Location: Western Palisade, The Bridge, Kiyosu Castle.
Current Date/Time: Morning. Late Summer, 1559.
The inside of the cedar supply shed was dead quiet. The air was thick with the smell of wet wood shavings and fresh blood. Oda Nobunaga’s waraji straw boots had already faded out into the morning fog, but the pressure of his presence still hung within the four walls.
Soma Kurogane stood completely rigid in the center of the dirt floor, staring down at the dead Saito operative. The spy’s eyes were still wide, staring blankly at the timber roof. Dark blood was already soaking into the dry ground, leaving a slick, expanding puddle in the dim light.
Soma ground his back teeth together, clenching his fists at his sides to fight down a sudden wave of nausea. Back in Tokyo, a major project failure meant cracked concrete or a legal dispute over broken steel. Here, a failure meant watching a man’s throat get slit right in front of your face. He forced his mind to look at the physical mechanics of the strike to keep his hands from shaking. To drive a blade straight through a human hand and bury the iron deep into a solid cedar column took raw, terrifying leverage. Nobunaga hadn’t just swung a blade. He hit that post like a heavy iron ram, throwing every pound of his mass into the wood without pausing to blink.”
The realization hit Soma hard. In 2026, he was a senior project manager who dictated terms to massive building firms. In 1559, he was just high-value inventory.
He looked down at his own chest. A dark, wet handprint was smeared right across his new indigo silk robe. It was a clear mark. Nobunaga had just shown him that while modern math could control the timber and the trenches, his actual life belonged to a man who saw no difference between a human neck and a piece of scrap wood.
A slight scuffle of bare feet against the dirt broke his concentration.
Tokichiro stepped out from the corner shadows. The small peasant checked the body, then looked up at Soma with a sharp, calculating focus. The raw violence hadn’t slowed him down; it just confirmed the rules of the site they were running.
“Builder,” Tokichiro whispered, his voice low in the damp air. “The Warlord is clear of the yard. Are we still on track?”
Soma took a slow breath, swallowing down the copper taste of the air. He forced his face back into a cold, flat mask. “The spy is dead,” he said, pulling his indigo sleeve straight to steady his posture. “The leak is plugged. Let’s get back to the line.”
He didn’t wait for the peasant to move. Soma reached out, shoved the heavy cedar door aside himself, and stepped back out into the sweltering mud of the perimeter.
The rhythm of the perimeter was entirely gone. The heavy rasp of the crosscut saws and the steady thud of cutting tools had stopped completely. As Soma and Tokichiro walked back toward the worksite, they found the entire carpenter guild and the laborers standing in a thick, silent cluster near the main workbenches.
The labor rotation had hit a total standstill.
The men were shifting their weight in the muck, their knuckles white as they gripped the handles of their heavy iron tools. They had heard the high, agonizing scream echoing from the supply sheds. They didn’t know what the pale builder had done to the quiet worker with the blue hands, but the raw noise had terrified the workers and set the hardened guild on edge.
Genjo, the massive carpenter chief, shoved his way to the front of the pack. His thick, scarred arms were crossed tight over his chest. He stared at Soma, his dark eyes dropping instantly to the wet, crimson handprint smeared right across the center of the engineer’s blue silk robe. Genjo’s heavy jaw went rigid, his usual blunt arrogance completely disappearing at the sight of the blood.
“The saws are quiet, Builder,” Genjo growled, his rough voice carrying a thick layer of caution. He didn’t spit this time; he kept his distance. “We heard him scream in the shed. My crew is asking questions about the ground we’re standing on. What happened to the hauler?”
“The laborer was a Saito spy,” Soma announced, his voice flat and loud enough to carry across the entire, silent yard. He didn’t flinch, forcing his face to stay level to mask the nausea still twisting his gut. “He was the one cutting the timber to rot your wall from the inside out.”
A sharp intake of breath went through the ranks of the carpenters. The workers exchanged panicked looks, the reality of a covert saboteur working right next to them in the mud hitting the guild like a physical blow.
“The spy is dead,” Soma continued, his tone brutally direct. He let the words hang in the damp air to make sure every man understood the timeline. He took a step forward, moving right into Genjo’s space. He didn’t have Nobunaga’s massive frame, but he used the Warlord’s authority like a heavy iron ram. “The leak is plugged. The threat is off this line.”
Genjo stared at the blood on the indigo silk, then looked up into Soma’s steady eyes. The chief swallowed hard, the last of his working-class defiance completely breaking under the unyielding logic of the situation.
“If those saws stay quiet for too long, I’m going to assume this entire crew was part of the sabotage,” Soma said, his voice dropping into a quiet, flat cadence. “Get back to the rotation right now, or Lord Nobunaga is going to audit this entire line again personally. And he won’t be using blue dye to find the traitors. He’ll use his blade.”
