Konohagakure no Sato:
Hokage Office :
The journey from the Sealing Corps headquarters to the Hokage Office was a blur for Vice-Captain Koga. He moved with a haste that belied his age, bypassing the usual chitchat of the administrative halls.
After a brief, impatient wait with the secretary, Koga was finally ushered into the inner sanctum.
Inside, the Third Hokage, Hiruzen Sarutobi, was entrenched in his eternal war against paperwork. Stacks of documents formed a fortress around him, and the God of Shinobi looked more like a tired accountant than a warrior.
As soon as Koga entered, Hiruzen looked up, a spark of relief in his eyes. He was always happy for a reason to slack off .
( Finally a break from paperwork )
Koga was one of perhaps 10 people in the entire village who could sit in this office not as a subordinate, but as a respected peer. He took the seat opposite the desk, but unlike his usual calm demeanor, Koga was vibrating with a strange, restless energy.
Koga sat in silence, staring at the grain of the wooden desk, trying to organize the chaos he had just witnessed into coherent sentences.
Hiruzen, seeing his old friend's unusual silence, felt his relief turn into mild confusion. He set down his pipe and speak to one of the only 5 Seal Grandmaster of the Village.
"Koga? What happened? You look like you've seen a ghost."
Koga took a ragged breath. "It's... It's Naruto."
Hiruzen's face instantly hardened. The relaxed grandfather facade vanished, replaced by the sharp, protective glint of the Hokage. "Naruto? What happened? Did the seal weaken? Did he lose control?"
Koga shook his head, deciding to simply blurt out the impossibility while he still had the nerve.
"Naruto learned the Storage Seal today."
The room went dead silent.
Hiruzen stared at him, his brain trying to parse the sentence. His voice trembled slightly when he finally spoke.
"Koga... I just gave you the order to teach Naruto the Storage Seal yesterday... right?"
"Yeah," Koga replied, his voice heavy.
Hiruzen didn't blink. He simply moved his arm in a sweeping motion, shoving the neat stacks of books, budget reports, and mission scrolls aside. The force was enough that they cascaded off the desk, rolling across the floor in a messy heap.
The Third Hokage didn't care. He leaned forward, his knuckles white against the desk.
"Are you telling me," Hiruzen whispered, "that Naruto learned a functional Storage Seal in a single day?"
"YEAH," Koga replied, the word coming out as a tired exhale.
"DON'T JOKE WITH ME, KOGA!" Hiruzen snapped, his chakra flaring momentarily. "A functional spatial fold? In one afternoon? That is—"
He looked at Koga's face. There was no humor there. Only the shell-shocked look of a teacher who had been eclipsed by his student.
"Oh, my Kami..." Hiruzen breathed.
The Hokage slumped back into his chair, the leather creaking in the silence. He stared up at the ceiling, his eyes tracing the wooden beams as if searching for an explanation.
Slowly, the shock faded, replaced by a profound, terrifying realization. Light returned to his eyes—sharp, calculating, and filled with old memories.
Hiruzen didn't look at Koga. He turned his head slowly towards the wall of portraits—the lineage of Fire.
His gaze lingered on the stern face of the Second Hokage, Tobirama Senju, the inventor of the Flying Thunder God. Then, his eyes drifted to the right, locking onto the bright, smiling face of the Fourth Hokage, Minato Namikaze.
"Koga," Hiruzen said softly, not breaking eye contact with the picture. "Do you understand the meaning of this?"
Koga stood up, his legs stiff. He walked over to stand beside his leader, both of them looking at the legends of the past. "I know. That's why I'm here."
Hiruzen stood up and walked specifically to the portrait of the Fourth. He reached out a hand, almost touching the frame.
"Only those with an innate, monstrous talent for Space-Time Ninjutsu can intuit the geometry of a storage seal that quickly," Hiruzen murmured.
"The faster one draws the storage seal, the better their affinity for Space," Koga finished the sentence, his voice grave. "It's not just about chakra control and Fuinjutsu , Hiruzen. It's about understanding and talent for the Void."
Hiruzen lowered his hand, his expression unreadable.
"Minato took a 2 weeks to make the seal," Hiruzen recalled, his voice thick with emotion. "And that was considered prodigal speed."
