Chapter 10: Supply and Demand
Dawn crept through the filthy, soot-stained cracks in the workshop's windows, finding Tetsuya already wide awake and aggressively hammering a thick piece of salvaged plywood over his splintered front doorframe.
He had a stubby pencil tucked behind his ear and a deep, angry scowl on his scarred face as he mentally calculated the overhead. Each heavy iron nail cost exactly 5 Ryo. The thick plywood was 300 Ryo, dragged out of a construction site dumpster three blocks away in the dead of night. The cheap black marker he used to write the word "DOOR" in massive, ugly block letters across the wood was 25 Ryo.
Total door repair: 350 Ryo.
A real, brand-new solid oak door from Sato the carpenter would cost 2,300 Ryo.
Money saved: 1,950 Ryo.
Tetsuya gave the very last nail a solid, ringing whack with his hammer, stepped back, and crossed his arms to judge his handiwork. It was hideously ugly. It looked like the entrance to an abandoned crack house. But it kept the morning rain out, it blocked the wind, and it successfully fulfilled the absolute basic mechanical definition of a door. The giant word "DOOR" written in permanent marker was technically unnecessary, but Tetsuya found it deeply, personally satisfying. It was a giant middle finger to Ryu's thugs.
He wiped the grease and sweat from his forehead with the back of his hand, leaving a dark smudge of dirt across his pale skin. The familiar System notification pulsed gently in the upper corner of his vision.

"This glowing parasite always has to be so damn dramatic," he muttered, turning his back on the plywood and walking deeper into the shop.
He stepped over the still-messy remains of last night's confrontation. Shards of broken display glass crunched loudly under his heavy steel-toed boots. He walked over to his workbench, picked up a chipped ceramic teacup, and took a sip. The green tea was completely ice-cold and tasted like liquid pennies, but he drank it anyway. Wasting tea was wasting money.
"Sending an idiot to break my hands," Tetsuya grumbled to himself, setting the cup down. "Amateur move, Ryu. All that money and not a single working brain cell."
He leaned heavily against his wooden workbench, his dark eyes narrowing as he thought through the overarching problem. Breaking Ryu's expensive shop windows wouldn't solve anything. Paying street thugs to jump Ryu in an alley wouldn't solve anything either. That was child's play. It was loud, illegal, and bad for business.
If you really wanted to put a merchant in the dirt, you didn't break his bones. You broke his profit margins.
Tetsuya's intense gaze drifted to the strange, ugly mechanical contraption sitting on the center of his workbench. He had spent the entire night building it instead of sleeping, fueled purely by old-man spite, cold tea, and the desperation of poverty.
It looked like a bizarre Frankenstein monster of metallurgy. It resembled a thick metal drum equipped with a heavy hand-crank on the side, a wide iron hopper welded to the top, and two separate output chutes bolted to the bottom. Thick copper coils, salvaged magnets from broken generators, and interlocking gears were completely visible through the crude gaps in the housing.
It wasn't pretty. The edges were sharp and rough, the forge-welded seams were incredibly ugly, and one side had "Property of Tetsuya" violently scratched deep into the metal with a steel nail.

[Operational Efficiency: 87.4%]
[Durability Rating: 72%]
"Good enough to get paid," Tetsuya grunted, grabbing the heavy machine by its crude handles. It weighed easily thirty kilos, and his skinny, underfed teenage arms strained and shook with the intense effort. He carefully wrapped the contraption in a thick, old burlap sack and tied it tight with coarse twine.
War wasn't about who had the biggest, sharpest sword. War was about who controlled the iron mines.
The massive scavenger camp sprawled across the far eastern outskirts of Konoha like a massive, untidy, festering wound.
It was the absolute underbelly of the ninja village. Stacks of rusted metal, towering piles of broken military weapons, and mountains of unprocessed ore created a labyrinth of tetanus waiting to happen. The air out here was thick and heavy, smelling strongly of oxidized rust, unwashed sweat, and the cheap, blinding rice wine the workers chugged to forget that they spent their entire lives digging through the village's garbage.
Tetsuya trudged through the muddy camp, the heavy burlap-wrapped machine bouncing painfully against his spine with each step.
His face, naturally set in its terrifying, deadpan serial-killer scowl, caused the hardened adult workers to instinctively step aside and give him a wide berth. Several of the heavily tattooed scavengers recognized him and started whispering loudly to each other.
"Hey, that's the slum blacksmith."
"The scrawny kid Ryu wants completely blacklisted?"
"I heard he folded Ganzu the Smasher like a lawn chair last night. Broke his whole arm."
