What is this Dimensional Chat???

Kuoh Academy

Kuoh, Japan

The air crackled with tension as Valiana's words hung over the battlefield, sending a shockwave of disbelief through those who heard them.

Valiana smirked at their stunned faces, reveling in the chaos she had sown. To prove her words, she spread her eight devils wings and ascended gracefully—her dragon wings, a gift from Divine Dividing, adding to her menacing aura.

"The proud leader of the Fallen Angels has fallen," she declared mockingly. Her piercing gaze settled on Issei Hyoudou. "And now... it's your turn."

She floated down, each step deliberate as she approached Issei, her eyes gleaming with a cruel amusement. "I already know everything about you. Your parents? Ordinary humans. You? Just another pathetic devil. If it weren't for Boosted Gear, you'd be utterly forgettable."

Issei's fists clenched. He could feel his blood boiling.

"What should I do to make you more motivated?" Valiana mused, tilting her head. Then, her smile turned vicious. "Ah... I know. Let's use revenge."

His eyes narrowed. "What are you trying to say?"

Valiana leaned in slightly, voice dropping to a chilling whisper. "How about I kill your family and friends? Once I wipe them out, you'll have nothing left—nothing but hatred. I heard revenge makes people stronger. What do you think?"

Issei's aura flared. A red energy burst from his body, his fury fueling his transformation. In an instant, he entered his Balance Breaker form.

"Issei! Don't let her get to you!" Rias shouted, her voice urgent.

"Buchou's right!" Akeno added, concern lacing her words. "Stay focused, Issei-kun. She's trying to break you!"

Koneko's small frame trembled. 'Valiana-san, that's enough... please stop,' she thought, but she knew her pleas would be ignored. Instead, she turned to Issei. "Don't let hatred control you, senpai. It'll only lead to your downfall."

Valiana merely chuckled. "Look at him, Albion. Fueled by rage and desperation. This is the power I've been waiting for."

Albion hummed in agreement. "Indeed... This battle might prove to be entertaining after all."

"Enough talking!" Issei roared, his crimson aura intensifying as he lunged at Valiana, fists flying.

She barely flinched. With practiced ease, she engaged her technique—Defensive Kun-Lun, a masterful relaxation technique that let her absorb attacks without sustaining damage. Issei's punches landed, but she remained unfazed.

"Not bad," she admitted. "Who taught you martial arts?"

Issei gritted his teeth. "Shin-san did! And I've only gotten stronger since we last fought!" He raised his arm. "Today, I'm taking you down for hurting my friends! Ascalon!"

A golden glow engulfed his arm as he summoned Ascalon, the holy sword bestowed upon him by Archangel Michael. Without hesitation, he swung relentlessly at Valiana, each strike carrying the weight of his anger.

Valiana smirked, effortlessly dodging. "Ascalon, huh? The holy sword wielded by Saint George himself to slay a dragon... Interesting toy. But your movements are sloppy."

Before Issei could react, she struck—one devastating blow to his abdomen. His Balance Breaker shattered instantly.

"AGHHH!!" Issei coughed up blood as he crashed onto the ground.

Valiana hovered over him, unimpressed. "You talk about protecting your friends... but how can you when you're this weak? You still don't even understand how to wield Ddraig properly." She sighed. "Pathetic."

"Oi! Partner!" Ddraig's voice echoed in Issei's mind. "You better not go down from just one hit! Get up!"

"Issei!!!"

Rias and the others rushed to his side, only for Valiana to casually send them flying back with a flick of her power.

"Kiba! Xenovia! Stall the White Dragon Emperor!" Rias commanded, desperation lacing her tone. "Asia, tend to Issei's wounds!"

Asia rushed forward, hands glowing with the soft light of Twilight Healing. "I'll do my best, Rias-sama!"

Xenovia tightened her grip on Durandal, its holy blade humming with divine energy. She stepped forward, unwavering. "We can't let her reach Issei. Not while he's still vulnerable."

