Order VS. Chaos, Now, Become One!

(Um, as I mentioned before, this Zack is a clone, and other characters' Super Polymerization can't merge into worlds; at least, the game in the TV series never used Super Polymerization to merge into worlds. However, it's possible that Zack with the Chaos Emissary's enhancement can...)

In short, please look forward to the Yu-Gi-Oh! -Oh! collaboration episode a long time from now!

Heavenly Fire, unsheathed!

The blazing slash that could incinerate everything flew towards the pillar of light, only to be swallowed whole by the ferocious purple dragon.

"Well done, Voracious Poison." Zack praised it, then looked at the panting young knight with a hint of doubt. "Strange, I clearly reduced your health to zero, so why are you still alive?"

"Because I activated this Trap Card, 'The Final Road to Ruin,' and I won't lose the duel Zero Time. However, I will lose completely when your next turn ends."

This is one of the cards You Hui left for him in the Duel Disk. The card depicts a white-haired girl gazing at Earth alone from the moon, her golden eyes filled with despair.

It seems that You Hui already knew how terrifying Zack was. Could the messenger with "You" in his name that Zack mentioned be referring to You Hui?

Fortunately, he planted the Heavenly Fire Judgment - Oath of Protection in the ground. His steps were unsteady, but his right hand rested on the deck again. He looked at Zack with a determined gaze and said, "Come on, this is the last turn. It's time."

Black Seele's Affection Level: 65→75

White Seele's favorability rating: 60→75

"What foolish yet determined duelists..." Zack sighed helplessly, then his golden beast eyes gleamed with excitement. "Let's make the duel more interesting!"

"I haven't performed a Pendulum Summon yet this turn! Appear, my servants, Pendulum Summon!"

"O omniscient and omnipotent magician, who sees through time, reads the Stars, manipulates space and time! Descend upon me now, grant me your power! Appear, Star-Reading Magician!"

A sorcerer who seemed to be made of Stars appeared on Zack's field.

"I activate the effect of the Star-Reading Magician, liberating myself to banish the Four Heavenly Dragons from my Deck, Extra Deck, Field, and Graveyard for a unified summon!"

"Except for the Final Road to Ruin in the graveyard, the effect of the Star-Reading Magician is nullified."

"Damn it, a last-ditch effort. I'll cover one card. End of turn." Zack snorted and ended his turn.

Hope was rekindled in the hearts of the two Seele hanging in the sky.

"My turn—"

The top card in the deck lit up with a golden light.

"Draw a card!"

Xing glanced at the card he had drawn, a glint of light flashing in his eyes. In that case, there was a chance.

"Activate the banished zone's the Final Road to Ruin once per duel. Return this card from the banished zone to the deck and shuffle it. Then draw cards based on the damage you took in the previous turn. For every 1000 damage I took, I can draw one card. Since I took 2500 damage, I draw two more cards!"

The dazzling golden light shines once again on the deck.

"Put everything on this gacha pull, Shining Draw!"

With a roar, Xing suddenly pulled out two cards, which drew a perfect arc in the air.

"Activate Quick-Play Spell Card from my hand! Valkyrie Roll Call! When there are 6 or more Valkyrie monsters with different names in my Graveyard or Banished Zone, bounce all cards with the 'Valkyrie' tag on the field back to my hand!"

Xingchao Zack roared, "Give me back my Seele!"

Black Seele, hanging in the sky. "Who's yours? Seele is clearly mine!"

"Wishful thinking! I'll pay half my life points to activate Trap Card. Divine Warning: Your spell activation is nullified and destroyed." Zack looked at the battered and bruised Yuuki with a mocking expression. "Looks like all of this was in vain, Yae Xing. You have no future!"

"That's hard to say! (Sorewadokana?!)" Sachi sneered as she played the second card she had just drawn. "I activate a counter Trap Card from my hand, Awakened Wind of Desire. When I have no Valkyrie monsters on my field, this card can be activated from my hand to negate and destroy the activation of Divine Warning. Then, I negate the effect of Wendy Wind of Desire from my Graveyard and Special Summon it from my Graveyard with its Level, ATK, and DEF halved."

A green hurricane gathered before the knight, and the bandaged girl reappeared.

