So here we are people, a prequel to "A Rival's Desire" couldn't help myself in writing this.

Anyways this takes place right after Duelist kingdom/ Virtual Simulator arc. (Not the Noah arc)

By this time Yami has already developed her body (Like what happened in Darkyami's and My story "Unlocking Her Secrets")

Anyways, here's the thing people, 'guys' if you are reading this, you might freak out.

Now yes, Yami is undeniably female in this fic. But as we all know she is dead.
However she has the ability to form a body. But it doesn't work like our body does, she doesn't have to eat, get sick or go the bathroom (yes i did just say that). But she can get hurt, though she does heal inhumingly fast.

For example someon broke their arm, that would take them around 6 weeks, well for Yami she would take 2-3 weeks to heal completely. She heals twice as fast as the regular human does. She also need to rest, considering how long she be outside of the puzzle, it would take a lot of energy.

Now here's the best part lol

She doesn't have all the organs (besides the heart, brain, stomach and lungs) of a female, but her digestive system doesn't work appropriately. That also includes her reproductive system.

So she doesn't have to suffer through the menstrual cycle. (Lucky Bitch)

Now also get note that this is Male!Kaiba X Fem!Yami, if you don't like then don't read.

So yeah, just letting you know.

"Anyways onwards!"


Chapter 1: Well isn't this Great...

It's never a normal day unless there is always a problem in the Kaiba corporation. The mere fact that the older Kaiba brother was ready to throw a chair at a window.

His hand gripped the phone dangerously between his fingers.

"Don't give me any of that bullcrap." He yelled, causing the younger brother to wince.

"You either get it done or not." What sounded like a man trying to plead with the CEO on the other line, only it seem to infuriate the owner even more.

Kaiba seriously wanted to throw the phone. "Not an option. Get the engine back running or consider yourself looking for another job." He said before slamming the phone to the receiver.

The younger Kaiba looked at his older brother, his shoulders tense. "Nii-sama...?"

"Forget it Mokuba, it doesn't do any good to talk about it." He said his eyes moving back to the laptop that remained in front of him.

The younger brother only looked down. "There could have been a reason." He said.

Kaiba looked away from the screen, his blue eyes facing grey ones. "If there has been then simply the motor could have been turned off before it malfunction Mokuba."

The raven haired 12 year old sighed. "I guess."

Kaiba didn't mean to come off as rude, but the mere fact that a whole 5 months of work could go to waste because of one idiot's incapability to shut off a machine before it had a meltdown. It doesn't take rocket science to know that!

Mokuba gave his brother another look, he was about to call him again, that was until a certain ringing sound came from the phone. The older Kaiba didn't look at it when it picked it up.

"What." He scowled.

The younger Kaiba couldn't hear the person's voice, but the change of look over the older brother, made him wonder what news came along.

"Bring her right up." Was all the CEO said before hanging up the phone, a bit softer than the last one.

"Who is here?" The 12 year old asked.

"Yami Muto." He said before furiously typing on his laptop.

A large grin appeared on Mokuba's face. Kaiba would have indeed smirk at his brother's reaction, if it had not been for the scheduled duel that was about to happen. He knew that the younger boy had gotten a liking to the duel queen. Kaiba knew that there was no way that he could hide it that his younger brother had the smallest crush on the older girl. But for the most part, he would never let his younger brother get into a relationship at all. And with his rival no less. (note 1)

"I'll bring her in." The raven haired boy said running out of the room before the older Kaiba can even speak.

By the time Kaiba finished with filing and saving the information needed, he shut the laptop off and pulled out his deck. As well as a large metal briefcase. The door opened, as expected the female duelist walked in.

Kaiba took one look at her, noticing that instead of her usual attire, she decided to wear a black tank top with a white shirt that fell off her shoulders, matching with what looked like a darker, longer version of the Domino High School uniform skirt, with an ornaments of belts and bracelets, and of course her millennium puzzle, or whatever she called it.

"So ready for the duel?" She asked, a hand on her hip.

Kaiba said nothing as he simply brought out the metal briefcase. Causing his rival to raise a brow.

"Catch." He said chucking her his invention.

Yami caught it in one hand, taking a moment to look at it. She didn't have to guess that it was something related to duel monsters. She saw the white machinery seeing 5 slots and what looked like a deck holder.

"Another version of your duel disk?" She asked giving the machinery another look.

"Well at least you understand it." He stated.

Yami placed the duel disk over her wrist and added her deck to the deck holder. Like if she knew what disk inside out, she needed no instructions as to how to use it. Which was a good thing since Kaiba had no tolerance due to the time.

