Well, following the previous message, it's a pleasure to know that many people have enjoyed my stories. I send a warm greeting to all, my friends; I'm KaleidoMirror.

I wrote with sincerity and a deep appreciation for the works and franchises of RWBY and Fate/Stay Night.

That's why I bring you Chapter 3; I hope you like it since this is the new updated version, with the corresponding fixes, to enhance the reading. Without further ado, let's begin.

Greetings to everyone.

The icy and cutting wind whispered across the vast desolate expanse of the wasteland as the elite squad of Atlas soldiers carved their way through the dense tundra and the relentless weather of that inhospitable region.

Leading the formation was the newly promoted Field Officer Ironwood, never ceasing to analyze the position on the holographic map constantly. "Maintain your positions," he instructed. "Our priority is to keep the perimeter and not lower our guard against potential Grimm threats."

The soldiers' silent nods were the response, deploying a new formation in a coordinated manner. They kept in mind their mission to explore and maintain reconnaissance of the surrounding area.

Despite intelligence reports suggesting unusual activity in the last twelve hours, Ironwood maintained his caution. "I think you should take a look at this, my Officer," commented Jensen, a first-class soldier, with a hint of disbelief in his voice. Ironwood directed his gaze towards the uneven and rugged terrain, revealing unprecedented devastation.

The surviving trees showed uneven burns, the snow had melted, and a gigantic crater of over a kilometer in diameter, with an uncertain depth, marked the dramatic change in one of the designated areas.

"We cannot overlook these findings," declared Ironwood, assessing the troops distributed in five groups. "Let's reaffirm and compare the changes in geography."

He stepped back to meet with the squadron leaders, whose faces reflected military discipline and determination. "Everyone should proceed according to military protocol. The mission's objective is clear: investigate what is happening in this remote region of Remnant," he sighed before reloading his weapon. "I don't want anyone to fall to the Grimms. Keep constant communication between the groups, understood?"

"Yes, my Officer," they responded in unison, displaying proper military composure.

Breaking into rows, they regrouped with their gaze fixed forward, inspecting any changes in the environment. They maintained vigilance as they advanced towards their next objectives.

The journey became increasingly relentless, with a cold that penetrated to the bones and challenging gusts of wind carrying the sinister whisper of the snowstorm. Every step of the squad resonated in the silence; changes in the environment kept everyone on alert, revealing that something monumental had happened; it was inevitable to think of an event capable of affecting such a vast expanse.

"It was madness!" exclaimed someone in the group as they observed the changes spreading for kilometers around. Desolation seized the landscape: shattered vegetation, smoking craters, and black mud, unmistakable signs of escalating devastation that generated an unsettling feeling of discomfort in the hearts of the soldiers.

Through silent signals, the order to regroup spread. Ironwood took command: "Maintain flanks on standby." However, tranquility was ephemeral, interrupted when the silence was torn apart.

"Howl!"

"Trumpet!"

"Roar!"

From the depths of craters and among the trees, shadows emerged suddenly. From the cliffs on the periphery of their vision, their presence was undeniable: the Grimm, dark and terrifying creatures lurking in the darkness, had set up an ambush, taking everyone by surprise.

"Meidey, repeat, Meidey to all," echoed the voice of one of the men on the communications, firm but with a trace of nervousness, to all units. "I repeat, we are under attack. Everyone must maintain counterattack maneuvers."

"Divide into two response forces for each group to have more reach in their deployment area," Ironwood added with determination. "We'll add impact strikes; I want both forces to switch between intervals of three minutes." He unsheathed his weapons as he cracked his neck, ready to lead in the battle.

"Understood here, Beta team, in position."

"Here, Gamma team, at the impact point."

"We're pinned, Delta team, holding ground, but facing constant aerial attacks."

There was an echo among the transmissions, but everyone held their positions. "I want constant updates every five minutes from all four sides of the impact point. Alpha team will follow me, and we'll be reinforcements based on the combat's evolution. Everyone on standby and ready, Now!"

