"Mokuba, the first robot we're making, to test whether everything works, will be a human."

Mokuba's eyes widened dramatically as those words were spoken but Seto continued. "I'm going to be creating a human A.I, most likely a teenage boy, similar to my age. Myself and the scientists working on this project have decided it will be the easiest to create, as the A.I technology for creating human like robots at the moment is advanced. But what I plan will take it to the next level. He will act, look and move like a human and from anyone else's perspective, he will be human, but inside, he'll be a robot."

Seto placed his hand onto the blueprints, hinting that his little brother should look, Mokuba glanced towards his brother's hand.

"Seto, are you serio-OH MY GOD YOU ARE!" Mokuba stared at the outline, noticing the teenage look of the figure. "Nii-sama, why?" He looked back at his brother, hints of worry on his face.

"Mokie, like I said, A.I technology is becoming more realistic every year, I want to be ahead of the game and create this so I can see whether making Duel Monsters is a realistic plan." Seto half smiled, rubbing Mokuba's back in reassurance. His smile faltered at the look of confusion that now was on Mokuba's face. "Don't worry, I haven't gone mad, it's an experiment, if it works, then 'great', if not, then I'll keep trying until I can make it work."

Mokuba's face fell back into a smile, he rested his head on his brother's shoulder. "Even if it didn't work, you wouldn't give up, would you?" He laughed when he felt his Seto's head shake, typical, he's thought of a seemingly impossible idea, and will not stop till it works, he thought, he then looked up at his brother then to the blueprints. "Why a teenage boy? Surely a kid would be easier to make?"

"Mokuba, most 'human' duel monsters appear adult, like Dark Magician and the Dark Magician Girl, and I chose a boy, mainly because I ..." He mumbled the remainder of the sentence. Mokuba looked up at his brother again.

"What was that?"

"I know more about the male body okay!" Seto half mumbled, half snapped, glaring at the floor to the left of him. His glare was broken by soft laughing from Mokuba. "What?" He looked towards his brother.

"Haha, oh it's nothing, that just sounded funny." Mokuba continued to giggle softly, until his brother's glare turned on him. "WHAT? It's not as if I've ever seen you with a girlfriend." In an attempt to rid the awkward silence, Mokuba quickly jumped off of Seto's lap. "So big brother, can you show me anything you've done so far?" He smiled brightly as he noticed his brother's discomfort. "I wanna see how long it will take too. You're not going to be stuck at work for too long are you?"

Blue eyes snapped up to grey ones, softening as they did. "I'll try not to be here too much, but this project will take months, so I'll be working more than usual." Seto quickly continued as he noticed Mokuba look glum. "But I promise I will try not to spend all my time at Kaiba Corp. I promise to spend as much time as I can with you." Mokuba smiled again, cocking his head towards the door and running out, hinting for his brother to follow.

"Come-on then brother, show me what you've done!"

TBC, soon! Promise!

Yeah, this is short, but it's just the build up to the main story, I'll hopefully have some more chapters up soon, depends how I decide how I'm going to do this.

The next chapter -or two- will be the actual project/experiment, then it'll continue from the prologue.