Kiba stood beside her, his Sword of Betrayal gleaming under the moonlight. He exhaled, steadying his breathing. "Valiana is relentless… but we've faced worse." His eyes hardened. "We can do this."

Valiana smirked as she summoned a mystical twin-bladed weapon, a gift from her husband, embedded within her Sacred Gear. Her fingers tightened around the hilts, anticipation gleaming in her piercing eyes. With a swift motion, she activated Manta Style, her form splitting into three identical copies. Each illusion moved with the same grace and precision, weaving through the chaos like specters of destruction.

"Take care of these nuisances," she ordered, her voice cold and unwavering.

Her clones darted forward, effortlessly bypassing Rias' knights—Kiba and Xenovia.

"What the—?" Kiba and Xenovia gasped in unison, their reflexes barely catching up to the blinding speed of Valiana's illusions.

Each clone struck with ruthless efficiency, every slash dispelling the energies around them. Their movements were a blur, each one indistinguishable from the original. The sheer speed and coordination of Valiana's attack left her opponents staggering.

Rias' eyes widened in horror. "No… Kiba, Xenovia!"

From the sidelines, Azazel's sharp gaze locked onto the mysterious weapon in Valiana's hands. His brow furrowed. 'What is that blade?' Even with all his knowledge, he had never seen such a weapon in this world. He gritted his teeth, pain flaring through his body from his injuries. "Damn it… My wound is too deep. I just hope they can hold her off until I recover."

Valiana's lips curled into a confident smirk. "You think you can challenge me? They don't call me The Strongest White Dragon Emperor in history for nothing." Her gaze snapped to Issei. "Prepare to meet your demise."

A crackle of electricity filled the air.

"You'll have to get through me first."

Akeno stood firm, her violet eyes gleaming with defiance. Lightning arced across her fingertips, illuminating her elegant yet deadly form.

Valiana scoffed. "Baraqiel's daughter, huh? You don't even have the resolve to use your full power, let alone stand against me. Move aside trash before I erase you from existence."

Akeno's expression darkened, her body trembling—not with fear, but with fury.

"Never… speak his name in front of me!!!"

A furious storm of lightning erupted from her hands, the sky splitting open with raw energy. The ground trembled under the sheer magnitude of her power.

But Valiana remained unfazed. She raised a hand.

"Magebane Mirror."

A shimmering, translucent barrier enveloped her body, reflecting Akeno's attack back at her with twice the force.

"Kyaaaaa!!!"

Akeno screamed as her own lightning surged through her body, sending her crashing to the ground, unconscious.

"Akeno-san!" Issei shouted, his heart hammering. He tried to move toward her, but his body was still battered from Valiana's earlier attack. He could barely stand.

Ddraig growled in frustration. "Damn you, Albion! I don't remember you having abilities like this. How can your host be this powerful?"

Albion's amused chuckle echoed in response. "Oh? Are you admitting that I'm better than you, Ddraig? Hahaha!"

"In your dreams!" Ddraig snapped. "Come on, partner! Let's show them our combined power!"

Issei gritted his teeth, determination flaring in his eyes. He turned to Rias. "Buchou, get ready!"

[Boost! Boost! Boost! Boost! Boost! Transfer!]

A surge of power flooded into Rias, her crimson aura igniting like wildfire. The air around her grew heavy with sheer magical pressure, the temperature rising as an inferno of destruction built up within her.

Her usual calm demeanor was gone, replaced by an unrelenting fury.

"I am Rias Gremory," she declared, her voice carrying regal authority. "Heiress of the Gremory Clan and the Crimson Empress. And you… will regret underestimating us!"

She raised her hand, dark energy swirling like a vortex of death.

"Crimson Extinction!!!"

Pillars of demonic power erupted from the ground, their intensity rivaling the very flames of Hell. Each column of energy surged toward Valiana with lethal precision.

Valiana's confidence wavered for the first time. "Tch! Something like this is—"

Her body suddenly froze.