The duel went as expected when it was down to final turns with Yami holding Dark Magician and Kaiba has his Blue eyes.

Despite of which, when Yami ended up using spellbinding circle and equipped her magician with Book of Secret Arts. Ending the duel right there and then.

Kaiba growled internally. Another time, another day he ended loosing. "Another duel." He commanded, but the tri-haired female shook her head.

"Sorry Kaiba, but that was already the third duel in role. I promised you one duel and I must be going home. I promised Yugi that I would be helping with the shop." She said.

"It's the same excuses with you Muto. Always needed to help around." He said crossing his arms.

Yami paid no mind to it, after all she could actually give less of a rip about what Kaiba had to say at times. His stubbornness really did get in the way, especially when it came to his dueling and personality. But that didn't make him any less than a honorable duelist, one of thing that she sincerely did respected him about.

"Well in other cases I mostly would agree to stay, but this time I do need to go." She said not looking at him.

Kaiba sighed. "Fine, but tomorrow same time." He said, there was no way he was going to let this girl avoid the challenge.

"Fine by me." She said already making her way out.

But the moment she decided to take her first step the lights suddenly went out.

"What the?" Kaiba turned around, making his way towards his desk. He pulled the phone, but even when he did, the usual sound that phone would make to make the call wasn't present.

"You got to be kidding me." He spat.

He pulled out his personal phone, he dialed.

"What is going on?" He yelled the moment his brother answered.

"The motor shut completely off Nii-sama." Mokuba answered, the sound of men yelling and working rapidly could be heard in the background.

"How long will it take to re-operate." Kaiba demanded.

"It's uncertain, but they will be getting it back on!" He called.

Kaiba shut his phone shut, his face obviously pissed. "Well this is just fucken swell!" He said angrily. "When I find that man, he is getting his ass thrown out."

Yami crossed her arms, leaning against the wall. Well there was no way she could be able to make it out. She was at the top of Kaiba Corp and the elevators were completely shut down.

A long sigh escaped from her lips. Her hand went to her second deck holder, pulling out her cell. Thankful that she remembered to bring it.

"Yugi." She called. 'I'm going to be late."

...

"No everything is fine, it's just that Kaiba Corp suddenly lost power, I'm sorry that I couldn't make it."

...

"Will you fine by yourself, I could call Anzu to give you company."

...

"Alright if you say so, just be careful; I'll make it when I can, okay."

With a single snap she closed the phone after her brother understood. At least Yugi wouldn't worry too much now as to why she was late.

Her hand moved to her forehead wiping the sweat that started to form there. Boy was it getting hot.

She turned her gaze the corporation owner, seeing that he now seemed to calm as much as he could muster. Thankfully there was windows in the background giving the natural light, so it wasn't entirely dark inside the room.

The crimson eyed female could see the sweat that started to form on his forehead as well. Great... it really was getting warmer by the second.

"Well, until they bring the power back we're pretty much stuck here."

Yami sighed, crossing her arms slightly tighter. "And I'm going to assume that we can't even duel?" She asked a bit hopeful that the answer was no, at least it would be a way to pass the time.

"Without the satellite power there's no way we can." He said irritated.

"Well, aren't we lucky." She said sarcastically.

"For once I agree with you." He said snidely.

The girl didn't react, she turned around, suddenly finding the couch rather interesting. What seem like hours passed, and no progress of the engine starting to regain any power seem like a millennium.

Yami took another look to her phone, seeing if Anzu had responded to her text, but nothing so far. It seemed to be the only way she would be able to pass the time. At least Anzu could keep one interested for a while.

"It seems like they aren't doing anything." Yami muttered.

"I wouldn't be complaining." Kaiba said, looking up from his book, thankful that at least he had a reason to finish it.

"I wasn't even." She said, her eyebrows narrowing slightly.

The CEO shrugged his shoulders, he rather didn't care what the girl did, as long as she didn't cause any irritating or major problems. But mindful, he knew that the other duelist wouldn't even bother to move from that spot.

He heard the other sigh loudly, making him look at her, he felt himself prolonging his look when he saw that she had taken off her loose over-shirt, only leaving her in her black tank top that really accented her upper frame.

Kaiba blinked, has Yami always have that frame? Feeling his face go a bit warm, he quickly removed his eyes from the girl. What hell was that?

When he turned back to the girl, he saw that she was indeed looking back at him.

"What?" He demanded.

"Nothing." She said crossing her own arms. She noticed his face, seeing it turn pink slightly.

