"Akaba!" Shun Kurosaki roared as he stood before the man who had been the source of everything that had gone wrong, who was the one that had destroyed his home, taken his sister(said sister being in a tube next to three other girls who shared her face), his best friend(Who was currently stuck inside the head of his comrade. "Your scheme ends here!"

"It does not, boy," Leo Akaba said back. "My plan is coming to fruition; the Arc-V is ready soon; the worlds and my daughter will be whole once more. And there is nothing you can do to stop me; the Demon has already failed."

The madman held up a card, and… Shun's heart stopped beating as he saw the image of Yuya in it.

"Yuto…" His voice was a whisper, and then the rage, the anger, the hatred returned. "You monster!" Shun roared as his Duel Disk activated.

"Hmm, it seems that I still have to teach lessons today," Leo Akaba activated his duel disk. "Duel!"

Shun Kursoaki LP: 8000

Leo Akaba LP: 8000

And what Shun experienced was probably the toughest and most difficult duel of his entire life, as if with every inch he gained, he lost an entire foot's worth of progress.

His birds were destroyed, and his spells and traps were denied.

"Are you done with this pathetic display," Leo Akaba spoke as Shun lay on the ground, his body battered and bruised.

Shun Kurosaki LP: 100

Leo Akaba LP: 4000

"I… I am not done until you are taken down until you are card in my hand that I can rip into pieces," Shun said as he got back up on his feet. "It's my turn now."

"Then draw your last pathic card, Kurosaki," Leo Akaba said. "There is nothing that you can do to battle my ultimate Sacred Beast."

Shun glared at the fusion monster that was bearing down on him.

"My deck has no pathic cards; I will show you the bond that I share with… the ones I love," Shun said. "I draw. I activate Foolish Burial to send Raidraptor – Bloom Vulure to the Grave, and since I control no monsters, I can Special it and another Level 4 Raidraptor from my Grave, and I choose Raider's Wing."

The two mechanical birds appeared on his field.

"And what XYZ monster do you have left?"

"This," Shun replied. "I create the Overlay Network by Overlaying my Level 4 Raidraptor – Bloom Vulture and Raider's Wing, I XYZ Summon! Come forth! The manifestation of my bond with Yuto! Rank 4 – Raider's Knight!" Shun declared, and from the anti-matter portal, a dark knight riding an armored horse manifested. "And I will activate his effect by detaching one overlay unit, I can reconstruct the Overlay Network to XYZ Summon a Dark XYZ monster one rank-higher or lower, and I choose higher. Come forth! Rank 5! Raidraptor – Brave Strix!"

"And you repeat yourself over and over again, you XYZ users, rank-up over and over again, hoping that you arrive at a new self, a new world, that is foolish; only by fusion, by combining things together, can one create the world that one desires," Leo Akaba said.

"Screw that noise, that is the talk of someone who can't let go of the past, me!" Shun shouted. "I will continue to head towards the future, together with my friends and family. For unlike you, I have hope for a better tomorrow, and I will rank-up as many times as it takes to find the future where we can be all happy!"

At that, the world shook.

"What was that?"

"That was the Arc-V; the boot-up sequence has finally been completed. Soon enough. The dimensions will become one, and I will have my daughter back." Leo Akaba said, and Shun watched as all the tubes containing the girls started to glow as the now longer were visible.

"Ruri!" Shun shouted. "Akaba, I won't let you get away with this; I activate the effect of my Raidraptor – Brave Strix; by detaching an overlay unit, I can add a Rank-Up-Magic from my deck to my hand!"

And upon his declaration, Shun's deck shone with golden light.

"What is that?" Leo Akaba asked.

"Your demise!" Shun shouted as the card was ejected into his hand by his Duel Disk. "I activate the Quick-Play Spell Card – Rise Rank-Up-Magic Raidraptor's Force! With this, I can target two or more Raidraptor XYZ Monsters in my Grave, including one on my field, and I choose Rank 5 - Brave Strix on my field, Rank 4 – Raider's Knight in my Grave, and finally, Rank 4 – Force Strix, to XYZ Summon a Raidraptor XYZ Monster from my Extra Deck whose Rank equal the combined total Rank of the monsters I selected!"

"Wait, that is 13! No such Xyz Rank exists!" Leo Akaba yelled.

"Think again, you monster!" Shun shouted. "I XYZ Summon the manifestation of all my rage, all my hate, the embodiment of my very soul, my very being to stop you, Leo Akaba! Come forth! Rank 13! Raidraptor – Rising Rebellion Falcon!"

And from the heavens, through an XYZ portal greater in size than anything Leo Okaba had ever seen in his entire life, descended a monster that had broken every single rule that governed the existence of XYZ monsters.

It was an impossibility that should not exist.

Shun Kurosaki had manifested a being that could match, not exceed, the power of his Sacred Beast.

A god of his very own.

"Rise Rebellion Falcon's effect activates!" Shun shouted. "It will now destroy everything."

"Nooo!" Leo Akaba shouted as the Xyz monster glowed with a purple light that consumed everything.

And then things got weird.

"Hey, hey… hey, are you awake? Hello? Oh shit, are you dead?" A voice asked me, and that was strange; I was pretty sure a voice shouldn't be able to say that, considering that I was living alone, and I was also sure that I wasn't dreaming currently, as I very much knew that I was awake. "Man, and here I thought I had found a human that I could partner up with…"

And also, I was pretty sure I wasn't on my bed anymore.

Then I felt something smack my head.

"I am not dead, and I am up," I said as I quickly sat up, and I immediately regretted that decision as I ended up smacking my forehead against the person who had been looking down at me.

"Ahhh!" We both shouted in pain, and yeah definitely wasn't dreaming.

"Poplar!" A voice? Said in happiness, and I turned my head and to my right, I saw a pink furred? A creature was looking at me with a happy face, a giant ominous-looking eye stuck on its forehead.

An eye that I recognized.

I was looking at Snake-Eyes Poplar.

I turned my head, and on my left, I could see the person that I had head-butted currently sitting on the ground that I was lying on, who was currently nursing her forehead.

She was dressed in a black and red outfit that highlighted her rather busty body, and while most of her head was covered by her hood, I could still see silver-green hair. Which complimented her light-green eyes.

And while she wasn't wearing her mask, I still easily recognized her as Diabellstar the Black Witch.

"Sorry," I apologized.

"No, it's my fault," Diabellstar said as she got back up on her feet. "So anyway, human, you wanna partner up so that we can participate in the tournament circuit and get the Supreme King to grant our wish since you lack a Spirit Partner."

And all I could say to that was…

"What?"
