Mina didn't know what considerations led the master to formulate such a strange plan, the "Underworld Plan."
Simply put, it's a plan to gather duelists whom Yugen has fought or examined at Duel Academy, those he believes have strength or special talents, and form an elite team from Duel Academy.
Each duelist will begin testing and practicing based on the card deck they originally used, with a specialized team from Yugen's laboratory conducting tests to see their performance when using different card decks, testing their compatibility with the decks.
During duels, each member will switch between different card decks, trying various tactics. Ultimately, their personal preferences will be considered to determine the card deck and tactics that best match their personal style.
Only those with exceptional strength and consistent performance will be left to join this team.
In fact, this is something Yugen had considered for a long time. Because based on his memory of the original plot of "Yu-Gi-Oh! GX," he knew that relying solely on himself was not feasible.
In the early stages up until the Phantom Demon Chapter, it didn't matter, since the Seven-Star is said to be a dark group, but when it comes to attacks, it's essentially like the calabash brothers saving their grandfather, coming one by one. As long as your strength is strong enough to take them down one by one, there are no issues.
But starting from the Light Association Chapter and into the later Otherworldly Dimension Chapter and Darkness Chapter, personal strength is indeed the most important foundation, but having teammates who can fight would make many things much simpler.
There needs to be both a Grand General and an elite force.
Actually, Yugen always felt that Duel Academy should have elites. The episodic stories of the first season might feel ordinary and bland, but they actually showcased that Duel Academy is full of hidden talents. For example, a folk expert like Taira Oyama, whose strength is actually not weak.
In fact, he even made a brief appearance during the Light Association Chapter. During the GX tournament, when Academy students faced continuous defeats and low morale against professional players, a few exceptionally talented elite students stepped forward and even defeated top-ranked professionals, including this Oyama.
So Yugen thought, the academy can have a strong team. Whether facing the Light Association now, or in case they are trapped in the Other Dimension in the future, this team will be a critical force.
The GX tournament is the best stage to test this team, and the Light Association invaders are the most suitable opponents for real combat.
Because unlike most of the students' usual duels, dueling against these invaders is real combat and closest to the pressure of a Dark Duel, which is different from regular duels.
However, although it's called a Dark Duel, it's not truly that dark, because even if they lose, they will only be brainwashed by the Association and not actually perish. So, although it's a bit troublesome, being brainwashed can actually be reversed, and the risk is acceptable.
At least it's better than directly sending them to gamble their lives in a real duel.
And the team's performance on the first day didn't disappoint. All dispatched members won, without anyone slipping up.
Only looking at the side of the Light Association, they might have a sleepless night wondering if they invaded Duel Academy or the Underworld...
The students on the academy's side can fully control the situation, which made Yugen relieved after observing for a day.
Even if some unexpected situations arise, Duel Academy's elite team still has Yuki Judai as the ace. Now that Judai has obtained Ultraman's power and acquired Dark Fluctuation, his strength has greatly improved and is enough to hold his ground. With him around, most unexpected situations don't need to be worried about.
Yugen can also proceed to deal with other matters.
For example, the world champion named D.D. he previously had people keep an eye on, seems to have once again stepped onto the world stage, about to enter this year's Professional Alliance World Championship stage.
Yugen only remembered the tournament because someone mentioned it.
Although he sees the professional league as childish games, it's still generally recognized in this world's dueling realm.
The recent professional league is also reaching its climax, with the championship showdown approaching, attracting a lot of attention from surrounding people.
Yugen remembered if he was not mistaken, some unexpected event was supposed to occur in this tournament.
...
...
In a certain place, a dark room.
"Arrrgh!"
The man let out a beast-like roar.
The room had no lights on, engulfed in darkness. But inside, the furniture and items were a mess, the coffee table was overturned, cups and plates shattered on the floor. The wardrobe was overturned too, with clothes scattered, and scattered cards everywhere.
This crazed man is D.D., once at the pinnacle of the professional circle, holding the championship title.
For many years, he maintained a perfect image. He was a suave and gentle person, always keeping a gentlemanly facade. He was also an excellent guardian, the guardian of the professional league's superstar newcomer, Ed Phoenix, and had always been portrayed by the media as a good father.
But no one knew his true appearance, not even Ed whom he was the guardian of. No one knew the torment he endured day after day over the years.
He was now desperately pressing his left hand against his right hand, showing signs of his Qilin arm losing control. That restless right hand seemed to be moving uncontrollably, stretching towards a briefcase amidst the mess.
"No, I can't…"
D.D. was still trying to control his about-to-loss-of-control arm.
"This card, only this card, absolutely cannot…"
"What can't be done?"
In the broken mirror beside him, his reflection grinned at him. Although it was a reflection, it looked completely different from him at the moment.
He was pressing down his arm, struggling desperately, his expression twisted with clenched teeth. But the figure in the mirror was smiling lightly, like a demon enticing someone to sign a contract.
"It doesn't matter anymore," the reflection said, "The light is about to descend, it's the End Light that will flatten everything in the world, turning it into a pure white void.
By then, all cover-ups, all sins, will be meaningless.
You've controlled it long enough."
As the demon spoke its words, the man's vicious expression gradually relaxed, his gaze slowly merging with that of the reflection.
"Indeed, it's been long enough. The world is going to end, there's no need for concealment anymore..."
He said, finally releasing his left hand, allowing his right hand to act freely. The unleashed Qilin arm delivered a single punch, its exaggerated power forcibly shattering the briefcase.
He opened the case and took out a card.
A card emitting a dark, ominous aura.
"Ten years, finally..."
The corner of the man's mouth lifted, revealing a devilish smile.
"Ultimate D, give me the rest of your power... I'll take it all."
