Chapter 96: [95] Declaration and Technology

That morning, the sky over Samsara reflected a soft amber hue across the warming desert. The remnants of the night wind drifted gently, carrying the scent of freshly shifted sand and the fading smoke of a dying campfire.

Tents were being dismantled one by one, and movement slowly stirred in the small square where the Band of Massiah had stayed the night. Susan was busy checking water satchels and supplies, while Nea helped rewrap the medicinal herbs she had dried the night before.

The Hassasin stood in silent formation, as if they had never slept at all. Their pitch-black cloaks fluttered in the morning breeze, and beneath the fabric, sharp eyes remained alert to any direction not yet tamed.

Inside that strange van, Nico Mustang—a name known by many. But to the few who truly knew him, he was Rentaro Takamura, or just Ren. A silver-black-haired man with bright blue eyes, usually brimming with energy. He was fiddling with something while patching up his Mark 2 armor.

And then, the voice came. Deep, calm, and carrying the weight of an ancient gong struck slowly in the chest."Are you all ready?"

Every member of the Band of Massiah instinctively turned toward the sound. The movement was synchronized—not from military order, but because the voice carried something heavier than a summons—a decision that infected the air around them.

Khan stood at the main pathway’s edge. A deep blue turban wrapped around his head, not hiding the upright wolf ears that now stood unashamed—declaring that he no longer hid the blood in his veins. His face was clean-shaven—and without the beard, his full charisma shone through: the face of a Persian leader, not only bold, but bearing the weight of a legacy.

His battle garb reflected the morning sun. Not grand, but solid. There were no excessive ornaments—only metal plates and regal cloth in earthen tones, woven with fine gold thread once reserved for palace heirs.

There was a moment of silence. Even the wind seemed to hesitate. From Hassasin to young healers, all eyes were on him, breaths held—and like a slow-spreading wave, awe bloomed in silence.

Khan stepped forward, each footfall a soft rasp of metal and sand. His gaze swept over the faces before him—soldiers, refugees, healers, toolmakers, and shadow-fighters. They were not a royal army. They were people who had lost everything, but chose to live on... and now waited for direction.

"I once said I wanted nothing to do with Samsara," he said, his voice resonant but never raised. "I ran from it, called it a curse, blamed blood and fate."

No one moved. Even Nea, standing near the Hassasin, bowed her head—not just in respect for his words, but for the courage born of confession.

"But last night..." Khan exhaled, his fists clenched at his sides. "I saw what happens if we stay silent. Not just war or ruin. But the ruin of souls. The people we love... stripped from themselves. And that’s not fate. That’s a choice."

His eyes burned brighter, like embers newly lit. "So today, I make my choice."

He stood tall, chest forward, no longer hiding the form that others had long called ’other.’"I, Farid bin Malik, of mixed blood from palace and exile, declare that I will stand. Not as a sultan—but as a shield."

A murmur spread—some from awe, some from relief. For some, this was a prayer answered. For others, the inevitable beginning of a new Chapter.

"I won’t sit on a throne built from suffering. But I will be the wall between our people and destruction. If that means war, then we’ll fight. If peace, then we’ll make it. But whatever it is... we’ll choose it ourselves—not be forced into it by some rotting miracle."

From inside the van, Ren powered down his welding torch. His eyes sharpened. He knew: this was the moment their story shifted course.

Khan raised his hand—not in command, but in invitation."I’m not giving orders. I’m asking. Anyone who wants to end the cycle of oppression... stand with me."

And slowly, one by one, they moved. The Hassasin bowed their heads in quiet loyalty. Susan gripped her weapon calmly, her eyes steady with conviction. Nea stepped forward, taking her place at Khan’s side without a word—her presence alone enough to say she chose to stand with him.

From the van, Ren finally emerged, descending the ramp while hoisting the half-finished Mark 2 helmet. His face bore that signature crooked smile—a blend of respect and mischief.

"Well, well... so you’ve finally made your mind up?" he asked, grinning.

"Yeah," Khan replied, short but firm.

"Sure-sure?"

Khan turned to him, eyes locked onto Ren’s sky-blue stare lit by morning sun. "I need to prove my words, don’t I?"

Ren chuckled. "That’s right... But let me ask you one important thing—what’s your plan to break through three thousand troops?"

Khan took a slow breath, then answered in a tone so calm it echoed like a war drum."My plan? Walk straight through... and kick their asses one by one."

Ren raised an eyebrow. "Heh. With a force of less than fifty?"

"Why not?" Khan answered, a faint smile laced with unshakable resolve.

Their gaze locked—not as rivals, but in mutual recognition. Ren wasn’t part of the Band of Massiah. He was a guest, a wanderer from another world, and currently on his own mission: to return the Tiger family to the penal plains, homeland of Alfered and Bella.

But for a moment, Khan’s idealism and determination shook the boundaries Ren had always kept.

"Alright then..." Ren said at last, tapping his Mark 2 helmet. "We’ll follow your plan. But let me just say this."

Khan looked over, brow raised slightly. "What’s that?"

Ren flashed a wide grin. "If we die out there, I’m putting your name first on the list of people to blame for this mess."

