A/n: I wanted to make a Yugioh fanfiction again forever, but I didn't have a clue until now on what I should do about it. So well, I figured out this idea somehow. Anyways you probably want to know some things before this.

-Somewhat AU in terms of past events things from the manga and the show have happened in this...you'll understand as I go.

-Supreme King (Haou) still exists. (but he is inside of Judai) as part of him.

-Koyo does exist in this, but he is still in a coma and Judai has lost his memories of him. (For the most part)

-Judai's past:

(This is AU in terms of his parents and things). He was raised by his mother alone until he was 5 years of age. She died unexpectedly the night Judai met Koyo. After her death he was sent to live with his father, Seto Kaiba. His father was shocked to know that he had a son, never knowing about it before. Apparently though it happened when he was in High School, his mother running away from home and having him. She raised him as best she could while hiding his father and his past form him.

He was born when she was 15 years old... And his father was a year older than her at the time. Meaning his 21 year old Father was raising a 5 year old. Yeah, not the perfect picture there. In fact, because he was so busy he spent most of his time with Yugi, Tea, Tristan, and Joey as well as Mai and Duke. When Judai was heading off to Duel Academy, he went under his mothers name as to not be seen as a "rich idiot" as he refereed to them as (which often got him yelled at by his father at parties). He choose to bring his own hero deck with him to the school, but he had Koyo's stashed and ready to use when he needed to use it. During his first year at DA, he suffered a head injury during one of his "nature" hikes. He doesn't remember it, and he lost a lot of his memories during that time...

Judai's gift:

~A secret. But I can say that he is the reason for many...strange things happening. Only him, and a handful of others know about it. But not even he knows what his gift truly can cause, only the others that know...you'll understand as the story goes on.

Alright so I think that is all, and truthfully you don't have to read about Judai's past, but I put it so it explains things. Also yes I know it seems weird for a 21 year old to have a 5 year old and not logical seeing as it is Kaiba. We will go with the story of drinking alcohol for the first time and that happening...alright? |D...yeah that works...just go with it...

Set in season 3, alternate.

A Duelists Haunting Past

01

My Father and a Past Friend

AU somewhat. Judai lost patches of his memory during the first year at DA. After that there were gaps in his memory, and a lot of things are forgotten, and probably lost. Then, something happens. An old friend turned foe has come back to the Academy to take Judai back... But his past is much deeper than any of them actually think. And he has a special gift that could endanger them all.

Judai personally was sick to his stomach knowing that tomorrow was parent's day. All students were to call up there parents and ask them if they could come to the academy on such a short notice. Many of them couldn't already, so it was up to the kid if they came to school if the parent was not able to. For Judai though, he knew for a fact that his father would be there. Which was already annoying enough. Maybe it was the fact his Father was going to be there without him calling. He owned duel academy after all, he would already know. Judai didn't have to call him, and honestly he didn't want to in the first place but...he was kinda stuck here.

"Couldn't you get a hold of your parents Aniki?" Sho's voice snapped Judai out of his thoughts and he sighed.

"Haven't bothered to call. There probably on a business trip again." It was half the truth, his father seemed to always be off on trips when Judai called, and that or he just didn't answer. His mother would never answer...and no one needed to know why. Judai wanted to keep that secret hidden, more so because he could hardly remember what exactly happened to her...

"Aniki, you should at least try. I'm sure you want to see your parents again." Sho frowned and Judai let out a small sigh, looking over at the other.

"I don't know Sho, I really don't." He responded softly. "I just don't feel like calling them and being disappointed...I don't need to see them as well...it's fine."

Sho sighed once more. "Judai you never call them, never write letters, nothing. You need to learn that they do care about you...you should probably call them or something at least, not just for parents day."

"I don't need to." Judai was a bit harsher with the reply this time. Sho blinked, feeling like he struck a nerve about something.

"Judai is there something about your parents we don-"

"Sarge! Sho!" Kenzan promptly busted the door down, eyes wide. "Seto Kaiba is gonna be here tomorrow!"

Judai grumbled under his breath, trying to ignore the fact that his father was indeed showing up tomorrow. Great. Just great.

"He's apparently coming over to talk to the students and parents. It wen't from a no show day to a full house! I mean Seto Kaiba is coming to the academy to talk to us! How special can that be?"

"Very, considerin' he never showed up to any of the other academies." Another voice commented and Judai blinked as he had an arm around him.

"Johan." He blinked before he smiled a little, chuckling. "You never seize to amaze me, just appearing from nowhere."

Johan just smiled, moving a strand of blue hair out of his face before yawning. "Gah." He shook his head for a moment, Judai blinking at him before realizing something.

He was trapped.

Crap.

Judai swallowed. "Sho I'm not going to call my parents, even if I am trapped here."

"Judai." A stern voice made him swallow, he suddenly realized that Asuka had her arms crossed and was staring at him, a look Judai knew all to well. One of the looks that told him that there were no ways out. "Sho is right, you need to call your parents. He told me about it, and I agree. So tough it, we are all staying here and forcing you to call your parents."

"Asuka please noooo." Judai begged, trying to find a way to get out of this mess. He couldn't call his Father! That would end in disaster but...

Somehow, he was now sitting in front of the computer, a ringing sound sounding from the machine. Judai wanted to get sick, knowing for a fact that his Father would answer, and then the secret would be out. Gah. Great.

"You have contacted Kaiba Corporations, what is your call for?"

"...Judai why did you call-"

"Judai Yuki." Was all Judai said and then there was mad shuffling.

"O-of course. I will c-contact Mr. Kaiba right now sir."

