"Wait, did you say Domino City?" Kaiba asked.

"Yes, Yumi Ishiyama requested that she and her friends be allowed to go to Japan for a cultural lesson." principal Delmas said.

"Well I should tell you, I'm about to hold a tournament there, the Battle City tournament, so I suggest your students reschedule their trip." Kaiba said.

"Wait, what's Battle City?" Jeremy asked. "What kind of tournament is it?"

"The Battle City tournament is the largest Duel Monsters tournament to ever take place, and the winner will be declared the King of Games." Kaiba said, "To add life to the tournament all duels will use this, the new and improved duel disc."

That must be X.A.N.A.'s weapon, but what can it do, Jeremy thought. "Mr. Kaiba, would it be feasible for me and my friends to watch the tournament, it might inspire us to bring it here to Kadic Academy." he said.

"You don't know what Duel Monsters is? Well, that's disappointing, fine just don't get in the way of the tournament." Kaiba said before Yumi ran in.

"You're Seto Kaiba, the president of Kaibacorp, I'm honored to meet you, my name is Yumi, I actually duel a little." Yumi said. "Would you mind playing me and giving me some advice?"

"Why not, but first I have something to attend, I'll be back tonight." Kaiba said.

"Hey Yugi what do you think that big announcement will be?" Joey asked.

"Not sure Joey, but it should be on soon." Yugi said when Kaiba appeared on the television.

"Ladies and Gentlemen, I am Seto Kaiba, and I'm here to issue a challenge to any duelists who think they can hold their own in the game. This tournament will have some new rules, but those will be explained over the next few days, now then if you want to enter you sign up at this location." Kaiba said while an address appeared on the screen. "Now I wish you all good luck, you'll need it."

"Man a new tournament, as much as I hate Kaiba the guy knows how to get people psyched, I plan on winning the whole thing." Joey said.

"Joey don't get ahead of yourself, after all I'm planning on entering and you can bet Kaiba is too."Yugi said.

"Well, in that case I should work just that much harder to beat you guys, don't forget I was the runner-up at Duelist Kingdom." Joey said while grabbing his deck.

"Yumi, why are you so excited about this Kaiba person?" Aelita asked.

"Well, before I left Japan I got to see the championship match of a duel monsters tournament, Kaiba won and the strategy was incredible, I decided to learn how the game worked and well, I'll show you guys how to play." Yumi said when a jet flew in resembling a white dragon."

"You said your name was Yumi, are you ready for our duel?" Kaiba asked.

"Yes, thank you very much." Yumi said as she picked up her cards.

"Duel." said Yumi and Kaiba simultaneously.

Yumi 2000 Kaiba 2000: "You can take the first turn."Kaiba said calmly.

"Thanks, I draw, now I set two cards facedown and summon my Dark Elf in attack mode. That ends my turn." Yumi said.

"Alright, in that case it's my move, and I summon my X-Head Cannon, next I set two cards facedown and end my turn." Kaiba said, when Jeremy's laptop flashed and Yumi's cards got blown off the field.

"I'm sorry, it must have been the wind, Odd shut the window." Yumi said.

"It's fine I'll just have my turn be the first, but try to keep your cards on the table this time." Kaiba said.

"Right, my move." Yumi said drawing a new hand. "No way, this is incredible, somehow my deck got changed."

"Well, let's see how effective these cards are." Kaiba said, slightly curious about a new deck that a computer somehow created.

"Ok, I play the field spell Lyoko," Yumi said before placing four coins on the card, "This card has five effects, and the first is chosen by you, Desert, Ice, Mountain, or Forest."

"Interesting, I chose Mountain." Kaiba said.

"Ok, in that case the effects have all been decided, and Mountain allows me to summon one monster during your turn if I have none on the field." Yumi said. "Now I summon Tarantula, now I attack your X-Head Cannon." Yumi said. "One facedown and I end my turn,

Yumi 2000 Kaiba 1600: "My move, I activate my White Dragon Ritual card, next I send Hitotsu-Me Giant to the graveyard in order to summon Paladin of White Dragon." Kaiba said with a smirk, now I summon Blue eyes White Dragon by tributing my Paladin, now I attack with Blue Eyes. That ends my turn."

Yumi 1200 Kaiba 1600: "ok, I summon Krab, and when I summon him I can destroy one card on the field, so I destroy your Blue eyes White Dragon."Yumi said.

"I activate my facedown card, Ring of Destruction and Ring of Defense, now your Blok is destroyed, and we would both normally take 1400 points of damage, but my Ring of Defense protects my points." Kaiba said as Yumi lost the last of her points."

"Excuse me would it be alright if I gave the game a try?" Aelita asked.

"Fine, I'm always up for a challenge." Kaiba said.

"Yumi, could I borrow those cards?" Aelita asked.

"Sure, here you go Aelita." Yumi said.

"Duel." said Kaiba and Aelita simultaneously.

Aelita 2000 Kaiba 2000: "My move, and I activate the Lyoko field spell." Aelita said.

"In that case I choose Ice." Kaiba said.

"Ok, in that case I can activate trap cards on the turn I set them by discarding one card." Aelita said. "Next I set one card and discard my Tarantula to play Lyoko Warriors Arrive, now I summon Ulrich, Yumi, Odd, Aelita, and Jeremy. That ends my turn."

"Well, that's quite a powerful card, but I summon my Vorse Raider and attack Jeremy." Kaiba said.

"I use the effect of Yumi, now I can negate one attack per round, but in exchange Yumi can't attack next round." Aelita said.

"In that case I end my move with this facedown."

"My turn, I draw and I activate Odd's special ability, now I can see one facedown card on the field and flip a coin, if I get a tails I destroy the card." Aelita said as Kaiba revealed his Ring of Destruction.

"I'll flip." Yumi said before flipping a coin. "Tails, the card is destroyed."

"Alright, next I attack Vorse Raider with Ulrich, both monsters are destroyed. Now I attack with my other monsters." Aelita said. "So I win?"

"Not bad, you have skill, I think you might be good enough for my tournament I'm looking forward to seeing how you do." Kaiba said pulling out a small book, "The rules are slightly different than how we just played, I'm looking forward to seeing you there." With those words Kaiba got in his jet and flew off.

(X.A.N.A. interfered with the Kaibacorp mainframe and as a result a Lyoko deck appeared in Yumi's possession, now Kaiba has invited Aelita to compete in Battle City. Next chapter will begin the tournament, and the Lyoko Warriors will meet Yugi and Joey. As always any reviews or critique is appreciated.)
