"Deployment successful, sir. Stand by for your next objective."
JARVIS' voice resonated calmly within the helmet, layered seamlessly over Yuuki's neural interface. Data streamed across his HUD—thermal signatures, hostile markers, structural decay—all processed in real time.
Encased within his custom-built armor, Yukihira Yuuki stood at the center of the battlefield like a singularity of control.
Unlike the standardized GDI combat systems, this suit was his own creation—engineered, refined, and perfected through his personal understanding of both warfare and advanced technology. The Mark XLVII gleamed under the dim, ash-filled sky, its design echoing the older Mark XLVI frame but with a sharper, more evolved profile. Silver plating dominated the abdomen and extended down toward the thighs, blending seamlessly with crimson and gold segments that reinforced key combat zones.
At its core—
A reactor burned steadily.
Alive.
"JARVIS," Yuuki muttered, flexing his fingers slightly as servos responded with precise synchronization, "remind me not to do atmospheric drop deployments for a while."
His neck rolled slightly as he adjusted, reacquainting himself with the suit's weight distribution. It had been some time since he'd used this model—nanotech systems had long since replaced the need for older exo-frames. Still…
There was something nostalgic about it.
"You requested drop pod insertion, sir," JARVIS replied evenly.
Yuuki smirked faintly behind the mask.
"…It's thrilling."
"We could have utilized the Chronosphere. The Mark XLVII and Iron Legion units are fully compatible with spatial displacement protocols."
The Chronosphere stood as one of humanity's most revolutionary—and dangerous—technological breakthroughs. Originally developed by the Allied forces during the Second World War, it was designed as a mass teleportation device capable of displacing entire units across space in an instant. Its early iterations were unstable, experimental, and feared as much as they were admired, yet they proved decisive in altering the course of global conflict.
Under the theoretical foundation laid by Albert Einstein, the Chronosphere evolved far beyond its original purpose. By the time of the Third World War, its improved versions had become precise, reliable instruments of warfare—capable of repositioning armies, deploying strikes behind enemy lines, and collapsing strategic defenses without warning. Its influence extended even further, playing a critical role during the Psychic Dominator Disaster and later the Mental Omega War on Earth 1.0, where control of space itself became as vital as control of land or air.
In its modernized form, the Chronosphere no longer functioned merely as a large-scale displacement engine. It had been refined into a highly controlled spatial manipulation system, capable of teleporting selected units within a defined operational radius with near-instantaneous execution. This advancement allowed for tactical deployments—rapid insertions, emergency extractions, and synchronized battlefield maneuvers—without the catastrophic instability of earlier models.
For Yuuki and the GDI, the Chronosphere was no longer just a weapon.
It was a tool of absolute positioning—
The ability to decide where a battle is fought… before it even begins.
Yuuki exhaled lightly.
"The Chronosphere is reserved for strategic deployment," he said. "I designed it that way." His gaze flicked across the battlefield, briefly noting the Siren formations tightening ahead. "And we'll need it later—for the big guns."
A faint pause.
"You know how long those take to charge."
"Just in case you forgot, sir."
"…I didn't."
His eyes narrowed slightly as the HUD finalized environmental analysis.
Earth designation: 3.0 variant.
Atmosphere: stable.
Hostiles: confirmed.
Unknown entities: categorized.
Yuuki tilted his head slightly, observing the Sirens—particularly the one at the front, her tendrils shifting with unsettling fluidity.
"…Not a bad world," he murmured.
Then, dryly—
"…except for the tentacle girls."
A brief pause.
"…Makes you wonder if those old doujin theories had some truth after all."
Behind him, ten Iron Legion units stood motionless—silent, ready, waiting for command.
In front of him—
An entire Siren force.
And between them—
A question that had yet to be answered.
Yuuki took a single step forward.
The ground cracked softly beneath his armored weight.
Now—
The real introduction would begin.
Purifier's patience snapped.
Being ignored was not something she tolerated—especially not on a battlefield she already owned.
Her expression darkened as she raised her cannons, energy beginning to gather at their tips. This time, when she spoke, her voice carried weight—authority sharpened into a threat.
"You," she said coldly, locking her gaze onto the red-and-silver figure. "Who are you? The humans of this world do not possess this level of technology."
Yuuki tilted his head slightly inside the helmet.
English.