"Minato also learned seals with Kushina for a year before attempting it," Koga countered, driving the point home. "He had the best teachers and Kushina . Naruto... Naruto has been studying runes for 3-4 months with me and before that He had nothing but a dictionary and an empty apartment. "
" /....yeahh "
" He did it in just eight hours....Hiruzen "
The two old men stood in silence, the weight of the revelation settling over them. They were looking at something that defied the logic of the ninja world.
The office was deathly silent, save for the rhythmic clicking of Hiruzen's pipe against his teeth. The Third Hokage stood before the portraits of his predecessors, his mind spiraling back into the deep history of the village's most guarded secrets.
In the scrolls written by the Second Hokage, Tobirama Senju, the Storage Seal was never viewed as just a utility. It was the ultimate litmus test. Tobirama had stated clearly: The storage seal is the basic test to determine affinity for the Flying Thunder God.
It was a dual-layered trial. It tested a shinobi's raw sealing talent, yes, but more importantly, it tested their Space Talent.
Without that specific, innate biological gift, the storage seal was an impossible mountain to climb. It didn't matter if you were a Grandmaster of every other art; if you couldn't sense and "catch" the invisible spatial fold to anchor it into a scroll, you would never be a Space-Time user.
Hiruzen looked at his own hands. In all of Konoha, among the five Grandmasters, only two—himself and Koga—actually possessed the spatial sensitivity required to craft Storage seals.
Across the entire village of thousands of shinobi, less than 20 people were capable of making them.
Just being in that group of twenty didn't guarantee greatness, however. Tobirama's notes were brutal:
To be considered a candidate for the Flying Thunder God, one must make the storage seal within a month.
Hiruzen thought of the Fourth Hokage's personal guards. Genma, Raido, and Iwashi were elite Special Jonin, yet they had only "barely" managed to learn the Flying Thunder God Array, a version that required three people to achieve what one man should do alone.
This was why they were stationed at the Konoha Gates; during their watch, they spent their free time crafting the village's precious supply of storage seals Scrolls , and in emergencies, they acted as a human teleportation platform for reinforcements.
These twenty people were the village's logistical backbone. Their main purpose was often shifted from the front lines to the workshop, simply because a storage seal was worth more than a hundred kunai.
"What now, Hiruzen?"
Koga's voice broke the silence, jarring the Hokage out of his memories.
The Third Hokage's gaze drifted back to the empty air, his mind calculating the future he had so meticulously planned for Naruto. It had been a disaster of unintended consequences.
Originally, Hiruzen had wanted to slow Naruto's progress down to a crawl. He wanted the boy to grow up slowly, safely.
But then came the Shadow Clone Jutsu, which allowed Naruto to bypass years of training in months. Then came Naruto's own stubbornness, and the interference of Hattori, who had planted the seed of early graduation in the boy's mind.
Hiruzen had tried to stall again when Naruto asked for Fūinjutsu. He had assigned his friend Koga to teach the boy, specifically instructing him to grind Naruto down with "the basics" for as long as possible.
But four months in, Koga had come to him, practically begging to move on.
"It's irritating watching this," Koga had said. "His basics are way too solid. It's a crime to keep him on runes."
So, Hiruzen had relented, thinking that starting with the Storage Seal would be the ultimate hurdle.
THe Hokage was curious about the boy's talent—being Minato's son—but he also viewed it as a safety valve. If Naruto had no talent, Hiruzen could easily slow him down for his own protection.
Even if he did have talent, it took Minato two to three years to learn the Hiraishin, even that was with Kushina's help and the Second's notes. Hiruzen figured he had years to prepare.
( But eight hours? One afternoon? )
The Hokage turned back toward his desk, the weight of the revelation making his bones ache. He sat heavily in his chair, his hands coming up to massage his tired, bald head.
(Now... not teaching him the Flying Thunder God may actually become a sin,)
Hiruzen thought with a mix of awe and dread. To suppress a talent this bright was to weaken the village itself.
He looked up at Koga, the other bald master in the room, whose head seemed to shine under the office lights like a lightbulb of shared disbelief.
"Keep teaching him the storage seal for one month," Hiruzen commanded, his voice tired but resolute.
"Let him master the variations. Let me think this through until then."
Koga understood. The old sealer offered a dry, short nod. "All right..."
