Marvel Cybernetic Girl

—Infinite Mental Realm: Space

Number of Deaths: 423

With a deep breath, Kagura opened her eyes once again—back at the starting point.

Nothing had changed.

The infinite silver-white void stretched endlessly before her, the majestic Möbius ring looped beneath her feet, and high above, like an unreachable goddess, stood the blue-clad queen.

"Tch… this is getting ridiculous," Kagura muttered, grimacing.

Against this nearly invincible queen of space, a deep sense of helplessness gnawed at her.

Even after dying over four hundred times, there was no progress.

No breakthrough. No sign of hope.

It felt like she was trapped in some cursed round of Dark Souls—an endless, punishing loop of failure.

Ugh... I've never liked these suffer-fests!

What's wrong with easy hack-and-slash games?! Or fawning over my 2D waifus in peace?!

...

In these 400-plus failed challenges, Kagura had tried nearly everything she could think of.

Lightning-fast evasions, furious blitz attacks.

Long-range bombardments, tricky diversionary strikes.

Even activating her core's Quantum Teleportation skill...

But not a single move had ever touched Nihility.

That queen standing so loftily in the sky—the supreme ruler of space—simply tore the fabric of space itself with cold precision, slicing Kagura apart in an instant... every single time.

Sure, she had infinite retries left. But this wasn't sustainable.

Staring at the serene yet deadly figure who never bothered to attack first, Kagura pondered desperately.

So what the hell do I need to do to fight someone who controls space itself...?

This feels even harder than taking down Hela face-to-face!

"Oh? Are you finally giving up?"

Nihility's voice rang down unexpectedly—the rare sound of the queen speaking on her own.

"In the end... just a mere human. Is this really the extent of your resolve? I find it amusing that the Soul Stone would acknowledge someone like you."

"Still mocking me, are you?" Kagura chuckled bitterly.

"Don't worry. I'm not giving up. Four hundred tries? That's nothing compared to the ten to the forty-third power of attempts this space allows. I've barely begun."

Nihility smirked coldly. "You talk a good game. But no matter how many times you try, your pathetic, brainless attacks will always end the same way."

"You don't seriously think I'd get tired, do you?"

"No, not at all."

Kagura smiled slyly. "I'm just gathering intel. After all, if I don't squeeze some useful information out of you... how will I ever find a way to win?"

"Hah! You really are adorably naïve, Kagura."

Nihility let out a scornful laugh.

"But fine. Think of this as some meaningless entertainment. Let's continue this little farce of yours."

"Just as I'd hoped."

With a sharp clang, Kagura summoned her vibranium blade once more.

"No matter how many times it takes... I will defeat you!"

Even in these four hundred defeats, her mind had never stopped working.

How does one fight against space itself?

The Space Stone represented the highest authority over space in the universe. Since Nihility was its manifestation, her power to manipulate space must be absolute.

Ripping space apart. Folding it. Bending it. Warping it.

If Nihility wanted to, she could've killed Kagura the moment she set foot in this realm—without a word, without a fight.

But this was a trial. Which meant... there had to be a way to overcome it.

And from Nihility's last few words, Kagura had picked up on something important.

Blind attacks were meaningless. No matter how clever, fast, or powerful—they were useless against an opponent who controlled space itself.

And Nihility was right—prolonging the battle, waiting for an opening, dragging it out in hopes of exhausting her opponent... those strategies were pointless, because Nihility could not tire.

She was the Space Stone itself.

Which means...

There was only one possible rule for victory.

To fight space... I need to use space itself.

Kagura slowly closed her eyes, focusing all her senses.

She let herself feel the space around her. Every ripple. Every shift. Every unseen current.

Nihility kept calling her "just a human"... but Kagura was no ordinary human.

She possessed an advanced android body, and her mysterious core reactor—the Unlimited Conceptual Skill System—was capable of far more than even she truly understood.

A system that, if guided by will... could make miracles happen.

If I can sense the flow of space...

If I can grasp even the faintest thread of its essence... I might just catch a glimpse of Nihility's strikes—before they fall.