They both laughed. And between them, for the first time... not just a plan, but trust had begun to take root.

Ren stepped back into his cramped van, dimly lit with the glow of blue panels and unfamiliar instruments not of this world. The air inside was warm, saturated with the scent of hot metal and ozone—the distinct smell of high-tech machinery at work.

He slumped into a seat half-detached from its mount, then turned to a holographic panel that lit up automatically, recognizing his fingerprint."Ultro, status update?" he asked casually.

『75%. No anomalies, Master,』replied a synthetic voice from a small speaker tucked into the van’s ceiling—Ultro, his AI assistant brought over from Earth, now adapted to this world’s alien environment.

Ren gave a small nod, his eyes shifting toward a black crate in the corner, partially open and releasing wisps of bluish vapor. Inside, the Mark II armor lay like a body mid-birth—half-assembled, its left arm fitted with a smart missile launcher, and the right shoulder being affixed with a laser module.

None of the materials for these weapons or tech came from this planet. Ren relied on his ability—Material Transmutation

—to create what would otherwise be impossible to find in this medieval world. He transformed raw elements—even water—into ultra-grade metal, explosive compounds, and polymer materials that normally required 21st-century manufacturing.

The process wasn’t magic. He had to understand the atomic structure of each element, recalculate molecular formulas, and adjust micro-temperatures and pressures. To produce acetic acid, for example, he had to recall the formula C₂H₄O₂ and precisely combine functional groups. It wasn’t enough to know the name—he had to know how the world worked, down to its most fundamental level.

As limitless as his powers sounded, the process was grueling. Ren needed time, energy, and exact knowledge. Even the slightest mistake could yield unstable—or deadly—results. Thankfully, his brain wasn’t ordinary. He was a prodigy in material engineering, a science-obsessed genius and master craftsman despite his young age.

Ren approached the crate, eyes reflecting the soft pulse of the cooling module’s light."A little slow... is the TAF module really that hard to install?" he muttered, eyeing the armor’s open chest—carbon-titanium ribs exposed like the mechanical equivalent of bones.

TAF—Time Acceleration Field. A localized temporal field that accelerated the flow of time within a small radius. On Earth, this tech was considered pure fantasy—akin to time travel folklore. But Ren had built it. And now, the module was being integrated into the Mark II’s core: to boost movement speed, enable real-time system refresh, and, if successful, serve as a last-resort failsafe.

The armor’s chest opened with a soft hiss of air pressure and a puff of cool mist. Beneath it, a complex mechanism revealed itself—a floating metal ring suspended between two opposing magnetic fields, rotating slowly with a flicker of violet electricity. The pulsing glow throbbed like a synthetic heart preparing to beat at inhuman speed.

When acceleration mode was activated, that ring would unleash a burst of invisible particles, creating the Time Acceleration Field—a manmade space-time distortion enveloping only the wearer’s body. The Mark II’s entire system would operate at hyper speed, while the user inside remained stable, unaffected by biological stress. This wasn’t just an innovation—it was a revolution.

But the armor’s true secret wasn’t just its temporal engine. The entire Mark II body was forged from an alloy of titanium and mithril—a hybrid metal created by Ren through transmutation, blending Earth’s metallurgy with materials from this isekai world. Yet the real core sat at its heart—a mysterious gem known as the Rune Stone of Endurance.

The Rune Stone emitted a strange energy that flowed through the entire armor structure, strengthening molecular bonds and enhancing durability to previously unimaginable levels. It didn’t just absorb physical damage—it could take in magical energy and extreme heat without losing structural integrity.

Ren had first discovered the stone’s potential in a brutal fight against Veskar—a man-sized mutant hornet with an exoskeleton as tough as iron. In that life-or-death struggle, Veskar was immune to blades and shrugged off energy projectiles. That’s when Ren realized—this world contained materials that could rival, even surpass, modern technology.

Now, the Rune Stone of Endurance was embedded in the Mark II’s chest—not as a fancy ornament, but as a vital stabilizer. It was fused with the TAF module, channeling ancient energy that modern science still couldn’t fully explain.

’But I’m still annoyed I can’t apply the same principle directly to the armor’s outer layers,’ Ren thought, frowning slightly as he stared at the gem.

As a scientist—or rather, an extreme engineer—Ren was never comfortable working with elements he didn’t fully understand. Though he’d analyzed the Rune Stone’s structure and reactions through simulations and field tests, its mysterious energy essence remained beyond his logical reach.

He’d tried everything to inject or transfer the stone’s energy directly into the mithril-titanium alloy, but every test resulted in unstable fields—or, worse, small-scale explosions. In the end, the only practical solution was embedding the stone directly into the armor’s core.

This way, when the Time Acceleration Field activated and the whole body surged into overdrive, the Rune Stone would regulate energy flow and pressure balance from the central point. Without it, his body might collapse under the time differential between him and the armor.

To Ren, it was a compromise. A decision that clashed with his principle of always understanding what he used. But he also knew—in this world, not everything could be explained by science alone.

"At least this beats being crushed in the first second of activation," he muttered, half resigned, half wondering if someday he’d crack the mystery of an energy source that defied all equations.