With those words, Koga turned and walked out of the office, his shadow stretching across the floor. He left the Hokage alone with the portraits of the past and the terrifying, lightning-fast future of a boy who was already outrunning everyone's expectations.

Konohagakure no Sato:
Sealing Corps Workshop — Late January
The month had passed in a blur of black ink and white smoke. While the rest of the Academy students were struggling with basic history or target practice, Naruto had turned his corner of the Sealing Corps into a high-speed production line.
Using dozens of Shadow Clones, coordinated by the MindHub and optimized by the Great Sage, Naruto hadn't just mastered the Storage Seal—he had industrialized it.
Naruto quickly realized that space was the most expensive commodity in the shinobi world. By applying his Calligraphy Skill and his system-boosted precision, he produced scrolls that were more stable and efficient than the standard market fare.
Naruto remembered the total fortune he earned this month .
-----------------------
Storage Scroll : C-Rank Seal (Small)
Usage Capacity - Basic Tools
Market Value - 50,000 Ryo
quantity produced - 40
Total revenue - 2,000,000 Ryo
-------------------------
Storage Scroll : C-Rank (Medium)
Usage Capacity - Large Weapons/Supplies
Market Value - 150,000 Ryo
Quantity produced - 10
Total Revenue - 1,500,000 Ryo
----------------------------
Storage Seal : B-Rank
Usage Capacity - Heavy Equipment/Provisions
Market Value - 500,000 Ryo
Quantity Produced - 3
Total Revenue - 1,500,000 Ryo
-----------------------------
Chakra Ink Cost + Fuinjutsu seal cost = 500,000 ryo
Total Fortune = 4,500,000 Ryo
----------------------------
In just thirty days, Naruto had amassed a fortune that most Chunin wouldn't see in five years. This wasn't just pocket money; this was the foundation for his own private research and development.
While mass-producing standard seals, Naruto utilized the System to push his technical limits. The "Standard Storage Seal" was a C-Rank hurdle for those with spatial talent, and Naruto had cleared it with room to spare.
Standard Storage Seal : Level 3 ( 16/100 )
However, the real breakthrough came from a System Reward. Naruto remebered the sytem reward that he got from the Konoha warehouse. This seal was a much complicated and bigger storage seal .
Naruto presented it to Koga after the month.
Ofcourse He didn't tell Koga it was from a system; he presented it as an "experimental variation" he had been working on during his late-night sessions.
At the end of the month, Koga sat in his office, his eyes twitching as he examined the scroll Naruto had placed on his desk.
"You're telling me," Koga said, his voice dry, "that you 'tweaked' the anchor points to overlap the spatial folds?"
"I thought it seemed more efficient, Sensei," Naruto replied with a practiced, innocent shrug.
Koga unrolled the scroll. The runes were dense, interlocking in a way that made the old man's head spin. He channeled a pulse of chakra into it. The seal didn't just open; it expanded with a hum of pure, high-grade spatial energy.
"This... this is a B-Rank Large Capacity Storage Seal," Koga whispered. "The internal volume is nearly double the standard military grade. And the chakra cost to activate it is 15% lower."
Koga looked at Naruto, then at the clock, then back at Naruto. He felt like his entire career as a Seal Master was being condensed into a footnote by a eleven-year-old.
"I'll have this evaluated by the full board," Koga said, carefully rolling the scroll back up. "A breakthrough in capacity like this... it's worth a massive amount of Merits. The village will likely buy the rights to this seal from you. You've done more for the logistics department in a month than most apprentices do in a decade."
This was the day that Naruto was acknowledged and Recognized by the Sealing Corps as a "Logistical Genius."
Naruto was also rewarded an A rank Jutsu merit and 1,000,000 Ryo .
-----------------------------------------------
Konohagakure no Sato:
Sealing Corps Workshop ( 3 days later )
After a month of mass-producing storage scrolls and padding his bank account with 5 million Ryo, Naruto walked into Koga's office with a request that made the old master stop mid-sip of his tea.
"You want what?" Koga asked, squinting.
" 100 grams of Chakra Metal, Sensei," Naruto replied, his voice calm but determined.