"Boss Jin said we ain't supposed to do no deals with him..."
Tetsuya completely ignored the whispers. He kept walking with the heavy, unbothered stride of a man who belonged in the industrial dirt, pushing past the rusted carts until he reached the central clearing.
Sitting on what could only be described as a makeshift throne welded entirely from broken swords and scrap metal, was a massive, heavily scarred man. Boss Jin. The undisputed king of the gray market.
Jin was casually chewing on a splintered toothpick, his massive, muscular shoulders hunched forward as he sorted through a filthy paper ledger. The two fingers missing from his left hand didn't seem to hinder his page-turning at all.
"Tetsuya," Jin's voice rumbled, sounding like gravel tumbling in an empty cement mixer. He didn't look up from his ledger. "Word on the block is you had some serious excitement last night. Door get broke?"
"Something like that," Tetsuya replied casually. He dropped his heavy burlap bundle onto the dirt with a loud, metallic clank. "I need to talk business."
Jin finally looked up. He casually gestured with his chin at the six massive thugs who had quietly, aggressively positioned themselves in a tight circle around Tetsuya. They all carried nasty-looking makeshift weapons—rusted lead pipes, heavy sledgehammers, and a particularly bloody-looking meat hook.
"Business is exactly what we need to discuss, kid," Jin said, spitting his toothpick onto the dirt. "See, I got a very polite message from Ryu yesterday evening. Says anyone caught selling raw iron to you is gonna find themselves permanently cut off from the Emporium's payroll. Says you're bad for the local economy."
Tetsuya didn't even glance at the armed thugs surrounding him. He kept his dark, dead eyes locked directly on Jin, his scarred face a perfect mask of absolute boredom.
"Let's cut the nonsense, Jin. How much does Ryu pay you per kilo of unsorted scrap iron?" Tetsuya asked, his voice echoing flatly in the clearing.
Jin's thick eyebrow raised slightly at the kid's total lack of fear. "Five Ryo a kilo. Been that way for five years."
Tetsuya nodded slowly, as if this confirmed something deeply tragic. "And how much of that unsorted trash is actual, pure chakra steel? The blue stuff. The military-grade material."
Jin shrugged his massive shoulders. "Maybe ten percent on a really good day. The rest is just dirt, heavy rust, and cheap pig iron. Why do you care, kid?"
Tetsuya crouched down in the dirt and began untying the thick twine around his bundle. "Because I'm about to pay you twenty Ryo per kilo. But I'm only paying for the pure, unadulterated chakra steel dust. And I brought the tool to help you get it."
The crowd of scavengers around Tetsuya had massively grown. Word traveled insanely fast in a slum community where violence and gossip were the only forms of free entertainment.
Nearly forty filthy, hardened scavengers now watched in total silence as Tetsuya set up his ugly, strange mechanical contraption on a flat piece of compacted dirt.
"What the hell is that ugly thing?" Jin asked, leaning forward on his scrap-metal throne, genuinely curious.
"It's a Resonance Sifter," Tetsuya replied, expertly adjusting a heavy copper gear on the side of the drum. "Have one of your men bring me a bucket of your absolute worst scrap. The bottom-of-the-barrel garbage. The stuff Ryu would barely give you two Ryo for."
Jin snapped his thick fingers. One of his thugs immediately ran off and returned lugging a rusted metal bucket filled with what looked like pure dirt mixed with tiny, useless fragments of broken iron and shattered kunai. It was the dregs—the useless filler they usually had to hide at the bottom of the carts just to get rid of it.
"This is straight-up garbage, kid," Jin said, crossing his arms. "Ryu pays half-price for this trash, and he complains the whole time."
Tetsuya nodded. "Perfect."
He effortlessly dumped the entire bucket of dirt and rusted metal into the wide iron hopper at the top of his machine. The crowd of scavengers murmured loudly, clearly thinking the kid was completely out of his mind. Tetsuya positioned two empty wooden buckets directly beneath the output chutes at the bottom, then grabbed the heavy iron hand-crank on the side.
"Pay attention," Tetsuya ordered, beginning to turn the crank with steady, rhythmic force. "Every single ninja weapon used in this village contains trace amounts of chakra steel. Even the cheap, broken ones. When you expose raw chakra steel to a rapidly shifting magnetic field..."
The ugly machine suddenly roared to life with an unholy, grinding racket. It rattled violently, squeaked loudly, and emitted a high-pitched, vibrating whine that made several of the tough street thugs wince and cover their ears. A faint, mesmerizing blue electrical glow began to emanate from the copper coils inside the drum as it spun faster and faster.
