I'm in Yu-Gi-Oh!, but I'm also in Machine Ascension.

"I accept your kindness, Senior Youfeng. If you make the first move, I'll take it down!"

...

At that moment, after both of them were certain that Manjoume Jun would have the first move in this duel, they reorganized their hand resources and, after a brief review, played a [Field Spell] card as their starting card:

"So, at the start of my turn, I'll play a Field Spell card first—[Union Hangar]!"

In an instant, as the card entered the Duel Disk's exclusive [Field Spell] area, the area where the two were located was also instantly transformed. Behind the black-haired boy, Manjou, a box clearly marked with the letters "VWXYZ" immediately appeared, seemingly hiding a card of some powerful monster.

"This is?!"

Soon, upon seeing the scene unfolding behind Manjoume, Marufuji Ryo, who was watching the battle, was momentarily stunned:

"This... doesn't seem to belong to Manjoume's previous deck... Is it a new deck?"

Just as a hint of surprise and astonishment flashed in the blue-haired boy's eyes, at this very moment, as the duel was about to begin, a series of disappointed voices filled the large classroom. A boy with a "jellyfish head" hairstyle, along with the long-haired yellow-haired Tenjouin Asuka, returned to the classroom with regretful expressions.

"Seriously... what is this... I rushed over immediately... and it's still completely sold out..."

"We came up empty-handed!"

...

As Jaden Yuki, sporting the "jellyfish head" hairstyle, complained about the business, the girl beside him, also slightly tossed her hair and sighed in disappointment:

"Indeed... I originally wanted to see if there were any upgrades for [Xyz] or [Ritual] in this new deck..."

"I wonder who has such a big budget... to actually buy out all the card packs in one go, it's truly amazing!"

Amidst the girl's equally dissatisfied voice, the "jellyfish-headed" boy beside her, Yuuki Jaden, nodded in agreement, his gaze immediately sweeping towards where Yuuki had been standing:

"Originally, I was going to...as an apology to my seniors...give them a card holder..."

But the next second, when they realized that You Feng was not in the same place and his gaze was blankly spreading across the podium, everyone instantly realized that something was wrong with the atmosphere at this moment.

"Hmm... A new duel?! This time the opponent is... Manjoume-kun?!"

...

Soon, amidst the astonished gazes of the crowd, Wan Zhangmu Jun glanced sideways, a satisfied smile appearing on his lips:

"Hmph~ Looks like there are plenty of witnesses!"

Soon, the boy wearing the Obelisk-Blue academy uniform pointed his finger at the [Field Spell] card that had just been played and activated on the field—

"As part of the effect of activating this card, you can add 1 Machine-Type + LORD Union Monster from your Deck to your hand."

Then, amidst the astonished gazes of the crowd, Jun Banjou immediately removed his entire deck of main monster cards from his Duel Disk. After briefly reviewing the restrictions, he swiftly and easily selected a corresponding lower-level monster card.

After successfully acquiring it, Jun Manjoume didn't stop there, immediately launching it into the main monster zone in the front row:

"Then I will immediately summon a 4-star [A-Assault Core] in face-up attack mode!"

"Come forth! Allied Monster [A-Assault Core]!"

In an instant, accompanied by a flash of yellow light, a massive tank, employing laser cannons as its primary means of attack, roared in:

【A-Assault Core】

[Star rating: 4]

[Attribute: light]

[Race: Mechanical]

[Attack power: 1900]

[Defense: 200]

...

"Wait... [A-Assault Core]?!"

"Is it a completely new deck?! Could it be...?"

Soon, upon seeing the gleaming new monster card played by Jun Manjoume, Jaden Yuki's expression instantly changed, showing a hint of surprise:

"How did this kid even fly to the card shop to buy cards?!"

"However... after all, money is power..."

At that very instant, as the boy with the "jellyfish head" Yuuki Yuki sighed slightly, the girl Asuka Tenjouin also frowned, as if realizing something:

"These monster cards... why do I feel a vague sense of familiarity about them..."

Soon, as she gazed at the unusual, heavily armored chariot once more, a flicker of realization flashed across the girl's brown eyes:

"Could it be..."

...

Meanwhile, Kaiser Akira, who was the first to notice Manjoume's new deck, immediately realized what was happening:

"It's...that kind of [Fusion] deck with a unique and highly customizable nature...the [VWXYZ] deck held by the legendary duelist Seto Kaiba..."

Soon, with Marufuji Ryo's expression unchanged, and because reading the classic deck of the legendary duelists and revealing it was a required course for everyone in this Yu-Gi-Oh! GX timeline, almost instantly, the spectators also understood what this deck meant.

...

"Well... although it's a bit unexpected, the deck that's supposed to drop rare cards actually dropped a legendary deck... this really is a stroke of luck!"

Soon, Professor Chronos, the golden-haired mushroom-headed man who had been hiding in the shadows of the crowd, thoroughly enjoying the astonished atmosphere, also let out a delighted laugh:

"...It contains the power of that legendary duelist, President Kaiba. Even Director Yuuka would be able to defeat it!"

...

At that very moment, just as everyone was astonished by this set of cards, which was related to the legendary deck [VWXYZ] held by Seto Kaiba, one of the world's top three legendary duelists.