So the linguistic structure aligned.
Good—no need to waste time decoding an entirely new language system. That alone told him this wasn't a completely foreign civilization—just a divergent one.
He rolled his shoulders once, then casually folded his arms.
"What," he said dryly, "never heard of Iron Man?"
The voice that came from the armor was unmistakably male.
And that alone—
Made the Sirens pause.
Men were rare. Almost nonexistent in direct combat roles in this world. And yet here stood one—calm, composed, wrapped in technology that didn't exist in their records.
Purifier's irritation shifted.
Into interest.
A slow, unsettling smile crept across her face.
"Iron Man…?" she echoed, tasting the words. "Interesting." Her eyes gleamed. "A human… daring to oppose a Siren."
Yuuki raised an eyebrow behind the mask.
"Sirens?" he repeated. "That's what you girls are called?"
A few of the surrounding Sirens exchanged brief glances.
"…Is this one defective?" one muttered.
Purifier let out a soft, mocking laugh.
"You wear armor… and you stand against us?" she said, almost amused now. "Power armor has already been tested by your kind. It failed." Her tendrils shifted lazily behind her. "We've ruled this world's oceans for ten years. Sirens are common knowledge."
Her smile sharpened.
"And yet… you've never heard of us?"
Yuuki shrugged slightly.
"Nope."
A beat.
Then, casually—
"If it helps, I'm Iron Man." A faint pause. "Well… sort of."
Behind him, the Iron Legion units remained motionless, their glowing cores steady—silent witnesses to the exchange.
"I've never fought a Siren before," Yuuki continued. "But I have dealt with other tentacle-type problems." His tone carried a hint of dry amusement. "Worked out pretty well."
Inside the armor, his eyes flicked across combat readouts.
Unknown enemy classification.
Adaptive.
Technological-organic hybrid.
Interesting.
Because from his perspective—
This wasn't anything new.
He had fought rogue AIs that could rewrite battlefields in real time. Simulated entire world wars for strategic optimization. Faced the Brotherhood of Nod with their advanced laser weaponry and asymmetric tactics. Engaged extraterrestrial threats that operated beyond conventional physics.
Compared to that—
These Sirens?
Unknown.
Yes.
But not intimidating.
Not yet.
His current suit—the Mark XLVII, once dubbed the Ultimate Armor before nanotechnology rendered it obsolete—hummed quietly as systems aligned, power routing efficiently through every joint and weapon system.
Purifier, meanwhile, stared at him—curiosity now fully awakened.
Because for the first time in a long while—
She wasn't looking at prey.
She was looking at something… new.
"Hooo… perhaps we should capture you," Purifier said, her smile curling with predatory interest. "That device you used to arrive… it's very interesting."
Yuuki didn't react. He simply raised his right arm, palm facing forward, the repulsor at its center glowing faintly as it charged. His stance remained relaxed—almost casual—like a man testing a theory rather than preparing for battle.
"Then why don't you try taking a hit from this human technology?" he replied evenly. "I'm sure you can, right? You're a Siren after all."
A brief silence followed.
Then Purifier laughed.
"A human… challenging a Siren?" Her eyes gleamed with mockery. "Don't make me laugh."
Her rigging shifted instantly. Massive cannons aligned with mechanical precision, energy condensing into a single, focused point. The air around her distorted under the pressure as she fired without hesitation.
The shot tore forward like compressed annihilation.
It struck Yuuki directly in the chest.
The explosion consumed him in an instant—fire erupting outward, shockwaves cracking the ground beneath his feet. Dust and debris surged violently, obscuring everything within the blast radius.
For a moment, there was nothing.
Purifier exhaled, already turning away. "Hmph… humans. Stupid…"
But then—
Her visor flickered.
Something was wrong.
"…What?"
The smoke began to thin.
And there—
Still standing.
Yuuki.
Exactly where he had been.
Unmoved.
Untouched.
Not a single dent marred the surface of his armor. No scorch marks. No sign of damage. Even the Iron Legion behind him stood perfectly intact, their golden masks gleaming faintly through the fading haze.
Silence spread across the battlefield.
Even the Sirens hesitated.
Purifier's expression faltered for the first time.
"How…?" she whispered, the word slipping out before she could contain it.
Behind her, Yorktown and Laffey stared in stunned disbelief. They had witnessed Siren firepower countless times—seen entire fleets erased, bases reduced to ash.
