Silver-gold flames and endless darkness divided the Grand Imperial Arena into two completely different worlds.

One side blazed with radiant spiritual fire that illuminated shattered stone, fractured pillars, and burning scars spread across the battlefield like molten rivers of light. The Sovereign Soulfire Domain surged endlessly beneath Aether’s control, waves of silver-gold flame rolling across the terrain with majestic authority. Every spark carried warmth, purification, and overwhelming spiritual resonance, as though the battlefield itself had become a sacred furnace capable of cleansing corruption from existence.

The other side drowned beneath suffocating twilight.

Kael’s Endless Eclipse spread across the arena like a living abyss, swallowing light, sound, and spiritual flow beneath layers of oppressive darkness. The sky overhead churned violently as black clouds spiraled through the heavens, consuming even the natural sunlight above the capital. Shadows moved unnaturally throughout the arena floor, twisting like serpents beneath fractured stone while spatial distortions flickered endlessly through the darkness.

Neither domain yielded.

Neither side retreated.

And standing between those collapsing worlds—

Aether and Kael stared at one another in absolute silence.

The pressure radiating from both sides had already surpassed what anyone expected from academy students. Even the reinforced imperial barriers surrounding the arena trembled continuously beneath the collisions between sovereign-level energies.

BOOOOOOOOM!

Another violent impact exploded between the two domains.

Silver-gold soulfire surged upward in towering waves while endless eclipse darkness crashed against it from the opposite side. The resulting shockwave tore across the battlefield with enough force to shatter already-damaged terrain into dust. Cracks spread farther along the arena floor as enormous slabs of black stone rose into the air before being vaporized by colliding spiritual pressure.

The crowd gasped collectively.

Some weaker spectators nearly lost balance despite the barriers protecting them.

High above the battlefield, the sky itself had begun distorting.

Silver currents flowed upward like auroras stretching through storm clouds, while eclipse shadows devoured portions of the heavens with terrifying hunger. The atmosphere around the arena no longer resembled ordinary weather. It resembled the collision of two evolving worlds attempting to overwrite one another.

"This is insane..."

An elder from the western noble section stared downward with visible disbelief.

"They’re still increasing output?"

Another instructor beside him swallowed heavily.

"At this rate... the arena barriers won’t survive much longer."

Meanwhile, standing within the endless darkness, Kael no longer resembled an ordinary human tamer.

The synchronization with the Duskwalker Beast had transformed him completely.

Living shadows covered portions of his body like ancient armor forged from condensed eclipse energy. One side of his face remained calm and human, but his right eye had become entirely black, devoid of any visible pupil or light. Darkness flowed continuously around him like smoke leaking from reality itself.

Every movement he made distorted nearby spiritual energy naturally.

Even standing still—

He radiated dangerous pressure.

The Duskwalker Beast’s influence had partially merged into his existence.

Not a temporary enhancement.

Not simple synchronization.

Integration.

Aether’s golden eyes narrowed slightly.

The Heaven Eye rotated rapidly beneath his pupils, sending countless golden calculation threads spreading throughout the battlefield. Those threads analyzed terrain changes, energy fluctuations, domain pressure, and every movement Kael made.

Yet for the first time since activating the Heaven Eye—

Several future branches remained unreadable.

Not unstable.

Unreadable.

Aether could feel it immediately.

Kael’s synchronization had crossed into territory beyond conventional battlefield prediction.

"He’s becoming part sovereign..." Aether realized silently.

Not fully.

But close enough to distort the battlefield itself.

Across the shattered arena, Kael finally spoke.

"You adapted faster than I expected."

His voice echoed quietly through the darkness, calm and steady despite the overwhelming destruction surrounding them.

Darkness swirled around him slowly as he continued walking forward through the eclipse domain.

"But incomplete harmony cannot surpass true eclipse authority."

The shadows beneath his feet spread outward.

Then—

Ancient black symbols began appearing across the battlefield.

The Heaven Eye reacted violently.

Golden warning threads exploded throughout Aether’s vision.

Danger.

Extreme danger.

The black symbols pulsed one after another beneath shattered terrain like living hearts awakening from beneath the earth. They spread rapidly through the darkness, connecting into enormous geometric formations hidden beneath the battlefield.

Aether’s expression sharpened instantly.

"That formation..."

The moment the symbols connected—

The entire arena darkened.

Not visually.

Conceptually.

The crowd erupted in alarm immediately.

"What’s happening?!"

"The light disappeared!"

"I can’t sense spiritual energy properly anymore!"

Several spectators stood up in panic while academy instructors activated defensive formations around the upper viewing sections instinctively.

Even the imperial elders watching from above frowned seriously now.

Because they recognized the technique.

One old imperial instructor suddenly widened his eyes in disbelief.

"That formation..."

His voice trembled slightly.

