(A/n: I have reviewers saying that some of the segments in this fic are too short. Well,the reason is because it's a diary form fiction. In a normal diary, you write as little or as much as you want. The Kaiba brothers are no exception. Thanks for the reviews, and I hope you will keep reading!)

Day 13: Seto Kaiba (My home office)

Well, it's 7:30am on Mokuba's birthday. He is still sleeping. The Robas and Yugi are going to be here at noon. We are all going to KaibaLand for a special day of dueling. No competitions, no league, just clean fun.

I know what you're thinking, diary,and you're right. I'm crazy for caving and hanging out with Yugi Motou. I hope he remembers this doesn't mean we're going to suddenly become best friends or anything. I'm doing it for Mokuba. And only for Mokuba. There are a few other surprises in store for my little brother too. chuckles He's got no idea that I have sent your product information to my distributors already, and you're going to be out on the market as of 12pm today. Well, I better get ready for breakfast. I hear the cook in the kitchen, loud as hell as usual. I'm sure Mo will write in here later on.

Seto Kaiba Out!

Day 13:Mokuba Kaiba (Portable Diary from the limo!)

Oh man! I can't believe Seto did all this for me today! We've had the best day ever today, but I'm getting ahead of myself. Let me start from this afternoon.

Seto said he had some tests to run at Kaibaland, so we headed over there. I thought to myself, okay, so we're going to spend the day in his lab? Nice birthday, Big Brother. Well, what actually happened was so amazing, I'm still in a daze. When we got there, instead of running the test, Seto put the closed sign on the gates, and we headed to the dueling rink. (a/n: Think like a skating rink.) When he flipped on the light, a shout of "Happy Birthday!" came from the field. There stood Yugi, and the Roba brothers. I couldn't believe it. Well, yeah, I figured that the Robas would be involved, but Yugi? I looked up at Seto, who had this smile on his face. Then, it was time to duel.

First, it was me, versus Seto. That match was so close, but his Blue Eyes White Dragon obliterated me! I was surprised he didn't insist on dueling Yugi, like he always did. Nope, there wasn't a harsh word passed between them today. Jon and I went head to head in a thirty-minute match, which I won, by a nose. Espa and Yugi were next. Yugi won it pretty quickly. I wasn't surprised. By that time, Seto seemed pretty anxious to watch the large screen TV in the field so we watched.

I could not believe my eyes at first. The news came on,and as usual, we were headlines ,but this time it was my picture, not Seto's that was on the screen, then…."The latest Kaiba craze has nothing to do with the popular line of Duel Monsters accessories on the market. In fact, this craze was not caused by Seto Kaiba, but his little brother, Mokuba Kaiba. Introducing, "Diary Pro 2000K"!" I stared, and gawked, then turned and hugged Seto so tightly.

You might've thought that would've been the end of the surprises, but no. When we were on the way to Sadie's with Yugi, and Tea, who'd joined us later, Seto had one more present for me. It turned out to be you, a portable version of the DP2000K. I'm so happy right now, I can't think of anything that would make this day any more perfect than it already is. Well, yeah. I actually could. Seto could let me stay home from school tomorrow. Slim chance of that though. Oh well.

Well, I'm home now, so I need to go get ready for school. I can't wait to show you off to Carolyn Skylar. She's such a show off. Now it's my turn!

Mokuba Kaiba Out!