"W-What?!"

Her limbs locked in place, her movements completely paralyzed. A sinister crimson glow reflected in her vision.

From the shadows, Gasper stepped forward, his eyes gleaming like blood-red orbs in the moonlight. His Sacred Gear, Forbidden Balor View, was in full effect.

"You won't hurt my friends," Gasper said, his voice trembling yet filled with resolve. "I won't let you."

Koneko watched from the side, arms crossed. "You underestimated them too much, Valiana-san. This… is going to hurt."

Valiana's eyes widened. "You—!"

BOOOOOOOOM!!!

The explosion tore through the battlefield, illuminating the night sky with a blinding flash of crimson destruction. The sheer force of it shook the entire academy grounds.

When the smoke cleared, the battlefield was eerily silent.

Issei exhaled sharply, his body trembling from exhaustion. He looked at his friends—at Rias, Gasper, Kiba, Xenovia, Akeno. Even in the face of overwhelming power, they had stood together.

"You underestimated us, White Dragon Emperor." Rias' voice rang through the air, her fiery gaze locked onto Valiana. "It's not our individual strength that will defeat you."

Issei clenched his fist, his voice filled with conviction.

"It's the power of our friendship!"

•

The school building and the surrounding area lay in ruins, reduced to smoldering rubble. Even the sky, once a vast unbroken expanse, had been violently split apart—a deep, jagged rift carved through the heavens by Black Flash's devastating attack.

A heavy silence followed, broken only by the distant sound of crackling flames and the crumbling of shattered stone.

"What… a monster," Sirzechs muttered, his usually composed demeanor shaken. His crimson eyes remained fixed on the sky, the torn abyss above reflecting in his gaze. "He split the heavens… and penetrated our strongest defensive barriers… with a single attack."

Michael's wings trembled slightly as he took a measured breath. "We cannot defeat him alone," he admitted, his voice calm yet resolute. "His power is overwhelming. His speed is beyond anything we've faced."

Serafall,, known for her playful antics, now wore an uncharacteristically serious expression. "Agreed. Charging in head-on would be suicide. We need a plan—something that can turn the tide in our favor."

A voice cut through the tension.

"We need to strike where it hurts the most—but recklessly rushing in will only get us killed," Satria's clone stated, his sharp gaze scanning the battlefield.

Serafall turned toward him, along with the other leaders. "Do you have a plan, Shin-kun?"

Satria's clone nodded. "I'll be the bait—you all observe and exploit the weaknesses I expose. You're war veterans, after all. I trust you'll find the loopholes. And…" He turned his gaze toward a certain martial artist. "Garou… help the others take down the squid-faced bastard."

"Hah?! Don't tell me what to do, asshole!" Garou snapped, folding his arms defiantly.

Satria sighed, stepping closer. He lightly tapped Garou's shoulder.

In that instant, Garou felt it—a glimpse into the abyss of power lurking within Satria. It was fleeting, but undeniable. The sheer weight of it left an impression.

Satria's eyes glowed. "I said… Help them."

A tense silence stretched between them before Garou clicked his tongue, swatting Satria's hand away. "Tch… I guess I've got no choice," he muttered. His fists clenched at his sides. "One day… I'll surpass you. Just wait."

With that, he turned and sprinted toward the raging battle with Gilles de Rais.

Now alone in the center of the battlefield, Satria took his position. His mere presence seemed to demand attention.

He closed his eyes, raising a hand toward the sky.

"May this curtain of lies vanish before my grace."

The moment the words left his lips, the sun—hidden behind the darkened sky—suddenly shone brighter. The battlefield was bathed in golden radiance, and with it, Satria's aura intensified.

At first, the spectators were in awe. But as the temperature began to climb, excitement turned into discomfort.

"Wait… is it just me, or is it getting hotter?" a member of Sona's peerage muttered, wiping sweat from their brow.

"Ugh… this heat…" another gasped, fanning themselves desperately.

