"Of course, to test your weight."
With her right hand half-lifted, the back of her fingers resting on her hip in a triangular pose, Inner Moka struck a stance like a model, curves accentuated to perfection.
Her cold, magnetic, mature voice rang out.
Calm, composed, with not a hint of haste.
A faint arc tugged at her lips, a trace of a smile—
like a hunter catching sight of her favored prey.
Her demonic aura receded, and the scarlet Blood Moon Domain that had stretched for kilometers instantly vanished.
"Then let's start the battle."
Arthur stood with both hands in his pockets, a faint smile curling at his lips.
The moment his words fell—
A blood-red flash sparked across Inner Moka's body. With just a light step forward, she vanished from sight.
In the next instant, she appeared before Arthur.
Her right fist lashed out, aiming squarely for his chest.
When the punch was still twenty centimeters away—
Boom!!!
The sound was like muffled thunder exploding.
A shockwave burst outward in all directions.
That powerful strike slammed into a nearly invisible, pale-blue crystalline barrier.
It was the Sanctuary Shield conjured from the Blue King's Authority.
A domain cast by a King's Authority—its defenses could withstand even a nuclear bomb.
Though Inner Moka's punch carried great force, it wasn't nearly enough to shake the Sanctuary Shield.
"Not bad."
Seeing this, her smile deepened slightly.
That blow had only carried a tenth of her strength.
It was merely a probe.
She knew Arthur wasn't simple, but not how strong he truly was.
And she didn't want to accidentally kill him with a full-force strike.
"Use a little more strength. I can handle it."
Arthur's smile remained, his hands still tucked casually in his pockets.
"Ohhh~~~"
At that, Inner Moka's eyes narrowed slightly.
No doubt about it, that was a provocation.
Even if her True Ancestor power wasn't fully awakened, among the myriad yokai clans of the Demon Realm, vampires were seated at the very top—
the apex predators, called the Great Demons of Might.
And yet Arthur dared tell her to use more strength.
As if to say she didn't even hit hard enough.
That was something she couldn't just ignore.
Just as she was about to unleash half of her power—
"Wait, let me set the stage first."
Arthur suddenly interrupted her.
Inner Moka frowned slightly but reined in her attack.
"Domain Expansion—Sovereign's Realm!"
Arthur's voice was soft, yet the first invocation of the Supreme King's Domain carried boundless force.
As his words fell, he slowly reclined backward into a seat that hadn't been there before.
An invisible, overwhelming power exploded outward.
The space within a hundred meters was instantly severed from the main world, transforming into an entirely independent realm.
Above and all around, the starry vastness of the cosmos reflected endlessly.
The ground turned into rolling green meadows, grass as lush as velvet.
In that moment, a golden throne, engraved with all the beings of creation, materialized.
Arthur sat upon it, serene and unhurried.
The throne lifted him high into the air.
Seven swords of Damocles stood suspended to his sides and behind him.
His arms rested casually on the throne's arms. His body tilted slightly, cheek propped on the back of his right hand—
the posture reminiscent of a queen at leisure.
A golden crown manifested above his head, set with seven jewels, each one corresponding to a different Authority.
Like a halo of divinity, it hovered above him.
In that instant, Arthur seemed to become a true emperor.
High above, gazing down upon all life.
An unseen pressure radiated outward from him, filling the entire space.
Like the descent of a god.
Transcending all existence.
Sacred, supreme—unfit to be gazed upon directly.
"This is…!!"
Witnessing it, Inner Moka's eyes widened slightly, shock flashing in her gaze.
She had to admit—
The sheer aura of this move was staggering.
When her eyes locked with Arthur's, she felt an inexplicable, fleeting urge… to kneel, to submit.
Even if only for a moment.
But that was unbelievable.
She was no ordinary monster, but a True Ancestor Vampire.
A True Ancestor—
a being in demonfolk legend said to rival the gods themselves.
Even though her true power remained sealed…
To merely meet Arthur's gaze and feel a tremor of submission in her heart?
That was unthinkable.
Looking down upon her with a faint smile of absolute control, Arthur said simply:
"Let's begin."
His tone was calm, almost dismissive.
As though this were nothing but a minor play unfolding before him.
Where he had been the challenger before, now the roles seemed reversed—
She was the one standing trial before him.
"..."
Inner Moka frowned, an odd flicker of irritation rising in her chest.
"Then let me show you… the true might of the Great Demon of Power."
Her words were little more than a whisper, but her battle instincts burned like wildfire.
Her demonic aura surged violently, transforming into a blazing blood-red flame around her.
A crimson flash erupted—
and she was gone.
The next instant, she appeared high in the air, hurtling toward him.
Her fist drove forward, carrying enough force to pulverize a skyscraper.
This punch was nearly her full strength.
The very space around it seemed to warp and distort.
Yet Arthur's expression didn't change.
A golden gleam flickered in his eyes.
When her fist was only ten centimeters away, a translucent golden ripple spread out before him.
"This is…???"
Inner Moka's eyes widened in disbelief.
Arthur was right in front of her—
and yet suddenly felt impossibly distant.
Her punch connected with the golden ripple.
The immense destructive force was absorbed, dissipated into the endless depths of space.
At that moment, Arthur sat up straight.
He raised his right hand—
and gently caught her pale, delicate fist.
With a light tug, he pulled the stunned Moka forward, straight into his embrace.
Seated on his left thigh, her slender waist caught securely in his left arm.
"Still want to keep trying?"
Arthur's voice was soft by her ear, almost tender.
Suppressing her shock, Inner Moka turned her head, lips curling into a faint smile.
"You win."
She made no move to resist.
Her goal had only been to test Arthur's strength.
The result hardly mattered.
No matter what happened, she had already resolved to become his Servant.
After all, she had promised.
Their eyes locked.
Arthur leaned in, capturing her soft lips.
A faint blush flickered in Inner Moka's eyes—
but the next instant, she turned the tables, responding not only boldly, but taking the offensive.
Arthur: "(???)"
As expected of the strong-willed Inner Moka—decisive and uncompromising.
Neither of them gave an inch.
Their clash became a fierce battle of tongues.
After about ten minutes—
Inner Moka reverted to Outer Moka.
The sealing cross automatically returned to its place.
"Wha—?!"
Without the shared memory of moments before, Outer Moka blinked wide-eyed.
What happened?!
The last thing she remembered was Arthur casually removing the seal.
And now… why on earth was she kissing him?!
She didn't have time to untangle it.
All she could do was drown in the strange, intoxicating sensations Arthur brought her.
Unlike Inner Moka's boldness, Outer Moka's kiss was timid, passive.
She only clumsily followed his lead.
Meanwhile, Arthur quietly began the ritual of the King's Servant Contract.
The formless power of the Supreme King's Authority poured into Akashiya Moka's body.
Touching both her Outer and Inner selves.
Neither showed the slightest resistance.
The power coursed through her, gathering at her lower abdomen.
There, it crystallized into a violet sword-shaped sigil edged in gold—
invisible to ordinary eyes, yet fused inseparably with her soul.
The King's Servant Contract was complete.