Explosions of dust illuminated the night, but the darkness that represented the Grimm seemed to devour every ray of hope. But what mattered most was discipline and their duty as proud members of the Kingdom of Atlas. That was something everyone present found themselves taking positions with the resolution to put their lives on the line, aware that every move would define the destiny of that frozen night.

The frigid night persisted, intermittently illuminated by flashes of weapons, but their light paled against the cutting wind and the deafening tumult of battle. The roars of the Grimm echoed in the air, creating a cacophony of terrors as the ranks of soldiers tried to stand firm, erecting a barrier to withstand the onslaught. But it was hard to maintain morale; the overwhelming number of Grimm surpassed the initial tactics of the Atlas soldiers.

Amidst all the chaos, Officer Ironwood tried to instill calm as he gave orders through the communications. "Hold your positions, soldiers! The battle is not lost yet. Reinforce the inner line and hold," his voice echoed, firm but urgent.

"We're being overwhelmed!" exclaimed a soldier, barely audible amid the roars of the beasts.

"Hold on, Delta team! Officer Ironwood is on the way!" replied another voice, trying to inject hope into the midst of despair.

The sounds of weapon clashes and claws intermingled with the soldiers' shouts and the roars of the beasts. Suddenly, a thunderous blow resonated, marking the beginning of the decline. The Grimm, driven by unbridled fury, outnumbered and outpowered the soldiers.

The sound of gunfire and the clash of metal against claw were deafening, but Ironwood persisted in leading the resistance. "Beta team, maintain a strong front. We'll be on our way with reinforcements shortly. Just keep the pace for a few more minutes," he urged, his voice resonating through the soldiers' earpieces.

Despite fighting fiercely on the front line, it wasn't enough, despite putting everything on the line using his tactical prowess and combat skills, there seemed to be no significant change in the inevitable course of the battle. The sounds of bones breaking and beasts roaring in victory filled the air as soldiers fell one after another.

Meanwhile, the struggle intensified, but amid the cries and roars, a note of determination emerged. "We can't yield now! Stand strong, soldiers!" exclaimed a squad leader, seeking to boost the morale of his comrades.

Communications were filled with reports of losses and requests for reinforcements. The Atlas soldiers, now fighting in desperation, were overwhelmed by the unstoppable tide of the Grimm. The sight of devastation intertwined with the sounds of battle: cries of pain, triumphant roars of Grimm, and the thunder of the unequal fight.

"Gamma team, hold your ground. We have to maintain this position until we can evacuate the wounded. Don't let the Grimm advance any further!"

The chaos of battle seemed to find a momentary pause as soldiers redoubled their efforts. In the midst of the tumult, the voice of one of the groups resonated. "We just have to hold on a little longer! We must keep resisting until we can turn the tide!"

Despite the soldiers' bravery, the battle tilted toward the dark side. The sounds of blows and carnage intensified, marking the tragic surrender of the squad to the unstoppable force of the creatures of darkness. Amidst the chaos, darkness swallowed every ray of hope, leaving behind a desolate and silent battlefield, only interrupted by the victorious roars of the Grimm.

As the conflict prolonged, Jensen felt a knot in his stomach, a mix of distress and determination, as he struggled to maintain composure. The faces of his comrades, with whom he had shared laughter and training, paraded before him, each one dragged away in the chaos of battle. The cries of anguish and fear were lost in the howling wind and the roars of the Grimm.

The fight for survival was palpable; every word and action resonated with an undertone of desperation. Soldiers clung to the belief that, guided by Ironwood, they could change the fate of that cold night. However, their surroundings constantly reminded them of the brutal reality.

Surrounded by packs of Goliaths, the soldiers found themselves ensnared in deadly traps created by the destruction of the surrounding trees. But the real threat came from three imposing Frost Geists, strategically used to keep even the most experienced soldiers at bay. Meanwhile, Griffons and Manticores reveled in picking off those fleeing the battlefield.

Desperation gripped Jensen as he witnessed the fall of his friend, Sergeant Harris, to a Beowolf. He ran toward him, desperately firing at point-blank range, but fate had already been sealed. The Beowolf had snatched Harris's life before his very eyes.