"...it resonates at a completely different frequency than regular iron or dirt!" Tetsuya yelled, having to raise his raspy voice over the deafening mechanical noise. "The magnets catch it, and the centrifuge separates it!"
The first output chute suddenly clicked open. It began to rapidly spit a thick, continuous stream of dull, useless gray powder and dirt into the left bucket. Slag. Rust. Total impurities. Absolutely worthless.
Then, the second chute activated with a loud clack.
From the right chute poured a fine, incredibly heavy, shimmering blue-black dust. It caught the afternoon sunlight, sparkling like powdered, highly lethal silver. Pure, military-grade chakra steel, violently separated from the rust and reduced to its most basic, raw form. It was ready to be instantly melted down and reforged.
The entire crowd of loud scavengers fell completely, stunningly silent. You could have heard a pin drop over the whining of the machine.
Jin slowly stood up from his metal throne. He walked over to the right bucket, his eyes wide. He reached in and grabbed a heavy handful of the blue-black dust, watching the pure chakra steel slip smoothly through his callused fingers like silver sand.
The gears in the mob boss's head were spinning almost as fast as the machine. If his men didn't have to spend weeks painstakingly hand-sorting rust from iron... if they could just dump it all in a hopper and extract the pure gold...
"How much for the machine, kid?" Jin asked, his gruff voice tight with absolute, naked greed. "Name your price."
Tetsuya's scarred lips curved into a sharp, uncompromising line.
"It isn't for sale, Jin," Tetsuya said quietly, letting go of the crank. "It's for lease. I own the technology. You operate it. But we do this strictly on my terms."
He reached into his dusty apron, pulled out a crumpled piece of paper, and smoothed it out on his knee. "I've already drafted the contract."
Jin snatched the paper, squinting hard at Tetsuya's cramped, highly technical handwriting. His lips moved slightly as he read the terms.
"Wait a damn minute," Jin said after a minute, looking up. "You want a hundred percent of the refined chakra steel output? Exclusively?"
"That is exactly right," Tetsuya nodded, keeping his face deadpan. "I pay you twenty Ryo per kilo of the refined blue dust. That is four times what that fat bastard Ryu pays you for raw scrap, and it is guaranteed cash on delivery. No haggling, no 'quality inspection' disputes, no nonsense."
Jin looked highly skeptical. "And what the hell am I supposed to do with the leftover slag? The gray powder?"
Tetsuya leaned forward slightly, his dark eyes locking onto Jin's. "You sell it to Ryu."
"The worthless stuff?" Jin blinked. "You want me to sell him literal dirt?"
"At three times the current market price," Tetsuya added, a dark smirk finally breaking through his scowl. "You tell him there's a massive shortage out in the field. Supply chain issues. Rising labor costs. Ninja interference. Whatever sad story makes sense. You squeeze him."
Jin looked back and forth between the contract in his hand and the scrawny teenager sitting on the dirt. A slow, deeply malicious understanding dawned on the gang leader's weathered face.
"You aren't just trying to beat his prices," Jin whispered. "You're trying to starve him out."
"I'm just changing the rules of the game," Tetsuya grunted, his face deadpan. "Ryu has been robbing you blind for five years, handing you literal pennies. I'm just making sure you finally get paid what your labor is actually worth, while planting my boot firmly on that fat bastard's neck."
Jin barked a loud, echoing laugh that startled his thugs. "By choking his supply line with literal garbage."
"While ensuring you make more money this month than you did all last year," Tetsuya pointed out logically.
Jin studied the contract again, then looked down at the ugly Resonance Sifter, still humming quietly with residual energy. The little pile of pure chakra steel dust gleamed beautifully in the sunlight. It was a literal money printer.
"What if I just take this machine right now, beat your ass, and tell you to get lost?" Jin asked, his voice suddenly dropping low and incredibly dangerous. The six thugs holding weapons immediately stepped closer, tightening the circle.
Tetsuya didn't even blink. He didn't reach for a weapon. He just stared right back.
"The magnetic calibration on those copper coils requires extremely precise monthly maintenance," Tetsuya stated, his voice completely flat. "Without it, the machine burns itself out and breaks down within three weeks. Plus, it needs a highly specific synthetic lubricant I formulated myself in my shop. You run out of that, the gears seize, the friction sparks, and the whole drum explodes like a bomb."
"And I suppose you're the only mechanic in this village who knows how to fix it?" Jin sneered.
