The Two Forts
Location: Audience Hall, Kiyosu Castle
Current Date/Time: Noon. Early Autumn, 1559
The midday heat of early autumn pressed into the audience hall of Kiyosu Castle, but the sweat soaking through the silk and cotton robes of the Oda retainers had nothing to do with the weather.
Chaos had consumed the chamber.
The rigid discipline that usually governed the high council had shattered the moment the scout screamed the number thirty thousand. Men who had spent their lives holding the bloody borders of Owari were now shouting over one another, their voices cracking with raw panic. Hands gripped nervously at the hilts of swords. Knees shifted restlessly against the tatami. The air was thick with the sharp, sour stench of fear.
Oda Nobunaga sat on the raised cedar dais, completely still.
He did not shout for order. He did not move to soothe his men. He simply watched his highest-ranking generals unmask themselves. His heavy, golden-flecked gaze swept over the thrashing room, dissecting the cowardice, before drifting past the veteran commanders to the very back of the hall.
There, kneeling in the lowest seat near the open veranda, sat the Fushingashira.
While the samurai around him debated surrender and mountain retreats, Soma was a stone in a rushing river. He sat perfectly upright, his hands resting flat on his thighs, his eyes fixed on the floorboards. He wasn’t panicking. He was calculating.
Nobunaga’s jaw tightened. He had seen enough.
The warlord reached to his left. His large hand closed around the black-lacquered scabbard of his katana resting on the sword stand. Without a word, Nobunaga lifted the heavy weapon and drove the iron-capped end of the scabbard down into the cedar floorboards.
The sound cracked like a musket shot, echoing violently off the wooden rafters.
The shouting died instantly. The retainers froze in place, the sudden, deafening silence ringing in their ears. Every man in the room snapped their attention to the dais, bowing their heads as they met the cold, terrifying ridicule burning in their Lord’s eyes.
“Fools,” Nobunaga spat, his deep baritone lethal and quiet. “Cowards. If the Lord of Suruga were marching tomorrow, every single one of you would have already handed him the keys to Owari.”
The words cut through the room like a drawn blade.
“A thousand apologies, My Lord!” a chorus of terrified voices mumbled into the tatami mats.
Soma remained still, keeping his head bowed in the back row, refusing to draw attention.
Nobunaga leaned forward, resting his forearms against his thighs. “Katsuie. Nagahide. Hidesada. You are the pillars of this clan. Tell me how my pillars intend to hold up the roof against thirty thousand men.”
Shibata Katsuie swallowed hard, the scars on his face pulling tight. “My Lord. We must order a mass conscription. Every farmer who can hold a bamboo spear. We meet them on the plains and bleed them for every inch of Owari dirt.”
Niwa Nagahide shook his head sharply. “Suicide. We cannot out-bleed the Imagawa. We must pull all forces back into Kiyosu, reinforce the gates, and wait out a siege. We let them starve.”
Hayashi Hidesada, pale and sweating, pressed his forehead to the mat. “My Lord... a siege will only delay the inevitable. If we send envoys now, before blood is drawn... we may be able to negotiate a surrender that leaves your head on your shoulders.”
Nobunaga didn’t react. He lifted a hand, snapping his fingers.
A trembling attendant hurried forward from the shadows, carrying a ceramic jug of sake and a shallow, red lacquer sakazuki cup. The boy poured the clear liquid, bowing low before scrambling backward.
Nobunaga picked up the red cup with one hand, his other still resting lightly on the hilt of his katana. He drank the sake in a single, slow swallow. He lowered the cup.
“No,” Nobunaga said. The word was flat, deep, and absolutely final.
The three generals stared at him, their mouths slightly parted in shock.
“But My Lord,” Shibata grunted, his face darkening with frustration as he prepared to repeat his petition for a glorious charge. “If we do not—”
Nobunaga casually opened his fingers.
The red lacquer cup hit the edge of the wooden dais and shattered. The sharp crunch of the breaking lacquer severed Shibata’s sentence immediately.
Nobunaga ignored the shards. He looked past his three most powerful retainers, his gaze locking onto the stoic figure kneeling in the shadows of the open veranda.
