"Come, show me, human from another dimension, your duel."
It can talk?
Tenjo Hikari raised an eyebrow.
"My turn, draw."
The opponent kindly didn't insist on the riding duel popular in this world and opted for a regular duel.
Though it was unclear what kind of opponent it was, making it impossible to conduct his favorite "information duel," Tenjo Hikari didn't particularly mind this aspect.
He carefully looked at his hand cards and revealed one: "I activate the Field Spell, Fusion Recycling Plant."
The clinking sound reverberated on the field as numerous drones flew around, getting to work.
"Activate the effect of the Fusion Recycling Plant, discard a card in hand to activate it. From the deck or graveyard, add a [Polymerization] to the hand card.
I add the Spell Card [Fusion Substitute] from the deck to the hand cards."
Tenjo Hikari added Polymerization from the deck to his hand and then revealed another card: "Normal Summon, Elemental Hero Prisma."
A crystal warrior, seemingly with two wings, composed entirely of crystals, appeared on Tenjo Hikari's field.
"Once per turn, show a Fusion Monster from the Extra Deck to the opponent; send one Fusion Material Monster listed on that monster's card from the Deck to the Graveyard.
Until the end of the turn, this monster's card name is treated as the same name as that card.
I reveal Thunder Dragon Colossus from the Extra Deck, and send a Thunder Dragon from the deck to the graveyard."
"Oh? Universal Fusion Material, as fusion material, it is indeed very powerful," Skull Knight commented briefly as he watched the card take effect, "Human from another dimension, continue your duel."
He appeared quite at ease, seemingly very confident.
Tenjo Hikari frowned, still unable to grasp his situation, but it didn't matter at this moment.
"Activate Spell Card, Thunder Dragon Fusion!"
He turned over another card and showed it to the opponent.
"This card can return monsters from the field, graveyard, and banished state to the deck to Fusion Summon a Thunder-Type Fusion Monster!"
Tenjo Hikari squinted his eyes, raised his hand, and clenched it fiercely, as if gripping a ball of lightning: "Step into a new realm of fusion — Fusion Summon!
Thunder Dragon Colossus!"
Boom!
A bolt of lightning struck from the sky, and a shadowy dragon slowly emerged from the mist, revealing its true form.
Thunder Dragon Colossus, LV 8, Dark Attribute, Thunder-Type, ATK 2600.
"Oh-ho, quite an imposing monster." Skull Knight remained exceedingly confident, seeming entirely unperturbed.
"You seem quite confident." Tenjo Hikari raised an eyebrow, seeing his confidence, seemingly unafraid of Thunder Dragon Colossus, he couldn't help but speak, "I just don't know if your confidence is self-assurance or arrogance like those nobles."
"Activate the effect of Metalfoes Fusion discarded in the graveyard, shuffle this card into the deck. Then, draw a card."
Tenjo Hikari drew a card, looked at Skull Knight, and set it on the field.
"Set one card, end turn."
"Hehehe..." Skull Knight chuckled softly, as he laughed, even faint blue ghostly flames appeared at his mouth.
"My turn, draw a card—"
As he spoke, in Tenjo Hikari's eyes, his body suddenly grew larger, with his skull face appearing directly in front of Tenjo Hikari as if about to swallow him whole.
Tenjo Hikari frowned, bending his body slightly, the power of darkness, the breath of death, made him feel an unfounded sense of "fear". Although this feeling of fear came and went quickly, Tenjo Hikari still realized the extraordinary nature of his opponent.
On the other hand, Tierra suddenly clapped her hands together, summoning Infernoid Pirmais.
The appearance of the Archfiend added a layer of protection to Tenjo Hikari, and the eerie flames burning on this dark Archfiend dispelled much of the aura of death and decay around.
Skull Knight opened his mouth, making a "cackle" sound— Heavens above, Tenjo Hikari heard such a bizarre laugh in reality for the first time.
"Indeed, my observations over the past few days were not wrong."
Tenjo Hikari confirmed his previous speculation upon hearing this.
This guy had indeed been secretly observing him for a long time, and today he took advantage of him being alone to attack him!
"The dark power you wield is more formidable than I imagined, it may not be the ultimate darkness, but this evil indeed meets my requirements..." Skull Knight laughed eerily, his jaw making a creaking sound, making Tenjo Hikari almost think he might laugh his jaw off physically.
However—
Evil power?
He glanced at Tierra, who shrugged and indicated she had nothing to say.
Although she didn't personally distinguish between "justice" and "evil" in her beliefs, her actions in her world were purely out of her divine office, but in human perception, her power, her creations, were indeed "evil."
Just like when Akaba Leo possessed Kambayashi Kaname, feeling her filled with evil, now adding the genuine devil "Satan" makes it quite normal to be seen as an antagonist.
Clearly, Skull Knight also regarded him as another dimension person possessing and using dark powers.
Moreover, the opponent came for this reason.
"My turn, human, let me show you the [Fusion] belonging to the dead."
!?
What's that?
Tenjo Hikari thought he heard it wrong.
In the S Dimension, in this world which is likely a blend of "Yu-Gi-Oh! 5D's" and "Yu-Gi-Oh! A5", a world principally revolving around "Synchro," using "Fusion"?
He was stunned for a moment, and the opponent had already started their operation.
"When there are monsters on the opponent's field and no monsters on your own field, this card can be Special Summoned!"
"Come forth, my soldier!"
"Special Summon, Ghost Lancer, the Underworld Spearman!"
A skeletal warrior spinning a long spear leaped onto the field.
Ghost Lancer, the Underworld Spearman, LV 5, Dark Attribute, Zombie-Type, ATK 2000.
Ghost...?
Huh?
Tenjo Hikari finally realized who the opponent was.
The person using this deck, there was only one possibility— Rudger Goodwin!
Rex Goodwin's elder brother!
So it's really "Skull Knight", not a Spirit!
But!
How is this possible?
His mind was a bit boggled for a moment.
These days, through exchanges with Yusei, Yugo, they found the world was the animated world of "Yu-Gi-Oh! 5D's", so why would a manga character appear— but he quickly accepted this fact.
Nothing to be surprised really.
This world's Manjome is still Kaiba's disciple.
"Next, Spell Card— Ghost Fusion!"
He tossed a Spell Card featuring a rotating skeleton and dragon on the card image.
Seeing this card, Tenjo Hikari was even more shocked.
"This card allows for the fusion of monsters on the field with Zombie-Type monsters from the graveyard or deck — "
Gosh, it's the original Ghost Fusion!
Tenjo Hikari was thrilled seeing this Ghost Fusion — in physical card form, the Ghost Fusion – Ghostly Fusion requires lower Life Points than the opponent to use deck monsters as Fusion Material!
His heart for collecting Full Fusion was ignited instantly.
"I fuse the Spearman on the field with the Ghost Wyvern from the deck!"
The skeleton on the field and the Dragon of Death from the deck turned into bones, flying into the sky.
"Using the souls of two deceased, summon the Netherworld Dragon!"
With his shout, the previously calm sky suddenly appeared shattered like glass, forming many cracks, a giant dragon with a skull face ceaselessly clawing at this shattered world.
"Break open the gate of the Netherworld!"
The Netherworld Dragon slammed its head into the world, shattering it and creating a massive Black Hole.
Tenjo Hikari felt slightly breathless, causing Tierra to frown and raise her hand, manipulating countless puppet strings to enhance Satan's size, making Tenjo Hikari feel less uncomfortable.
"Ghost Fusion!
Dragonecro Nethersoul Dragon!"