The warning hit the mark. The carpenters didn’t utter a single word of protest. Under Genjo’s frantic, barked orders, the men scattered, diving back toward the timber. The rhythmic sound of saws and cutting tools filled the air again.
Soma turned to Tokichiro, keeping his voice low so the guild wouldn’t catch the slight edge returning to his breath.
“You’re the foreman,” Soma said, shifting his weight in the mud. “Make sure every joint is cut exactly to the standardized stick. Don’t let them rush the cuts just because they’re scared.”
“I’ll hold the line, Gishi-sama,” Tokichiro vowed, his sharp eyes flicking to the bloody handprint before checking Soma’s face. “Where are you heading?”
“Back to my quarters,” Soma replied, turning slowly away from the perimeter. “I need to clear my head. Keep the productivity moving until sundown.”
The heavy, sucking mud of the western palisade finally gave way to the packed dirt and stone pathways of the inner castle. Soma didn’t take the fastest route back to his room.
His feet moved automatically, putting distance between himself and the sound of the crosscut saws, but his thoughts were stuck on the floor of the shed. He found his sandals dragging across the heavy planks of a narrow wooden bridge. The structure spanned a fast-moving branch of the Kiso River that split the western worksites from the inner keeps of the fortress.
The morning mist was thinning under the sun, but the air was still a sweltering, damp weight that made the heavy silk stick to his back. Soma pulled up dead in the center of the span. He braced his good left hand against the rough timber railing, his knuckles turning stark white as he leaned over the running water.
He hinged forward, gripping the bridge railing and staring down into the gray river slamming into the stone pylons below. The constant roar of the water swallowed the rest of the castle, blocking out the noise of the yard.
“Get a grip,” Soma whispered, his voice cracking. He shut his eyes, leaning his head hard against the wood. “The leak is plugged. It’s just a change on the ground. Deal with it.”
The composure he had used on the carpenter crew was completely gone.
The weight of the execution was finally hitting his system. He’d just seen a man’s hand get nailed to a beam. He could still hear that wet, dying rattle from the floor of the shed. It was a brutal piece of reality that his mind couldn’t clear away.
Soma looked down at his chest. The new indigo silk was completely shot. Right over his sternum, right where his pulse was hammering, was the dark smear of Nobunaga’s bloody hand. The stain had dried into the cotton, turning the blue fabric into a stiff, dark crust that smelled like raw metal.
It was a brand. Blueprints and math didn’t make him a partner; they just made him a tool owned by a man who broke lives like dry twigs.
The damp wind off the river didn’t cool him down; it just made the flush on his neck burn hotter. He tried to control his breathing, but his discipline was entirely spent. As his eyes tracked the swirling currents below, the gray water dragged his consciousness right back to the bank of the Kiso.
The memory cut in like a knife.
The cold hit his chest like a steel beam, driving the air from his lungs as black water and mud flooded his throat. He remembered the rapids tumbling him end over end, his limbs pinned to his ribs, until the roar turned into a sharp, metallic ringing inside his skull.
Then came the grip. A hand locked onto his collar with crushing force, yanking his waterlogged weight straight out of the current.
He remembered hitting the gravel, retching up the river silt, and the sudden block of heat that closed over him as a massive figure stepped into the freezing wind. He had blinked through grit and stinging mist.
Kneeling over him was a broad-shouldered silhouette. The face was a total blur in his disoriented state, but he could see a mass of wet, unkempt, messy hair shaking in the fog.
A rough, calloused thumb had brushed the hair from his eyes. The touch was heavy, and the words were low.
“I gotcha... yer safe now...”
Then a sharp clack of iron on stone vibrated through the gravel.
He leaned over the wooden rail, staring down into the churning gray water smashing against the stone pillars below. The roar of the river cut through everything, drowning out the waking noises of the castle yard.
“Focus,” Soma muttered to the empty air, his voice rough and shaking. He clamped his eyes shut, pressing his forehead against the cold wood of the railing. “The threat is down. It’s just a variable change. Figure out the next step.”
He slammed his left fisted hand hard against the timber rail, letting the dull ache ground him. He reached up with shaking fingers, hovering right over the stain without touching the stiff cloth.
The muggy wind coming off the water hit his face, making the flush on his skin feel even hotter. He tried to count his breaths to get a grip on his thoughts, but the mental wall he usually relied on was completely cracked. The panic was flooding in, ignoring every rule he had.
He didn’t just want the quiet safety of Tokyo; his whole body ached for it.
He thought of their apartment, the cramped, quiet place he and Haruka had shared ever since their parents passed away. After the funeral, that small space had been the only real anchor they had left.
He could picture her sitting on the floor of their living room, surrounded by colored pencils, pattern drafts, and heavy linen swatches from her job at the fashion design company, muttering about production deadlines. At the same time, her cup of espresso went cold on the low table.
