After Scáthach charged forward, the Round Table Knights—Artoria Pendragon, Merlin, Gawain, Galahad, Kay, Tristan, Melusine, Baobhan Sith, and others—also launched their attacks.
The collective might of their assault was truly immense.
Yet even so,
against Oberon, whose body stretched thousands of kilometers across the sky,
their efforts were but a drop in the bucket.
Scáthach's spear pierced through Oberon's body,
but
the small wound did nothing to hinder the insect dragon's movements.
It opened its maw, ready to continue devouring all things around it.
"What can we do to stop this?"
Artoria, seeing her Excalibur once again fail to produce results, turned to Merlin and asked.
"In this situation, I can't think of a solution either. This Oberon isn't acting alone—Gaia itself supports him from behind. His power is utterly terrifying." Merlin smiled bitterly.
Then, after a moment of thought, he said to Artoria,
"At this point, perhaps only those two who haven't appeared yet can resolve this."
"Huh?"
Hearing this, Artoria suddenly realized—after all this time speaking with Merlin, after Oberon's prolonged appearance—
two people were conspicuously absent.
Lot and Morgan had not shown themselves at all.
Did they flee?
Artoria refused to entertain the thought.
They would never do such a thing.
"Then... are they searching for a solution?" Artoria asked.
"Or perhaps it is precisely their actions that drove Oberon to this state," Merlin added.
"...For now, we can only hope Sister and Brother-in-law appear soon," Artoria prayed.
Meanwhile,
the insect dragon's devouring continued unabated.
The group could barely maintain their footing, resisting the force pulling them skyward.
But
as the suction grew ever stronger, Artoria and the others began to lose their grip.
On the verge of being swallowed, Merlin said to Artoria,
"It seems we must prepare to fight on the other side."
To not fight in this world... how unsatisfying!
Artoria thought to herself.
Just then, she felt a droplet of water land on her ahoge.
Hm?
What's this?
Rain?
As she wondered, she raised her head—
and saw a river flowing across the sky.
...What in the world?
Artoria was stunned by the sight.
She wasn't alone; everyone, even Oberon, was shocked.
A river in the heavens.
None could comprehend what they witnessed.
"Wait—there are people up there!"
Scáthach, with her keen eyesight, spotted two figures riding the river's current.
"It's Their Majesties, Lot and Morgan!"
Tristan shouted, pointing at the two standing atop what appeared to be a surfboard.
Then, the river descended, cascading from the sky.
Oberon's massive size meant the torrent crashed directly upon it.
Meanwhile, Lot and Morgan descended gracefully.
"Hey, if we ever become Heroic Spirits, this should unlock our swimsuit variants," Lot remarked to Morgan.
Then, glancing at the colossal insect dragon, he asked,
"What's going on? What got this guy so worked up?"
"Because this world will soon no longer belong to it."
Da Vinci's hologram appeared at that moment.
Gazing at the river of time, she said with a complicated expression,
"Now I understand why this place felt so strange. It's not a Singularity, nor is it a parallel world. This river of time is the anomaly."
"Explain," Lot urged.
"Originally, this was a Singularity—a place destined to diverge from Proper Human History. But another timeline exists here, one not rooted in our original world."
Da Vinci looked at Lot, her eyes filled with realization.
"It seems we need not fight any longer. If this timeline perfectly synchronizes with this world, it will become a true parallel world to ours. We could even establish communication and exchange resources."
"Sounds good to me," Lot mused, stroking his chin.
"But how do we make it happen?"
"That part is already simple."
Merlin and Scáthach approached.
Scáthach wore a smile, while Merlin's expression was bittersweet.
He knew that once the timeline shifted, his Clairvoyance would vanish.
Scáthach's would too—but for her, that was a blessing.
An unknown future held far more intrigue.
"Now, defeat that insect dragon!"
Scáthach pointed at Oberon, now weakened to its limits.
"How are we supposed to beat that thing?"
Lot grimaced at the sheer scale of their foe.
But Morgan smiled confidently.
"That part is easy."
She turned to the Chaldean group.
"I'll need your assistance now."
"What kind?"
"Lancelot and Agravain are still in Ireland, correct? I demand their oath of fealty to me."
Morgan's words made Fujimaru Ritsuka pause—then nod in understanding.
She knew Morgan's goal now.
She
would become the Island's sovereign.
Ritsuka had maintained contact with Ireland.
After conveying Morgan's terms, Agravain nodded solemnly and knelt before her.
"Understood, Your Majesty Morgan. Ireland pledges its loyalty to you."
"Good."
Morgan acknowledged, then added upon seeing Agravain's dour expression,
"Rest assured—the 'you' of this world won't suffer as you did."
"...Thank you."
Agravain smiled faintly.
With all of Britain now under Morgan's rule, her power surged exponentially.
She turned to Lot.
"Come, husband. Let us strike the blow that will defeat Gaia itself."
"Gladly."
Lot took her hand, their energies merging seamlessly.
"Gungnir. Joyeuse."
"Now is the time to unleash your true might."
As they spoke in unison,
twin beams—one crimson, one prismatic—lanced toward Oberon.
Piercing.
Annihilating.
Triumphant.
...
Twenty Years Later
The Mediterranean Sea.
A ship drifted lazily under the sun.
On its deck lounged four figures: three women and one man.
The blonde glutton eyed her sister and brother-in-law with exasperation.
"Are we really doing this? After defeating the Sword Emperor Lucius and conquering the Roman Empire, we just handed everything over to Gawain, Agravain, Gareth, and Mordred? Is that really okay?"
(Mordred had been born in this world too—but as Lot and Morgan's child. Artoria had played no role in her creation.
Not that she could have.)
"Of course it is! Retirement is meant to be enjoyed."
Lot waved dismissively.
"First, we tour the Mediterranean. Then, we visit Chaldea's world. With both the Incineration of Humanity and the Alien God resolved, it'll be pure vacation. Decades without gaming—I'm starving for it!"
He then glanced at Artoria.
"Speaking of, aren't you supposed to be leading the Round Table? Retiring too?"
"Simple. I want to taste future cuisine from around that world."
Artoria drooled visibly.
Morgan facepalmed.
Even now, my sister remains this embarrassing...
Beside them, Scáthach—in a swimsuit—added,
"I joined this voyage to observe the other world. You won't throw me overboard, little sister?"
"Don't be absurd."
Morgan's tone was fond. Time had long since turned this sister-in-arms into true family.
Just then, Guinevere—wearing an OL uniform—approached.
"Your Majesties, dessert is served. Dinner begins now."
"Eh? I'm not a king! Don't call me 'Majesty'!" Artoria protested.
"Then none for you," Guinevere replied flatly.
"Wha—?!"
Artoria's despair amused the others greatly.
Guinevere relented with a sigh.
"Fine, you get some too."
"Phew... That's a relief."
Artoria smiled.