"Give Seele back, Zack, no, Sakaki Yuya!"

"Shut up! Don't mention that name in front of me!" Hearing this strange yet familiar name, Zack's face contorted even more, and the phantom of the Supreme King behind him gradually materialized. Taking advantage of his momentary lapse in concentration, the black and white twin girls, aided by Sachi's power, broke free from his control, and two orbs of light, one red and one blue, merged into Sachi's body.

"Welcome back, Seele." Sachi gently covered her chest, feeling the tremors of Seele's heart.

"Hello, thank you for saving us..." This was White Seele, who was shy.

"Hmph, since you saved us, I won't hold your earlier remarks against you." This was the irritable Black Seele.

Damn, I just said that because I was in a rush of anger. Won't my favorability towards them drop?

"It's not over yet. Lend me your power, Seele." Looking at the two extra pendulum cards in her hand, Sachi's previously flustered emotions somehow calmed down. Perhaps it was because with Seele around, she didn't have to worry about not being able to win?

"Okay, okay!"

"Yes, yes, yes!"

"I activate Spell Card from my hand: Valkyrie Revival! Return from the Graveyard, the Blade of the Thunder Queen!"

A bolt of lightning struck out of nowhere, and the vengeful warrior returned from hell.

"It's coming, Zack!" A raging flame burned on the Stigmata on his right hand, as if resonating with something.

(The following Yu-Gi-Oh!! text descriptions temporarily revert to the old generation)

"I use my Level 4 Synchro Tuner, Wendy Wind of Desire, to perform a Level 8 Synchro Tuning on my Level 8 Synchro Monster, Blade of the Thunder Queen! Accelerate Synchro!"

Fortunately, he was shouting almost at the top of his lungs to vent his excitement.

4★ + 8★ = 12★

"The bonds that connect us will illuminate the path to the future, becoming the flame that ignites tomorrow! Synchro Summon, undying legacy, the flame burns eternally!"

"Descend here!"

Kiana Kaslana!

The Law of Fire and Flame!

This was the second trump card that You Hui had given him.

The warrior's figure emerged from the raging flames. A girl dressed in white armor raised her greatsword and fearlessly pointed it at the demon from another world, her blue eyes filled with unwavering determination.

The four gemstones—red, blue, purple, and gold—reflect each other on the hilt, radiating a powerful aura.

"Damn you You Hui! No wonder you asked me for my card a few days ago, so that's what it was about. You were almost winning against Yue in the Yugi, Silly Loli You Hui..."

KK, who had been forcibly summoned, looked annoyed and muttered to himself in a voice only he could hear.

Ouch! Who's talking bad about me?

However, fighting against those who want to destroy beauty has always been her motto, so she'll just consider it working a little extra.

KK raised his Great Sword of Cinder, and Yuki also raised his Heavenly Fire Judgment: Oath of Protection.

"Xin Yan—"

"Heavenly Fire—"

"Draw your sword!"

"Draw!"

Two flaming blades were swung out simultaneously, striking the Odd-Eyes Pendulum Dragon and Zack one after the other. A massive amount of energy enveloped Zack's astonished face, and the figure of the Four Heavenly Dragons was also engulfed within it.

Zack LP: 4000→0

"Is it over?" White Seele asked expectantly.

"Of course it's not that simple. It's a BOSS after all." Xing stared intently at the smoke from the explosion, gripping his weapon tightly.

"Hey kid, take them and get out of here. The next battle is beyond your capabilities right now." Suddenly, KK turned around and said to Xing behind him, "Hurry up and go. I can't guarantee your safety while we're fighting him."

"Huh? You, you can talk?!" Xing was stunned. Come to think of it, something seemed different about the Flame of Knowledge that You Hui gave her. The hilt of the sword, which should have been the Herrscher Core of Knowledge, was replaced with a purple gem. And why was she wearing the Kalpas mask on her face?

"Why are you looking at me with such surprise? I'm not some card spirit. If it weren't for that bastard You Hui tricking me and giving you the medium to summon me, you wouldn't have met me so soon." KK rolled her eyes at him, then waved her hand, Herrscher of Flamescion synchronization card appeared in her hand. "To truly obtain this power, you and your companions need to work hard. I'll collect it now. Oh, and the Moon card... is that one-time use?"

