Uchiha Ren transmigrated into the world of Naruto at the exact moment Senju Tobirama died.
While the village mourned, he stepped forward.
He crushed Sarutobi Hiruzen’s rise, seized the Hokage seat, and declared himself Konoha’s new ruler—a so-called “benevolent capitalist” with ambitions that stretched across the entire ninja world.
“If I were Hokage, I’d build farms before battlefields.”
 “Infrastructure before war.”
 “Development before sacrifice.”
 “And profit… above all.”
Using the Impure World Reincarnation, he turned Tobirama Senju into an endlessly tireless chakra reactor. With the Multiple Shadow Clone Technique, he became an entire research empire by himself.
He manipulated markets to bleed the Fire Country nobles dry.
 He built the Konoha United Fruit Company, binding the Land of Grass into generations of forced production.
 He reshaped the Land of Rice Fields into his personal economic machine.
 And through “Project Blue Sky,” he harvested billions of ryo from the Land of Lightning.
To the world, he was a savior.
 A reformer.
 The “benevolent father” of Konoha.
But every favor came with a price.
And every debt… grew with interest.
As his reputation spread across the ninja world, Uchiha Ren simply smiled.
(“Uchiha Ren… one day, I’ll hang you from a lamppost!”)
 Tobirama Senju roared from within the laboratory.

Kakuzu stood in front of a three-story building, recently renamed "Ninja World Finance."


Behind the sign was a leaf-shaped logo, but he didn't care.


Inside, a massive screen showed iron price trends over two years.


The latest curve plunged sharply—right after Konoha and Kumogakure signed peace.


Spot trades were handled quickly at counters—pay, confirm, deliver.


Prices were unified, transparent, and centrally controlled.


This was exactly what Uchiha Ren wanted.


But Kakuzu wasn't interested in spot trading.


If it could make money, he might consider it.


A merchant exchanged boxes of cash for paper cards.


He stepped forward and demanded an explanation.


"So it's just betting on future prices?"


"What if prices drop? Then everything's gone."


"If this thing makes money, I'll jump off the building."


Especially now, iron prices were still falling.


Then a white-haired young man walked in.


Elegant clothes, noble aura, guarded by Konoha shinobi carrying cash boxes.


"Buy when no one cares, sell when everyone is watching."


Since futures launched, most traders were losing badly.


Iron prices had dropped further recently.


Even top traders showed negative returns.


Meanwhile, Ren was quietly accumulating.


Even the Daimyō rushed in once with massive funds.


Too much buying could expose everything.


Back in the hall, the white-haired youth noticed the stares.


"You people have no investment vision!"