One onlooker, drenched in sweat, shuddered. "It feels like the sun itself is bearing down on us…"

Serafall's eyes narrowed. "This power… It feels… like a Sun God's radiance. Could Shin-kun be a Demi-God?"

Michael's expression darkened. "This aura… It's divine. Almost like ours—but at the same time, different."

From the shadows of the battlefield, Black Flash smirked, his golden eyes glinting with excitement. "Sunlight… in the darkness?" he mused, his voice laced with amusement.

Sirzechs, still watching the sky, felt a rare sense of awe. "This… shouldn't be possible."

But Satria didn't stop there. He raised his hand higher, and the sky itself brightened further.

With a single motion, he swung his arm down—and a colossal gust of searing wind tore across the battlefield, barreling toward Black Flash.

But the dark warrior merely lifted a hand and deflected it with ease.

"Is that all you've got?" Black Flash taunted, stepping forward, his form a blur of black lightning.

BOOM!

In an instant, Satria vanished—closing the distance faster than even the eye could follow.

A blade emerged from his outstretched hand, forged entirely from pure solar energy.

"Blade of Judgment."

With divine force, he slashed downward.

CLANG!!!

Black Flash barely managed to evade, but the sheer power of the attack tore through the ground, sending shockwaves rippling across the battlefield. The air cracked from the sheer force of it.

Recovering, Black Flash retaliated—hurling a swirling torrent of black flames toward Satria.

But Satria clone merely raised his hand, his radiant energy flaring. The flames were instantly dispersed—erased by the sheer intensity of his light.

The battlefield trembled as both warriors clashed—one of darkness, one of light.

Satria's Divine Blade struck with relentless precision, meeting Black Flash's attacks blow for blow. Sparks erupted with each impact, illuminating the night like a meteor shower. The sheer force of their battle shook the entire city.

Every warrior, every leader—everyone—watched in stunned silence.

Serafall's eyes gleamed with fascination as she observed Satria in battle. "Strong and gorgeous," she murmured to herself, captivated by his sheer power. The young man before her wasn't just talented—he was exceptional, a prodigy whose grace and efficiency set him apart.

"Every move he makes is calculated, refined," Michael mused, equally impressed. "He's no ordinary teenager."

Sirzechs, however, felt a different emotion—wariness. He studied Satria with a critical gaze. "If Shin is this powerful… what about their leader, Kazuma? The man hadn't moved at all. He simply stood there, calm and composed. That kind of restraint is even more dangerous."

But Kazuma, overwhelmed by the display of power before him, suddenly stiffened. His eyes widened, knees buckled—and without a word, he collapsed. His body hit the ground with a soft thud, his eyes still open in shock.

Before anyone could react further, Black Flash turned to his opponent with a smirk. "Not bad. You're stronger than I expected."

"And you are a dead man! Searing Chains!"

Satria's clone unleashed fiery bolas that streaked through the air like blazing meteors. They wrapped around Black Flash, burning and constricting, immobilizing him in an instant.

"Now, KILL HIM!"

That was the signal.

The leaders of the Biblical factions moved as one, their combined might converging into an unstoppable force.

Michael soared into the sky, his wings glowing with divine radiance. Raising his hand, he summoned a holy spear crackling with celestial energy. The sheer purity of its light banished the surrounding darkness as he hurled it forward. The spear ripped through the air, a streak of golden fire heading straight for its target.

Serafall Leviathan twirled her hand playfully, but her magic was anything but whimsical. An enchanting, icy mist swirled around her, condensing into glistening snowflakes. With a swift incantation, she unleashed them in a devastating ice storm, razor-sharp icicles forming in an instant before launching forward with unerring precision.

Sirzechs Lucifer stood firm, his presence alone radiating authority. He raised his hand, a swirling mass of dark crimson energy forming at his palm. The air around him crackled with raw power, the sheer force making the ground tremble. With a single, commanding motion, he unleashed the Power of Destruction, a wave of annihilation cascading toward Black Flash.

