A Fragment Awakened
That night, Raiden couldn't sleep.
He sat cross-legged in his dorm room, eyes locked on the glowing blue screen before him.
> New Ability Tree: Bloodline Fusion (LOCKED)
Warning: Accessing this tree may awaken suppressed genetics.
System Suggestion: Proceed only if user is mentally stable.
He scoffed. "I'm always stable."
> Initiating Origin Link Protocol…
Playing Memory Fragment 001…
Suddenly, Raiden wasn't in his room anymore.
He stood inside a cold, glass-walled lab. Monitors beeped softly. Scientists in white coats stared at a child—himself—floated in a cylinder of liquid.
> "Subject Zero shows exceptional genetic adaptation. Fusion of multiple Kekkei Genkai succeeded."
"But there are side effects: emotional dampening, memory suppression…"
"We'll send him to that world soon. The shinobi one. Let's see how he performs."
"Begin transfer."
The memory ended.
Raiden opened his eyes, breath shallow.
He wasn't born in this world.
He was created for it.

Raiden narrowed his eyes.

He had none of those… right?
Unless…

Meanwhile: Whispered Rumors and Watching Eyes
Unbeknownst to Raiden, whispers had begun to spread among the upper ranks of Konoha.
In a dimly lit room, Danzo Shimura tapped his cane against the floor.
"This boy… Raiden," he said slowly, "has power even the Uchiha might envy."
One of his ROOT agents nodded. "He fought off a jōnin-class enemy without injuries."
Danzo's eyes narrowed. "Investigate his origin. Quietly. If he's not truly one of ours... we'll make him ours."

Investigation: The Forbidden Records
At school, Raiden sat in the back row as Iruka droned on about chakra control.
But his mind was elsewhere.
He knew he'd get no answers inside the academy.
That night, he made his move.
Slipping past the patrols with silent steps, cloaked in a genjutsu scroll he stole from the library, he entered the Forbidden Archives—where only Jōnin and above were permitted.
He found what he was looking for: a black file labeled "PROJECT ZERO."
It was sealed with chakra.
> System Skill: "Code Decryption" Activated.
The seal faded.
Inside: photos, genetic charts, strange words scrawled across the top.
"Synthetic Shinobi: Universe Transfer Test Subject."
His hands shook—not with fear, but with the weight of knowing.

A Sudden Ambush
But before he could read more, a kunai embedded itself in the wall beside his head.
Raiden turned.
From the shadows stepped a masked ROOT agent.
"You've seen too much."
Raiden sighed. "I'm starting to hate that sentence."
The ninja attacked.
Fast.
Silent.
Deadly.
But Raiden's new Aura Sense activated—he felt the incoming strike before it happened.
The fight was a blur of fists and kicks in the darkened hall, scrolls flying and shelves collapsing. Raiden was faster, smarter—but the agent was relentless.
In desperation, the agent activated a chakra seal—explosive.
Raiden raised a hand.
"Akairo."
In a flash of crimson fire, the fox appeared and formed a shield of flame.
The blast rocked the room.
The agent was gone—dead, or fled.
Raiden's file was burned… but one corner remained.
Three names.
His name… and two others:
"Subject Zero: Raiden Kageyama."
"Subject One: Ayaka."
"Subject Two: Jin."
---
The Others…
He wasn't alone.
He wasn't the only one.
Raiden stood in the ashes of the forbidden room, cloak flickering, eyes glowing faintly.
Somewhere out there… two others like him existed.
And if he was a threat…
They might be worse.
Or more broken.
Or more powerful.
The system chimed.