Koga choked slightly. "100 grams? Do you know the market rate for that? It's enough to make a high-grade trench knife or weave a mesh for a Jonin's flak jacket. What does an Academy student need with the most conductive material in the world?"
"I want to make a pen," Naruto said.
Koga stared at him. Then he laughed. Then he realized Naruto wasn't joking.
"A pen. You want to waste the village's strategic reserves on... stationary?"
"Not a normal pen," Naruto countered. "A Chakra Ink Fountain Pen. No more dipping brushes. No more carrying ink bottles that can break in combat. A tool that allows a Sealer to draw a storage seal or an explosive tag as fast as they can write a signature."
Koga Sensei was interested at the idea , and Naruto spend a whole afternoon while explaining his idea .
The idea was revolutionary enough that Koga dragged Naruto to the Hokage's office to explain it to Hiruzen. The Third Hokage listened, his pipe smoke swirling around his head.
Hiruzen, the "Professor," saw the tactical implications immediately. The efficiency increase in making seal and also If a shinobi could apply seals mid-combat with a handheld device, the versatility of Konoha's forces would triple.
"It's a bold vision, Naruto," Hiruzen said, pulling a small, lead-lined box from his desk drawer. Inside sat a dull, greyish-blue nugget of metal.
"Most would ask for a sword. You ask for a pen . Consider this a village investment."
Koga grumbled, his bald head practically glowing with irritation.
"I'm going to have to supervise this, aren't I? Fine. But don't expect me to hold your hand when the metal resists your chakra."
Naruto spent the next month in a fever dream of creation. This was where his "hidden" talents truly shone.
Blacksmithing: Using his System-granted skills, he smelted the chakra metal with extreme precision. He didn't just melt it; he "folded" his own chakra into the grain of the metal to ensure perfect conductivity.
Sculpting: Using his past-life memories of Earth-style fountain pens and capillary action, he sculpted a microscopic "feed" system inside the nib.
MindHub & Great Sage: These calculated the exact flow rate needed for high-viscosity chakra ink, ensuring it wouldn't clog or leak during high-speed movement.
By late February, the "Uzumaki Mark I" was finished.
It was a sleek, midnight-blue cylinder with a nib made of polished chakra metal that shimmered like a star.
Naruto presented the prototype to the two "Baldy Senseis" in the Hokage's office. He took a blank scroll, and with a flick of his wrist, he drew a Level 1 Storage Seal in under three seconds. The ink was perfectly uniform.
Hiruzen and Koga leaned in, examining the device like it was a legendary relic.
Evaluation by Koga & Hiruzen
----------------------------------------
Pros:
Speed - "The removal of the 'dipping' phase reduces seal time by 60%. This is life-saving in a skirmish."
Precision -"A brush is organic and soft. This nib is rigid. The line-work is surgical, allowing for perfect rune execution.
Micro-Sizing - "The minimum size for a legible rune has dropped by 50%. You can fit a complex storage seal on the head of a nail."
Versatility - "You can now etch seals directly onto curved or small surfaces like wire, rings, or kunai handles with ease
Consistency - "Chakra metal nibs ensure the ink is 'pre-charged.' There are no weak spots in the runes. It's a perfect seal every time."
Stealth - "No clinking glass bottles. A Sealer can hide this in a sleeve like a hidden blade."
Cons:
Fragility - "If that nib hits stone during a fall, the chakra metal is too brittle. It's a precision instrument, not a weapon."
" If someone puts enough presurrethen it can break too "
Cost - "At current metal prices, each pen costs as much as a B-Rank mission payout. Mass production is impossible."
Control - "A Genin or even Chunin Sealmaste with poor control would 'blow' the ink reservoir with a chakra spike. It requires a steady hand."
Too Much precision -" most seals are required to be used in cojunction with Sealing Brush , Brush can also dish more runes at a time by chakra control , the pen is also not eligible for those "
" need to find new ways to use the seal with the pen "
--------------------------------------------
"It's a masterpiece of a work, Naruto," Hiruzen admitted, handing the pen back. "But it is a specialist's tool. , The ability to etch micro-runes on equipment could change how we arm our ANBU"
"That's the idea," Naruto grinned, tucking the pen into his pocket. "I plan on being a Seal Grandmaster."
Koga sighed, rubbing his bald head. "Just don't lose it. If that nib breaks, I'm not giving you another gram of metal for a decade."