And yet—
This man had taken it head-on.
And survived.
Inside the armor, Yuuki blinked once as diagnostic data scrolled across his vision. Impact force analyzed. Energy dispersal confirmed. Structural integrity—unchanged.
Then he looked up.
"…Holy hell."
His voice carried something unexpected.
Not arrogance.
Not defiance.
Genuine curiosity.
"That was a 420 mm round, wasn't it?" he said, tilting his head slightly as he took a step forward. "How did you compress something like that into a shot that size?"
He studied her rigging, eyes narrowing behind the mask as if analyzing a prototype.
"Miniaturized naval artillery with that kind of output…" he continued, almost to himself. "And rapid deployment too?" A brief pause. "…That's actually impressive."
Purifier didn't answer.
Because for the first time since the battle began—
She wasn't looking at prey.
She was looking at something that had just taken her strongest attack…
And responded by admiring the engineering behind it.
As Yuuki continued his outward commentary, his tone shifting into that of a fascinated engineer, a quieter channel opened within his helmet—one only JARVIS could hear.
"Is that it?" he murmured internally. "Just 0.5% damage? With auto-repair, that's basically zero."
[Confirmed, sir. Structural integrity remains optimal. Regeneration cycle complete.]
It barely registered.
Years ago, his earlier suits had struggled against heavy weaponry—especially during engagements with Nod forces, whose arsenal pushed beyond conventional limits. He remembered those fights well—armor nearly breached, systems failing under pressure.
So he adapted.
Improved.
Evolved.
From Mark 43 onward, his suits were no longer just combat gear—they were fortified systems capable of enduring missile saturation, radiation fallout, and direct naval bombardment. By the time he reached the Mark XLVII, layered upgrades and redundancies had rendered most conventional weaponry… irrelevant.
And this?
A compressed 420 mm naval round?
Impressive engineering.
But outdated in destructive capability.
Outside, Purifier stared at him, disbelief cracking through her composure.
"You… HOW?!"
Yuuki rolled his shoulder slightly, as if testing his own durability.
"…Guess I'm tougher than I thought," he said lightly. Then his tone shifted. "My turn, right?"
Purifier hesitated—but only for a fraction of a second.
"…Very well," she said, forcing her confidence back into place. "Take your shot."
Yuuki didn't rush.
He raised his arm slowly, palm facing forward as energy began to gather. A sharp, rising whine filled the air—the repulsor charging far beyond standard output.
"Alright then…" he said.
"Here goes."
SHOOO—!!
The beam fired without warning.
A concentrated lance of light tore across the battlefield and struck Purifier directly in the chest.
There was no explosion.
No resistance.
Just—
Impact.
And then—
She was gone.
Launched backward like a ragdoll, her body tearing through the air and vanishing into the distant horizon, hurled kilometers away in an instant.
Silence.
Then chaos.
The surrounding Sirens froze—processing what they had just witnessed.
Yuuki didn't give them time.
"Legion—engage."
Behind him, the ten Iron Legion units moved as one.
Repulsors ignited.
Beams of light erupted across the battlefield, each shot precise, controlled, devastating. One by one, the Sirens were struck—sent flying in all directions, their formations shattered instantly under the overwhelming counterforce.
Yorktown and Laffey could only stare.
Moments ago, these enemies had been untouchable.
Unstoppable.
And now—
They were being thrown aside like nothing.
"JARVIS," Yuuki said calmly, already shifting targets, "lock onto aerial units. Drones—disable with extreme prejudice."
[Yes, sir.]
The Iron Legion responded immediately.
Shoulder ports opened.
Arm-mounted launchers deployed.
A storm of micro-missiles erupted skyward.
In seconds—
The sky was cleared.
Every drone—gone.
Explosions rippled overhead like distant thunder, fragments raining harmlessly into the ocean beyond.
The battlefield shifted.
For the first time—
The Sirens were on the defensive.
Yuuki descended from a short hover, landing smoothly in front of Yorktown and Laffey. His repulsor fired once more, eliminating a straggling drone before it could regroup.
The glow faded.
Smoke drifted.
And then—
He turned.
Servos whirred softly as the armored figure faced them, each movement accompanied by the quiet, mechanical precision of something far beyond anything they had ever seen.
