Full Summary

The Darkness and the Light cannot exist without each other; Balance is what keeps everything in line but that balance has shifted, in favor of the Light. In order for Balance to be restored, Fate has intervened and two have been chosen to restore the balance.

Per Lily's Will, Harry Potter is raised by the sister few knew she had who lives in Japan, a country that the Dark Lord Voldemort never once looked at during the war. As futures are altered, Harry and his cousin by blood but brother by choice Jaden must find a way to become more than just pawns in an elaborate but dangerous game—a game in which more than just their live are at stake—or risk losing everything.

Notes

Okay, this is that HP/YGOGX crossover that I said I was going to try and do on my profile. It is set in an Alternate Universe (obviously [sarcastic drawl]) but will follow the events of the first four books of Harry Potter. Four GX characters will be magical and I will give you hints as to who those four characters are; Jaden obviously is one, the second and third are brother and sister and the fourth doesn't make an appearance in GX until season 3. I can say with absolute certainty that there will be NO Harry/Ginny in this story; I have decided to pair Harry with Alexis in later chapters (as in, in Part 4 or 5) and, as is said in the Update Note below and in Chapter 4, there will be Spiritshipping in this story. As it states in the summary, there is no bashing in this story. Here is the short prologue (I glossed over the legal matters since I'm no lawyer). I hope that you enjoy this story and reviews, as always, are much appreciated.

Update Note (10/3/2014)

I have changed my mind. There will be slash in this story but it will only be Spiritshipping (Jesse/Jaden). Please refer to the author's note I have at the beginning of Chapter 4 for the explanation as to my original intentions for this story.

Disclaimer

I do not own Harry Potter and I don't own Yu-Gi-Oh! GX and I am only saying this once so I will not repeat it in later chapters.

Prologue

A Late Sister's Request

Office of Lucas Bennett, Attorney of Law

London, England

Violet Yuki nee Evans gently rocked her son in her arms, the motion soothing her as she attempted to keep her emotions under control. It was hard to do as she listened to the lawyer read off Lily Potter nee Evans' Will. She and her husband had been asked to come to England one week after the deaths of Violet's younger sister to hear the reading of the Will. Lily had decided to write a will and submit it to both the magical government and the mundane government just in case someone attempted to stop the reading of the magical will; her husband only had a magical will though, which was why Violet wasn't hearing her brother in law's will. She did have to wonder why she and her husband were the only ones who showed up to the Will reading though.

Violet didn't know whether her sister was being paranoid or not but she knew that the Ministry of Magic in England may be inclined to do something to make sure their precious Boy-Who-Lived was placed somewhere where they could keep an eye on him. However, the Ministry couldn't interfere with mundane law and so if the will that Lily submitted to the mundane government's court system stated that her son was to go with one family then the Ministry could do nothing, except contest it and, even then, it was doubtful it would work.

"To Kaito Itsuki Yuki and Violet Senna Yuki nee Evans, I leave my love, that jewelry box for you Vi, you know which one I am talking about, and, with my husband James Charles Potter's approval, full guardianship of my son, Harry James Potter. I know that you will raise him to be the best man that he can possibly be and I feel that he would do well growing up with a brother in his life.

Under no circumstances is my son, Harry James Potter, to be given to my sister Petunia Lilac Dursley nee Evans. While I love her because she is my sister, I do not trust her to take care of my son and I trust her husband even less.

These are my last wishes.

Lily Iris Potter nee Evans."

"So I get custody of my nephew?" Violet asked once the lawyer—Lucas Bennett—put the will back into the folder he had taken it from.

"Yes. There are others listed but none of them were able to show up so, if you cannot take care of your nephew, I will contact them to let them know that they can," he replied.

"My husband and I live in Japan. Will that be a problem?"

"Not at all, Mrs. Yuki. Your sister wanted you to take care of her son and so custody will be given to you and that means that he can and will be able to go to Japan with you," Bennett said.

"That's good. Kaito, dear, what do you say?"

Kaito glanced at her. "He's family, Vi. And I do think Jaden will benefit from having a brother," he said.

Violet smiled, relieved that her husband agreed, though she wasn't completely surprised that he had. He was very big on family and Harry was family. "When can we take our nephew home?" she asked.

"We will just need to verify everything but you can take him home tomorrow at the latest," Bennett said.

"Where is he now?"

"He was likely placed with your sister Petunia as she is the only family he has in England at the moment. I can call them to confirm this. I need to schedule a time when they can come to the Will reading since they weren't able to make it today anyway," Bennett said.

Violet nodded.

Number Four Privet Drive

Little Whinging, Surrey

Violet was holding her son Jaden in her arms as she and her husband walked over to the ordinary house that was the home of her sister Petunia. Jaden was wide awake and looking around with wide curious brown eyes and Violet couldn't help but smile at her son before she gently handed him to Kaito and rang the doorbell.