“Fushingashira.”
Soma stiffened. Slowly, he lifted his head, his dark eyes meeting the warlord’s from across the length of the hall. He placed his palms on the mat and bowed smoothly. “What does the Lord of Owari wish?”
At the front of the room, Shibata, Niwa, and Hayashi turned their heads, staring in disbelief at the man in the back row.
“Come to the front,” Nobunaga commanded.
Whispers rippled through the hall. It was a gross breach of protocol. A man with no birthright, a mere builder, was being summoned to sit among the highest-ranking samurai in the clan during a council meeting. Nobunaga didn’t care. He waved his hand, silently demanding obedience.
Soma stood. He kept his posture rigid, feeling the burning glares of the veteran retainers tracking his every step as he walked down the wide, empty aisle. The rustle of his clothes seemed impossibly loud.
When he reached the front, he dropped to his knees, settling onto the tatami beside the three generals.
Shibata Katsuie let out a toxic, vibrating grunt of disgust, shifting his weight away from the outsider.
Nobunaga leaned over his armrest, looking down at Soma. “My generals offer me suicide, starvation, or submission. What is your recommendation, Ghost?”
Soma kept his eyes leveled on the wooden base of the dais. “My Lord. I am no military general. I am just your head of construction.”
It was a careful, calculated deflection. Soma knew the political danger of sitting at this level. If he spoke out of turn, he would infuriate men who could easily have him assassinated in his sleep.
Nobunaga saw right through the evasion. A dark, amused gleam entered the warlord’s eyes. He wanted to chastise his veterans, and he was going to use his favorite tool to do it.
“Let us pretend, then,” Nobunaga drawled softly. “Let us say you are a general. What will you do?”
Soma stared at the weave of the tatami, his mind racing.
He was a time traveler, yes, but he was a civil engineer, not a historian. His genius was rooted in spatial reasoning, structural mathematics, and applied physics, not a photographic recall of a high school Nihonshi (Japanese history) curriculum he had crammed for nearly a decade ago.
His memory of the Sengoku Jidai was hazy, limited to the macro-level pop culture every Japanese citizen knew: Nobunaga wins at Okehazama in a storm. Nobunaga dies in the fires of Honno-ji in 1582. Nobunaga uses matchlocks.
Okehazama, Soma thought frantically. He wins at Okehazama.
But he couldn’t say that. Suggesting they march to a random gorge called Okehazama right now would sound entirely unhinged. The significance of that specific valley wouldn’t materialize until Imagawa Yoshimoto actually decided to camp there. If Soma spoke of the future too clearly, they would write him off as a lunatic, or worse, a spy.
The silence in the chamber stretched. The soft breeze of early autumn brushed against the paper screens. Nobunaga simply watched him, waiting.
Soma closed his eyes. He stopped trying to remember dates and clan names. He forced his mind to do what it did best. He remembered topography. He remembered the ruins he had studied in university when analyzing ancient load-bearing foundations.
He remembered the southern border. The mud forts of Odaka and Narumi that were currently occupied by Imagawa sympathizers.
Soma took a slow, deep breath and opened his eyes.
“My Lord,” Soma said quietly. “May I have a look at the map of Aichi Prefecture?”
Nobunaga tilted his head, a flicker of genuine confusion crossing his sharp features. “Aichi? Prefecture?”
Soma’s stomach dropped. Idiot.
He coughed, quickly masking the slip. “Forgive me, My Lord. A slip of the tongue. The map of Owari.”
Nobunaga stared at him for a second longer before raising two fingers. An attendant scurried out, returning moments later with a low cedar table, placing it directly in front of Soma. A second attendant unrolled a large, faded map made of heavy parchment, securing the edges with iron paperweights.
Soma leaned forward.
The map was disorienting. The topography was vaguely familiar, but the kanji (Chinese characters) were written in archaic, looping brushstrokes that made his modern eyes ache. Still, he traced the jagged lines of the southern border. His index finger ghosted over the coastal plains until he found the characters for the Odaka and Narumi fortresses.