Despite efforts, discipline on the battlefield was crumbling. The Grimm seemed inexhaustible, relentless in their fury. Every bullet fired and every inflicted wound proved insufficient to stop the onslaught of the dark creatures.

As he fought, tears froze on Jensen's cheeks, and the cold seemed to penetrate the depths of his soul. The Grimm showed no mercy, and every attempt at resistance was met with more ferocity.

Looking around, he saw his comrades fall one by one. Although the odds were against them, Jensen refused to give up. He reloaded his dust-infused weapon once more, ready to face his fate with courage, determined to honor his fallen friends.

In the midst of horror, Jensen understood the true nature of the struggle in Remnant: a desperate battle for survival in a world where darkness lurked in every corner and hope was fleeting.

However, in an unexpected turn of events, a powerful battle cry resonated from deep within the forest, marking a turning point amid the war zone between the hordes of powerful Grimm.

With astonishment and bewilderment, Jensen watched two unknown youths emerge from the corroded trees, entering the battlefield infested with death and despair. He examined their features, their tattered clothes, and their determined faces hinted at their intentions. However, what surprised him the most was the mysterious navy-blue glow enveloping their bodies.

The elder, a red-haired boy, firmly held a simple stick, also infused with the same light. The younger, a black-haired girl, assumed a defensive position, throwing shining stones with astonishing precision at nearby Grimm.

"Whoosh!"

"Squish!"

"Crunch!"

"Boom!"

In the blink of an eye, the young red-haired boy faced two imposing Beowolves but remained undisturbed, delivering powerful blows between the heads of the Grimm, not allowing them to react. Both ended up on the ground completely stunned before being finished off with a powerful final blow to their skulls, disappearing into the dark dust.

"Bang!"

"Pew pew!"

From the air, Griffons with damaged wings descended to the ground and were finished off with wounds of varying degrees. The small black-haired girl remained calm and steadfast in her own task, allowing nearby soldiers to deal with the fallen prey from the sky.

Throughout this time, both Shirou and Miyu had applied first aid to themselves, treating their previous injuries at a fundamental level, but these worsened over time, resulting in new wounds that slowed their movements and added the weight of physical and mental exhaustion. Yet, they remained consistent and firm in their confrontations. Both fought with determination, anticipating and using everything in the field that could give them an advantage without exaggerating in useless movements. They needed to show themselves sufficiently fast and coordinated in their attacks, being fully aware of their own limitations and the limits of their improvised weapons.

But that didn't stop them from shining on their own. Sadly, the reality was harsh; their efforts in the overall scope of the battle didn't make a notable difference against the dark creatures, but it was evident to every life they saved that their effort and determination were undeniable.

"What the hell just happened? It was complete madness! How was it possible to end the Grimm like that?" Jensen, perplexed, wondered who these young people were and how they had arrived. Refugees? Orphans from a nearby village? What motivated them to face such chaos?

Despite the unanswered questions, the actions of the young ones provided a brief respite in the midst of the chaos. While the Grimm were taken by surprise by the intruders, the soldiers of Atlas momentarily regained vigor, preparing for a counterattack.

Jensen, admiring the bravery of the young ones, thanked from the bottom of his heart for the ray of hope they had brought to Remnant's darkness. The fight was not over yet, but in that brief moment, he felt that the balance tipped toward the side of hope.

Shirou panted, feeling exhaustion accumulating in his body as he swung his improvised wooden sword against the Grimm. A heavy sigh escaped his lips, and although fatigue weighed on him, his determination remained steadfast.

Each blow he struck depleted his limited mana, but Shirou didn't falter. Aware that his magical energy was rapidly depleting, he feared running out of resources before being able to replenish them. Despite this, his mind was focused on protecting those around him, especially the safety of Miyu, his younger sister.

"Well, well," he snorted, finding a glimmer of humor amid the chaos. "Who would have thought that being a big brother is a never-ending job?" Wiping the sweat from his forehead, he faced a new Beowolf with determination. "But if it's for Miyu, I'll be her hero whenever needed!"

