OP Sister Chapter 423: Elementals

-----

“{Myriad Blade Arts}: {Horizon-Splitting Slash}!”

With all her strength, she spun forward, swinging her swords horizontally and cutting right through the elemental’s blazing body! 

SLAAASH!

“…!?”

The Elemental, which thought the attack wouldn’t even affect it, suddenly felt its entire elemental structure collapse, exploding into red-colored pixel data. 

BOOOM!

“They might’ve been strong, but remember that we’re not in the real world, and those aren’t true Elementals, but clumps of Data!” Zero One said. “And—” 

RUMBLE!

As she spoke, another Elemental descended from the skies as a huge black cloud summoned a large Thunder Elemental, taking the shape of a giant, coiling dragon. 

“ROOOAARR!”

And this one roared mightily, rushing down with its giant jaws wide open. 

“Okay, I take back what I said, RUN!” 

Zero One and her sisters quickly took off, the Thunder Elemental chasing them as it destroyed buildings everywhere it went. 

BOOM! BOOM! BOOM!

“That thing’s gigantic!” Zero Two said. “Can we even defeat something made of thunder?!” 

“Maybe if we concentrate and fight it together, but we don’t have time for that!” said Zero One. 

“Sister, the hole is over there, look!” Zero Three A said. 

As they discussed, Zero Three A, the more serious of the group, pointed into the distance. There was a giant hole—or a wound—in the middle of this ruined city.

There wasn’t a parasite like before, though, but it was surrounded by three other Elementals!

One Elemental of Fire, one of Light, and a third of Wind.

They were constantly releasing their Elemental Auras, causing chaos and destroying buildings, trying to crush them into smithereens.

It seemed they were frustrated there weren’t any humans to kill. 

“Dammit! Fucking Elementals!” 

Zero Two grew angrier. Her Data erupted with power as she concentrated her processing energy into manifesting her former equipment.

Her whole body was covered in a swarm of black nanobot-like data, which assembled into a skin-tight black and red suit around her body—a super tough armor resembling simply a bodysuit.

Then, she created two long black and red katanas overflowing with data flames. 

“Let’s kill them all, Zero One! We don’t have any other alternative anyway!” 

“I guess you’re right! Move down now, though!” 

Zero One expanded her golden aura, grabbing her sisters and descending a second before the Thunder Elemental was about to crash into them. 

CRAAASH!

And instead, it ended up slamming into the Fire Elemental. The contrasting elements exploded, damaging both Elementals more than they would have wanted. 

BOOOM!

As the Fire and Thunder Elementals fell to the ground weakened, the Elemental of Wind—resembling a beautiful woman made of pure golden and white luminescent light—and a giant genie-like Wind Elemental glanced down below, noticing the ruckus.

They didn’t attack one another like Monsters invading Earth would usually do, as Anna had told Zero One about her world many times. They seemed to all belong to the same team, working together.

Therefore, once they saw that, they were quite confused! 

“They’re confused, go, go, go!” 

Zero One led her sisters as they rushed and ambushed the Wind Elemental, catching it off guard and attacking it with everything they had. 

“Take this!” 

Zero Two roared, swinging her two katanas while spinning as she descended, unleashing a tornado of fiery red slashing waves, cutting through the Wind Elemental’s data. 

SLASH! SLASH! SLASH!

At the same time, the Zero Three twins combined into a giant golden machine, firing a beam of light from their chest and blasting half of the Wind Elemental’s body right away. 

BOOOM!

“…?!” 

As the Wind Elemental agonized while glaring at them with surprise, it swung all four of its muscular-looking arms made of spiraling emerald winds, attacking the girls with powerful slicing winds and strong shockwaves. 

BAAM! BAAM! BAAM! BAAM!

Zero Two and the Zero Three twins were sent flying away as Zero One attacked it in that very moment, using her two swords to finish it off. 

“{Myriad Blade Arts}: {Lightning Blade Storm}!” 

Combining her electromagnetic energies into the technique, she unleashed a completely original technique altogether, engulfing the Wind Elemental in a storm of thunderous slashing attacks. 

SLASH! SLASH! SLASH! SLASH! SLASH!

The Wind Elemental agonized, its entire body being divided into pieces and then exploding into green-colored pixels, its corrupted data cleansed. 

BOOOM!

“W-Watch out!” 

Zero Two called everyone as she noticed the Light Elemental appear in front of them, moving almost as if teleporting through space!

The Elemental raised her hands, as dozens of spheres of light manifested in a split second, which then fired dozens of beams of light while rotating around her body. 

BOOM! BOOM! BOOM!

They were quickly bombarded with dozens of super-fast laser beams that could hardly be avoided! The trio quickly hid behind rubble and buildings, but they were instantly destroyed. 

