A/N – Hey people! I had a sudden idea for a Yu-Gi-Oh fanfic and I decided to try it out. If you all like it, then I'll write more. This is my first ever shonen-ai fanfic and I hope I don't screw it up too badly. Please excuse me if I do.

Summary: Seto Kaiba, one of the top PI's in Japan. Katsuya Jounouchi, rookie extraordinaire. Will they be able to work together to solve a bloody case, or will they end up killing each other first? Eventual S/J.

Disclaimer: I do not own Yu-Gi-Oh. If I did, Kaiba and Jou would be together by now.

Murdering Passion

Seto Kaiba sat as his office desk, angrily shuffling through a mountain of papers and folders. Sheets littered the floor in a messy display of anger, ripped papers were crushed up into little balls that were unable to make it through the journey to the garbage can. The rich mahogany of the desk was unseen under the unorganized mess that was Seto Kaiba's office. The brunette sighed and crushed up yet another paper, throwing it at the basket without even looking at it.

There was a light knock at the door, signifying yet another of his annoying co-workers. With a growl, he asked the person to enter.

"Uh, the boss would like to speak with you Kaiba." Came the infuriatingly high-pitched and sickeningly sweet voice of the secretary, Kotomi.

"Fine. Get out." He snarled, getting up from his leather chair and stalking towards the door. Kotomi flashed him a sugary-sweet smile, causing the brunette to scowl. "Do I need to define what the words 'get out' mean?"

"Of course not." the girl smiled before twirling around in her short skirt and heading back to the front desk.

Kaiba sighed again and made his way to the chief's office. Seto had been a PI for a few years now, and at only 22 he still had plenty of time left to make it to the top. Already he was one of the top agents in Tokyo, and he planned to keep it that way. Except…

'This stupid case just makes no sense.' He thought irritably as he entered the elevator, punching in the number for the top floor. He had been working on it for three weeks now, and ever since the first one there had been two other murders, one for each week. The entire office knew these crimes were connected, as the murder victims were either police officers or private investigators like him. Someone was after the justice system, and they were doing a very good job of hiding themselves.

Blood dripped from the tip of the pliers, leaving no doubt in anyone's mind as to what they might have been used for. A dirty deed had been done this night, and the pathetic PI's wouldn't even find the body until the next day, if they were lucky. A sadistic laugh grew in intensity until it was echoing off the crimson walls until it finally subsided, leaving an eerie quiet in its wake.

"Come and get me if you can, Seto-kun."

Kaiba stopped as he reached the office door of the boss and he knocked on it sternly.

"Come in." came a muffled voice from inside, and Kaiba grabbed the brass doorknob, opening the door and closing it swiftly.

"You called for me, Yamato-san?" Kaiba said coldly, sitting down in the chair opposite of the chief.

"That's right, Kaiba. As you know, this case is getting way out of hand, we need to find out what's going on as soon as possible." Yamato began, leaning forward on his leather chair and looking at the brunette.

"There's been another murder?" Kaiba guessed, calmly resting his head on his hand.

"Hai. Down on Shijuko street. Did you know Tomoko-san?" the chief asked, pulling out a notepad and scribbling an address on it before handing it to Kaiba.

Kaiba took the paper. "Hai, I met her. She's the red head, correct?" he answered, placing the paper in his trench coat pocket.

"That's right. Now, Kaiba, I know you're not going to like this, but I think you need a partner." Yamato said suddenly, leaning away from Kaiba as he waited for the brunette's undoubtedly angry response.

Kaiba scowled. "I don't need a partner. You know that full well, Yamato-san."

"I understand how you are feeling Kaiba, but what happened, happened and there's no turning back. I am ordering you to accept your partner and work with him. You take on too much work and I'm worried for your safety as well as that of the other workers here. I need this case solved, and solved quickly."

Kaiba glared at the chief, knowing he could not disobey a direct order. Yamato could easily find another PI to solve the case. He sighed, defeated. "Fine. Where is he?"

"He should be here any mom-"

"Konnichiwa (1)!" came a cheerful voice as the door banged open and a grinning blonde stood framed in the doorway.

'God save us all.' Kaiba thought, glaring at the blonde.

A/N: Yay, I've finished the first chapter. I know it's a bit short, but please bear with me. The next few chapters will be a lot longer. I just wanted to see if this story will catch on so please review! Thanks!
