I Took A Succubus's First Time

"Is that... the President...?"

Yumi's breath hitched as her eyes widened in sheer disbelief. The sheer force of the attack had been overwhelming, shaking the very air around them. She turned to the one responsible—Yuuna—who stood unwavering just a few feet from the Love Link container.

"Her power... it's increased this much?" Misuzu whispered, her hands trembling slightly. Her gaze flickered between Yuuna and Kouhei, who remained encased within the container's protective glow. "Is this... the true extent of Okumura-kun's power?"

Yuuna exhaled, her voice steady and resolute. "Thank you for holding her off. Now, I'll finish this."

As she spoke, a surge of crimson mana swirled violently around her palm, forming a seething, swirling mass of pure destructive energy. The air crackled with intensity, distorting the space around her as if reality itself was bending beneath the pressure.

Her sharp eyes locked onto the corrupted one, whose form remained obscured by the smoldering remnants of the earlier explosion. The aftershocks of the Crimson Rose still lingered, its residual mana crackling like dying embers in the air.

Then—

A single slash cut through the haze.

The corrupted one's blade effortlessly sliced apart the smoke and residual energy, dispersing them in an instant. Her figure emerged from the dissipating shroud, her presence radiating an oppressive, suffocating aura.

"You... you dare do this to me?!" she snarled, her voice guttural with fury.

Her body had undergone a monstrous transformation—her once-human flesh now sickly crimson, pulsing with veins of writhing, dark energy. Her eyes glowed with malevolence, their eerie light piercing through the dim battlefield. A thick, suffocating aura oozed from her form, pressing down on everything around her like a massive unseen hand.

She had grown stronger. Far stronger than before.

The brief moments Yuuna and Kouhei had spent performing the Love Link had given her the time she needed to evolve into something even more grotesque.

"I will kill you all!" she shrieked, her voice warping into a frenzied, unnatural pitch. "Not a single one of you will leave this place alive!"

Her hysteria was maddening—like the deranged wails of something far beyond human comprehension. An unhinged fury that no sane person could possibly possess.

"Crimson Dance!"

Yuuna didn't hesitate. With a sharp command, her most powerful technique roared to life.

High above them, the sky twisted as a colossal vortex of crimson mana materialized. The swirling mass pulsed with an ominous glow, distorting the air with its sheer intensity. Then—like the executioner's final decree—countless razor-sharp crimson nails materialized, suspended ominously in the air, all aimed directly at the corrupted one.

Yuuna's fingers pointed downward.

The air trembled.

And then—

The crimson nails descended like a storm of divine judgment.

"RAAAAAAGHHHHH!!"

The corrupted one roared in defiance, swinging her blade in an attempt to intercept the onslaught. But they were too fast. Too relentless. Before she could even complete her swing, the nails struck her in rapid succession.

Each impact was like thunderclaps against flesh.

She reeled back, her body spasming as the crimson nails tore into her—merciless, unyielding. The sheer force sent shockwaves through the battlefield.

Blood.

Crimson ichor burst from her wounds as the piercing projectiles impaled her body. The corrupted one staggered, her knees buckling beneath her as she crashed onto the ground.

And yet—

She refused to fall completely.

"You... piss me off..." she growled, her breath ragged. "I don't know why, but you do!"

Her voice trembled—not with fear, but with pure, festering hatred.

"Why won't you just understand?! Why do you keep flaunting yourself?! Why do you always act like you're better than me?!"

Yuuna's expression remained cold. There was no hesitation in her next move.

A second Crimson Rose formed in her palm, its radiance intensifying with the sheer weight of the mana she was feeding to it.

The stronger her emotions, the more devastating her attacks became. She could not afford to drag this battle on any longer.

With a swift motion, she hurled the explosive energy toward the corrupted one. The instant it made contact—

BOOM.

A massive detonation erupted, consuming the corrupted one in a raging inferno of crimson destruction. The ground trembled beneath the sheer magnitude of the blast. Dust and debris shot into the air, obscuring everything in a haze of devastation.

And yet—

From within the inferno, a silhouette remained.

The corrupted one still knelt upon the ground, her body battered and burned, but her expression unchanged.

It was as if nothing had fazed her.

"You're making me angrier… and angrier..." she whispered, her voice dripping with venom. "I'm going to kill you all... I will..."

Then—

A grotesque tearing sound filled the air.

From her back, something erupted.

A new pair of arms burst forth.

And then another.

Now, she had six arms in total—each one writhing unnaturally, their elongated fingers curling like claws.

But that was not all.

Her entire body had begun to shift—growing taller, more imposing.