"What are you daydreaming about? Hurry up and move, he's about to recover!" Seeing that Xing hadn't moved, KK urged impatiently. The portal opened behind Xing. "It's a bit deep here. I can only teleport you to a place in the Quantum Sea that's closer to the Intrinsic World. The rest is up to you."

After a moment's hesitation, she asked, "May I ask what your name is?"

"Name? Just call me KK."

"That sounds like my name..."

"I chose this pseudonym first! Okay, now get out of here!" The girl, unable to bear it any longer, kicked him into the portal.

Damn, was White Comet, who kicked me into the Honkai World, just a cameo role? (No, she wasn't.)

The boy who was thrust into the portal thought this to himself.

"Then, I wish you good luck in battle, Kiana."

The girl sighed helplessly and scratched her hair in frustration. "Honestly, it's been so long since anyone called me that. I almost forgot I even had that name." Hearing the roar of the giant beast behind her, her head ached even more.

"Shut up!" KK raised his weapon, flashed in front of the Four Heavenly Dragons, and slashed down with his sword...

——Divider—— (A heads-up: the following text features disorganized scene transitions)

The exhausted boy flew out of the portal, sliding a long way across the ground. The battle with Zack had drained not only his spirit but also his physical strength. Coupled with the damage caused by the Dark Duel, he was now in no better condition than when he came out of the simulation combat system last time.

"Hey, are you alright?" Black Seele, who was possessing him, sensed his abnormality.

"It's alright, Sakura, give me strength." Sachi called upon the Miko maiden and transformed into her purple adult form.

As for why he switched forms, it was because, within his field of vision, a dark Quantum Shadow was surging toward him.

Pulling the crimson Crimson Cherry Blossom from the Stigmata, Yuki slapped her head and charged forward.

"Get out of the way!" KK punched away one of the tentacles of the Voracious Poison Polymerization dragon, attaching flames to it.

"You wretched little brat, how dare you steal my things! Then you'll experience firsthand the consequences of going against me!" Zack's expression was incredibly exaggerated.

"They are not yours!" A surge of lightning spread from the girl, repelling the four dragons surrounding her.

"Ha!" With great effort, he swung his katana. His heavy body could no longer keep up with his brain. He put on the Build Driver to enhance his combat power.

Quantum walls appeared around him and then quickly surrounded him, seemingly trying to imprison him.

The next second, Build in his Scarlet Drill Form swung his big fist and walked out, knocking away a giant crab that was trying to crush him.

"Who else?!"

KK rode on the back of Odd-Eyes Pendulum Dragon, gripping its horns with both hands, trying to control it like Dragon Knight tamer, while three dragons she had knocked down lay beside her.

"It seems that the Four Heavenly Dragons in their normal state can't do anything to you, so—" Zack didn't seem flustered at all, a cold smile appearing on his lips.

"Evolve, my kin!"

He managed to block the massive fist in front of him, but he was still sent flying by a single slap from Tonatiu the Shadow of the Sun. "Damn it, I don't even know how many of these guys I've killed in the Memory Battlefield..."

The knight, sent flying, crashed heavily to the ground, deactivated his transformation, and struggled to stand up. However, his body, already at its limit, could no longer keep up with his will. The Quantum Shadow he had brutally beaten swarmed around him, overwhelming his vision.

The Desire Poison Polymerization Dragon unleashed a fierce beam of light, the Crystal Wing Synchro Dragon flapped its bright wings, the Odd-Eyes Rebellion Dragon unleashed its firepower, and the Odd-Eyes Advance Dragon flapped its newly grown wings, launching attacks on KK from four directions. Brilliant fireworks covered the girl's figure.

"It's not over yet!"

The Quantum Shadow piled up on Sachi's body were swatted away by the possessed Black Seele with a claw. Sachi, with bloodshot eyes, swung the scythe in his hand and cut all the Quantum Shadow that approached him into pieces.

"Hey, wait a minute, Black Seele! We're running low on energy, don't use such energy-consuming fighting methods!"