“Well, Fushingashira?” Nobunaga prompted, his voice echoing in the quiet room. “The assembly is waiting for you.”
Soma stared at the ink. He was waiting for one of the veterans to see it. It was basic logistics. But as the seconds ticked by, no one spoke. They were too blinded by the terror of thirty thousand men to see the mechanics of how an army that size actually moved.
Hayashi scoffed softly from his left. “It seems even the Fushingashira is having difficulty solving a problem that cannot be fixed with a hammer.”
Niwa Nagahide bowed his head toward the dais. “My Lord. I think it is best to end the assembly and let your subjects think on—”
Soma didn’t let him finish.
He slammed his right index finger down onto the parchment. He pressed so hard the heavy paper audibly crumpled beneath his nail.
“Here,” Soma said, his voice ringing with sudden, absolute authority.
He dragged his finger to a clearing roughly five hundred meters away from the Odaka fortress, then tapped another spot near Narumi.
“We do not need to fight thirty thousand men today,” Soma said, looking up to meet Nobunaga’s eyes. “We need to starve their vanguard. Odaka and Narumi are the Imagawa’s footholds in our territory. We need to build two forts right here. Washizu and Marune.”
Shibata Katsuie erupted. “Are you mad?!” The burly general slammed his fist into the floorboards. “My Lord, the Fushingashira is making a fatal mistake! That area is directly on the Mikawa border! If you send men to build forts there, the Imagawa vanguard will slaughter the laborers before the first post is driven into the mud!”
Nobunaga didn’t look at Shibata. He kept his eyes locked on Soma, a dark, thrilling realization beginning to pull at the corners of his mouth.
“Well, Fushingashira?” Nobunaga asked softly. “How do you answer my general?”
“Laborers have hands, General Shibata,” Soma answered without looking away from Nobunaga. “When they are not holding hammers, they can hold spears. The forts will act as a physical blockade, cutting off all supply lines to Odaka. It will force the Imagawa to either starve, or divert their army into a narrow, muddy supply route to relieve their men.”
Soma took his finger off the map. “We choke their throat before they can even draw their sword.”
Nobunaga stared at the crumpled paper where Soma had pressed his finger. The strategy was aggressive, insulting, and brilliant. It turned Owari’s weakness into a jagged edge.
A slow, terrifying smirk spread across the Demon King’s face.
“Well done,” Nobunaga murmured, the satisfaction in his voice chilling the room. “I approve the construction. Draft the plans for the forts immediately.”
Shibata’s face turned a bruised, ugly red. “My Lord, this is preposterous! Building fortifications directly on their border is an open provocation! It will be a direct intimidation to the Lord of Suruga!”
Nobunaga’s smirk vanished.
The warlord snapped his head toward Shibata. The temperature in the room seemed to plummet. Nobunaga’s eyes went completely dead, radiating a killing intent so pure and heavy that it physically pushed the air out of the general’s lungs.
“You dare disobey my orders, Katsuie?” Nobunaga whispered. His hand drifted back to the hilt of his katana.
Shibata’s blood ran cold. The veteran warrior threw himself forward, slamming his forehead against the tatami so hard the floorboards groaned. “Forgive me, My Lord! I overstepped! It will be done as you command!”
Nobunaga stared at the prostrating general for a long, suffocating moment, letting the terror fully saturate the man’s bones.
Then, Nobunaga released the hilt of his sword.
“Dismissed,” Nobunaga barked, his voice echoing through the silent hall. “Get out.”
The retainers didn’t hesitate. Samurai scrambled to their feet, bowing hastily before retreating toward the outer verandas, desperate to escape the oppressive heat of the warlord’s presence.
Soma stood up with them. He bowed perfectly to the dais, then turned and joined the exodus, filing out behind the muttering, shaken generals.
Nobunaga remained on the dais, motionless.
He didn’t look at the map, and he didn’t look at his fleeing veterans. The warlord’s dark, heavy gaze tracked the Fushingashira as he walked down the aisle. Nobunaga watched the steady, unbroken line of Soma’s shoulders, his eyes lingering in the shadows of the doorway, staring long after the last sliver of fabric had disappeared from view.