"No... he actually learned it?"

Another elder beside him spoke grimly.

"Eclipse Monarch Academy sealed that art decades ago."

"Using it risks permanent spiritual collapse."

"It was never meant for students."

Yet Kael activated it anyway.

BOOOOOOOOOOM!

Dark eclipse energy erupted upward violently.

The arena shook so hard that several outer barrier formations cracked audibly.

The black symbols spread across the battlefield like infection, devouring remaining traces of ordinary spiritual flow. Then something even more horrifying happened.

The shadows swallowed sound itself.

Silence descended unnaturally across the arena.

No wind.

No explosions.

No distant screams from spectators.

Only oppressive stillness remained.

Kael slowly raised one hand.

"Eternal Eclipse."

The moment those words left his mouth—

The battlefield lost all color.

Silver-gold soulfire dimmed slightly.

Dream-space weakened.

Even spiritual perception became distorted.

The world itself felt submerged beneath endless twilight.

Aether immediately felt the change.

The Sovereign Soulfire Domain trembled violently.

Its flames still resisted, still burned proudly against the darkness, but the eclipse pressure multiplied continuously. The Eternal Eclipse did not merely suppress energy.

It suppressed existence itself.

Anything caught inside the formation gradually lost presence within the battlefield.

Movement became uncertain.

Spiritual flow slowed.

Even thought itself felt heavier.

The Heaven Eye flickered.

Golden analysis threads destabilized rapidly.

The calculations attempted recalculation repeatedly, but countless battlefield possibilities vanished before completion.

Aether’s gaze hardened.

"This technique..."

"...it destroys battlefield probability."

It wasn’t simply controlling outcomes.

It erased them.

Across the arena, Kael stepped forward once more.

For the first time since the Sovereign Soulfire Domain awakened—

He advanced confidently again.

The synchronized darkness around him deepened further as the Duskwalker Beast’s distorted silhouette expanded behind him like an enormous abyssal phantom.

"This," Kael said quietly, "is why Eclipse Monarch stands above ordinary academies."

Dark pressure exploded outward.

"Absolute battlefield denial."

The eclipse domain surged violently.

Entire sections of the Sovereign Soulfire Domain were forced backward beneath the pressure. Silver-gold flames flickered as the Eternal Eclipse consumed spiritual flow itself.

Then—

Silver butterflies suddenly erupted throughout the battlefield.

BOOOOOOM!

Dream-space exploded outward around Aether’s position.

The Moondream Hare’s silver eyes shone brilliantly once more despite exhaustion. Dreamlike mist spiraled across the battlefield while countless shimmering butterflies drifted through the collapsing darkness.

Liora stepped beside Aether calmly.

Sweat covered portions of her forehead.

Her breathing remained uneven from earlier strain.

Yet her silver eyes stayed steady.

"You’re not handling this alone."

The dream-field expanded immediately into the Sovereign Soulfire Domain.

At first, the energies should have clashed.

Instead—

They synchronized naturally.

Soft silver dream currents merged into the silver-gold soulfire beautifully, stabilizing portions of the battlefield instantly. Mental suppression weakened while illusion pathways strengthened throughout allied territory.

The Spirit Fairy floated upward with glowing eyes.

Tiny silver particles spread from her body continuously.

Then something unexpected happened.

The dream-space itself synchronized with the soulfire domain.

Liora’s eyes widened slightly.

"Our energies are synchronizing?"

Aether understood immediately.

The Sovereign Soulfire Domain amplified allied spiritual compatibility.

Not just his beasts.

Everyone connected to him.

Suddenly, a massive roar exploded across the battlefield.

BOOOOOOOOOOM!

Titancrest Fangbear slammed both enormous claws into the shattered arena floor violently.

Rock pillars erupted upward across eclipse territory like rising mountains. Fractured terrain shattered beneath the gigantic beast’s raw physical force as Valen forced himself upright once more despite blood still running down his arm.

He grinned fiercely toward Aether. 𝒻𝓇𝑒𝘦𝘸𝑒𝒷𝓃ℴ𝑣𝘦𝑙.𝒸ℴ𝘮

"If the captain’s evolving again..."

"...then I’m not staying down either."

Titancrest Fangbear roared thunderously beside him before charging directly into eclipse territory once more.

This time—

The suppression slowed him far less.

Silver-gold soulfire currents surrounded his body continuously, purifying portions of the eclipse pressure before it fully settled onto him.

The battlefield rhythm changed immediately.

For the first time in the tournament—

Skygate Academy moved as a fully synchronized battlefield unit.

Soulfire stabilized dream-space.

Dream-space enhanced battlefield awareness.

Titancrest Fangbear controlled frontline disruption.

Meanwhile—

The Flame Sovereign Pup dominated the battlefield center aggressively with overwhelming sovereign pressure.

Their coordination evolved in real time.

