The moment he sat down, something shifted.
Not a voice. Not words.
A pressure.
It began behind his ribs, low and tight, as if his chakra coils had suddenly remembered something they had been waiting for. The faint trickle he had learned to draw out over the past month under Uchiha Daichi's instruction surged without warning.
It wasn't violent.
It was decisive.
Chakra flowed through him in a smooth, uninterrupted current, no longer stuttering in fragments. The sensation rose up his spine and gathered behind his eyes.
Itsuki froze.
Heat pooled in his vision.
Then—
Clarity.
The classroom sharpened into layers. He could see the minute tremor in Sarutobi Asuma's clenched jaw. The uneven rhythm of Nohara Rin's breathing. The subtle shift of Takeda Hiroto's weight as he turned toward the blackboard.
The world had edges now.
Scarlet bled into his vision.
A single tomoe spun slowly in each eye.
Takeda Hiroto stopped mid-sentence.
"…Sharingan?"
The word left him quietly, but the tension in the room tightened like a drawn wire.
Several students stiffened. Even at five, the name meant something. The Uchiha clan's dōjutsu was not a bedtime story. It was a symbol. A weapon.
Itsuki understood what that silence meant.
Awakening the Sharingan at five was abnormal.
Most Uchiha struggled for years. Some never awakened it at all. Even those who did typically faced extreme emotional shock before their eyes changed.
And he had done it standing in a classroom.
He exhaled slowly.
The chakra behind his eyes did not recede. It deepened.
Something in his chest tightened again. Not pain.
Recognition.
The pressure surged a second time.
The tomoe spun faster.
A pulse of chakra rippled outward from his coils, steady and controlled, but undeniably stronger than moments before. The scarlet darkened. A second tomoe formed beside the first, crisp and unmistakable.
Two.
A faint scrape of a sandal against the floor broke the silence.
"Two tomoe…" Takeda Hiroto muttered under his breath.
He had been a chūnin for years. He understood what he was looking at.
This was not a gradual evolution over months of strain.
It had happened in seconds.
Across the room, Uchiha Obito stared openly. Sarutobi Asuma's earlier irritation vanished, replaced with something more complicated.
Itsuki blinked once.
The motion felt natural.
The classroom slowed around him, every gesture readable, every flicker of emotion laid bare.
So this is the Sharingan, he thought.
Not power.
Perception.
The world revealing its intentions before they fully formed.
He could feel the strain, though. The chakra consumption was heavier than his coils were accustomed to. Even with the earlier surge, sustaining it would be inefficient.
He let the analysis settle.
This was not the time.
Takeda Hiroto cleared his throat, regaining control of himself.
"Uchiha Itsuki. That is enough. Dismiss your Sharingan and take your seat."
Itsuki held the teacher's gaze for a brief moment, then allowed the chakra in his eyes to unwind.
The scarlet faded.
The tomoe vanished.
The classroom exhaled.
He sat.
His heartbeat remained steady.
Inside, however, the change was undeniable. His chakra network flowed more smoothly than before, fuller, closer to the threshold expected of a newly graduated genin rather than a first-year Academy student.
Not overwhelming.
Not limitless.
But real.
He rested his chin lightly on his hand again and stared out the window as if nothing extraordinary had occurred.
The Hokage Monument stood in the distance, stone faces unmoved.
Awakening early changes nothing, he told himself.
Talent invites attention.
Attention invites scrutiny.
And scrutiny, within the Uchiha clan… could become dangerous.
If anything, this only confirmed what he had already resolved.
Strength would not be optional.
It would be survival.