Her core began to glow softly.

A warmth like fire, flowing through her limbs.

Filling her with energy. With potential.

Under the nourishment of the core energy, her skin became extraordinarily sensitive—not in any way akin to normal sensory perception, but rather a new sense entirely, born from Kagura's will.

It was the manifestation of her own space-detection ability, brought into existence through the power of her core.

The only way to defeat the Queen of the Void was to acquire the same level of power—to perceive space as she did!

Of course, considering that the Space Stone held dominion over all spatial abilities in the universe, Kagura had no intention of contending for control of space itself.

What she sought was simply the ability to sense her opponent's spatial attacks. That alone would suffice.

Yes... I'm human. Just a weak, insignificant human.

But I am lucky.

I have this body—this perfected automaton vessel.

I've earned the recognition of the Soul Stone, granting me the power to perform miracles that could reshape reality itself!

With this strength as my vessel, I will carve out my own path in this universe—the world of Marvel!

Energy surged through her, flooding her body until pale blue lines of light traced every inch of her silver-haired form.

This was unlike any power she'd wielded before.

For the first time, Kagura broke free from the constraints of the system—this was a power born purely from her will.

If this ability were to bear a name, perhaps it would be... Complete Spatial Awareness.

[Complete Spatial Awareness: Activated]

'Whoosh—!'

In the next instant, Kagura charged forward once again toward the Queen of the Void.

Her silver blade cut through the air, trailing a storm of sparkling motes like distant stars in her wake.

Her core energy reserves plummeted rapidly—the cost of unleashing her Complete Spatial Awareness at its fullest potential.

'Vmmm—!'

The Queen of the Void's gaze trembled slightly, and Kagura felt the surrounding space violently distort.

She twisted her body mid-air, narrowly evading the attack.

The moment she shifted her path, a massive spatial shockwave ripped through where she would have been!

Glancing sideways, she caught sight of it—an invisible rift tearing through the very fabric of space, stretching along her original trajectory, a gash sharp enough to sever all things.

Had she not dodged in time, that invisible blade of space would have cleanly sliced off her head.

This feeling... so this is what her attacks are like!

For the first time, Kagura truly perceived the Queen's assault.

From here on, all she needed to do was keep dodging those invisible spatial strikes and close the distance!

[Charged Three-Dimensional Maneuvering: Activated]

Burning through her rapidly depleting core reserves, Kagura tensed every muscle, nerves stretched to the limit.

Her golden eyes gleamed as if set ablaze.

In her vision, there was only one target—the Queen of the Void.

'Vmm! Vmm! Vmm!'

Tears ripped through the space around her.

Ahead, the space distorted wildly as the Queen twisted it, stretching the distance between them endlessly despite Kagura's advance.

From this new perspective, the countless space rifts resembled a massive spider web—an elaborate minefield spread across the battlefield.

Entering recklessly would guarantee destruction.

And yet... none of this could halt Kagura's charge.

Thanks to Complete Spatial Awareness, the Queen's slashes could no longer strike the swift Kagura.

Even the spatial cage formed from warped space itself was seen through and evaded before completion.

The Queen of the Void watched as the silver-haired girl sped ever closer, breaking through every trap with flawless precision.

For the first time... the Queen smiled in satisfaction.

"Oh? It seems you've uncovered my little secret... Kagura, you are not so weak after all."

"It seems..."

"I may have underestimated the potential of humanity."

——

'Bzzt—!'

With one final, perfect evasive maneuver—pushing her body to its absolute limit—Kagura thrust her vibranium blade deep into the Queen's chest, her core energy utterly spent in that single decisive moment.

'Splurt—!'

Blue light burst from the wound as the two identical silver-haired girls embraced tightly.

"Not bad at all... For a mere human will to break through my defenses like this."

The Queen gently held the exhausted Kagura, her fingers softly caressing her cheek like the most affectionate of elder sisters.

"Well... I suppose I'll lend you my strength... just this once."

After all—

I was you to begin with.