“What would you even say to me right now, Haruka?” Soma asked the rushing water, his voice cracking in the quiet of the span. “My math doesn’t work here. The time period is built on blood.”
In his world, his value was a fact. He remembered the boardroom presentations, the senior partners nodding along because his structural load calculations were flawless. That was how you measured a successful life. Out here, none of those metrics meant a thing.
He hinged forward, gripping the bridge railing and staring down into the gray river slamming into the stone pylons below. The constant roar of the water swallowed the rest of the castle town, blocking out the noise of the yard.
Here, leaning against a rough wooden railing in 1559, none of that mattered.
He ground his teeth together, his chest heaving under the restrictive wrap of the ruined indigo silk. He was paralyzed by the realization that the next time he miscalculated, Nobunaga wouldn’t just press a bloody hand to his chest; he would drive a blade through his neck.
Soma let out a deep, ragged sigh. It was a heavy exhalation of total exhaustion and raw fear that quickly dissipated over the rushing water.
The moment of emotional failure had to end. He could not afford to shatter here. The stoicism had to be violently rebuilt.
He reached across his chest with pale, trembling hands, his fingers gripping the lapels of the ruined Aizome indigo silk. He pulled the kosode tight across his torso. The mechanical friction of the movement caused the crusty, dried blood of the Warlord’s handprint to crack and flake against his sternum.
He turned sharply away from the wooden railing and began to walk. His gait was incredibly rigid; with every calculated step he took back toward the guest quarters, he kept his eyes locked straight ahead, treating the castle grounds strictly as a grid of distance and time to be conquered, entirely shutting down his peripheral awareness. He did not look back at the water.
High above the inner courtyards, partially obscured by the thick, rolling morning fog, the high balcony of the Kiyosu Keep offered an unobstructed vertical view of the river branch.
Oda Nobunaga stood at the absolute edge of the polished cedar deck. He wore his dark gray silks, the heavy fabric hanging loosely over his massive, heavily scarred chest.
The humid morning wind whipped aggressively across the elevated platform, but it did not seem to affect the Demon King. He radiated a furnace-like intensity that actively pushed the heavy mist away from his broad shoulders. His bare feet gripped the wooden planks, his stance as immovable as a load-bearing pillar.
Nobunaga’s gold-flecked eyes were narrow and dilated, fixed entirely on the small, indigo-clad figure retreating from the bridge far below. The Warlord’s thick, leather-rough hands gripped the wooden railing of the balcony. The heat transferring from his calloused palms was so intense it seemed to bake the damp wood beneath his fingers. He had seen the entire sequence.
He had seen the Ghost’s pale hands grip the bridge. He had seen the violent shiver that racked the modern man’s frame, and he had watched the heavy, exhausted sigh.
SCUFF.
A faint scuffle of straw sandals sounded behind the Warlord. Toichi, the scarred senior retainer, stepped onto the balcony and immediately dropped to his knees, pressing his forehead hard against the warm floorboards.
“My Lord,” Toichi rasped, his gravelly voice cutting through the hum of the wind. “The Honored Guest lingers dangerously close to the deep currents of the river. Do you require a detail of guards to secure him? He looks as though his mind is breaking.”
Nobunaga did not turn his head. He kept his predatory gaze locked on the empty bridge below, watching the exact spot where Soma had just stood.
“I do not require guards to tether a man who has nowhere to run, Toichi,” Nobunaga commanded, his voice a low, heavy vibration that traveled heavily through the cedar deck. “He looks at the water as if it will carry him back to the world of ghosts. But his feet remain planted firmly in my mud.”
“He is soft, My Lord,” Toichi warned, keeping his head bowed respectfully against the wood. “I watched him from the lower wall. He shivered like a beaten dog in the wind. The carpenter guild bows to his math, but his flesh is undeniably weak. The blood spilled in the supply shed disturbed him deeply. If the terror overtakes his mind, he may throw himself into the current to escape the pressure.”
Nobunaga let out a dark, resonant hum of amusement. He squeezed the cedar railing, his heavy, dense muscles bunching under the dark gray silk.
He did not shatter, Nobunaga thought, a dark thrill of absolute possession echoing in his chest. I branded him with the blood of a Saito enemy, and he bore the weight.
“His stomach held, Toichi. He did not vomit when I drove the iron through the spy’s palm. He did not turn away when the artery was severed,” Nobunaga corrected smoothly. “He merely realized the absolute weight of his own logic.”
Nobunaga knew the Ghost wouldn’t jump. He had seen the desperate, survival-driven math calculating in the engineer’s eyes.
“He wears the blood of my enemies on his chest,” Nobunaga growled, his dominating presence rolling over Toichi in a suffocating wave. “It marks him as property of the Oda. The water gave him to me, Toichi. I am aware of his fragility, but I have absolutely no intention of letting the river take him back.”