"I'm the only one who knows how to build it," Tetsuya corrected, his voice ice-cold. "And I've got three more prototypes hidden around the village, along with heavily detailed schematics that go directly to the Military Police precinct if I happen to go missing today. You kill me, you kill the golden goose, Jin."
Tetsuya didn't flinch. He didn't break eye contact. He just sat in the dirt and stared at the massive, violent gang leader with the cold, dead eyes of a street hustler who had already calculated the exact cost of his own funeral and didn't care.
Jin stared back for a long, incredibly tense moment, actively searching for a single crack of fear in the scrawny kid's confidence.
Finding absolutely none, Jin threw his head back and burst out laughing.
"You've got iron balls, kid, I'll give you that!" Jin roared, stepping forward and clapping Tetsuya on the shoulder hard enough to make his teeth rattle. "Most grown men would be pissing their pants to walk in here making demands after Ryu put the hit out on them."
"I'm too broke to be scared, Jin," Tetsuya grunted, adjusting his dirty shirt and regaining his balance. "Panic doesn't pay the rent."
Jin grinned, revealing a row of yellowed teeth. "I like you, Tetsuya. You're a cold, calculating little bastard, but I respect that." He spat a wad of saliva into his massive palm and held his hand out. "We got a deal."
Tetsuya hesitated for only a fraction of a second. He spat into his own callused palm and firmly clasped Jin's massive hand. The handshake was bone-crushingly painful, but Tetsuya managed not to wince.
"I'll have three more machines delivered to this camp by the end of the week," Tetsuya said, standing up. "I expect your first heavy shipment of chakra steel dust delivered to my backdoor by Tuesday night."
Jin nodded, then turned to his heavily armed men. "You heard the man! Get this ugly machine set up in the main tent! We got real work to do!"
As the scavengers scrambled to follow orders, Jin leaned down close to Tetsuya's ear.
"Watch your back, kid," Jin warned quietly. "Ryu's gonna come for you again when he realizes what you did. And he ain't gonna send just one clumsy thug next time."
Tetsuya's eyes were cold and empty. "Let him. If that fat bastard wants to waste his cash on street goons instead of his business, that's his funeral. I'll just keep taking his customers."
Three days later, the upscale office of Ryu's Weapon Emporium resembled a violently kicked anthill.
"What the hell do you mean they're tripling the price?!" Ryu screamed, his face turning an alarming, splotchy shade of purple. He threw an expensive ceramic teacup against the wall, shattering it into pieces. "We have had the exact same arrangement with the Scrap Gang for five years!"
The shop's head accountant—a thin, highly nervous man with ink-stained fingers and terrible posture—flinched violently as if he had been physically struck.
"The scavengers are claiming there's a massive material shortage, sir," the accountant explained, his voice shaking barely above a whisper. "Boss Jin sent a message saying ninja activity has completely depleted the usual recovery sites. They claim they've had to send teams further out into dangerous territory, which drastically increases their labor costs..."
"I don't give a damn about their labor costs!" Ryu roared, slamming his fat fists onto his mahogany desk. "We monopolize the entire village! Go to the official Konoha Steelworks and buy our iron from them! Cut Jin off entirely!"
"We can't, sir! We've run the numbers!" the accountant pleaded, sweating profusely. "If we buy raw iron from the official village foundries, we have to pay full commercial retail price! If we do that, and then slash our store prices by fifty percent to compete with that slum blacksmith... we will be operating at a massive loss! Jin's cheap scrap yard was the only reason our profit margins were so incredibly high!"
Ryu froze, his chest heaving as the reality of the math hit him. He was trapped. "Fine. What about the quality of the scrap Jin is sending us?"
The accountant swallowed hard. "It's... it's literal dirt, sir. High silicon, massive impurities. The good metal is completely gone. Our blacksmiths downstairs are complaining that the iron is crumbling on the anvil."
Ryu closed his eyes, taking a deep, shuddering breath through his nose to keep from having a literal heart attack. When he finally opened them again, his hateful gaze drifted to the large glass window.
Down the street, clearly visible from his lavish second-floor office, was a line of people. Genin, heavily armed Chunin, and even a few elite Jonin. They were all waiting patiently in the sun outside a small, ramshackle building with a piece of ugly plywood that had "DOOR" written on it in black marker.
"How the hell is he doing it?" Ryu muttered, pressing his forehead against the cool glass. "His retail prices are a full twenty percent below ours. How is he making a profit with raw materials being this expensive?!"
The accountant nervously fidgeted with his wooden abacus. "Perhaps... perhaps the boy stockpiled supplies before the shortage hit the market?"