Just as Seto Kaiba was "monitoring" Yuuki through the Duel Academy's surveillance system within the Kaiba Corporation, a satisfied smile instantly appeared on his lips:

"Although the process was a bit convoluted... it seems... the right person has gotten this deck..."

"Yufeng...although we're not planning to meet him yet...this deck possesses formidable power..."

"Even when facing Yuuka, who has unlocked the power of [Xyz], you still have a strong ability to restrain him."

Soon, in the deep, commanding voice of Seto Kaiba, a man in a stylish white trench coat, his piercing gaze immediately fixed on the handsome face of the long-lost boy, Yuuka, in the camera lens.

...

Meanwhile, after playing the signature low-level monster card from the [VWXYZ Deck], Jun Manjoume arrogantly raised his head, quite satisfied with the reactions of those around him. After a smile, he pointed to the [Field Spell] card that was the starting combo in this duel:

"Following my recent normal summoning of the [A-Assault Core], now, according to the effect of this [Alliance Hangar]—"

"Once per turn, if you Normal/Special Summon a Machine-Type + LIGHT Union Monster on your field, you can target that monster and select 1 Machine-Type + LIGHT Union Monster from your Deck with a different name that can be equipped to that monster, and equip it to that monster. The Union Monster equipped by this effect cannot be Special Summoned this turn."

"Therefore, I will now conduct another search, and this time—"

Soon, after opening his main deck again, Jun Manjoume, almost without thinking, as if he had prepared in advance, under everyone's watchful eyes, directly drew a Level 4 LIGHT Machine-Type Union Monster that matched the style of the [A-Assault Core] in the front row.

This time, however, it was applied directly as a sticker in the magic trap area in the backcourt:

"Then, I will immediately equip this [B-Destroyer Dragon] as an [Equip Spell] card to [A-Assault Core] on the field!"

This time, with Wan Zhangmu's increasingly powerful aura, the mechanical dragon monster with its wings spread out like a Tyrannosaurus Rex carrying a heavy cannon was instantly blasted into the magic trap area behind it.

Soon after, Jun Manjou also played his second [Spell] card from his hand!

"Don't be surprised... I'm going to activate another [Continuous Spell] card from my hand—[Frontline Base]!"

In an instant, a scene depicting a knight riding a black dragon flashed behind Jun Manjoume, within the original Allied Hangar that had been built behind him, a scene that concealed even more Allied monsters.

"The effect of this card is very simple - once per turn, during your Main Phase, you can Special Summon 1 Level 4 or lower Union Monster from your hand!"

...

"So, is Manjoume going to play his third [Union Monster] on the field now?"

In an instant, with the flash of this [Continuous Spell], everyone, who knew the powerful force that the [VWXYZ Deck] in the hands of former president Seto Kaiba could generate, also watched the situation on the field with very serious expressions.

Then, Wan Zhangmu Jun also smiled mysteriously, a smug look on his face:

"...That's right, I'm immediately Special Summoning a Union Monster from my hand in face-up Defense Position—[C-Crushing Wyvern]!"

As Jun Manjoume responded to the effect of the [Continuous Spell] card on the field—[Frontline Base]—he was immediately able to play a Level 4 LIGHT + Machine monster from his hand:

【C-Crushing Pterodactyl】

[Star rating: 4]

[Attribute: light]

[Race: Mechanical]

[Attack power: 1200]

[Defense: 2000]

In a series of maneuvers, three monsters from the same [VWXYZ Deck] were consecutively summoned to the field during the first turn's first phase using different methods from the deck and hand: face-up attack, [Equip Spell], and face-up defense.

Manjou-no-Machi also took a deep breath, his expression a mixture of excitement and nervousness.

"Hmm... to be honest, when I first received this new deck from Professor Chronos, I was quite nervous about whether I could thoroughly understand it in a short time to counter you..."

At that very moment, Professor Chronos, who had been secretly watching the fight from the sidelines, was also instantly targeted. Facing the gazes of everyone and those who had already noticed him, he immediately pretended to have just arrived and stepped out of the shadows, his scalp tingling.

"Haha... What a coincidence! Are you playing cards with Manjoume, Director Yufeng...?"

Youfeng: ...

Although accompanied by Jun Manjoume's seemingly deliberate, cryptic voice, almost everyone instantly understood that the "mastermind" behind Jun Manjoume was Professor Chronos, who seemed to have been defeated by Yuuki and harbored resentment towards his new love.

However, since the teacher was only giving the students a deck of cards, no one could say anything about it.

...

At that very moment, the black-haired boy in the blue uniform and trench coat, who was currently executing his combo, suddenly became confident and determined to win. His eyes flashed as he pointed his finger at the three Machine-Type [Union] monster cards on his field:

"But... the moment I saw this VWXYZ deck from the [President], I immediately felt victory was within my grasp!"

"This [VWXYZ] deck doesn't require [Fusion] spell cards; it only needs specific materials to perform a feature called [Flexible Fusion]—"

"I banish three monster cards from the field: [A-Assault Core], [B-Destroyer Dragon], and [C-Crusher Wyvern]!"

"Come out!"