Yorktown instinctively tightened her hold on Laffey.
Both of them were trembling.
Not from fear of him—
But from everything that had just happened.
The man of iron stood before them.
Silent.
Unfamiliar.
And impossibly powerful.
"You girls okay?"
Silence answered him.
Yorktown held Laffey tightly, her body still trembling, her mind struggling to catch up with everything that had just happened. Laffey clung to her, wide-eyed and speechless, her small frame shaking.
Yuuki didn't wait.
"Sorry—no time for introductions," he said quickly. "JARVIS, deploy a force shield around them."
From his thigh compartment, he pulled out a compact metallic sphere no larger than his palm. With a single press, the device activated—unfolding mid-air into a lattice of energy that expanded outward in an instant.
A blue dome snapped into existence around them.
Smooth.
Seamless.
Impenetrable.
Yorktown's breath caught as the barrier formed, enclosing both her, Laffey—and the armored man himself.
Before either of them could react, Yuuki turned slightly.
"You two stay here," he said firmly. "We'll handle the Sirens."
And then—
He stepped forward.
His body phased through the barrier like a ghost passing through mist.
Gone.
Yorktown's eyes widened.
Instinctively, she reached out—her hand pressing against the inside of the shield.
It didn't yield.
It didn't ripple.
It felt like solid glass.
"Big sister Yorktown…" Laffey's voice trembled as she touched it too, pressing harder, then striking it weakly. "We're trapped in this… this shield… What's going to happen to us?"
Yorktown remained still for a moment, her hand resting against the barrier as she stared outward.
At him.
"…I don't know," she admitted softly.
A pause.
Then, quieter—
"But… let's trust him."
Laffey looked up at her, confused. "You trust this man?"
Yorktown's grip around her tightened slightly.
"He could've killed us already," she said. "Easily."
Her gaze didn't leave the battlefield.
"But he didn't."
Another pause.
"…So for now—we survive."
Laffey hesitated.
Then slowly nodded.
Together, they turned their attention outward.
Just in time to see it.
The Iron Man ignited.
Brilliant bursts of light erupted from his back, hands, and feet as thrusters roared to life, lifting him effortlessly into the air. The motion was smooth—controlled—like gravity itself had lost its hold on him.
Around him, the ten white-and-black armored units followed.
Perfect synchronization.
Perfect formation.
They rose into the sky as one.
Yorktown's eyes widened.
"…They can fly…"
It wasn't just him.
Every single one of them.
For beings who had spent their entire existence bound to the sea—
Watching something dominate the sky so completely…
Felt unreal.
Above the burning remains of their home—
A new force had entered the battlefield.
And for the first time in a long, long while—
The Sirens were no longer in control.
======================
Yuuki soared upward, thrusters roaring as he cut through the smoke-filled sky. Below him, the battlefield burned—but up here, everything was clarity and control. Flight was no longer a skill he practiced. It was instinct. Every adjustment in altitude, every shift in direction, every microsecond correction flowed seamlessly through him, as if the armor were not something he wore—but something he was.
The Iron Man suit was never just equipment.
It was identity.
Back in his world, during the height of the Third Tiberium War and the Ascension Conflict, that crimson-and-gold figure descending from the heavens had become more than a weapon of war. It had become a symbol. A promise. Hope, made real in the shape of a man who refused to command from afar.
Yuuki didn't watch battles from orbit.
He entered them.
A High Commander… leading from the front.
Many feared that.
Many questioned it.
But to the soldiers of GDI, it meant only one thing—
They were never alone.
Still, the armor was only part of him. Beneath it lay something far more dangerous—power he chose not to use. The suit grounded him, anchored him to discipline, to strategy, to effort. Every victory earned through precision and intellect—not overwhelming force.
Because once—
This had all been fiction.
A dream born from stories. From comics. From cinema.
Until he made it real.
Through sheer will, relentless intellect, and an unbreakable resolve, Yuuki turned imagination into machinery. Steel into purpose. Concept into legacy.
But that legacy—
Was not born in triumph.
It was forged in captivity.
He remembered that day with perfect clarity.
The day Nod annihilated his entire unit in Sarajevo. Aftermath of the Liquid Tiberium Explosion.
Not a single soldier left standing.
Except him.
Not out of mercy—but necessity.
