The fusion spiral representing D/D/D erupted within the imperial cathedral.
Everyone who witnessed the scene with their own eyes stood dumbfounded, utterly at a loss for how to react.
Condensing such an immense demonic power within a sacred cathedral was, in itself, already absurd beyond belief.
"By the effect of [D/D Swirl Slime], fuse this card with [D/D/D Dragon King Pendragon]! The mysterious spiral that freely shifts form, envelop the ever-victorious Dragon King and let it be reborn as a true God King!—D/D/D Oracle King d'Arc!"
[D/D/D Oracle King d'Arc] Level 7│DARK│Fiend│2800 ATK│2000 DEF
["D/D" monsters ×2]
Named after the savior saint Jeanne d'Arc, the Fusion Summoned d'Arc spread the twin wings of a demon god king, holy sword in hand, as she descended into the center of the cathedral.
Making a corrupted Saint Jeanne d'Arc manifest and fight on the turf of a sacred cathedral—only D/D/D could pull something like that off.
"So I wasn't mistaken after all!"
Seeing the demon gate opened and the D/D/D monsters of the other-dimensional demon kings appear, Sylvia's suspicions were fully confirmed.
This boy's soul had definitely been tainted by demons, and she would have to be the one to purify him.
Purify him through a duel before the gods!
And if the purification wasn't complete… then perhaps purify him by other means at night~?
"O gods, please grant me the courage to stand against defilement!"
With this final devout prayer, Sylvia was keenly aware that after opening the demon gate, Miles now had only one card left in hand—this would be the decisive turn.
As long as she could endure it, she could seize victory in this duel.
"2800 Attack on [D/D/D Oracle King d'Arc], huh?" Irena frowned in thought. "That's… a bit subtle."
During academy duels, the first Fusion Summon of D/D/D had once stunned the entire field, and with the support of the Contract, d'Arc had thoroughly suppressed the combined Magnet Warrior god.
Albeit that duel had ultimately just been Miles bullying first-year rookies with an incomplete deck.
That's right. Although the current D/D/D monsters were being personally summoned by Miles, there was no doubt that this was still an incomplete deck.
Blindly using the power of a half-finished deck to challenge a terrifying battlefield like that of the imperial nun Sylvia was, by Irena's experience, an extremely risky move.
The sheer gap in raw Attack alone was already difficult to overcome.
"The path of evolution is forged in battle! There's nothing more suited to a deck's growth than real combat!"
From the very beginning, Miles had always fought like this.
So what if the deck was unfinished? Back then, when he wielded Aisha's ragtag deck that barely even had Spell and Trap Cards, Miles had still completed its evolution step by step through battle.
Now, he was simply walking that same road once more.
And this time, Miles was no longer fighting alone.
Behind him, within the Millennium Puzzle's Soul Room, countless doors representing different decks lent their strength together to a new stage of evolution—proof of all the battles he had fought before.
"Continuous Spell Card, activate!" Placing his final card onto the field, Miles activated his second Contract.
"—I activate [Dark Contract with the Swamp King]!"
[During your Main Phase: You can Fusion Summon 1 Fiend-Type Fusion Monster from your Extra Deck, using monsters from your hand or field as Fusion Materials.
You can only use this effect of "Dark Contract with the Swamp King" once per turn.
If Summoning a "D/D" Fusion Monster this way, you can also banish monsters from your Graveyard as Fusion Material.]
A Contract card that could replace a Fusion Spell—and when Fusion Summoning a D/D Fusion Monster, it could banish materials from the Graveyard directly, just like Miracle Fusion.
"Use this fusion to construct the deck's evolution! I fuse the [D/D/D Oracle King d'Arc] on my field with the [D/D/D Dragon King Pendragon] in my Graveyard!"
This wasn't a fusion using D/D Slimes. This Contract Fusion directly funded the strongest combat power currently available to D/D/D.
It was the strongest possible fusion using two D/D/D monsters.
Sylvia cried out in shock, "After fusing once, you're fusing again… using a Fusion Monster as material?!"
"Break through the desperate dead end of Malefic World! With surging, raging waves, open up a brand-new world! Fusion Summon! The ultimate tyrant god!—D/D/D Wave Oblivion King Caesar Ragnarok!"
[D/D/D Wave Oblivion King Caesar Ragnarok] Level 10│DARK│Fiend│3200 ATK│3000 DEF
["D/D/D" monsters ×2]
The Fusion Material requirement was no longer two D/D monsters like with d'Arc, but two higher-grade D/D/D monsters.
Caesar Ragnarok did not refer to the royal Kaiser of Livorden on the Spirit Continent.
Rather, the heroic spirit that served as this card's prototype was Julius Caesar of the Roman Empire—Gaius Julius Caesar, whose name resounded across the world.
Clad in heavy black armor, Miles' brand-new, full-power D/D/D Fusion Monster descended in the name of Caesar, holding down all three of the monsters on Sylvia's field.
"How is this possible?!" Sylvia's legs couldn't help but tremble. "It's just a Fusion Monster with 3200 Attack… so why… does it feel this terrifying?"
