"Human experimentation", A forbidden taboo practiced in secret in order to achieve a particular goal, or for the sake of research. While finding a solution to their twisted goals, or sometimes even ones for the sake of medical miracles, they sell their soul to the devil or the creation of one. The test subjects used are usually alive and live in harsh conditions, occasionally for the sake of Human evolution."

"what does it mean to evolve?" a young boy with white hair mixed with thin green highlights holding a science book questioned to a young researcher.

the researcher looked at the boy and smiled.

"Would you like to find out?" The man joked.

the boy smiled and laughed.

"Haha. that's funny. Mabie one day you will finish your research and I can see a real dragon!"

The man looked back at his research and smiled.

"I told you, It will only be solid vision." He replied laughing.

"Aww...but I wanted to see a real dragon..." the boy pouted.

"Maybe one day we will have real dragons zarc" He replied to the boy

zarc Smiled.

"Promise me, Leo?"

Leo kneeled down to the boys level.

"I can't make any promises, But I will do my best? okay? in the meantime, you and Ray be good, while I get back to my research You make sure Ray doesn't get in trouble. Use the buddy system going home okay?."

Zarc nodded and began to head towards the door, shouting

"Remember when you finish your research I wanna be the first one to try it out!"

Ray followed zarc pouting.

"No fair! I wanted to be first." screamed an angry Ray, earning her a ridiculous face from zarc in response.

"bleh! Only if you can catch me!"

Ray screamed and began to chase the boy out of the house.

"It must be nice to be young again." Said a familiar voice.

"Yushou!" exclaimed Leo who was surprised to see him.

"Any luck with this machine?" mused yushou knocking his hand against the glass of a bizarre contraption, that Leo was working on.

"Ah, No, I'm becoming rather desperate too. I really wanna figure out a way to make the children happy. wouldn't it be amazing to see duel monsters in action? flying across the sky, or swimming in our oceans, where we can interact as if it was life like. but I can't get this darn machine to work. I think I'm missing a major thing. It's a damn pity to just abandon the project. If I do it right I could make a breakthrough, and then the money could go towards paying for my daughter's health issues." Leo replied sadly.

"You seem a bit attached to your daughter... It must be nice having children, you know I always wanted a son, But you know, I'm a bit worried about this concept and your well being, and maybe your attachment becoming too much. You haven't slept in days, and you barely touched your food. Plus your son, reiji has talked to me a bit, he seems to be concerned about you too. Plus, we know very little about the experiment you are working on. I think you should at least take a break."

"I appreciate your concern Yushou. perhaps your right. I have been becoming a bit obsessed with the secrets of how to get this machine to work. I tried many things. But so far All I have managed to do was to get the normal Holograms to work. I think there is something missing."

"At least eat something. I'm, sure there will be a solution, But don't get too worked up." Yushou handed Leo a plate of pancake omelet.

"Your wife makes the best omelets, you know that right?"

"Speaking of wives? how is yours?" yushou asked

"You know, lately, she has been complaining that I been working too hard as well. for a minute you sounded like her."

yushou Laughed loudly.

"Well, maybe that is a sign. take it from me and take the day off. go outside and take a walk. Look at the scenery. and then take a nap. maybe later I will come buy and try and help you figure out some things."

"Haha, fine fine, I suppose I should take a break," Leo said putting down a wrench and wiping the sweat from his face.

"I'm gonna take my leave," yushou said to the researcher waving as he walked out the door.

Leo followed behind shortly after, grabbing his coat, and walking out the door after locking up and placing the key into his pocket.

He began to head down the road.

~~X~~

"Tada~! check out my Odd eyes pendulum dragon!" Zarc pronounced proudly to a group of children behind a local duel shop who laughed at the card.

"Haha! That's the dumbest one you showed us yet! Look at its stupid face, with the multicolored eyes! at least that dark rebellion you showed us the other day was pretty cool!. At least it's not as stupid as starve venom." A snarky boy pointed and laughed at the monster.

"hey! I like this card. Don't laugh at my monsters. One day I will become champion and then we will see who is laughing!" zarc began to get angry.

Ray screamed

"You're stupid zarc!"

"Don't call me stupid Ray." zarc pouted.

"But you are letting stupid boys step on your dream!"

"What did you say?!" the other boy said offended.