They knew who he was. The mind behind GDI's rapid technological evolution. The one who had forced Nod into the shadows, who turned the tide of war with innovation alone.
So they took him.
Locked him away.
And forced him to build.
To create.
To advance their weapons.
But Yuuki didn't break.
He adapted.
He deceived.
He played their game better than they ever could.
He asked for materials. Tools. Components. Promised them something greater.
And they gave it to him.
That was their greatest mistake.
Because instead of forging a weapon for Nod—
He forged his escape.
The Mark I.
Crude. Heavy. Imperfect.
But alive.
Built from scraps and salvaged missile systems, it was never meant to last—it was meant to break through. And when the moment came, it did exactly that. Steel walls crumbled. Armed guards fell. The compound burned as Yuuki tore his way out with nothing but raw power and desperation fueling him.
Then he flew.
For the first time.
A violent, unstable ascent powered by makeshift thrusters.
Freedom within reach—
Until the fuel ran out.
And gravity reclaimed him.
He fell from the sky and crashed into the frozen mountains below, the Mark I barely holding together as it absorbed the impact. It should have killed him.
But it didn't.
GDI found him.
Brought him back.
Saved him.
But the suit…
Was left behind.
And in war—
Nothing valuable stays lost for long.
Nod found it.
Recovered it.
Studied it.
Then twisted it.
The Iron Monger was born.
A corrupted reflection of his creation—larger, more brutal, infused with Nod's ruthless engineering. It wasn't just a suit.
It was a challenge.
And Yuuki answered.
By then, he had built the Mark III.
Faster. Smarter. Refined.
But even then…
It wasn't enough to make the fight easy.
The Iron Monger was relentless—raw strength without restraint, power without control. It pushed Yuuki to his limits, forcing him to confront not just an enemy…
But his own legacy turned against him.
That battle nearly broke him.
But in the end—
There was one difference the armor could never replicate.
The man inside it.
And now—
Hovering above a battlefield that didn't belong to his world, facing enemies that defied everything he knew—
That same man returned.
Not as a prisoner.
Not as a survivor.
But as something far more dangerous.
A commander.
A symbol.
A weapon forged in war—
Refined through loss—
And now unleashed upon a world that had never seen anything like him.
After the Iron Monger incident, the wreckage did not remain in enemy hands for long. GDI eventually recovered what was left of the suit, dissecting every component, every system, every fragment of Yuuki's original design. But what they produced from it was not another Iron Man.
It was something else.
Cruder in philosophy.
More controlled.
The Iron Monger platform became a mass-produced war asset—standardized, weaponized, and deployed against Nod in large numbers. It lacked the elegance and adaptability of Yuuki's designs, but it carried brute force in abundance. Where Iron Man was precision, the Iron Monger was pressure. And in war, both had their place.
Yuuki, however, refused to take part in it.
He drew a line.
Despite pressure from the GDI council—despite requests, negotiations, even quiet coercion—he never shared the true Iron Man technology. Not the core systems. Not the architecture. Not the integration between man and machine that made the suit more than just armor.
Because he understood something they didn't.
If GDI could mass-produce it—
So could Nod.
And the moment that happened, the war wouldn't escalate.
It would spiral out of control.
Instead, Yuuki chose a compromise. He poured his expertise into improving GDI's existing Zone Armor, refining it, enhancing its performance, pushing it far beyond its original limits. The soldiers became stronger, faster, more durable.
But never… Iron Man.
That remained his alone.
Even now, after countless upgrades and iterations, after reaching the pinnacle of nanotechnology with suits like the Mark 50 through Mark 85, Yuuki still found himself returning to an older design.
The Mark XLVII.
The Ultimate Armor.
It wasn't the most advanced anymore.
It wasn't the most efficient.
But it was his.
Every plate, every system, every line of code carried history—lessons learned, battles fought, scars remembered. It was a suit built not just for war, but for meaning.
The nanotech armors—the Mark 85 especially—remained on standby. Adaptive, near-limitless in configuration, capable of responding to threats far beyond conventional understanding. If the Sirens proved overwhelming, he could switch instantly.
But as things stood—
That didn't seem necessary.
Hovering above the battlefield, watching Sirens scatter under repulsor fire, Yuuki's systems remained stable. No strain. No escalation required.
The Mark XLVII was enough.
More than enough.
And somewhere beneath that composed exterior—
There was a quiet satisfaction in that.