The 90 grams of leftover Chakra Metal sat in a lead-lined pouch on Naruto's belt—a shimmering weight of untapped potential. Even after his trial-and-error phase, Naruto's Blacksmithing skill had allowed him to resmelt every failed nib, losing nearly nothing.
Hiruzen and Koga knew he was hoarding it. Any other student would have been forced to return the surplus, but after seeing the Seal Pen, the two old masters were playing a long game. They didn't just want the metal back;
They wanted to see what the "Boy" would do with that chakra metal .
The Hokage had already tallied the merits. Between the B-Rank Large Capacity Storage Seal and the invention of the Seal Pen, Naruto was sitting on a mountain of village contribution points. But Naruto still hadn't asked for anyhing yet .
Using the Seal Pen's microscopic precision, Naruto spent the next thirty days refining the very concept of "Ninja Tools." He realized that the standard explosive tag was a blunt instrument. He wanted a scalpel.
Naruto made quite a few types of tags but only showed 3 tags for the village's eyes .
Supported by MindHub and the Great Sage, Naruto developed a series of specialized tags that utilized "Dual-Layered" logic—a feat that was nearly impossible with a traditional brush.
New Tags -
Micro-Explosive Tag : Size of a postage stamp. High-density chakra compression. Can be stuck to a target's zipper, collar, or weapon without being noticed.
Soot Smoke Tag : Seals Naruto's Soot Cloud Jutsu chakra inside.Releases superheated ash and blinding particulate. A portable environmental hazard.
Delay Tag : Uses a "Siphon Loop" to delay activation by 5 to 60 seconds.Perfect for traps or "timed" sabotage while the user escapes.
After makeing these Naruto reported to Koga Sensei , and after seeing the tags , koga sensei reported to Hokgae
Later in the evening -
Naruto and koga sensei went to the Hokage's office, but this time the atmosphere was different. There was no tea. The "Baldy Council"—Hiruzen and Koga—were joined by a silent ANBU Commander lurking in the shadows ,
There were also other department heads inside the office .
Even Hattori Sensei was There .
Nara Shikaku Was also there .
Yamanaka Inoichi was also there .
They soon head to The exclusive training ground for the demonstration.
Naruto laid out the three tags. He demonstrated each Tag
Naruto stood over the wooden crate, his movements deliberate and uncharacteristically steady. Gone was the loud-mouthed genin; in his place was a shinobi who had finally tapped into the terrifying precision of the Uzumaki.
"The problem with standard tags is that everyone sees them coming," Naruto said, his voice low as he looked at his teammates. "These? You won't even know the fight is over until it's already done."
He reached for the first slip of paper. or should one say a Micro stamp Card
The Micro-Explosive Tag
Naruto picked up a scrap of paper no larger than a thumbnail. With a flick of his wrist, he "accidentally" brushed past a training dummy, his fingers ghosting over the metal hilt of its kunai.
He stepped back and held up his hands. The tiny stamp was gone, stuck perfectly flush against the underside of the kunai's ring. It was invisible to anyone not looking for it with a magnifying glass.
Naruto snapped his fingers. Even with its tiny size, the high-density compression triggered a sharp, white-hot crack. It didn't just explode; it shattered the steel of the kunai into fragments.
"Stick that on a zipper or a sandal strap," Naruto grinned. "They lose a limb before they even hear the hiss."
The Soot Smoke Tag
Next, he picked up a tag etched with dense, swirling ink patterns that seemed to pulse.
Naruto slapped the tag onto the center of the training ground and channeled a burst of chakra. Instead of a bang, there was a heavy thrum.
A violent geyser of dark smoke erupted. It wasn't just smoke; it was a gritty, blinding particulate that clung to the skin and lungs. Within seconds, the area was a "portable hazard zone"—the air turned gray,
"It's not just for hiding," Naruto explained, his eyes glinting through the haze. "It's for making them breathe chimney while they're blind"
The Delay Tag
Finally, Naruto laid out the most complex seal, one featuring a unique "Siphon Loop"—a circular ink line that seemed to trap the chakra in a spinning orbit.
He activated the tag and dropped it at his feet. He then walked casually to the other side of the clearing, sat down, and began counting on his fingers.
