games I kept seeing Yami and Yuugi doing the roles of Sly and Carmelita but I couldn't formulate how to put it together. Now I have. Bear with me, people.

As the summary says, this is the Sly Cooper and Thievius Raccoonus game world and plot with the YGO characters. Chosen references from the game are present along with whatever I throw in there.

I've seen the Shipper's List so I hope I get this right. This story is mainly Puzzleshipping. There's some Trustshipping, and hinted/mentioned Tendershipping and Bronzeshipping. Results may vary. Don't like, don't read!

Dark Game: The Sennen Puzzle

Chapter 1: Phantom Thief

Domino - Japan

4:20 AM

Everyone should still be asleep by this hour, right? True, most people were too busy snoring to notice a shadow prowling over their heads. A black silhouette leaped from roof to roof, stepping over neon signs and poles with the grace and elegance of a feline. In just a few minutes it stopped on top of a two story building. The sign on the second floor read Interpol in katakana.

Once it reached its destination, the black covering its face peeled back on its own revealing a light face with narrow crimson eyes. His entire body remained covered in shadow. Looking around in case of any witnesses, he felt something vibrate against his back. His hand reached back and went into his back, and pulled out a small pair of binoculars. They vibrated faintly against his palm. Placing them over his eyes, he saw an image appearing on a corner of the front lens. It was a young man with spiky white hair and narrow green eyes.

"Yami, helloooo!" he said in a sing-song tone. "Testing, 1, 2, 3. Do you read me?"

"Bakura, what the hell are you doing?" Yami almost yelled into his binoculars. "Get off this frequency."

"I just wanted to how you're doing. I mean, you're breaking into your girlfriend's office. Don't forget to bring her underwear."

Yami really wanted to wipe the smirk off his face. But before he could retort, he saw the image distorting, heard someone yell and protest, and a loud thud, before the image returned. This time it was blue-eyed brunette with a scowl.

"No wonder you wanted to handle this alone," he said. "Now that the idiot proved the new binoculars is not affected by our distance, count on me to be your eyes and ears. I got the Interpol security system scoped. To get inside you have to go through the air vent on the roof. It should be a few feet from you."

"Alright, Seto. I'm going in."

The image changed again to reveal a sandy blonde with very wild spikes and purple eyes.

"And don't forget, you got me at the wheel, Yami," he said. "All you have to do is grab the file and get back to the van, we'll do the rest!"

"Fine, Marik," Yami replied. "But if you try to run over hobos again, I'm going to kill you."

"But it's fun!"

Yami chose to ignore him and put the binoculars into his back again, where they disappeared. The shadows covered his face, leaving holes for his eyes. He looked around and spotted the air vent but it was out of reach. There were a few antennas and a water tower next to it. So he made his way to the water tower, leaped from there, and using the antennas as stepping stones he reached a wooden platform with the air vent on the other side. The shadows covering his arm separated from his skin, revealing his hand and then shape shifting into a large solid black cane. All he did was smash the thing into the vent and it broke into pieces easily.

Yami didn't get too far through the tunnel before he reached the small railing on the other end. Peering over it, the thief discovered about fifty yellow lasers shooting out of the walls, pointing in different directions like a twisted web. The binoculars on his back vibrated again but he didn't need to pick it up before Seto's voice came out of it.

"Be extra careful in there, Yami," he said. "Break one those laser beams and you'll set off the alarm. Not to mention you'll be fried to a crisp."

With that the binoculars went silent again. Yami smirked at that last remark. There were other railings on the way down. It would be like going down a set of stairs with extra high steps. No problem.

The cane melted back into his skin, turning his hand black once more. Then Yami jumped off the railing calculating his distance so he landed on the railing down on the right side. From there he went to the next one right in front of him, passing the gaps between the laser beams without touching them. After the fourth platform he landed on the floor right next to an orange device tall enough to reach his knee. The phantom thief calmly reformed the cane and broke the device. All the laser beams over his head flickered and disappeared.

Outside the laser room, the halls were quiet and dark. There were no cameras nor a officer to notice the intruder. Yami easily sneaked through the second hall until he reached the red door on the end with a large gold star on it. It was Inspector Mouto's office. Before he could use the cane, though, Seto voice came from his back again.

"Wait, Yami," he said. "That door is ridged with a silent alarm. Look for a way around it."

Doors were never his preferred entry method. Yami made his way out the window to his right. The balcony to the office was a short distance away; he creped along the ledge to it and went in through the window. The thief went straight for the vault next to the desk, and he heard Seto calling him.

"That's it," he said. "This is where Inspector Yugi Mouto stashes all his important files. I hacked into the police security mainframe and discovered this vault's combo. Dial 9-3-7."

Yami did just as he was told and the vault opened almost instantly. Inside he found a file folder with his picture and the name Yami Sennen on it, and he took it.

"Nice job, you did it," said Marik's voice. "If you come down the fire escape and head through the parking lot, we'll be waiting in the getaway van.

As the binoculars went silent again, Yami took something out from his back and placed it inside the vault where the files were. It was a small jigsaw puzzle piece. The cane melted into him again; he stepped back out the window and onto the fire escape.