"You alright?"

"Yes." He hissed, turning away from her.

A playful smirk appeared on her face. Oh, she knew this. But as she was about to respond, she felt something spin inside her.

Kaiba didn't bother to look at her again, but when he heard another sigh, he turn to her direction for reason unknown, he didn't bother to look away, seeing how the girl slump against the couch.

"Hey, you fine?" He asked, trying not to sound concern.

"Yeah." Yami rasped, when was the last time she drank any fluids...?

Yami closed her eyes, noticing how hard it was to open them again.

"Hey, Yami." She heard Kaiba's voice, her eyes open halfway, when did Kaiba get closer?

At that moment she felt a slightly cooler temperature touch her forehead. It felt nice...

Kaiba eyes widen slightly momentarily at the feeling of the girl's forehead. "The heat really got to you." He said removing his hand.

"Dunno... what you're talking about." She said, a little quieter than her rasp.

The CEO took a good gander of her face seeing how it started look pinker by the second, especially at the bridge of her nose. It almost look like she was blushing.

*This is not good...* He thought taking a good look around. "Come on." He said, grabbing her. Yami barely registered what he was doing before she found herself on his back. Her face reddened a bit more at the contact.

The CEO opened the door and walked out, feeling that it was the smallest amount cooler than how it was inside his office, but he didn't bother, he needed to take her quickly, there was one place he knew would help her.

Thankfully they made it in a few minutes, as he placed her on break room couch as he pulled out a rag and added water on it.

"Why are you doing this?" The girl ask taking a long breath feeling the temperature change.

Kaiba shrugged "Can't have my rival passing out on me."

Yami leaned back against the rather comfortable couch. Her shoulders tensed slightly when the cool rag touched her face.

"Do you ever relax?" He asked, only the slightest amount of annoyance dripped in his voice.

"I can ask you the same thing." Yami countered, before a small cough followed.

Kaiba sighed when he went and pulled out a plastic cup, filling it with water and handed it to his rival.

"Thanks."

Kaiba crossed his arms leaning against the wall, when did he started to even care?

The color on her face paled a little, enough to keep her from becoming delirious. That was good, he couldn't deal with a loopy female around his hair.

"You know you're being rather nice."

The taller duelist shrugged, "Again can't have my duel rival pass out on me. I don't want to be responsible for the fact that Yami Muto passed out over a little heat on the news tonight."

At this the tri-colored haired female glared.

Kaiba crossed his arm, matching her expression. "Just saying."

"You know you don't have to be an ass about it. Would it ever kill you to at least answer without a sarcastic or arrogant tone for once." She challenged.

"Do I look like I care." He said dryly.

"You know what, I'm trying to be thankful, and it looks like you can't even accept it without your ego." The duel queen responded crossing her arms.

"Well it looks like your better." The CEO said snatching the rag away from her forehead. A crimson glare followed the moment he did.

Yami turned away from Kaiba. "I give up."

Kaiba just followed her pursuit and looked away. Both of them looked like children, but they didn't care.

"You know what, I'm going, I'll take the long way if I have to." She spat, however the fact that she recently had her head spinning, came back to her hard. And before she knew it she was falling forward.

Had it not been for Kaiba's quick reflexes she would have fallen face-flat.

"You can't even get up for a moment before you end up falling down." He said, a small mocking tone in his words.

Yami simply had enough, she stood up, but the dizziness still haven't gone away when her legs seemed to have buckled under her. Again if Kaiba had not been holding her, she would have fallen.

A smirk appeared over the CEO's face. "Looks like I still need to help you out."

Yami closed her eyes harshly. *Why this guy...*

"So much for being able to hand things on your own. If anything y-MPH!" Kaiba's eyes widen the moment he felt hands tug him down.

There was a brief moment until he felt lips on top of his own.


So yeah, it was getting rather long, so I decided to make it into two chapters.

You get the idea lol

Yeah, this is an AU of the story "Unlocking Her Secrets" the mere fact that I love this couple as much as the next Prideshipper, and it made me write this little series.

Yes you heard me right. I am writing a small AU series of Fem!Yami X Male!Kaiba from "Unlocking Her Secrets"

Well that's, that.

Now for the...

NOTES:

(1) Before you guys start asking, no I do not ship these two, either gender or AU age, what-so-ever. I always assumed that Mokuba would always have some kind of attachment to Yami after well, everything Yami has done for them you know. So honestly I couldn't help but do that. But no, Mokuba isn't going to be in relationship with fem!yami at all.

With that said, see you guys in the next chapter.
