The Protagonist's Sister Is Actually The Strongest

The huge mecha that Zero Three piloted wasn’t just a simple robot, but it was specifically made for Zero One and her sisters to use and converge their powers into a vessel, unifying their powers into an ultimate robot, for a lack of a better term.

As their minds synchronized as one, their power coursed through the robot’s metallic body, rapidly beginning to transform and expanding, growing larger and more majestic. The colors of black, red, white, and gold flowed through its entire body.

The machine’s form grew more feminine in appearance, with longer legs and arms, and even blade-like fingers. Two new pairs of arms materialized on its shoulders and below its torso, and large jet plane-like wings appeared behind it, overflowing with golden and red light.

Its head remained looking mostly the same, although it now had long hair made of threads of golden light, with six eyes, two gold, two red, and two black colored eyes. Its aura continued growing stronger, expanding and resembling several humanoid bodies.

It wasn’t quite like hers, but it resembled Anna’s Myriad Self Arts, although it was born not from trying to copy her, but from the convergence of Zero One and her sister’s “Souls” and “Cores”.

The very core of their entire existence, the humanity they exuded from their minds and hearts, became a power, a supernatural force that became what the Titanic Chimera Machines were seeing.

However, to them it didn’t matter; they didn’t have to understand anything, not even how unfortunate they were to witness the birth of something beyond all of them.

They rushed forward, lacking the processing power to make other conjectures other than attempting to destroy their opponent, whom they deemed a failure and a traitor of their species.

RUMBLE!

The gigantic metallic hands rushed down towards the sisters from every angle, and yet, their six long, slender arms rapidly moved, summoning swords made out of nanobots and photon energy.

“{Thousand Blades}: {Starlight Tempest}”

Their voices were combined as one as they unleashed a devastating technique, swinging all swords upwards as they spun towards the mechanical hands approaching them.

SLASH! SLASH! SLASH! SLASH! SLASH! SLASH!

A storm of golden, black, and red slicing waves of pure destructive energy rapidly cleaved through the titan’s mechanical hands, tearing them into pieces one after another.

BOOMMM!!!

The arms exploded and fell into blazing fragments into the sea beneath; the titans were taken aback by the shockwaves generated by the explosions, as the fusion between the three sisters didn’t waste this opportunity.

They rushed towards the nearest titan, moving at lightning speed and using their swords while spinning like a drill to pierce through its body, easily finding the Core Robot that held the entire thing together!

CRAAASH!

But they didn’t stop there, as they immediately moved towards the next titan, and the next, and the next! Each one had their core pierced and then destroyed; explosions of burning wires and electricity erupted across the skies.

CRAASH! CRAASH! CRAASH! CRAASH!

All of these gigantic and tremendously powerful machines were utterly humiliated; unable to stay together once their cores were blown up, they fell apart and quickly exploded in quick succession.

The overload of energy and data without a core machine to keep them together ended up becoming their demise; most robots didn’t even need to be destroyed, as their own reckless plan ended up becoming their undoing.

“T-This is incredible! Our combined power is… I cannot believe it!” Zero One’s voice echoed from within the machine.

“It’s surprising…” Zero Two said. “Did we always have such strength?”

“I don’t really know, but this machine was designed by my Mother,” explained Zero Three. “She said it wasn’t just to protect me, but also to one day unify us… Perhaps deep down she knew this would happen one day.”

RUMBLE!

Their conversation, however, was quickly interrupted, as several more titans began to be rapidly assembled. The army of machines that the Mechanical Tree possessed was gigantic, tens of thousands, which allowed them to continue making these giants all they wanted.

As long as there were core machines to use, of course!

“We’ll take down all the Core Machines,” Zero Three said. “Are you two ready?”

“Yes!” Zero One nodded. “Let’s do this! We must put a stop to them!”

“I’m always ready!” Zero Two said.

“Good, let’s begin.”

Their minds synchronized, becoming a single and even larger, expanded mind. With their combined processing power and data, the sisters ascended into a being beyond machines.

FLAAASH!

Their Aura exuded, resembling a bright crimson, black, and red sun, expanding across the horizon. Everyone in the battlefield set their eyes on it as the gigantic flash of light, their mighty Aura, rapidly began to divide.

FLASH! FLASH! FLASH! FLASH!

All across the skies, long threads of gold, red, and black light pierced through the bodies of hundreds of robots at once, moving across the heavens unhindered.

Indeed, the three sisters were manipulating their aura and expanding it across hundreds of kilometers and dividing it into hundreds of threads that could pierce and destroy their targets.

The Core Machines, which were star-shaped, were immediately targeted everywhere, their heightened senses allowing them to easily find them anywhere.

BOOM! BOOM! BOOM! BOOM! BOOM!

They exploded into pieces one after another, as the plans of the Mechanical Tree to create as many titans as they wanted were completely foiled.