"Whatcha gonna do about it?" Ray poked her eye and stuck her tongue out.

The other boy Began to cry and left.

"Haha shows them right!" said zarc laughing at the boy and walking into a man and falling down.

"Oww..." said zarc, staring up at the man.

the man just glared at the children.

"I'm sorry mr...uh sir are you angry?" zarc said sitting up.

Ray began to shake in fear.

"Watch out!" she cried as the man picked zarc up and knocked him out while another came behind and took out Ray.

"W-What's happening?" Zarc's consciousness began to fade.

"Call the Professor." said one man to the other.

"on it."

~~~X~~~

The professor was out at a local coffee shop as his phone began to ring.

"hello?"

"Meet me by your lab. or your daughters head becomes a part of our display. come alone. don't call the police."

Leos' eyes Widened as he dropped the phone.

"Sir, are you okay? You seem a bit pale." A concerned waitress scanned the researcher's face.

The man shook his head and pulled out his wallet setting the appropriate amount of yen on the table plus tip and bowed nervously.

"I'm sorry madam, I'm in a bit of a hurry now, I must leave, excuse me!" He cried out dashing towards the door, almost tripping over the stairs on the way out.

the waitress placed a hand to her mouth in response to the man dashing out.

"I hope that man is okay," She muttered silently before getting back to work.

~~X~~

Upon arrival at the lab, A strange man was hanging around outside of the garden, With golden hair, and strange attire, including that of a white mask.

The professor Dashed out of the car and tackled the man to the ground.

"It was you! Who are you? where is my daughter?" he screamed out at the man.

"Fool. Sit up. I am not the man who kidnapped your daughter. " the man, pushed the man off of him and picked him up as Leo tried to fight and struggle.

"Who are you then!?"

"My name is paradox, for the time being, I am only Here to observe. don't disappoint me."

"What does that mean?" Leo questioned with a pained look.

"Only time will tell" The man replied with a smirk before disappearing leaving a very confused and Upset Leo trying to decipher what he just heard.

"Who was that man-Agh wait never mind. That isn't important. I gotta find My daughter!" Leo muttered running into the building by someone hiding in the shadows.

"What do you want!?"Leo screamed.

The darkness was lit up by a strong glow, in the shape of a ring, slowly revealing a face of a white-haired youth, with an evil smile.

"My name is bokura. and you have something I want, why don't we make a trade?"

Leo glanced at the boy with widened eyes.

"What could you possibly want from me? "

"The completion of that machine and a little side experiment, And in return, your daughter remains unharmed."

"This sounds dangerous, What sorta experiment."

"Oh, just a little human experimentation. Nothing too big." Bokura waved his hand gesturing his comment.

"Why? for what purpose?"

"That information isn't part of the deal."

"No deal. I don't want any part of this."

"that's a shame." bokura replied pulling out a phone and dialing a number.

"what are you doing?" Leo raised an eyebrow

"Just texting your daughter telling her that her daddy didn't wanna save her and it was okay if her soul was taken from her body and eaten."

"wait! No, don't!" Leo panicked.

"Then do we have a deal?" The boy smiled.

"As long as you don't hurt my daughter."

~~X~~

Bokura led the professor to the lab where zarc was strapped to a table, with a gag in his mouth, his screams muffled by the object.

"Zarc!" Leo Gasped.

"Heh, Isn't it zarc himself who gave permission to be experimented on?" Bokura shook with laughter.

"What are you saying?" Leo shook his head with fright.

Bokura began to imitate zarc's speech.

"Remember when you finish your research I wanna be the first one to try it out! Bwahahahahhaha! How precious."

Leo narrowed his eyes and went to go punch Bokura, but the boy disappeared and reappeared behind him.

"I wouldn't do that if I were you...It would be a shame for your daughter..."

"Fine. What do I need to do?"

"you are missing a key ingredient for your "solid vision" right? what if its because you can't replicate solid vision because you can't replicate something without a sample of what you mean to replicate... A living creature."

Leo raised his eyebrows until he realized exactly what he needed to do.

"In theory, that could work" he replied receiving an alarmed response from zarc who shook his head, with muffled screams.

"I'm sorry zarc... forgive me, in order to save my daughter... I know what I need to do... "

Back to reality as Leo was telling his story, there was a look of horror On the faces of the audience, where even the four yuboys who were seemingly preoccupied with their own desires toward each other were trying to take in the awful things they heard.