A monstrous entity had begun to take form.

The sword, a grotesque abomination of writhing flesh and pulsating veins, fused with the corrupted one's body as if it were a natural extension of her being. The agonized faces embedded within the blade twisted and contorted, their hollow eyes brimming with torment as they sank into her flesh. Now, she bore four faces—two on either side of her head, one in the front, and another at the back of her head. Each one moved in eerie synchronization, their mouths curling into wicked, unnatural grins.

"I will kill all of you!"

Her voice tore through the air, raw and inhuman. The other faces echoed her declaration, their tones distorted, overlapping in a nightmarish chorus that sent a chill through the battlefield.

"She's getting stronger and stronger..." Yuuna muttered, her crimson eyes flickering with urgency. "I have to finish this!"

Without hesitation, another Crimson Rose bloomed in her palm, its burning petals swirling in a vortex of volatile energy. She hurled it toward the corrupted one, the searing force distorting the very air around it.

But just as it neared its target—

A monstrous growl erupted from the corrupted one. A pulse of dark energy exploded outward, sending shockwaves rippling through the battlefield. The sheer force of her aura alone repelled the Crimson Rose, blasting it back into nothingness.

Yuuna cursed under her breath. She had no time for hesitation.

"Crimson Dance!"

The moment the words left her lips, a cyclone of crimson mana surged into existence. Blades of light wove through the air, spiraling in a chaotic symphony of destruction. Each flickering streak of mana carried the weight of death, hungry for its target.

The technique was a drain on her mana reserves, a power so immense that repeated use could leave her defenseless. Yet, with the boundless energy coursing through her veins—granted by Love Link—she could unleash it again and again without faltering.

She did not hesitate.

"Crimson Dance!"

A second wave of slashing mana erupted forth, merging with the first. The twin barrages shot toward the corrupted one in a brilliant, spiraling storm of devastation.

But—

The monstrous entity did not flinch.

Raising all six of her grotesque, sinewy arms, she blocked the onslaught. Blades of energy tore through flesh and muscle, severing limbs with sickening ease.

And yet—

Before Yuuna could react, the mutilated flesh pulsed and twisted—new arms sprouting from the stumps like writhing serpents.

A wave of dread settled in her gut. This would not be an easy battle.

"Raaaaaaghhhh!"

With a feral shriek, the corrupted one launched herself forward, closing the distance between them in an instant. All six arms pulled back, each one tensed and ready to deliver a devastating blow.

But before she could strike—

Kozue stepped in.

A radiant barrier materialized around Yuuna, shimmering like a crystalline shield. The corrupted one's blows landed with earth-shattering force, sending tremors through the air. Cracks splintered across the protective shield, spiderwebbing outward from the point of impact.

Yuuna knew she had seconds at most.

Before the barrier could fully shatter, she leapt away, narrowly evading the corrupted one's reach.

The moment she touched the ground, Kozue's barrier burst apart, its fragments dissolving into fading light.

Yuuna turned to face her opponent once more.

The corrupted one stood amidst the remnants of the barrier, her freshly regenerated limbs twitching, brimming with dark energy.

"It looks like this is going to be harder than I thought," Yuuna murmured. Her heartbeat was steady, but her mind raced.

This was no longer a battle against a human.

This was a battle against a nightmare given form.

But she was not done yet.

"Crimson Gate!"

A colossal surge of mana erupted from her body, shaking the very air. The ground beneath her feet glowed with brilliant crimson light as an intricate magic circle carved itself into existence.

The corrupted one's eyes widened—then darkened with fury.

"Raaaaaaaaaaghhhhhh!"

She charged forward once again, a blur of pure malice.

But Kozue was ready.

A second barrier manifested, locking Yuuna behind its radiant shield. The corrupted one collided with full force, her rage-fueled onslaught hammering against the protective wall.

Cracks instantly spread across the surface.

"I can't... hold it much longer...!" Kozue gasped, pouring every ounce of her mana into reinforcing the barrier. She gritted her teeth, forcing herself to endure.

But it wasn't enough.

The barrier shattered.

"Hnnng!?"

The backlash sent Kozue hurtling backward, blood erupting from her lips as she crashed onto the battlefield.

"Graggggghhh!"

The corrupted one, undeterred, lunged for Yuuna—her clawed hands aiming for the kill. She lunged—

But she was too late.

Yuuna had finished her spell.

Her eyes snapped open.

"Raaaaaaaaaaaaaaaaaah!!!!"

A blinding explosion of crimson light erupted from above.

Like divine retribution, the radiant force descended upon the corrupted one, engulfing her in an all-consuming inferno of destruction.
