Author's note: Okay. I decided to try something else this time and create this chapter for the Yugioh Arc-V series. But I decided to do something...let's just say for the lack of better words...different. It will be the usual canon Arc-V series, but then it will turn to AU (Alternate Universe) later on. There are few reasons why am I doing that. One will be because of the Dimensional Wars and the other, Synchro Dimensions, as well as others which will be reveal later on. And considering the Arc-V series is still ongoing, the updates will probably be slow, compare to my other stories. Anyway, enjoy this chapter.

Disclaimers: I don't own Yugioh Arc-V.

Prologue

Somewhere in Miami City, specifically at the park where the river was flowing, a girl at age fifteen with blonde hair highlighted in pink was carrying a eleven-year old boy with red-green hair that almost resembled a tomato over her shoulder...Both were completely drenched from head to toe once the blonde managed to save her brother, Yuya, from drowning.

This was rather a long story. A moment ago, a group of bullies had gang up on the tomato head and started picking on him. All of a sudden, one of them just have to rip the pendent out of his neck and threw it over the bridge, which went into the water and washed away. Of course, seeing how that pendent is precious to him, Yuya made a brave, yet stupid choice of taking a chance to jump into the river to get his pendent back.

The blonde girl, Tsubasa, saw the whole thing, and her old sister instinct took over her and jumped to the river to prevent Yuya from drowning. What seemed to be a rush of few seconds later, Tsubasa managed to save him and carried Yuya, (who was coughing violently) to the shore, noticing that the kids who were messing with the tomato head were gone. The blonde girl sighed in annoyance as she gently placed Yuya on the ground. Under different circumstances, she would've teach those bullies a lesson or two for picking on her brother, but now, Yuya's life was at stake, so she knew she had to do the latter. Oh well, she'll take care of them whenever she sees them again.

Suddenly, Yuya's coughs started to cease and managed to croak out, "Nee-san..."

"Hey little brother. You're safe now." Tsubasa replied, feeling relief, "You're okay?"

"Yep. Just a little cold."

"Sheesh. Yuya, what were you thinking?!" Tsubasa yelled and took a chance to flick Yuya on the forehead. "You could've died, y'know! And all because of that pendant of yours?!"

"Ow! Hey, at least I got it back!" The red-green head boy held up a blue crystal pendant and smiled, letting the blue crystal swing around like an actual pendulum. The blonde girl stared at it for a moment and smiled. This pendant was given to Yuya as gift from their father, who went missing few months ago. And she was kinda glad that Yuya still kept it as part of memento. She missed Sakaki Yusho dearly, and still does, even after everything had have done for her when she was still a kid...

"Hey, Tsubasa!"

The girl snapped out of her thoughts and looked at her brother. "Yes, Yuya?"

"When do you think dad will come back?"

Tsubasa gave out an blank expression before glancing back at the scenery in front of her, where the sun was setting. "Don't know. I honestly don't know. Why do you ask?"

"Just asking." Yuya answered, keeping his eyes on the pendulum crystal. "But I hope he'll come back soon. I missed him so much already."

"Me too." Tsubasa said sadly. Then, the two siblings got up and head home for the day, preparing for the wrath of their mother's scolding once she sees them all wet.

My name is Tsubasa...Sakaki Tsubasa. My childhood life was pretty much a harsh one up until I was taken in by a married couple and a son whom I can finally called a true family.

I don't remember much of my early life, but I do remember that being constantly thrown around in the foster care and was treated badly, both verbally and physically. Why? I don't know, but I guess I would never find out anyway (not that I really care). And I also don't know much about my biological parents. From what I was told, I was found abandoned on the street as a baby and someone found me and took me to the nearby orphanage and was raised there. That thought alone, plus the fact that no one wants to take care of me, made me really angry and ended up having to fend myself. That was the time when I have a hard time trusting other people.

But that changed when a man named Sakaki Yusho and his wife came to the orphanage I was currently living and took me in as a new member of the family. Everything happened so fast, I really thought it was just a dream. But it wasn't.

But even so, I still didn't trust them. And that's because I had a feeling that they would eventually threw me away like all the other foster families did. At least not until Yusho brought me into one of his duels.

It was a greatest moment of my life. After seeing Yusho brought smiles to all the crowds as an Entertainment duelist, I felt like the world around me that used to be dull grey had turned into bright colors. Seeing all the Duel Monsters and my adoptive father performed and took to the sky, I have found myself smiling for the first time ever in my life.

It was kinda funny for me to think this, because all of a sudden, I wanted to become like my father...an Entertainment Duelist who can bring smiles to the crowd and achieved the impossible. But that dream didn't last very long after Yusho disappeared before one of his match, and everyone else thought that he became a cowards and ran away.

Of course, I knew that wasn't true. Yusho wouldn't run away like that, and I'm sure there was a good reason behind this. Even my adoptive mother, Yoko, and my adoptive younger brother, Yuya, thought so too. Though, Yuya ended up taking this harder than the rest of us, and he ended up getting bullied after that incident, leading me and couple of his friends to defend him. As for me, I kinda isolated myself and recently lost my passion for dueling, and never even attempted to enter the dueling tournaments. The only time I ever dueled was with my brother, few of my friends at the You Show Duel School, or whenever some other people forces me to duel them for their own amusement.

Even with all the obstacles coming around, I didn't back down from life. I decided to support Yuya with his dreams along with trying to find out what should I do from now on. And I knew someday my father would come back. But what I didn't expect was something beyond this world was about to happen that can possibly change my life forever...

Author's note: Okay, so you obviously know that Tsubasa is Yuya's sister, or rather adopted sister, and her origin is unknown at this point. And her passion for dueling has deteriorated. And it's not just because Yusho disappeared, but I'm still not telling you the other reasons why yet.

And some of you should already guessed where I got the title "Crossover" from.

Anyway, I will be continuing this depending on how many reviews this story gets, and again, this story may have slower updates than my other ones. I'll take any criticisms for this story, if anyone feel like some plots needs to be fixed.

Until then, R&R.