Kael noticed instantly.

Gray-black eyes narrowed slightly.

"...Interesting."

His Eternal Eclipse still dominated the battlefield overall.

But Skygate’s synchronization had become drastically harder to suppress.

Aether slowly extended one hand forward.

The Sovereign Soulfire Domain reacted immediately.

Silver-gold flames gathered around him like flowing rivers of living spiritual fire. The domain no longer felt external.

It moved with him naturally.

Every gesture controlled battlefield energy directly.

True domain synchronization.

Aether stepped forward once.

BOOOOOOOOOOM!

Entire sections of soulfire erupted beneath Kael instantly.

Silver-gold pillars exploded upward from hidden ignition points throughout eclipse territory. The synchronized Kael vanished into shadows immediately—

Yet the flames followed him.

Like living spiritual judgment.

Darkness erupted behind Aether suddenly.

A gigantic eclipse claw descended from the sky violently.

The attack distorted space itself as it tore downward toward him.

But before impact—

Silver dream butterflies intercepted first.

BOOOOOOM!

The claw slowed briefly inside the dream-field.

Long enough.

Aether’s soulfire exploded upward immediately afterward.

The gigantic eclipse claw shattered into darkness.

The crowd erupted.

"They’re coordinating perfectly now!"

"Skygate adapted AGAIN?!"

"How are students fighting at this level?!"

Even academy leaders watching from above had fallen completely silent.

Because this battle no longer resembled a tournament.

It resembled sovereign warfare.

Deep beneath the arena, hidden within ancient chambers concealed beneath the capital—

Silver instruments suddenly began ringing violently.

One hunter’s face paled instantly.

"Outside interference detected!"

Seraphel turned sharply.

"What?"

Another hunter activated several formation screens rapidly.

"There’s a foreign spatial signal entering the capital!"

The hidden chamber froze.

Because the signal originated from outside the empire entirely.

Seraphel’s gray eye narrowed dangerously.

"They came early..."

Emergency formations throughout the underground network intensified instantly. Ancient silver restraints activated one after another beneath the city while hidden hunters prepared weapons rapidly.

Because hidden-world organizations were never supposed to interfere openly during the National Championship.

Yet now—

Something was approaching anyway.

Back inside the arena, the battlefield destabilized further.

The collision between eclipse and soulfire intensified continuously.

Barrier formations groaned harder with every passing second.

Cracks spread visibly across several protective pillars surrounding the arena.

And deep within Aether’s shadow—

The Fallen Succubus slowly opened her crimson eyes fully.

Inside the sealed spiritual space, countless crimson chains surrounded her elegant figure.

Yet those chains had begun cracking.

Tiny fractures spread slowly across the restraints surrounding her existence.

The Sovereign Soulfire Domain had stabilized Aether’s soul.

But simultaneously—

The overwhelming synchronization pressure had weakened deeper seals unintentionally.

The Succubus smiled faintly.

"How unexpected..."

Her crimson eyes reflected the battlefield outside.

Kael’s eclipse darkness.

The silver-gold soulfire.

The evolving domains colliding endlessly.

"A battle between incomplete sovereigns..."

"...how nostalgic."

Outside—

BOOOOOOOOM!

Another massive collision erupted between domains.

The impact shook Aether’s spiritual sea violently.

Several crimson chains cracked further instantly.

The Heaven Eye reacted immediately.

Danger warnings surged across Aether’s vision again.

This time—

Not from Kael.

From within.

Aether’s expression changed slightly.

Because he could feel it now.

The seal was destabilizing.

Dark seductive energy leaked faintly into his consciousness once more.

Not aggressive.

Not violent.

Patient.

Watching.

Across the battlefield, Kael suddenly slowed.

His distorted gaze locked directly onto Aether.

"...There it is again."

The same abnormal presence he sensed earlier.

But now—

Far clearer.

Behind him, the Duskwalker Beast released a low distorted growl.

Not hostility.

Caution.

Even the abyss-corrupted sovereign instinctively recognized the dangerous entity sealed inside Aether.

The battlefield escalated again.

Silver-gold flames surged violently across half the arena.

Eternal Eclipse consumed the other half endlessly.

Dream butterflies drifted through collapsing domains like fragments of starlight.

Titancrest Fangbear roared while charging through shattered terrain.

The Abyss Raven screeched overhead as dark feathers rained from the sky.

And above everything—

The heavens themselves had begun cracking faintly beneath the overwhelming pressure.

The finals were no longer contained.

Something greater was approaching.

And everyone could feel it.

At the center of the Sovereign Soulfire Domain, Aether stood silently while silver-gold flames flowed around him continuously.

But deep within his shadow—

Crimson eyes watched patiently through cracking chains.

Meanwhile—

Far beyond the empire’s borders—

Something ancient had already begun moving toward the capital.
