Kaiba's first name is a secret until it gets mentioned. I haven't figured out which one to use yet but I will decide for the last chapter.

I stopped by a small game store on my way home from school. It hadn't been a very eventful day and I spent most of it wondering how everyone else got on without being bored to death.
There were the puppy and the girl and their pointy haired friend Yugi buying game cards from what, by family resemblance, was Yugi's grandfather.
"Come on in!" He said as the bell above my head rang.
"What's this? Yugi, this is your family's game shop?" No wonder they were inside playing games while everyone else was out on the basketball court.
"Oh! You're Kaiba from our class aren't you?" Yugi smiled brightly as the mutt's mouth fell open.
"Hello." I paused and noticed the cards in Yugi's hand. "You play Magic and Wizards"
"You play too Kaiba?" The mutt looked at me hopefully. "That's great! We're going to play at school tomorrow. You can play with us"
"Huh... Gimme a break. You actually think you're in my league?" I paused. "Let me see your cards"
The mutt handed them over easily. I looked them over critically before bursting out laughing and throwing them in his face.
"What a beginner. You could never match me." Joey flipped out and scrambled to pick up all his cards. "I'm good enough to compete in the national competition. You could never win against my deck so it'd be pointless to play against you"
"Come back once you've got 10000 cards at least, and then we'll talk. If you get 50000, I might consider playing you." I chuckled, smirking, then turned to the shopkeeper.
"Do you have any good cards here? I might be persuaded to buy." He turned enthusiastically to the shelves behind the counter.
"Hn...?" A card lay out of any sort of case. "Wha? It can't be!" I picked it up to make sure it was real.
"The legendary Blue Eyes White Dragon..." I barely breathed just as it was snatched from my hand.
"Old Man! Where did you get that card! What's it doing here!" He held it back. "Let me have a look at it"
"Well... just a look." He handed it to me. I couldn't believe it. The card radiated power. And with an attack of 3000 why shouldn't it? If I could only put that into my deck... I'd be invincible!
The old man snatched it back again. "Alright, that's enough"
"Old Man! Give me that Blue-Eyes White Dragon!" I opened my suitcase and slammed in onto the counter in one fluid movement. "I'll trade you all these cards"
"Wowza! A briefcase full of cards!" Yugi and co. chorused.
"I'm sorry, but no." The old man didn't even think it over, a fatal mistake in my presence.
"No matter what?" I wouldn't trade that card for the world and he obviously knew how much it was worth. It didn't matter though. Most people lost their senses around me. I leaned on the counter making full use of my feminine attributes.
"Kaiba isn't it? I know you want this card so much... however I have good reason to hold onto it." Either his resolve was weakening or he believed I wasn't going to get that card today.
"An important gamer friend of mine in America gave this card to me. This card is as important to me as my friend!" He motioned to the picture on the shelf. "I could never give it up"
"And it's the same with common cards... If you really treasure something, it grows a heart of it's own, just like this card. You would never trade anything for that heart." He continued. I felt the sneer make it's way onto my face.
"So take good care of each and every card in this trunk Kaiba, then you'll find the true strength of the game." I closed my case with a bang.
"Fine... I get it. Later then..." I turned and left, unsure of why there was a pang in my chest and a tear in my eye.