Because it meant one simple thing.
This new war—
Hadn't forced his hand yet.
===============
Purifier staggered back through the smoke, her body trembling—not from pain alone, but from something far more unfamiliar.
Disbelief.
Her chest—where the repulsor had struck—was… melting.
The once flawless surface of her body, something that had deflected shells, resisted fleets, and endured countless battles, now warped and broke apart under a force she could neither analyze nor understand. Fragments of her form glowed, destabilizing, as if her very structure was rejecting itself.
"That's… impossible…" she muttered, voice cracking.
Then she screamed.
"IMPOSSIBLE! THERE IS NO HUMAN TECHNOLOGY THAT CAN KILL A SIREN!!"
Around her, the other Sirens rose slowly—damaged, scorched, destabilized in the same way. Their movements were less precise now, less certain. For the first time since their arrival on this world…
They looked shaken.
Because the attack wasn't just impact.
It was penetration.
Repulsor energy didn't behave like conventional weapons. It struck as a concentrated beam, then dispersed upon contact—its energy blooming outward through whatever it hit. With sufficient power, it didn't just push or explode.
It erased.
Steel.
Armor.
Anything.
Where Nod had mastered laser weaponry during the Tiberium Wars, GDI had answered with railgun systems—kinetic devastation refined into science. But Yuuki… had gone further.
Repulsor technology wasn't standard.
It was personal.
His.
"Now we do," Yuuki replied calmly.
Purifier's head snapped up, fury burning in her eyes.
"WHO… ARE YOU?!"
Yuuki hovered slightly, stabilizers adjusting as he raised his arm once more, palm glowing brighter than before.
"Well…" he said casually, almost amused.
"I am… Iron Man."
The beam fired again.
A precise, surgical strike.
This time, it didn't push.
It pierced.
A clean line of light tore through Purifier's chest—and for a brief moment, everything seemed to pause.
Then—
Her body split.
A hole burned straight through her core.
Yuuki's eyes narrowed slightly behind the visor—not in shock, but in fascination.
Because what followed wasn't what he expected.
No red.
No organic response.
Instead—
A glowing yellow fluid pulsed faintly from the wound, shimmering unnaturally as it spilled.
"…Yellow blood," he murmured.
His tone shifted—analytical.
"You're not exactly human… are you?"
Purifier's body trembled violently, her systems—or whatever passed for them—struggling to stabilize.
Her gaze locked onto him, filled with rage.
"Damn you!!"
"Legions," Yuuki's voice cut cleanly across the combat channel, calm and absolute, "this one's mine. Neutralize the rest. Keep the bodies intact."
A brief pause—then ten acknowledgments pulsed through the network.
"Those girls upstairs are going to love this," he added under his breath.
Because once this was over, every Siren body would be shipped straight to the Little Doctor for analysis. Dissection. Reverse engineering. If these things could be understood—
They could be weaponized.
"FUCKING HUMAN—DIE ALREADY!!"
Purifier roared, rage overriding whatever composure she had left. Her cannons flared violently as she unleashed a barrage—round after round screaming through the air toward Yuuki.
But to him—
It was slow.
His HUD painted every trajectory in clean predictive arcs. Wind resistance. velocity decay. impact zones.
He moved before the shots even fully left the barrel.
A shift to the left.
A roll upward.
A sharp dive.
He weaved through the bombardment effortlessly, thrusters flaring in controlled bursts as he danced through explosions that never quite reached him.
Around him, the battlefield erupted again.
Other Sirens opened fire on the Iron Legion units, their cannons thundering as anti-air bursts filled the sky. Shells struck—direct hits, multiple impacts—
And did nothing.
The Legion units barely flinched.
Their armor absorbed the kinetic force, redistributed it across layered systems, converting impact into stored energy rather than damage. Explosions rippled harmlessly across their frames, dissipating like rain against stone.
No recoil.
No stagger.
Just… forward motion.
Yuuki dropped from above.
One Siren turned too late.
His fist connected.
The stored kinetic energy discharged instantly.
BOOM—!!
The Siren was launched backward like a missile, her body tearing through the air before slamming into the distant ruins with catastrophic force.
Yorktown gasped.
Laffey's mouth fell open.
They had never seen anything like it.
Not just strength—
But control over impact itself.