Another ringing sounded, and Judai sighed. "You'll understand soon enough. But please! Keep this secret between the five of us!" He begged.

"...what secret-" Sho began before there was another voice.

"Judai? What is it?"

There were several thumps from people hitting the ground in that moment. Judai sighed then looked at the screen with a weak smile. "Er...hey...Dad." Judai chuckled nervously, glancing down to his friends that were staring at him from the ground like he was insane. Well...Asuka and Johan were. Sho and Kenzan had knocked themselves out from shock.

His Father looked around the room, glancing at them all before sighing. "What did I say about calling when people were around? This was supposed to be a secret Judai."

"It's not Judai's fault!" Asuka defended then. "I was the one that told Judai to call his parents about tomorrow...I never thought..." She trailed off.

"...I understand. Now I must get back to what I was doing before. Though, Judai, why have you not called before?"

Judai looked down uneasily. "I...sorta forgot to and then I thought against it and...yeah..."

"Right. I'll see you tomorrow. Goodbye."

The screen shut off and Judai sighed lightly. "Now do you see why I didn't want you to meet my parent...?" He groaned.

"...don't you mean parents Judai?" Asuka frowned and the boy looked down.

"My mom died when I was five, so...parent is right."

"Oh Judai...I'm so sorry..." He felt arms around him and he just relaxed, letting Asuka hold him close. "I never...I never should have said anything..."

Judai sighed at that and then smiled up at her weakly. "It's fine. We just need to keep this little secret alright? Johan that goes for you as well. I can just pray that Kenzan and Sho think this is a dream when they wake up." He groaned. Asuka chuckled before hearing her friends call.

"I got to go, I'll see you tomorrow Judai!" She called before running out of the room, smiling lightly. Oh Judai...I wish you knew how I felt about you... She thought sadly as she ran over to her friends who were waiting with smiles.

Judai watched her leave with a small smile before blinking. "Johan?" He questioned the blunette who tilted his head at the use of his name.

"Yeah Judai?"

"Would you...mind staying here tonight? I...after that memories are going to come back that I don't understand."

"Of course Ju-chan."

Judai blushed and looked at Johan. "I AM NOT JU-CHAN!" Johan laughed at the outburst and smiled then.

"Oh yes you are!"

The punch to his face was well worth it.

Judai sat silently as he looked at the boat with all of the parents. He sat on the cliff nearest to the boat, but he didn't move from his spot. He was angry and upset with his Father at the moment. A last minute call and he had to cancel today, meaning after all of that Judai had to wait another year before he got to see his damned Father. A year to see his own father! It was making him beyond mad, he only felt this way once before mad.

"Judai, fancy meeting you here." The voice was soft and Judai about fell off the cliff before he turned around. He smiled weakly.

"Hey Serenity." He said to the woman as she took a seat besides him. "What are you doing here?" He questioned her, knowing full well she had no reason to be on DA's island.

"Oh? Your Father sent me. He decided someone from your past better talk to you after the...incident yesterday." She murmured.

"So you heard about the dream already?"

"Judai, your Father keeps tabs on your dreams after the last...incident you had. Last night, he got so freaked out he was forced to take today off. He lied to you so I could tell you about it. Let's just say that Mokuba had to force him to rest because he was fretting over...the incident."

"My Father? Worried?" Judai snorted before he sighed. "I get that though, after that...yeah...I understand it." He closed his eyes and sighed. "I didn't do anything this time, because she's no longer here but...I have a bad feeling that sooner or later she will be..." He murmured. "And when that happens..." He shuddered. "I know nothing will go right."

"I know Judai." She put an arm around him and ruffled his hair. "But remember, all of us are here for you."

He smiled weakly. "I know Serenity. I know." He murmured and looked at her. "Thank you. I did need to let that out..." He paused, before chuckling. "Hey, have you ever wanted to pet a crocodile?" He questioned.

She raised an eyebrow. "Do I want to know why you asked that?" She asked back and he smiled before turning around.

"Hey Karen!" He said, smiling lightly at the croc. Karen just blinked at him and stayed still, letting him run his hand down her scales. He lifted Serenity's hand and ran it down Karen's back. The woman blinked before she smiled and hugged Judai.

"Oh Judai! You're just like the five year old I remember!" She smiled and he laughed.

"Yeah, but I was a mayhem child back then, I can't even count how many times I was grounded in my first year!"

"I do admit Joey and I helped you get into trouble though." She shrugged and he smiled.

"True. You did. But oh well." He stood up. "I better hurry to my friends! If Karen has found me it won't be long before-" She caught his hand and smiled.

"Judai, I'm going with you. Alright? I would love to meet your friends, and besides I want to know what they are like. Since none of your friends know we can go with me being your mom or sister-"

"How about long lost friend that came here with her parents to see a relative?" He asked.

She chuckled. "Oh Judai, you and your thought up realities." She smiled. "But that works quite well." She nodded at him, telling him to lead the way to his friends. Judai smiled back at her and silently lead her back through the forest with Karen following them both silently.

"I found you Judai, and this time...I'm not letting you run away from me, or seal me away like you did before. It's not going to happen this time. This time...I will be in full control over you...I won't be the darker half soon enough!"

The flames erupted around him, and he let out a small cry. The little boy ran for his mother's room, trying to get her to wake up to save him. "Momma!" He yelled, but then his eyes went dark as he saw what lay before him. A burned corpse. His eyes widened in horror and he ran for the front door, screaming... All the meanwhile, a dark figure watched the boy run, chuckling softly before closing it's wings and moving into the flames...vanishing without a trace.

"Perfect." The creature murmured, the last trace of the creature being there.
