Chapter 1: What Happened!

A lone figure was running fast. She had golden blonde hair, luscious lavender eyes, and a figure that made teenage boys drool at the sight. However, she was not running from admirers or even other jealous women but instead was running from something that civilization forgot almost 5000 years, and at the moment he was really ticked off.

"Why, Mai, I didn't even know that you hated my guts. If I did, I would have killed you days ago." a British accented boy called from the shadows.

"Just stay away from me you…you monster!" Mai shouted.

Now all this didn't go unnoticed, because just as the British accented boy was about to kill Mai, a man in a US Navy uniform came out from the guardhouse and shouted, "Stop where you are, BOTH of you."

When spotlights shown on the pair, they showed Mai with her clothing torn (For this, think Mai's clothes from the Duelist Kingdom Arc) and a teenage boy that literally was covered in shadows. The guards were shocked. I mean no one has ever saw someone covered in the inky blackness of shadows. The only thing visible on the boy was his eyes, and those shown with the light of many suns exploding.

The boy turned to Mai and said, "You may have escaped me for now, but don't think that I can't find you."

Then, he turned to face the approaching officer and said, "You would be wise to run."

When the officer didn't, the shadowed figure drew a knife and threw it straight into the officer's chest. He was dead before he hit the ground. The other guards had drawn their sidearms and opened fire on the teen, but the only thing they got was air as the kid had escaped by simply making the shadows grow around him.

One of the guards was about to place Mai in their custody when he saw that she had feinted. He turned to another guard and said, "Go get a litter, tell them we have an injured woman and a dead officer. I'll tell the commander to call NCIS. We have a big problem."

Ducky was going over his old case files with a look of minor annoyance. He would have asked his assistant to help him but the guy wasn't there at the moment.

'Of all the days to be alone why does it have to be on inspection day.' Ducky thought.

"Good morning, Dr. Mallard." the mailman said.

Ducky turned around and said, "Good morning, Harold, how are things at home?"

Harold the mailman barely acknowledged Ducky's comment and left him and the mail he delivered alone.

Ducky stopped for a minute to look at what to throw away when he noticed that a) he only received a trio of letters and b) one was the only official one while the other two were from friends. He turned to open the first letter and noticed that it was from his protégé who was at a naval base in Japan. It had only a simple greeting before it got odd for Ducky. He re-read it twice to make sure of what he was reading.

"Dear Dr. Mallard,

Before you open the official file, please read what I have to tell you. I know that you've been a fan of the Duel Monsters card game and have been keeping tabs on events but here me out. One of the Duelists, a girl named Mai Valentine, was found with a dead Lieutenant who had guard duty. I need your help. If it is ok, I need you to come to the new naval port here in Domino City.

Thanks,

Dr. Julius Cassidy

Ducky looked mystified and stymied at the same time.

'Why would Julius want me to go to Japan to see about a young woman. Even though she is supposed to be one of the best in Duel Monsters…' Ducky thought.

Ducky looked at his watch for a second and decided to go to Abby's lab to see if she could help him.

Gibbs was having a semi bad day, and it didn't look like it was going to get any better.

'First the alarm on my nightstand doesn't go off, then my favorite coffee shop closes due to a coffeemaker explosion (though how and why a coffeemaker would explode was beyond him), now I have a dead Navy lieutenant and a woman who wouldn't answer the local authorities' questions. Yep, this is going to be a GOOD day.' Gibbs thought.

"Boss?" McGee asked.

"What McGee?" Gibbs asked.

McGee turned from his computer and said, "I've been looking up 'Miss Valentine's' record. According to something called the 'Duelist Database' I need some kind of clearance or password from the game manufacturer to access her file."

Tony looked up from his latest attempt to ruffle Kate's feathers and asked, "So, it looks like the proby needs a little help from the master?"

McGee looked up and said, "It's not that, its just that there are firewalls that are so advanced that they really have me stumped. I doubt that even Abby would know what to do."

Just as Gibbs was about to smack Tony across the back of the head again, his phone rang.

Phone Log

Gibbs: Gibbs.

Abby: Gibbs, Ducky's down here asking for me to access something called 'The Duelist Database" and I was wondering if you had sent him down here to do something case related.

Gibbs: I didn't send Ducky down but keep him there. I'll meet you with Kate, DiNozzo and McGee shortly.

End Phone Log

"Kate, DiNozzo, McGee, we're going to Abby's lab." Gibbs said.

"Any explanation as to why, boss?" Kate asked.

Gibbs turned to her and said, "Nope, but Ducky's down there AND he's looking for the same thing that we are. Oh, DiNozzo?"

Tony turned and asked, "Yeah, boss?"

Gibbs smacked him across the back of his head again and said, "Don't think you get off just because I'm on the phone."

1111111111111111111111111111111111111111111111111111111111111111111111111111

All four met shortly and saw Ducky looking at a case file that should rightfully belong in the chief's desk. Abby was looking at her computer and was working hard to break through the firewalls in the database.

"Things a little tough Abby?" Gibbs asked.

Abby didn't even look up but said, "No, Gibbs, just a little difficult to hack into. You wouldn't believe the protection in this database. I mean there are redundancies on top of other redundancies and all those lead to no where. Almost like this thing has an AI protecting it. Or the programmer is really, really good at making sure to leave traps in a computer."

McGee looked at what Abby was doing and said, "Try having it backtrack itself and make it go crazy from chasing itself."

Abby looked at him for a moment and said, "Ok, this should work, if it is an AI system it'll go nuts. If it isn't the computers on both ends will crash."

Abby really put on her concentration and speed. Meanwhile, Gibbs, Kate and DiNozzo looked at Ducky and realized that he wasn't paying attention to what McGee and Abby were doing. Kate looked at Ducky and asked, "What are you looking at Ducky?"

Ducky finally looked up and said, "Just the file a friend of mine sent from Domino City, Japan"

Tony looked at Ducky with a weird face and asked, "Dominos owns a city in Japan?"

Right then and their Gibbs smacked DiNozzo upside the head and said, "No DiNozzo, Domino City is where the US Navy is putting one of new repair stations at. They think that the new facility would make it easier to repair a ship that's coming up the coast by setting there than having the ship go to Tokyo or Okinawa."

"Correct, Jethro, but they still need somewhat adequate medical facilities to have the base ready for ships. My friend is, at the moment, both doctor and chief medical examiner at the base. He has only one or two nurses to help with both medicinal and autopsy procedures." Ducky said.

"YEAH, I'm in at last." Abby shouted.

Gibbs turned and asked, "Find anything?"

Abby turned to Gibbs and said, "Not only that but I faked us a password and login name so that we don't have to worry about hacking in anymore, incase we need to look into the Duelist Database again that is."

"So what are they?" Ducky asked.

"Login: Swordstalker and Password: Rosencruz" Abby said.

Gibbs turned to Abby and said, "Print off a copy of Miss Valentine's record. Print off any of her friends records as well. After that get the hell out of there."

Kate turned to Gibbs and asked, "So where to now, boss?"

Gibbs smiled and said, "Pack for a long trip, Kate. DiNozzo, McGee, Abbs, Ducky, I suggest you do the same. We're going to visit Ducky's friend in Japan.

I hope this is a different kind of crossover story for everyone. This is going to be seriously different.

Legal Stuff

(Annoying, aint it?) CBS Broadcasting owns NCIS and VIZ/CN/whoever the writer is for the story owns YGO.