For fifty seconds, the tag did nothing. It sat silent and inert. Then, the Siphon Loop finally collapsed under its own weight.
Boom.
The ground buckled exactly one minute after he'd left the "crime scene."
"The Siphon Loop eats the chakra until it can't hold any more. It's the perfect 'I was never there' card."
Hiruzen's pipe smoked from his mouth. Hattori's eyes shone with a terrifying, professional light.
Koga whispered, leaning over the remains of the dummy. "To coordinate a spatial release and an elemental ignition in a single sequence... Naruto, do you realize what you've done?"
"I made a better bomb," Naruto said simply.
"No," the Hokage interrupted, his voice grave. "You've created a game changer. If the ANBU carry these, a single squad could wipe out an entire platoon before they even realize they're being tracked. The Delay Tag alone would revolutionize our Assault tactics."
Hiruzen looked at Naruto, then at the ANBU Commander, who gave a sharp, appreciative nod from the shadows.
"The Soot Tag and micro Explosion tag " Hiruzen continued, his gaze returning to Naruto, "is a weapon of war and secrecy . It's efficient, cheap to produce with your pen, and utterly versatile. Koga, begin the 'S-Class Secrecy' filing for these designs immediately. No one outside this room—and the production team—can know these exist."
The Hokage Office : [ The Rewards ]
The atmosphere in the room was heavy with the scent of old paper and the realization that the technological balance of the shinobi world had just shifted.
Naruto stood before the "Baldy Council " but the power dynamic had fundamentally changed. By decree of the Third Hokage, Naruto Uzumaki was officially a Special Consultant to the Sealing Corps.
This wasn't just a title; it was a golden key to the village's restricted assets.
The Third Hokage signed the official procurement order. Because these new tactical tags—the Micro-Explosion, the Soot Cloud, and the Delay Tag—required the surgical, microscopic precision of Naruto's Chakra Metal Fountain Pen, they were categorized as "Elite Tier" munitions.
Standard sealers couldn't replicate the density of the runes.
For now , Naruto held a functional monopoly on the village's next generation of tactical munition
The New Military Pricing Contract:
Standard Explosion Tag: 4,000 Ryo (Market Adjusted for High Quality)
Micro-Explosion Tag: 6,000 Ryo
Soot Cloud Tag: 3,200 Ryo
Delay Tag: 5,500 Ryo
For every single tag the village produced under his guidance or using his patented designs, Naruto would receive a 1,000 Ryo royalty.
Given that the Sealing Corps intended to outfit every ANBU operative and Jonin-commander with these, Naruto's initial 5 million Ryo was quickly increasing .
The Contract time was for 10 years , except for this naruto was also given 3 B rank jutsu merit for the three tags .
"You have given the village a tool we didn't know we needed," Hiruzen said, his voice echoing in the quiet office. He reached into a hidden compartment beneath his desk and pulled out a heavy, dark-red card ..
"The creation of the Chakra Metal Fountain Pen is not just an 'improvement.' It is a fundamental shift in how Fūinjutsu is applied . For this invention, and the subsequent mastery you've shown in miniaturization, I am granting you an S-Rank Merit."
Hiruzen pushed the Metal card across the desk, engraved with the terrifying seal of the Forbidden Scroll (Kinsesho).
"You are granted one exchange," Hiruzen stated, his eyes locking onto Naruto's. "You may select one S-Rank Jutsu from the Forbidden Scroll of Seals. This is a reward usually reserved for the village's greatest heroes and S-rank shinobi. Think carefully, Naruto. Once selected, there is no going back."
Koga handed Naruto a matte-black identification card with a silver leaf insignia. "And this is your Black Permit. It bypasses the civilian markets entirely. If you need rare ores, forbidden ink ingredients, or high-density scrolls, you order it through the Sealing Corps supply line. No questions asked. "
Koga leaned in, his bald head reflecting the dim light of the office.
"You've got 80 grams of chakra metal left, kid. You saved it by being efficient with your smelting . Now That metal belongs to you now. Combined with this permit and your royalties, you have the resources to build your own private arsenal."
--------------------------------------
Author's notes :
I need some ideas for new sign-in reward .
I am also confused about another thing
Should Naruto choose Flying Thunder God or Some other S Rank jutsu