"Spear of Heaven!"

"Celsius Cross Triggers!"

"Ruin the Extinct!"

The attacks converged. Michael's divine light pierced through the darkness, Serafall's magic froze the very air, and Sirzechs' demonic energy erased everything in its path. The battlefield trembled as the combined force struck Black Flash dead-on.

The impact was cataclysmic.

A blinding explosion consumed the area, sending shockwaves in all directions. The sheer magnitude of the attack shattered the very fabric of space, the night sky illuminated as if dawn had arrived early.

As the dust settled, nothing remained. No sign of Black Flash. No remnants. Nothing but silence.

"Incredible…" Satria's clone exhaled, surveying the aftermath. He nodded, pride gleaming in his eyes. "This victory belongs to all of us. You all did a fantastic job."

Serafall grinned, her usual bubbly energy returning. She latched onto Satria's arm, pressing against him playfully. "And now we know that no matter how bad things get, we can always count on each other." She leaned closer, whispering into his ear, her voice teasing yet earnest.

"Hey, how about we celebrate later? Just the two of us… I want to know more about you, Shin-kun. Do you feel the same?"

"What?!"

Satria's face turned white. He glanced around nervously, afraid one of his wives would catch him in the act.

Michael, oblivious to the teasing, nodded in agreement. "Indeed. This alliance has made our world safer. We should continue to nurture it."

But then—

Sirzechs froze. His eyes widened in disbelief.

"...Postpone your celebrations." His voice turned grim. His hands clenched. "It's… not over yet."

A low, menacing chuckle echoed through the battlefield.

The impossible was happening.

Before their very eyes, Black Flash's body began to regenerate. The darkness that had been obliterated coalesced, reshaping, reforming.

"You think…" A distorted voice growled. "That this is enough to stop me?"

A malevolent aura erupted, thick with rage and raw power. The air grew heavy, as if the very atmosphere rejected his existence.

Black Flash's eyes snapped open, burning with fury. His body pulsed with unfathomable darkness, stronger than before.

"Now…" He sneered, his voice reverberating through the battlefield.

"It's my turn."

The leaders exchanged worried glances. Even together, they had barely contained him. And now—

From the depths of the abyss, two new presences stirred.

'Goldy. Fatalis. It's time.'

A chilling laugh echoed in response.

"Finally…"

A second, robotic voice followed.

{Affirmative}

A low, ominous hum filled the air.

Black Flash stood tall, his dark armor pulsating with a menacing crimson glow. The very air around him seemed to tremble as his Contract Monster, Dragblacker, let out a thunderous roar. The beast's form writhed, shifting as if undergoing an unnatural evolution.

With deliberate precision, Black Flash slid the Survive Card into his Ultimate Legend Driver.

The device crackled with energy before announcing in a mechanical voice:

{Chemy Card: Survive}

A sudden explosion of power erupted from his body. His transformation had begun.

Dark energy coiled around him, his armor morphing, growing more intricate—its once simple design now adorned with dragon motifs and golden ornaments that pulsed with eerie, malevolent light. His presence alone was suffocating, a force that bent the battlefield to his will.

Power unlike anything they had ever felt surged through him. It was intoxicating.

His senses sharpened. His strength multiplied tenfold.

Black Flash clenched his fists, feeling the raw, unrestrained might coursing through his veins. A wicked smirk played on his lips.

He was unstoppable.

The watching warriors could feel it, the undeniable shift in power.

Serafall's usual playful demeanor vanished as a chill ran down her spine. "That's... not normal."

Michael narrowed his eyes. "Could that be his Longinus?" His voice was laced with concern. "But... I don't recall any Longinus possessing such corrupt energy."

Sirzechs' expression darkened, his fists tightening. "This power...!" He took a step back, his usual confidence wavering. "He's even darker and stronger than before… this is dangerous."

Amidst their reactions, Black Flash merely chuckled.

His eyes gleamed with challenges.

"Let's settle this... once and for all."

To be continued...