"Then what do you suggest we do? Hey, when did it become 'we'? Seele and I are only temporarily attached to you right now. Once you're out of danger, I'll take her away immediately!"

Hmm, she's a Tsundere ~

"I have a plan, Black Seele, White Seele, do you believe me?"

"Huh? What do you mean? If I didn't trust you, would I have followed you all this way?"

"Is White Seele talking about me? Seele isn't a goat... But Seele is willing to believe this stranger!"

"Spirit Flame—Draw your sword!"

The instant the attacks of the Four Heavenly Dragons struck, KK used the power of the Herrscher of Void to teleport above them, leaving four portals that redirected their attacks towards each other.

"Interesting, truly interesting, I can't help but want to destroy you!" Zack held up the card of the Star-Reading Magician and slowly read aloud:

"Now, let's become one!"

The light of black and white shone on the boy, like a flower bud about to bloom.

"I'm setting Seele Black Abyss and Seele Abyss Flower to the Pendulum Scale! Pendulum Summon!"

Two phantoms of Seele appeared behind him, each extending a hand and placing it on the red mark on his chest.

"Resilient and powerful twin flowers, grant me once again the strength to overcome all. Reign supreme, Knight of Stillness of the other shore!"

Bonded Weaponry: Sea of Butterflies

Fortunately, she regressed into a red-eyed power type, the inside of her hair turned blue, her clothes changed into a formal dress, and her eyes slowly opened, revealing a clear blue like the ocean.

Faced with the overwhelming Quantum Shadow, he waved the Door of the Other Shore in his hand, moving freely within it like a dancing butterfly, leaving behind only a pile of Quantum Shadow without even a trace (indeed, after defeating it, there was nothing left).

Faced with the onrushing Tonatiu, the boy's lips curled into a terrifying smile, and his eyes and the inside of his hair turned a blood-red color.

Come play with me!

The scythe disappeared, replaced by two huge red claws, and the dress on his body also changed to a red and black color scheme.

KK scratched her hair in frustration. The enormous Supreme King Zack stood before her, its eerie green eyes staring at her, sending chills down her spine.

"Don't look at me with such disgusting eyes!" Unable to bear it any longer, the girl swung her sword, but the flames she unleashed were like tiny sparks in front of the giant beast, unable to cause any damage.

"Hmph, so hate your powerlessness and meet your Finality in regret! Let me bestow upon you the reward called [Despair]!" Zack, now one with the Four Heavenly Dragons, launched an attack on KK. An unprecedentedly thick beam of light erupted from the Supreme King Zack's body, striking KK as fast as lightning.

"Oh no, it seems like I can't dodge this. It's an attack of this magnitude that I can't seem to transfer. Well, I guess I'll just have to bite the bullet and go for it!" KK gripped the Great Sword of Cinder in its unfolded mode and charged forward fearlessly.

"However, the Finality and despair are nothing new to me!"

The girl's tiny body stood in front of the enormous breath, looking as if she might be swallowed up at any moment.

"Give up the fight! You can't defeat me!" Zack arrogantly raised his head, seemingly already foreseeing KK's demise under this attack.

"You bastard, just a mere clone—" The girl's eyes gleamed, and her energy surged several levels in an instant.

Don't underestimate me!

A pair of wings made of flames bloomed behind the girl, propelling her to fly further and further away.

However, the enemy was simply too powerful.

"Ugh, I'm being pushed back..." Cold sweat beaded on the girl's forehead, instantly evaporating in the nearby heat. "Damn it, how can it end like this?!"

Yes, we can't let it end like this.

A fair, delicate hand was placed on her hands, which were tightly gripping the sword hilt. KK was stunned and turned her head in disbelief. The blonde girl smiled knowingly at her, and a familiar power flowed into her body.

"I knew it, you bastard, you've been watching this place all along..."

The two suddenly exerted their strength, slashing the swords forged from their bond towards the enormous beast.

On the other side, Tonatiu, who had been swaggering around, was turned into a lobster by Sachi using the Black Seele Armor. Sachi looked at the empty surroundings, silently breathed a sigh of relief, and collapsed to the ground.

"I'm too weak to go on..."

In a daze, he saw a blue, Ghostfire Motorcycle speeding towards him...