Ominous, imposing, and awe-inspiring without anger, [D/D/D Wave Oblivion King Caesar Ragnarok] stood on Miles' field like a reborn other-dimensional demon king, openly challenging the authority of the gods within the cathedral.
"I won't lose!" Sylvia retorted forcefully, the dignity of a clergy member driving her voice.
"How could I be defeated by something like a demon? Whether it's Attack or Defense, the monsters on my field are superior."
"That's true. Your monsters do have higher Attack," Miles replied. "But what I want… is exactly that higher Attack!"
With the fusion complete, Miles immediately declared entry into this turn's Battle Phase, commanding the newly evolved D/D/D monster to break through the deadlock in the name of Caesar.
"Fusion versus Xyz! My attack target is [Number XX: Utopic Dark Infinity]! Go—[D/D/D Wave Oblivion King Caesar Ragnarok]!"
Choosing the 4000-ATK Dark Infinity as the battle target, Caesar Ragnarok gathered terrifying judgmental energy in its grasp, standing in absolute arrogance.
Sylvia warned sharply, "Battling Hope with a monster that only has 3200 Attack will lead to nothing but self-destruction!"
"The one who'll be destroyed in the end is you!—I activate the effect of [D/D/D Wave Oblivion King Caesar Ragnarok]!" Miles declared.
[Once per turn, when an attack is declared involving this card: You can target 1 other "D/D" or "Dark Contract" card you control; return it to the hand, and if you do, equip 1 face-up monster your opponent controls to this card, except the battling monster.]
"By Caesar Ragnarok's effect, I return [Dark Contract with the Gate] to my hand, and equip one of your monsters!"
Miles raised his arm and pointed straight toward the [Neo Blue-Eyes Ultimate Dragon] on Sylvia's field—the very monster that had been Special Summoned from the Graveyard by Number XX: Utopic Dark Infinity's effect.
"Come back to me, Ultimate Dragon of my friend!"
"Neo Blue-Eyes Ultimate Dragon got stolen back again!" Irena cried out.
Using Caesar Ragnarok's effect to equip Neo Blue-Eyes Ultimate Dragon meant that the Ultimate Dragon had effectively returned to Miles' side of the field.
"And now, the effect of [D/D/D Wave Oblivion King Caesar Ragnarok] while it has an equipped monster!"
[This card gains ATK equal to the combined original ATK of the monsters equipped to it by this effect.]
"The strongest Ultimate Dragon has now become the blade of the Wave Emperor, cleaving sin and punishment alike!"
The pure white radiance of the Ultimate Dragon enveloped Caesar Ragnarok's body, forging a dazzling blue dragon greatsword in its hands.
"—Ultimate Wave Blue-Eyes Sword!!"
[D/D/D Wave Oblivion King Caesar Ragnarok, ATK: 3200 → 7700]
"Seven thousand seven hundred Attack?!" Sylvia staggered backward in disbelief. "The power of demons… even absorbing the White Dragon as well…"
"'Don't be so naive. Not every monster that reaches your field will obey you!'"
"The pride of the Dragon of Light is still in my hands!" Miles thrust his arm forward. "With this strike, shatter [Number XX: Utopic Dark Infinity] and claim victory!"
"No! Bearing the sacred duty of purifying sin, I absolutely cannot be defeated before the gods!"
At the final clash, Sylvia flipped over her last set card.
"—I activate the Trap Card [Malefic Claw Stream]!"
[If you control a "Malefic" monster: Target 1 monster your opponent controls; destroy that monster.]
"The counterattack of sin! By Malefic Claw Stream's effect, destroy [D/D/D Wave Oblivion King Caesar Ragnarok]!"
"So that's your last card, huh? What a shame… it won't work on D/D/D!"
Chaining to Sylvia's Trap activation, Miles flipped open the final face-down Trap on his field.
"The third Contract! Etch D/D/D's way of battle into your eyes!—I activate the Continuous Trap Card [Dark Contract with Errors]!"
[Once per turn, if you control a "D/D" monster: You can negate all Trap Card effects on the field (other than this card's) for the rest of this turn (even if this card leaves the field).]
"In the name of [D/D/D Wave Oblivion King Caesar Ragnarok], I decree—where the king's authority reaches, Traps are forbidden!"
Miles directly sealed all Trap Card effects on the field with the Contract, naturally including the chained [Malefic Claw Stream].
[Malefic Claw Stream effect negated]
With Sylvia's final Trap blocked by the Contract, Caesar Ragnarok swung the Wave Blue-Eyes Sword, bringing down the Emperor's judgment.
"Explode☆Slay! The End of Judgement!!"
[Number XX: Utopic Dark Infinity destroyed]
"Ughhhhhhh!"
[Sylvia, LP: 3250 → 0]
Struck head-on by the raging greatsword, Sylvia's Life Points instantly dropped to zero. She closed her eyes, accepting the resolve of the defeated.
"O gods… if this too is a trial I must endure, then please grant me the courage to bear this defilement~"