"Criminal!"

The phantom thief turned his attention to the building next to Interpol to see someone landing on its roof. From there, the person made another flip, gracefully landing on a neon sign, keeping perfect balance. Bathed in moonlight was a short young man dressed in dark blue jeans and boots, with a plain purple shirt and a black cotton jacket. His star-shaped tri-colored hair would've looked funny if it wasn't for the focus he held in those huge amethyst eyes. That and the big-ass pistol he held.

"Shadow," he said. "I've caught you red-handed."

Yami allowed the shadows to peel back from his head, revealed his star-shaped tricolored hair. He gave out a pleasant smile. "Ah, Yugi," he said. "I haven't seen you since I gave you the slip in Bombay."

"Which reminds me," Yugi replied. "You need to return the Fire Stone of India to its rightful owners."

"And I was thinking about giving it to you and a token of my…" He noticed the gun. "Hey, the bazooka is new. It really brings out the color of your eyes; very fetching."

"You think? This pistol packs a paralyzing punch. You ought to try it; might snap you out of you crime spree."

"And give up our little rendezvous?" He smirked at that.

Yugi's eyes merely narrowed. "Plenty of time for that once you're safely behind bars."

"I'd love to stay and chat, but I just dropped by to pick up this case file. I think you've had it long enough."

Yugi responded with the first shot. A huge yellow bullet sparkling electricity blew up the railing where Yami stood a few seconds before it hit. Yami jumped down one platform at a time without bothering with the stairs. The shots came so fast he barely dodged the last one before landing on the parking lot.

"Yami," Bakura called over the binoculars. "Lesbo coming your way."

"What?"

A split second after that, Yami dodged a roundhouse kick to his head from the side. A blonde blue-eyed girl wearing short pants just above her knees, a jean buttoned up jacket, and high-heeled boots had appeared out of nowhere. A solid metal badge was pinned to her left breast pocket.

"I've been waiting for this," she said, smirking at him. "You won't get away from me!"

Rebecca, he remembered. Barely eighteen years old and almost a pro. Yugi's shots seem to pause after she began attacking him. She launched punches and kicks after him. She was a karate student; to the thief it was obvious who taught her and she was taught well. The girl was fast and, for someone fighting in heels, pretty well balanced. Still, not fast enough as Yami easily ducked and rolled under another kick, running past her.

The lot was blocked with police cars and turned over garbage cans. The thief just kept jumping over everything, sometimes using car hoods as stepping stones. Yugi changed his position to get a better target, shooting again once Yami had a certain distance from Rebecca, either landing on a lower roof or another sign. But every shot just barely missed as Yami disappeared into the black van waiting just outside the parking lot. It sped away just seconds before Yugi landed on the ground where it was. His partner arrived beside him.

"You can't escape me, shadow," he yelled after the van. He wouldn't be able to catch them now, he realized.

"Oh, I almost had him," Rebecca said, crossing her arms, glaring after the van.

Yugi holstered his shock pistol. "It's alright, Rebecca," he said. "After tonight, we'll be one step ahead of them." The inspector felt something vibrate against his thigh, and he pulled out his cell phone. "Hello, Ryou. Yes, they're gone. You got any idea where's they're going first?"

After a pause, he had an ear to ear grin as if the last few minutes never happened. Rebecca mirrored his good mood, knowing Ryou was on to something. "We're there!" Yugi turned back to the direction the van went off to. "You just wait, Shadow. I'll get you yet."

Meanwhile, inside the getaway van, Yami slid down against the wall and nearly fell on his ass, letting out a loud exhausted sigh as the shadows completely peeled off him. His star-shaped hair didn't look like it was pressed at all from staying hidden; he was left in grey pants and tank top, and black boots.

"Ugh…" he groaned, rubbing his eyes. "I stayed in that form for too long."

Seto was riding shotgun with his laptop wide open and wearing an ear piece, completely ignoring the others for the time being. Marik was driving, and Bakura sat next to Yami eating from a bag of potato chips. Bakura was actually the first one who spoke.

"So, is Yugi still mad about the bar incident?"

After a short pause and a bump, that Marik swore was not driving over a hobo, Yami replied, "Say that again and I'm throwing you out the window."

"You got the case file, Yami," Seto asked without looking back, just typing away.

The phantom thief smirked as he pulled the folder from his now visible backpack. "Right here. You better call Isis. We'll need the whole team for this."

There you have it. Did you know the Japanese version of Sly Cooper is called "Kaitou Sly Cooper"? It means Phantom Thief Sly Cooper. That's where I got the title for this first chapter. If you saw all the thief abilities he learns by from first game all the way to Sly 3, you would probably agree with it.

I wanted to introduce both teams here completely but I didn't want the first chapter to be too long. This was supposed to be the prologue but I changed my mind at the last minute. You'll get to see all the members in the next chapter. I'll be revising this chapter just in case cause I was so excited to put it in I rushed to do so. Let me know what you think as long as responses are as constructive as possible, even if you don't like it. Flames will be used to make smores. Thank you!