However, that didn’t mean that they couldn’t create more Core Machines; it only took a few minutes at most to create another batch of a hundred within its gigantic, internal factory.

So they had to hurry and get this done with it!

FLASH!

They flew as fast as possible towards the other party, as they saw a white tiger giantess pierce through the core of one of the titans with her massive claws.

CRAAASH!

“GAAAAGGH…!”

The robot groaned as its core exploded, the rest of its body rapidly collapsed down and exploding one robot at a time, as a rain of burning metallic junk fell into the seas.

“That’s Wai Tian! She has become so strong!”

Zero One smiled internally as she saw Wai Tian defeat one of the Titans on her own at long last. While they struggled, the tiger-kin girl had already found out its weakness with her powerful Ki Senses and Perception abilities, gained through her arduous training through both physical combat and meditation.

“ELIMINATE!”

The other titan, however, quickly swung its massive metallic claw at her, as Wia Tian put her arms in front of her while gritting her sharp fangs, receiving the blow head-on.

CLAAANK!

“Ugh!”

She felt the bones of her arms breaking as she was sent flying away, although she seemed to be smiling. The three android girls noticed several white flames covering the robot’s hands as they expanded through its arm and then towards the rest of its body.

FLUOSH!

“E-ERROR…! INTERNAL STRUCTURE HAS BEEN COMPROMISED…!”

The titan panicked; the flames were slowly draining its internal energies away! These were Wai Tian’s White Flames, a power that emerges from her after using her White Tiger Transformation.

“Now! Everyone!”

She screamed as the rest of the group surrounded the titan! Violet grew into a titanic size, the largest and longest she could, wrapping the robot’s legs, torso, and one of its arms together.

“GET OFF!”

The robot began punching Violet, but the centipede’s hard shell helped him resist some of the blows. Anna’s familiar had also been training and cultivating; his shell had evolved as he even attained a physique of his own, becoming tougher than ever before.

CLANK! CLANK! CLANK!

“SHYEEEH!”

As Violet roared and hissed at the robot angrily while enduring the blows, several other fighters appeared. Sara and Yin Sheng were riding a beautiful white and blue-colored wolf with horns made of ice crystals, Snow.

“AWOOOO!”

Snow howled loudly, as his entire Aura spread like an endless blizzard, spreading frost through the gigantic robot’s torso and arms, slowing it down considerably.

And then, Sara and Yin Sheng jumped off his back, Yin Sheng transforming into his Nine-Tailed Shadow Fox form, becoming much bigger, slender, and also menacing, encompassed by evil darkness and shadows.

“I shall assassinate you.”

He rapidly reached the robot, as Sara appeared by his side, both with their daggers in hand, and rapidly piercing through the frozen metal.

CRAAASH!

The core was still frozen in place, and unable to escape, it was easily destroyed by their combined dagger attack, being cut into countless pieces.

SLASH! SLASH! SLASH! SLASH!

BOOOM!

Zero One, Zero Two, and Zero Three glanced at the scene with great surprise. Although Zero One never doubted them, her sister didn’t quite know very well about her friends.

“T-They were able to take care of them on their own?! And I thought we were going to be the heroes that would save their lives here…!” Zero Two complained.

“Well, just be happy they aren’t incompetent,” Zero Three said.

“Don’t be so rude! Wai Tian, Yin Sheng, Sara, and Anna’s Familiars are all very strong!” Zero One complained, defending her friends. “Of course they would be alright! I never ever doubted them at all, in fact!”

As they reached their friend’s group, Wai Tian, who was being rapidly healed by Shiro, the white-colored Fox with Rabbit-like ears and tail, a powerful Angelic Beast that Anna hatched from an Egg she got as a reward from her first Class Trial in the Celestial Mausoleum, Yin Sheng and Sara seemed to panic a bit.

“Another robot is coming here!” Yin Sheng screamed. “Wai Tian! Are you ready to fight?!”

“I’m almost there! Ugh…!” Wai Tian muttered as she saw her bones quickly heal back completely and then her muscle fiber regrowing and wrapping against each other and then skin and fur grew back. “Incredible! Thank you, Shiro! Your healing always comes in clutch!”

“Kyuuuh…” Shiro wasn’t at all happy about it anyway; the Foxbit had been used as a flying potion the whole time, and the little rascal hated being forced to work so much. But Shiro also knew there wasn’t any point in complaining; their healing powers and also barriers and buffs were very important for everyone’s survival.

As the entire group was about to face this new incoming threat, the massive machine stopped flying towards them, pointing their open hands at them while waving them, panicking.

“W-Wait a bit! I am not an enemyyyyy!” Zero One’s voice echoed from it. “It’s me! Zero One!”

“And me too, by the way,” Zero Two said.

“…” Zero Three remained in silence.

“HUH?!”

Wai Tian and the rest of the group gasped in disbelief.

They couldn’t quite understand how these two girls somehow fused into this giant robot, but it sure looked strong!
