Konoha Year 53
Land of Fire – Konohagakure
A six-year-old boy sat cross-legged in his room, intently reading a scroll titled "Chakra Extraction." His name was Kazuki, and unlike most children his age, his mind was consumed by one thought: power.
As a transmigrator, Kazuki understood the brutal reality of the Naruto world. Without strength, he would be nothing more than cannon fodder. Even at his young age, he refused to waste time. Every free moment was dedicated to training—he had to grow stronger, and fast.
The first step? Extracting chakra.
Time passed as Kazuki focused on comprehending the technique. Just as he was deep in thought—
Creak.
The door to his room suddenly swung open. A small girl with her hair tied into two buns peeked inside, half her face visible.
"Brother, dinner's ready! Come eat!" she called in a cheerful, childish voice.
Kazuki looked up and smiled. "Got it, Tenten."
Standing before him was none other than Tenten, the future weapon master and teammate of Neji Hyūga and Rock Lee. Though she had a bright personality, in the original timeline, she was never one of the strongest shinobi.
But in this life? She was his little sister.
Yes, Kazuki had been reincarnated into the Naruto world—but unlike many protagonists, he wasn't an orphan. He was born into a normal civilian family with loving parents and a cute younger sister, Tenten. Their family ran a weapons shop in Konoha, specializing in ninja tools.
Since their parents often traveled outside the village to trade, Kazuki and Tenten had been home alone for the past few days. That meant cooking had fallen to Tenten, who surprisingly enjoyed it.
"Brother, hurry and try it! Is it good?" Tenten asked eagerly, her eyes shining with anticipation.
Kazuki, who had been surviving on instant ramen for days, looked at the steaming bowls of fresh miso ramen on the table. His eyes lit up.
"Ramen? Tenten, you're amazing!"
The rich aroma filled the air, making his stomach growl.
"Itadakimasu!"
The sound of chopsticks clinking and noodles being slurped echoed through the house as the siblings enjoyed their meal together.
After dinner, Kazuki returned to his room, unrolled the Chakra Extraction scroll, and continued his training.
Normally, if one practices ninjutsu while simultaneously refining chakra, the efficiency of chakra refinement improves significantly, yielding greater results with less effort.
Unfortunately, Kazuki's parents are civilians. Their family possesses no ninjutsu scrolls or secret techniques. In the ninja world, such scrolls are among the most valuable assets of a family or even an entire village. Aside from attending a ninja academy, many individuals from ordinary backgrounds struggle to learn ninjutsu, with some unable to extract chakra at all.
Before the Second Hokage, Tobirama Senju, established the Ninja Academy, nearly all shinobi in the village hailed from established clans. Commoners had little to no opportunity to become ninjas. Fortunately, this situation has improved considerably over time.
Kazuki's family, however, runs a business specializing in ninja tools. Though his father is not a ninja, his frequent dealings with shinobi have allowed him to leverage connections and acquire chakra refinement scrolls at a price.
After thoroughly reading the contents of the scroll, Kazuki closed his eyes and prepared to extract chakra. In the world of Naruto, chakra is the fundamental energy source used by ninjas. Refining chakra involves drawing physical energy from the body's 130 trillion cells and combining it with spiritual energy.
Following the method outlined in the scroll, Kazuki began extracting these two energies, carefully merging them together.
Finally— The first trace of chakra manifested within him! The entire process took less than three minutes.
Feeling a surge of excitement, Kazuki was about to celebrate when an unexpected electronic voice echoed in his mind:
[Ding! Chakra detected. Congratulations, Host, for successfully activating the "God-Level Forging System!"]
[System panel opening...]
A translucent virtual panel appeared before him:
[Host: Kazuki]
[Age: 6 years old]
[Forging Level: Beginner]
[Unlocked Weapons: None]
[Self-Created Weapons: None]
"God-Level Forging System?" Kazuki was momentarily stunned before quickly regaining his composure.
"A system that helps forge weapons? No... Since it activates upon sensing chakra, perhaps the items it forges aren't just ordinary weapons. Could it include legendary artifacts like the Bashōsen (Banana Palm Fan) or the Six Paths' Treasured Tools?"
Kazuki's eyes gleamed with excitement as he speculated about the system's potential. Just then, the system's voice sounded again:
[Ding! Mission Released: Crude Iron (100g)]
[System Reward: Primary Forging Blueprint – Clone Kunai]
"That's all? Just 100 grams of crude iron to complete the mission?"
After a brief moment of hesitation, Kazuki quickly deduced that the mission was simple because the system had only just been activated.
Crude iron is one of the most basic materials used in weapon forging. Before crafting weapons like kunai or shuriken, the primary material required is crude iron.
Luckily, Kazuki's family owns a weapons shop, and their backyard has plenty of excess crude iron lying around. He grabbed a fist-sized chunk, more than enough to complete the task.
[Ding! Mission Complete! System Reward: Primary Forging Blueprint – Clone Kunai has been issued!]
A flood of information entered Kazuki's mind, instantly granting him knowledge of the forging process for the Clone Kunai.
[Clone Kunai]
[Forging Difficulty: *]
[Skill: Instantly releases the Clone Jutsu upon impact, creating a tangible decoy]
"What an incredible forging technique!"
Fascinated by this newfound ability, Kazuki couldn't help but feel eager to put it to the test.
"Perfect! There's a small forge in the backyard—I can try crafting it right away!"