The sound of a crying baby sounded in the room followed by a "Vernon! Could you get that? Dudders won't stop crying!" from Petunia's familiar shrill voice.

The sound of feet thudding against the ground came and the door opened to reveal Vernon Dursley, a heavyset man with a thick mustache. "Who are you and what do you want?" he growled.

Kaito raised an eyebrow at Vernon's rude tone.

"I'm Violet, Petunia's sister and this is my husband Kaito. We're here about our nephew Harry," Violet said.

"Oh right, Mr. Bennett called saying you would be coming by today to pick up the boy," Vernon grunted before he stepped aside. "Come in. The sooner we get him away from us the better. We never wanted him anyway. He was just dumped on our doorstep."

"Dumped on your doorstep?" Violet echoed.

"That is not right," Kaito said. "Someone should have come in and at least told you that he was only staying until everything was settled with his parents' wills."

"Well, he didn't. He just left a letter saying we had to take care of the boy. He didn't even bother on asking us if we could take him in," Vernon growled furiously.

"He?"

"Albus Dumbledore," Petunia said, walking over to join them. "He was the one who left the boy with us and told us we had to take care of and raise him."

Kaito shook his head. "The will clearly states that my wife and I are to be his guardians," he said.

"When was Harry left here?" Violet asked.

"The day after Halloween," Petunia said.

"And he said that you had to take care of him? It seems to me that he wasn't even going to bother on looking at the wills, or perhaps assumed that the will would name you his guardians. But it doesn't matter now. Everything is settled with the government. We'll need to get Harry a passport though, since he is leaving the country, but that shouldn't take too long. Can I see him?"

"He's asleep right now, so is Dudders. I just got him to get to sleep so try not to wake him up," Petunia said before leading Violet, Kaito and their sleepy baby Jaden up the stairs and into a room that Violet figured was the nursery. In it was a single crib in which two babies were fast asleep; one was pudgy with brown hair, his little hands clasping the blanket that was placed around him while the other was smaller with dark hair clutching at a stuffed black dog in his tiny arms.

"Here," Petunia said and Violet walked over to the crib before peering down at little Harry. She smiled before reaching into the crib and gently lifting the tiny baby into her arms; the baby stirred and blinked open brilliant green eyes, so like Violet's own and so like Lily's that Violet couldn't help another small but sad smile crossing her lips.

The baby looked at her before reaching out for the stuffed toy he had dropped. "Paddy," he said softly.

Violet reached back into the crib before picking up the black dog and handing it to Harry who wrapped his little arms around it and pressed his face into it. "Does he have anything we can take with us?" she asked her sister.

"Only that stuffed dog," Petunia said. "Now that you have the boy, you can leave now."

Violet raised an eyebrow but otherwise nodded. "We will be leaving right away," she said before she looked at her husband. "Come on, Kaito. Let's go."

"Your sister is such a pleasant young lady," Kaito said after they left the house and were heading toward an apparation point, sarcasm dripping from his voice.

Violet sighed. "She resents magic and everyone who has magic," she said. "Come on, let's get back to the hotel and get some sleep. We'll need to get Harry a passport before we head home."

"I can take care of that in the morning," Kaito said. "Let's get back to the hotel."

Violet nodded before looking at Harry. "I promise you, Lily, that I will take care of your son and do my best to raise him to be the best man that he can be," she whispered, feeling her magic swirl around her, binding her to her vow, a vow that she was determined not to break.

To Be Continued

A/n what do you think?

Blaze: that was the short prologue, introducing important people and things, plus including an adorable baby Harry and an adorable baby Jaden 'cause, come on, you gotta admit baby Harry is just adorable and I'm sure baby Jaden would be the same way

Darth: (rolls eyes) at least you aren't setting things on fire

Blaze: (sets Wormtail on fire)

Wormtail: AHHH! I'm on fire! (Runs around screaming)

Darth: I spoke too soon

Blaze: well, I hope you enjoyed the prologue. This story will be split into five parts, the first part will follow portions of Harry's and Jaden's childhood and will be the shortest (like only two, maybe three chapters), while the second part to the fifth part will follow books one through four of Harry Potter.

Darth: are you going to be doing the four seasons of Yu-Gi-Oh! GX?

Blaze: possibly. I'll see when I finish the fifth part and, of course, if my reviewers want me to then I may.

Darth: cool but what will you do for season 3? 'Cause you're going to be…

Blaze: shh! (Grabs Darth and duct-tapes his mouth shut)

Darth: mmmf!

Blaze: also, it is unlikely there will be many duels in the first five parts since it will take place primarily in the HP universe but I may include a few duels (the way I see it, it's practice and maybe my beta-reader for Shadow Rise will be willing to look 'em over if I do decide to do 'em) mostly because you can't have a Yu-Gi-Oh! (no matter which series) fic without duels.

Darth: mmf!

Blaze: I'm going to take that as an agreement. Well, I hope you enjoyed that chapter. Please review, as they are much appreciated.