~~X~~

"Bokura... Was the one, who instigated this?" Atem shook with anger upon hearing this

Yuri Who was freed from his shackles lunged at Yugo Who was shaking from fear and began to bite the side of his neck roughly as yugo screamed in pain. taking one hand and placing his fingers against Yugo's shaft and slowly rubbing as yugo moans in response.

"You are going to be my pet... and I don't forgive disobedient pets." He whispered in Yugo's ear and biting the end of it roughly as a gasp escaped Yugo's lips

"N-No... Stop..." Yugo moaned.

"I bet you thought I was gonna go easy on you. But if I have to endure this, So do you.."

"Pl...please s..stop" Yugo began to cry out.

Yuri twisted on Yugo's nipples, as yugo cried in pain.

"I told you I don't forgive disobedient pets that easy.. now wag your tail and bark like a dog."

"I don't want to." Yugo cried.

Yuri smirked and pulled hard on Yugo's dick as yugo cried out.

"W-Wan Wan!" Yugo barked hesitantly and quietly as his demon tail waved from side to side.

"Louder I can't hear you!" Yuri yelled.

"Wan wan! " yugo responded as tears fell from his face.

Leo narrowed his eyes.

"Sick. He's actually enjoying this.."

Yushou shook his head.

"I don't want to hear you say something is sick when you were the one who made them do this in the first place..." reiji replied and grimaced in disgust, Knowing that this was the man he called father.

Yuya shook in fear at yuri's sadistic ways of torturing his partners, knowing he and yuto were next in line.

Yuto placed a hand on yuyas face It didn't matter how horny both of them were, how drugged up they were, they both would try and get through it together, as they were more than just sex partners. Yuto tried to reassure yuya, that even if Leo was the one who caged them up, they needed to have the sperm of their counterparts to have their children. and after that, they could figure out a way to escape afterward.

paradox narrowed his eyes.

"So far, to me, it seems you are trying to shift the blame purely to bokura Leo. and while it is true, that he was the one who started it. You Seem to be leaving out your portion of the blame. And if you aren't careful I may decide, the world isn't worth living in... "

"I didn't finish my story yet..." Leo looked down.

"Good then continue.." Paradox gestured.

"At first," Leo began.

"At first It was me only following orders.I experimented on the boy, And it was by no means something I was proud of. the experiments were painful and awful. I thought I'd try to ease the pain and suffering by making him forget. so there were times I'd mess with his memories, using the complex knowledge I had, sometimes the memory erasure would work, but it was unstable, and the boy grew up with many problems. But after 3 years the machine was working, but I wasn't satisfied. I wanted more. I went insane. And then I began to wonder if I could merge a human and a monster. And I remembered the boy had four cards in his possession...

What if I could create what no man has done before. Human evolution. I had sold my soul to a Satan, by trying to resurrect him. What I created was no longer human, I created a demon. a monster. With a tail as black as my soul, and wings that pierced the night sky with their beauty and sadness and horns that would tear the boundary of human and beast, the boy was reborn.

But I should have known what mess I had gotten myself into. I had to hide what the boy really was. But that wasn't the end.

among the years I had been working with the boy, as promised I let him be the first to try out my system, and as a result, he became a skilled duelist, as one of the things He did in his spare time was to enter tournaments. He rose up to the top with his monsters, riding them into battle, Dark rebellion, Odd eyes pendulum dragon, clear wing synchro dragon, and starve venom fusion dragon. He was unbeatable.

Meanwhile, my daughter was allowed to live with me as long as I didn't disobey bokura b ut she was convinced something was up.

One day zarc broke loose. Beyond my control, as his memories were no longer able to be erased, He was angry unstable And looking for vengeance against what I have done. I was a fool. I created a monster.

as the screaming crowd cowered in fear at the sight of a demon, He summoned a dragon who's power was enough to destroy the entire world. A dragon by the name of "supreme king zarc"

In my desperation, I had created a weapon to destroy him. and as I could no longer be forgiven, I would use my own body as a sacrifice.

But to my surprise, and horror, My own daughter, stole the cards and sacrificed herself. I blanked out And awoke In an area I didn't recognize.

Perhaps this was my punishment for playing God. the place I landed wasn't heaven or earth. perhaps I had landed in my own personal hell. "