Yuuki straightened mid-air, stabilizers adjusting as he recalibrated his position. The more energy he absorbed, the more devastating his counterstrikes became.
Efficient.
Elegant.
Terrifying.
But even as he fought—
His mind was elsewhere.
Analyzing.
Observing.
Those riggings.
His eyes tracked one of the Sirens as she fired again—watching carefully, frame by frame through enhanced perception.
The shells.
They shrunk before firing.
Then expanded back into full-scale naval rounds the moment they exited the barrel.
"…Mass manipulation?" he murmured. "Or dimensional compression?"
It didn't align with conventional physics.
Not even advanced GDI frameworks.
A girl—humanoid—carrying what amounted to a floating naval weapons platform… and firing ammunition that altered scale mid-flight.
It bordered on—
Magic.
Or something close enough to it.
Even after everything he had seen—Scrin biotechnology, Nod's experimental weapons, simulated war systems—
This was different.
Completely different.
Which made it valuable.
Extremely valuable.
Back on Earth 2.0, technological growth had plateaued. Mid-21st century limitations. Incremental improvements, nothing revolutionary.
But this?
This was a breakthrough waiting to be claimed.
He could already imagine it—
The researchers aboard the Little Doctor tearing this apart, studying every mechanism, every anomaly, every impossible principle behind it.
And unlike Scrin tech—
This was understandable.
Adaptable.
Usable.
Yuuki's eyes narrowed slightly as another Siren charged.
"…Yeah," he muttered. "This world just got a whole lot more interesting."
Yorktown and Laffey stood frozen, their eyes wide, their breaths unsteady. For the first time since the war began, the Sirens—those invincible, untouchable beings—were being overwhelmed. Not by fleets. Not by shipgirls. But by a single human.
A human in armor… yet undeniably human.
The battlefield had become something unreal. What once was a place of despair and inevitable defeat had turned into a display of absolute dominance. Beams of light tore through Siren bodies with ruthless precision. Repulsor blasts pierced what had once been thought indestructible. Some Sirens were cut down mid-air by glowing blades, others dragged from the sky and slammed into the ground with overwhelming force.
They had no chance.
No adaptation.
No answer.
Yorktown's lips trembled as a single tear rolled down her cheek. Her arms tightened around Laffey as she stared at the scene unfolding before her, unable to look away.
"…Commander…" she whispered softly, her voice shaking with emotion. "Do you see this…?"
Her gaze remained locked on the man in the sky.
"We finally have a chance to fight back…" she continued, her voice breaking slightly. "After three years… after everyone's sacrifice…"
She swallowed, her chest tightening.
"…someone finally stood up to them."
Laffey clung to her silently, her small hands gripping tightly as if afraid this moment would disappear if she let go. Her wide eyes reflected the same fragile hope—something neither of them had felt in a very long time.
Across the battlefield, Purifier watched in disbelief as her forces fell one after another. The Iron Legion moved like executioners, precise and merciless, dismantling every Siren with terrifying efficiency. Their attacks were not wild or desperate. They were calculated. Controlled.
Even in destruction, there was intent.
The bodies remained intact.
It was not just a battle.
It was collection.
Purifier's teeth clenched as something unfamiliar crept into her mind.
Fear.
For the first time, she turned away from the fight.
She ran.
But she didn't make it far.
A flash of light cut through the air, and a repulsor beam tore through her leg. She collapsed instantly, crashing hard against the scorched ground. Pain surged through her as she tried to regain control, her weapons shifting to fire—
But she froze.
He was already there.
Standing over her.
She looked up—and what she saw made her eyes widen.
The Iron Man's weapon shifted, reforming into something else entirely. Not a cannon. Not a repulsor.
A blade.
A blade of pure light.
Her breath caught.
That was Siren technology.
"How…?" she whispered, her voice trembling with disbelief.
Before she could react, he moved.
One clean strike severed her rigging at its base.
Another strike followed immediately after.
Then another.
Each movement was faster than her perception could keep up with. Her weapons—her pride, her strength—were dismantled piece by piece before she could even issue a command. The floating cannons fell silent, their structure collapsing as they dropped uselessly to the ground.
In seconds—
She was disarmed.
Completely.
The Iron Man stepped forward, his repulsor rising once more, glowing faintly as it pointed directly at her face.
"Not so tough now, are you?"