Ryu shook his head aggressively. "Impossible. That orphan was dead broke a week ago. He couldn't afford to stockpile a bag of rice."
Ryu turned away from the window, his expression hardening into pure, desperate malice. "Get the ledgers for the last three months. I want to personally review every single supplier and every single purchase."
"Yes, sir!" The accountant practically scurried out the door, incredibly relieved to escape the suffocating tension in the room.
Left entirely alone, Ryu walked over to his private liquor cabinet and poured himself a generous cup of imported rice wine with shaking hands. He downed it in one painful swallow.
This absolutely wasn't supposed to happen. The brat was supposed to be a minor, pathetic annoyance. A bug to be easily squashed by the bureaucracy. Not an existential threat to an empire that had ruthlessly dominated Konoha's weapon market for a decade.
The heavy oak door opened again, and Ryu's head blacksmith entered. The man's apron was covered in thick soot, and his expression was grim.
"Another batch completely failed, boss," the blacksmith reported without any preamble, tossing a shattered, brittle kunai onto Ryu's desk. "The steel from Jin won't take a proper edge. It's too soft in the middle and too brittle on the outside. It's literally like trying to forge with wet mud."
Ryu poured himself another full cup of wine. "Can we salvage any of it? Melt it down again?"
The blacksmith shook his head in disgust. "Not for ninja-grade weapons, sir. Maybe we can beat it into cheap farming tools for the civilian sector, but we can't sell this to Shinobi. It'll get them killed."
Ryu gestured dismissively with his hand, and the blacksmith departed, leaving the fat merchant completely alone with his dark, spiraling thoughts.
Outside his window, the long line at Tetsuya's ugly shop had grown even longer. The famous weapon specialist from Team Guy—the rich girl, Tenten—had just emerged from the plywood door, struggling to carry three heavily wrapped bundles of weapons, her face absolutely glowing with pure delight.
Ryu felt a cold, sickening sensation settle deep in the pit of his stomach. His supply chain was severely compromised, his production quality was in freefall, and his highest-paying customers were defecting in droves.
Ryu suddenly realized he wasn't fighting a foolish, arrogant blacksmith. He was fighting a genius street hustler who was rapidly cornering the entire block.
Back at the Iron Will Workshop, Tetsuya sat quietly behind his heavily cracked, glued-together wooden counter, rapidly counting the day's earnings.
The massive queue outside had finally dispersed as the sun went down, leaving him entirely alone with his thoughts and a heavy iron lockbox absolutely overflowing with crisp Ryo notes.
[QUEST PROGRESS: 37% COMPLETE]
[Ryu's Emporium Market Share: 63% (RAPIDLY DECLINING)]
[Iron Will Workshop Market Share: 22% (RISING)]
Not bad for three days of hard work, Tetsuya thought, the System notification hovering at the very edge of his vision like a satisfied, glowing cat.
But it wasn't enough. Not nearly enough. Ryu still had incredibly deep pockets, a massive emergency fund, and heavy political connections in the commerce department. This was just the opening salvo in what was going to be a protracted, brutal turf war.
Tetsuya's callused fingers paused on a particular coin in his box. It was heavier than the standard currency, gleaming brightly under his oil lamp. It had the official emblem of the Hokage stamped deeply onto one side.
It gave him an idea. A very ambitious, highly dangerous idea.
Jin and his filthy scavengers were handling the raw material side of the supply chain beautifully. The gray market was secured. But if Tetsuya truly wanted to put Ryu in the dirt and destroy him permanently, he needed to secure the absolute most valuable, untouchable market segment in the entire village.
He needed government contracts. Bulk orders for the regular military forces.
Tetsuya grabbed a piece of scrap paper and a stubby pencil. He didn't write a fancy, perfectly formatted letter. He just started crunching the raw numbers for a bulk military order, figuring out exactly how low he could drop his bulk pricing while still making a profit.
Outside in the chilly evening breeze, the ugly piece of plywood with "DOOR" written on it creaked loudly on its makeshift hinges. It was a hilarious symbol of practical, blue-collar frugality that had somehow become the Iron Will Workshop's most recognizable marketing feature.
Tetsuya smirked, tapping his pencil against the cracked wooden counter.
Ryu still thought this was just a pride fight over who made the sharpest throwing knives.
He was dead wrong. Out here on the streets, the guy with the best product didn't always win. The guy who controlled the supply line won. It was never just about the metal. It was about controlling the board.
And Tetsuya was about to take all of his pieces.