“Dammit, if only Bastet was here! Her mirror was amazing at absorbing light!” Zero Two complained. 

“Right, the mirror!” Zero One nodded. “If I could create swords with this power, then…!” 

Zero One suddenly amassed large quantities of environmental Data into her hands, fusing and compressing them using her own internal data to modify it. 

FLUOSH!

And as the Light Elemental rampaged, a huge red mirror was manifested, floating in front of Zero One, who jumped into the action despite the danger. 

“It’s now or never!” 

Zero One fearlessly leaped into danger, pushing the red mirror in front of her and letting the Light Elemental blast it with its light, absorbing the light constantly as she reached it and then slammed the Elemental with the mirror itself. 

CLAAASH!

The mirror shattered into pieces as the Elemental took a great amount of damage to its own internal data body. Zero One swiftly stabbed it with her swords, encompassing them with darkness. 

“HYAAAH!” 

Like a brave warrior, Zero One pushed the data creature into the ground, filling its bright body with darkness until all light was extinguished, and then it perished, fading away into black and white pixels. 

POOF!

As Zero One finished that one off, the Thunder Elemental and the Fire Elemental rapidly stood back up, glaring at the scene. The two seemed intimidated to an extent. 

“A-Are they scared of her?” Zero Two wondered, walking to her sister’s side. 

“They better be!” Zero Three A said. 

“Go away!” Zero Three B said. 

Both spoke through their giant golden mech form. 

“W-Wait, they’re…?!” 

However, instead of escaping, the two weakened Elementals began to dissolve into one another, merging out of nowhere. 

FLUOSH!

Suddenly, a massive draconic humanoid entity emerged, made of red flames and golden thunder, overflowing with elemental prowess. 

“HAAAAHH!” 

It released a mighty roar, spreading its four muscular, scaled arms into the skies and unleashing an inferno of flames and thunder everywhere! 

RUMBLE!

The buildings around them collapsed one after another as Zero One and her sisters were pushed back once more, its elemental power completely overwhelming!

However, the hole was right behind them… 

“Zero One, let’s jump down and ignore this bastard!” Zero Two said. 

“No, that won’t do!” Zero One said. “I can detect corrupted data within it! This thing and the other Elementals are like that Virus as well! But they’re camouflaging by using Mother’s Memory Data to create bodies…! If we want to heal her, we must destroy that thing.” 

“RAAAAHH!” 

The Fused Elemental roared, rushing toward the girls as it brought with it storms and infernal flames, spreading across the entire city. 

“Can we even go against such a thing?!” Zero Two doubted once more. 

“Yes, as one!” Zero One said, hugging her sisters through her Aura and pulling them toward her. “Let’s combine our Data, quickly!” 

“Y-Yeah!” 

“Okay.” 

“Let’s do it.” 

FLAAASH!

As the Elemental’s giant blazing and thunderous claws descended to destroy them, an explosion of crimson, golden, and silver light emerged, blowing its claws into pure pixels of data! 

BOOOMM!!

“NGGHH?!” 

The Fused Elemental stepped back, glaring at what had emerged from the fusion—a tall woman with a slender body, made of three colors constantly moving and swirling around her data-made body.

Its appearance resembled Anna’s Cosmic Form a lot, and it was also where Zero One drew a lot of inspiration for this transformation. 

“We can’t keep this form for long… So let’s end this!” 

They rushed forward, swinging their small arms toward the Elemental, which confronted them with fire and thunder. 

BAAM! BAAM! BAAM! BAAM!

“GRAAAH?!” 

The Elemental screamed in pain; its entire body riddled with holes. The little punches released tri-color explosions, weakening the Elemental and pushing it back constantly.

As this happened, the Elemental screamed, and several serpents made of fire and thunder surged from its shoulders, attacking the fusion constantly.

The girl raised four more arms, clashing against all the serpents at once. 

CLASH! CLASH! CLASH! CLASH!

All of them exploded as the girl pushed forward, manifesting a giant rainbow sword made of their compressed data. 

“This is the end!” 

Anna fueled her mind with imagination once more. 

“{Myriad Blade Arts}: {Rainbow Sunshine Blade}!” 

SLAAAASH!

The Elemental screamed, its entire body divided into two halves as its whole being exploded into data, erupting and disappearing. 

BOOOMM!!

As the fusion glanced at the Elemental disappear, the four sisters separated, looking behind them. The light they unleashed healed the wound behind them. They had to hurry. 

“We did it!” Zero Two celebrated. 

“Yeah, yeah, let’s hurry!” The Zero Three sisters cried, fusing again and grabbing the two of them. Zero One was still dizzy. “Let’s go!” 

As they jumped through the hole and fell across several clumps of data as it all healed, the third layer revealed itself before them.

And this time, it wasn’t a big and expansive landscape, but a futuristic-looking underground laboratory.
