After spending a couple of hours training in Konoha, and a couple of days hanging out with friends, one day, he would head out toward his secret base.
He had stuff to take care of. He had his shadow clone act like himself, on a day on which he knew Mikoto wouldn't be near him since she had Uchiha clan stuff to do.
Restrictions. With her around, he had to be quite subtle about his movements since she could tell which one was him and which ones were not.
Odd feeling, but oh well.
After 3 hours of traveling, using his newfound Shunpo, he would arrive there—at the edge of Konoha, near the Whirlpool Village, the base where the clone stored his shit.
He carefully made his way inside, making sure no one was following him. His senses were finely tuned, so he could tell—and for several kilometers around, there was no human near him. So he was goochi. He would be fine for the most part.
Now, he looked at the two seals present in front of him:
[Fuinjutsu: Kuro Hitsugi no In]
Immediately, memories flooded his mind. Not the clone's—his own instincts reacting to what was encoded in it. His chakra responded to it. Recognized it.
He stood back up and exhaled.
"Time to dissect it."
And with that—
POOF—POOF—POOF—POOF!
POOFPOOFPOOFPOOFPOOF—
In a swirl of rapid flashes, the room filled with versions of him—each blinking into existence with precise awareness.
500 clones. Instantly summoned.
Each with instructions:
"You, Section A: Chakra Pressure Mathematics and Sequence Optimization."
"Section B: Seal Encoding and Syntax Translation."
"Section C: Run the Kuro Hitsugi sequence through five iterations with different elemental chakra."
"Section D: Analyze the terrain glyphs for the Five Dragon Seal—make it mobile."
Clones nodded, already forming working groups like engineers with a divine blueprint.
Each one unrolled scrolls, etched new copies with variant formulas, added annotations, tested dummy activations with chakra threads...
It was like a university lab—except every professor was the same 11-year-old boy with god-tier chakra control and no respect for divine limits.
Meanwhile... the original?
He walked toward the edge of the chamber and cracked his neck.
"Magnet Release... next."
With a hand seal—POOF!—40 more clones appeared beside him.
"You know your jobs."
The clones spread out to another chamber, where huge boulders, metallic shrapnel, and chakra-tuned magnetized bars were already laid out like a sandbox for destruction.
Each clone got to work:
One calibrated iron sand patterns in chakra fields.
One tried using positive and negative repelling charges mid-Taijutsu.
A third embedded magnetic nodes in thrown kunai, triggering reversal via chakra threads.
Another? Tried to simulate a railgun.
All in all, he wanted a different version of Magnet Release, one that allowed him to do whatever he wanted.
A version that would allow him to control even the metal in someone's blood.
Making him one of, if not the most dangerous ninja alive.
His pseudo-identity would be the one mainly using those OP jutsu. Wonder how much of a bounty he could rack up—becoming one of the worst criminals alive and all.
Hm. He had a spy network. A small one, but he did have something.
His hidden identity was making sure of that, so he had eyes in every major nation. As of this moment, he was ready to become the puppeteer to those people.
Guide them to the light, one might say.
All of this would have to wait until he was stronger though—after he hit puberty and all.
Meanwhile—
Seijuro unsheathed his blade and stepped into the Kenjutsu Hall.
His hand flicked the sword once.
Lightning danced across its edge.
A whisper of wind followed the motion.
He took a breath. Closed his eyes.
Focused.
Then moved.
Step. Turn. Twist. Slash. Step again.
He began flowing through dozens of styles—his own Mirrorblade variants included—but this time, weaving elemental chakra directly into the strokes.
A vertical slash was Wind.
A parry? Lightning.
A backhand strike? Fire—controlled just enough to scorch, not detonate.
He pushed harder.
"Flow. Don't just coat the blade—make the blade part of the element."
The blade glowed faintly. The chakra began responding better.
Back in the main chamber, one clone shouted:
"Oi! I just made the gravity compression seal explode—again!"
"Run it again with a tighter perimeter and Earth-nature flow!" another barked.
Further back, another raised a hand:
"Shit! The dragons from Goryūtenmetsu started fighting each other!"
"Recode the targeting glyph to ignore chakra signatures marked with the 'ally' tag! That's like... Rule 3!"
"FUCK OFF!"
Hm. Seemed like his clones had more personality than he thought. Oh well. No biggie. It wasn't anything he couldn't handle.
During that small time, he released quite a powerful genjutsu on himself, which will only deactivate in the very unlucky scenario where he is split in half.
Time skip.
He spent quite a while on this. He had to return to Konoha while his clones trained their bodies to the limit. He wished them good luck. Later in the village, he would study in the Jōnin area and so on.
Speaking of Jōnins, he was promoted to a Jōnin like the second he got back. Apparently, his accomplishments were enough for that. The day he turned 12 was the day he had become a Jōnin of Konoha.
That truly was speedrunning the ranking.
Going from Genin to Jōnin in like 2 years... this would be a record that would remain for a long time. Probably unbroken by anyone.
Oh well.
He was offered a spot in the ANBU, which he dutifully accepted. There was a slight special exception made for him. The age requirement for being ANBU was lowered so that this 12-year-old could join.
All that was left was to gather prestige, become an ANBU captain, and get semi-autonomy for dictating what missions to take.
While sure, becoming a member of the ANBU may seem like a bad side, there were some ups to it. He was now more privy to more info.
He would return back to being a normal Jōnin soon—for now, however, he shall serve the ANBU.
A/N 100 chapters. Time to review his stats.