While Shirou faced the creatures, Miyu, on the other hand, was in another corner of the battlefield coordinating with the soldiers. The defenders, surrounding her, showed exceptional teamwork. However, the situation was critical, and ammunition was running out quickly.

"Miss...," expressed a worried soldier.

"Don't worry," Miyu replied calmly, approaching the soldiers. Her hands touched the weapons, which began to glow in shades of blue. "You can shoot with the same intensity. Just be careful with the covering fire before reinforcements arrive."

"What reinforcements?" asked a skeptical soldier as he watched his weapon glow intensely.

Miyu, from her position, launched mana-infused explosive projectiles, keeping Manticores and Beowolves at bay, contributing to the group's defense. "To my reliable brother, who just confirmed that we must give it our all one last time."

Both siblings were determined to give their best in this cause. Despite how exhausting the battle became, their unwavering determination shone as they fought to protect those in danger in that unknown and dangerous world.

In the height of the confrontation, the fierce Grimm hordes continued their relentless attack, an endless succession of waves. Despite the valiant efforts of the Atlas soldiers, they found themselves on the verge of being overwhelmed. In the midst of this whirlwind, two brothers stood back to back, facing a battle that seemed insurmountable.

Their gazes intertwined in a final exchange, understanding that this could be their definitive farewell. In a life marked by the tragic union of death and loss, they felt strangely comforted by each other's presence, determined to fight until their last breath.

While dealing with the creatures called Grimm, bittersweet reminiscences of their bond that had transcended to this new world surfaced in some corner of their minds. They immersed themselves in memories, both joyful and sorrowful, shared while living together, reaffirming their fraternal bond and revealing themselves to each other.

"Shirou."

"Tell me, Miyu."

"It's funny, isn't it?" Miyu's voice resonated with a bittersweet tone, and in her gaze, Shirou caught a sense of longing.

"Do you mean how things can never be as one wishes, or..." letting out a weary sigh, he shook his head, but his voice cracked as he watched a solitary tear escape from his little sister's eyes, "or that, in the end, nothing we do allows us to be free?"

"Maybe you're right," Miyu affirmed, wiping her right eye and keeping her gaze fixed on Shirou, "but in the end, was Kiritsugu-san right back then?"

Shirou shook his head as he exhaled, letting a trail of steam dissipate. "I don't know, but that full moon was really beautiful. Too bad we'll never see one like it."

"That is certainly sad," both chuckled for a moment, their voices interspersed with the mix of emotions they felt.

It was hard to explain, but both experienced a range of feelings toward the Emiya patriarch. Even if they had different stances on him, they silently thanked their stepfather, who, in some way, had marked a change and a new beginning in their lives. At the same time, they clung to the joy of being together in this new world, an opportunity life had granted them, albeit ephemeral and bittersweet.

Despite the fatigue enveloping their bodies completely, beyond weakness, something inside them remained steadfast. Something that had never been seen in this world, resonating deep within their souls, unbroken.

They smiled one last time before embracing, conveying with that gesture what words couldn't express: love, gratitude, fraternity, and happiness. The profound fraternal bond between the two siblings transcended worlds and stood firm even in the darkest night.

They were not aware of how much time passed, but it was enough for both to feel the warmth they sought so much, but eventually, they had to part ways before heading in opposite directions with a goal in mind. They looked at each other from a distance, with Shirou in the frontline and Miyu from behind. Each whispered the last words to the other.

"Miyu, whatever happens, I'm grateful that we met in this world," Shirou's speed increased as he faced and countered the venomous attack of a Manticore, smashing its skull with the branch, propelling himself against the snow on the ground.

"Shirou, I wish that we're always together once more!" Miyu maintained a slight smile on her face, knocking down a couple of airborne Grimms that had lunged towards her, avoiding them at the last moment.

At that moment, with their determination at its peak and using their last reserves of magical energy, both charged against the Grimm hordes. They confronted the darkness and chaos of the creatures with courage and fraternal love. Even if they didn't survive, they were willing to give everything for the soldiers of Atlas and the uncertain future that awaited them.

In the midst of the battle, Shirou and Miyu fought like two souls destined to rely on each other, facing adversity with courage and
