Amidst the stars, the spaceship slowly docked, observing here.
This dimension is a training ground, strictly isolated from other dimensions. Normally, a human cannot find this dimension—after all, it requires the coordinates of the northern star from both human worlds to locate it.
Although the powers here are relatively harmonious with each other, they are still forces preparing for war, naturally disinclined to be disturbed by other entities, so this lockdown was specifically created by the "Great Leader" at their request.
The level of secrecy here is extremely high!
Therefore, whether it was the previous group or the latter group, they are actually quite dangerous here.
The former suddenly appeared in this dimension, rampaged across the battlefield, as conspicuous as can be, yet without being affected in the slightest, nor did they make any contact with them.
The latter appeared blatantly, without evasion, challenging the entire channel directly—
When the latter group spoke up, specifically naming "Drytron," it startled Drytron's leader, thinking they had encountered an enemy.
Thankfully, it was confirmed the visitors were either accidental or human warriors challenging, which made them slightly relieved.
But even so, coming to such a place to "challenge" is rather exaggerated.
Regardless, they still selected two opponents based on the duelist's "level."
They are curious about what kind of duel these two strange sides will have.
"You start first, Yuma-kun." Although Tsukumo Yuma is much younger than Marufuji Shou, his height is shorter by 8 cm, so they barely can look each other in the eye equally.
As an experienced duelist, Marufuji Shou was somewhat concerned about this child's first "duel trial" in the Spirit World and comforted him, "Don't worry, dueling with spirits isn't much different from dueling with humans."
"Oh! I understand!" Tsukumo Yuma smiled brightly, "I've dueled with the Fusion Army before and seen the spirits!"
"Fusion—Fusion Army—" Marufuji Shou's face slightly twitched.
A person who has battled the Fusion Army?
"My turn! Flying high, I am!" Yuma cared not for the surroundings, and with a great leap, summoned a monster midair, "Normal Summon, Goblindbergh!"
"When this card is summoned, you can special summon 1 monster from your hand with LV 4 or lower!"
"Special Summon, I, I, I Magician!"
A goblin riding a red plane flew above, pulling along a silent masked magician.
"Then—use Goblindbergh and I, I, I Magician to build the Xyz Network!"
A huge, dark vortex appeared before him. Marufuji Shou watched this scene, involuntarily side-eyed.
The two monsters silently transformed into golden light, swept into the dark vortex, and after a whirl, a massive, seemingly cylindrical mechanical "longsword" slowly emerged, and after spinning, unfurled mechanical wings, becoming a mighty warrior!
"Number 39: Utopia!"
Number 39: Utopia, Rank 4, Light Attribute, Warrior-Type, Attack Power 2500, Xyz Material 2.
"Number!" Marufuji Shou's expression instantly changed, "You're actually a Number user—and you seem pretty normal?"
Marufuji Shou had seen Number Monster users before, and the way they were consumed by desire was etched into his mind. More importantly, he learned that his brother mastered Xyz Summon because his life was threatened while dueling a Number Monster, forcing him to unleash his potential.
Seeing another Number user now, he naturally worried.
Yet unexpectedly, Tsukumo Yuma seemed perfectly fine.
"Ah—he's Hope, my partner!" Yuma explained openly to Marufuji Shou.
"But he's right. Most No. users do get lured by Number Cards—" Astral, floating beside Yuma, nodded affirmatively, "Yet now half of the Number Cards have been reclaimed by me, so they shouldn't go terribly wrong."
Half?!
Marufuji Shou and Tenjouin Fubuki were both astonished, looking at the radiant spirit, finding his claim absurd.
Half the Number Cards!
The energy of one Number Card already feels incredible, and countless duelists covet a Number Card to wildly increase their Duel Energy, and this person owns half the Number Cards?
Of course, this isn't the important part. What's crucial is—
Marufuji Ryo also holds several Number Cards in his hand!
"Have you seen my brother?" Marufuji Shou asked eagerly.
His brother's Number Cards wouldn't disappear into thin air. If this person truly owns half the Number Cards, he might've met his brother!
"Eh, brother—could it be Marufuji…" Mizuki Kotori sensed something unusual.
Could it be not just coincidentally named Marufuji Shou, but actually Marufuji Ryo's brother, that cool big brother?
"Eh? Could it be, are you humans from the Fusion Dimension?" Tsukumo Yuma realized belatedly.
Marufuji Shou remained silent, unsure whether he should respond at that moment.
