Year One of Konohagakure.
On the edge of the Hokage Rock, a young man stood silently, his gaze sweeping over the gradually forming village below. His name was Kai, and his expression right now was filled with awe and disbelief.
He can't quite believe it at first, but now. There was no doubt about it.
He had transmigrated—but not into a regular Naruto timeline. No, Kai now existed within a space-time matrix composed of seven parallel Naruto worlds, each with its own branching histories and altered events.
Then came the system's mechanical voice, echoing crisply in his mind:
[Main Quest: Choose one major force in each timeline. Guide it to unify the ninja world. After unification, maintain stability for 20 years. Complete all seven, and...]
[Reward: Instant Immortality. Eternal Life.]
A tempting reward—but the mission was impossible, even a kage would cry at this.
Because this was the Naruto universe, after all, a world where mountains shattered from battles and tailed beasts could wipe out nations. The concept of world peace here was laughable—even the Sage of Six Paths barely held it together.
And yet, the system had chosen Kai, a formerly ordinary high school student with a decent GPA and an unhealthy addiction to anime, as the one to unite seven war-torn timelines.
Logically speaking, it was impossible.
Each world had to be unified under a single force. That unity had to hold for two decades. And this had to be repeated across seven separate realities.
Even with Kai's knowledge of the entire Naruto storyline—canon, filler, and databooks included—the challenge was near-impossible.
Fortunately, the system had not sent him empty-handed.
System Notice:
Daily Time Travel: The host could freely jump between timelines, 10 times per day. Duration of stay: Unlimited.
Faction Binding: The host could bind to a force in each world to receive a Newbie Gift Pack.
Milestone Rewards: For every successful unification, the system would unlock new features and powers.
Kai considered the situation carefully.
Despite the insane conditions, the final reward—eternal life—was far too alluring. If there was even the slightest chance of success, it was worth trying.
He opened the system panel and chose to bind himself to Konohagakure.
The decision wasn't out of loyalty, it was a strategy.
Kai had never been particularly fond of Konoha, or at least not all of its people. But from a tactical perspective, Konoha had always been the strongest village in nearly every era.
With reincarnations of Asura and Indra, legendary shinobi, and near-endless plot armor, Konoha was, frankly, Easy Mode.
There was no point in playing on Hell Difficulty when one had the option to cheat.
[Ding! The Novice Gift Pack has been opened.]
[Congratulations. Host, you have obtained a pair of (Rinnegan)! (Automatically replaced)]
[Congratulations. Host, you have obtained a Ninja Tool: (Universal Pouch)!]
[Congratulations. Host, you have obtained (3) Modern Physical Exchange Coupons!]
The moment the Rinnegan was obtained, it silently replaced his normal brown eyes. Kai hurriedly pulled out a smartphone from the recently obtained Universal Pouch and checked his reflection in the dark screen.
There, his eyes—now rippling with violet circles—gleamed like the eyes of a certain god.
In an instant, his dynamic vision skyrocketed. He could see the tiniest insects fluttering in the distance and count the compound eyes of a fly mid-flight.
It took time for him to adjust to the overwhelming clarity, but eventually, he managed to calm the sensory overload.
Unfortunately, the Rinnegan's powers remained sealed. He had no chakra, no control, and no energy flow.
But still, appearance alone carried weight in the shinobi world.
In a society obsessed with bloodlines and power, this somewhat strange pair of eyes could intimidate or convince even the proudest of people.. And that alone meant Kai could finally start moving the pieces on the board.
His eyes turned toward the rising structure of the Hokage Building.
If there was ever a time to unify the world, it was now, before the other villages gained footing, when Konoha stood uncontested as the superpower.
With Hashirama and Madara still in their prime, Konoha alone could crush the world if it truly wanted.
But therein lay the real challenge.
The stronger a person is, their heart and will are more determined. It is difficult to convince them otherwise than to change their beliefs and paths!
Not everyone is as easily persuaded by words as Nagato.
If you are not careful enough, if the negotiations fail, you might end up fighting a Susanoo alone.
So, Hashirama was the safer bet.
[Timeline: Founding Era]
[Year: 1st Year of Konohagakure]
[Unification Progress: 30%]
Outside the Hokage Building...
"Brother, where are you going!?"
The door had barely creaked open before Tobirama Senju's sharp voice cut through the hallway.
"Uh…"
"Don't tell me you're going to gamble again! You have official duties, brother!"
"No, no…"
"Then it must be Madara, right?"
"Tobirama, How'd you know? ahahaha." Hashirama chuckled and scratched the back of his head.
"Hmph. You only smile like that when you're off to see him." Tobirama folded his hands and snorted in dissatisfaction.
Hashirama didn't deny it. "He asked me to meet him at Nanga Shrine. Probably something important."
Tobirama's expression darkened. "Nanga Shrine? Big brother you better be careful, Madara has been acting more and more suspicious recently. I wonder what he is planning. You better pay attention! Don't be fooled by him again!"
Tobirama knew that he couldn't stop his elder brother from going after his old lover, so he could only keep nagging.
Fortunately, Big Brother has already taken office as the first Hokage, so Madara shouldn't be able to cause much trouble.
"Good! good!"
"I'm leaving first. By the way, tell Mito that I won't be coming back tonight..."
Tobirama's face darkened, and he stared at him speechlessly.
Just then, a ripple appeared in the air not far from them.
From nothing, a figure appeared in the corridor.
Tobirama stared at the figure warily 'It's not a Flying Thunder God technique, it's more secretive and abrupt than the Flying Thunder God technique! There's no sign, and no chakra fluctuation.
Even Hashirama was stunned.
What appeared before them is a man who had short black hair, wore a white T-shirt and jeans—a bizarre outfit for any era of the ninja world.
But it was his eyes that captured everything.
The Rinnegan.
Those divine ripples of power, said to be the most powerful dojutsu out of the three dojutsus.
Hashirama tensed up instantly, but still asked in a friendly and carefree manner.
"You are…?"
The young man nodded slightly.
"Senju Hashirama. The First Hokage. Do you have a moment to talk?"
Hashirama studied him. His instincts told him the stranger was dangerous, but he wasn't hostile.
He was composed. Cautious. Deliberate.
Not unlike Hashirama himself.
Behind him, Tobirama appeared in a blur, katana already drawn.
"Who are you?!"
"Tobirama, stop," Hashirama ordered, his tone sharper now.
"But—"
"I said clear the room. I want to speak to this guest alone."
Tobirama gritted his teeth but obeyed. When his brother got serious, even he knew not to push further.
The hallway cleared.
Kai stepped forward, calm and unwavering, his violet eyes meeting Hashirama's.
This was it.
The first move.
And the god of the shinobi of the ninja world was listening.
