Among the twelve Beast Vassals of the Fourth Primogenitor, the Third holds a uniquely special power.
Unlike the other Beast Vassals, whose abilities require active magical activation or specific conditions, the Third's Dimensional Devourer needs neither deliberate invocation nor prerequisites—its power manifests simply by biting down.
Whether tangible or intangible, anything caught between its jaws is utterly annihilated from space itself, including space as a concept.
This is the ability of Al Meissa Mercury—less a wielded power and more an innate trait of the twin-headed dragon itself.
Thus, even when fully materialized, the dragon's devouring capability remains intact. Its fangs tear through even the most indestructible substances, consuming them without a trace.
And so, the colossal dragon pinned the horned serpent beneath its claws, its elongated necks twisting violently as it ripped and feasted upon the writhing monstrosity. The serpent's agonized shrieks shook the earth, turning the battle into a primal clash of titans—no longer a contest of esoteric abilities, but raw, visceral savagery.
The serpent attempted to retaliate, gathering searing flame in its maw to blast the dragon away—
"ROAR—!"
—only for the Minotaur to slam its magma-wreathed axe into the ground. The earth trembled, then erupted in molten spikes that impaled the serpent's limbs, nailing it to the scorched battlefield.
Cor Tauri Succinum had always possessed dominion over lava, reshaping the very earth into weapons. The Foreign World Erosion could negate supernatural forces, but against physical magma spears forged from the land itself? Useless.
In truth, Rozen hadn't even needed to materialize his Beast Vassals as Familiars to win.
The Second's power alone was a natural counter to the erosion.
After all—
"The Fourth Primogenitor was the one who slew the God of Sin. Did you truly think her power wouldn't have a means to crush his legacy?"
The Second's lava manipulation wasn't just destructive—it was designed to breach the Foreign World Erosion's defenses.
From the beginning, the Cleansers had been doomed.
"Now, exit the stage."
Rozen's body shimmered with crimson mist once more as a third Beast Vassal took form.
"Minelauva Iris."
A Valkyrie clad in ethereal armor materialized, her rainbow-hued greatsword gleaming ominously. With a single beat of her blazing wings, she shot forward—
—just as the twin-headed dragon and Minotaur God leapt away, clearing the battlefield.
The Valkyrie's sword fell.
"SHINK—!"
A prismatic slash split the air.
For a heartbeat, the horned serpent froze.
Then—
CRACK. CRACK. CRACK.
Like petrified stone, its body shattered.
Every absorbed entity—every replicated weapon, every wyvern, every mechanical puppet—disconnected from the whole, forcibly severed by the Valkyrie's causality-severing strike.
BOOM!
The serpent exploded into fragments: shattered helicopters, mangled armored vehicles, scattered Knights of the Sinful God—even the replicated cursed artifacts reverted to inert copies.
Among the wreckage, the spear-wielding knight collapsed, his armor in ruins, his lance clattering against the scorched earth.
Battle over.
With triumphant roars, the three Beast Vassals dissolved into mist.
Rozen exhaled, watching the defeated Cleansers with detached amusement—
"Senpai!"
"Your Highness!"
Yukina and Yuiri arrived atop the swamp dragon, which bellowed victoriously as it soared toward Rozen, as if claiming credit for the win.
Vatler and Iblisveil observed the scene from afar.
"It seems our intervention was unnecessary after all."
Vatler sighed, equal parts disappointed and satisfied. While denied a full battle, witnessing Rozen's prowess had been its own reward.
Iblisveil's crimson eyes narrowed.
"So this is why the Original fell to him... and why even that hag from the Chaos Zone suffered losses."
Mastery over the Fourth's Beast Vassals? A Primogenitor-tier mana pool? Those were impressive, but secondary.
The true threat was Rozen himself—a human who could materialize Beast Vassals as Familiars at will.
"If the rumors of him fusing Beast Vassals like you are true..." Iblisveil glanced at Vatler.
"They are." The Duke of Ardeal grinned. "And he wasn't even serious today."
That fact alone made the spectacle worthwhile.
For Iblisveil too, it had been... enlightening.
"The Witch's little brother. Fascinating."
With a snap of his demonic wings, the prince turned away.
"Not claiming the dragon, Your Highness?" Vatler called mockingly.
Iblisveil didn't bother looking back.
"I've no interest in stealing another's spoils."
His silhouette vanished into the horizon, leaving Vatler to lick his lips in anticipation.
After all—
The power Iblisveil had gained by devouring his elder sister... now that was a worthy opponent.
"Someday, Iblisveil Aziz... we will dance."
Behind him, mist coalesced into two familiar figures.
"Our apologies, Lord Vatler."
"We failed to assist."
Tobias and Jagan bowed, their wounds freshly healed.
Vatler waved them off.
"No matter. The harvest was bountiful regardless."
He hadn't obtained the dragon or the cursed artifacts, but the truth Rozen had let slip earlier?
Priceless.
"To think... he absorbed the Fourth's power after destroying her."
The vampire's smile turned rapturous.
"Oh, the chaos this revelation will bring."
With a laugh, he too dissolved into the night.
