Yagami Sora returned to his dormitory.
But instead of immediately sleeping—
He sat cross-legged on the bed and slowly closed his eyes.
His consciousness sank inward.
Into the deepest layer of his mind.
There—
Suspended in a void of blue light—
A massive interface hovered silently.
[Strongest Dimensional System]
Host: Yagami Sora
Primary Ability: Vector Manipulation (Level 5 — Intermediate)
Current Points: 15,000
(Obtained from the Kyoto Exchange Event and the Yasohachi Bridge mission)
Unlocked Skills:
Vector ReflectionGravity ManipulationBioelectric ManipulationAir Vector Control (Wind)Plasma Generation (Beginner)
"System."
"Open the advancement panel."
The interface shifted instantly.
A gigantic skill tree unfolded before him.
At the very top—
Two icons remained locked.
Both were grey.
Yet they radiated a terrifying presence.
[Black Wings][White Wings]
These were the ultimate evolutionary states of vector manipulation.
Symbols of a power that transcended ordinary human limits.
Black Wings
Activation Condition:
Extreme anger or despair.
Effect:
Massive amplification of calculation ability.
Allows manipulation and analysis of unknown forms of energy, including exotic phenomena beyond conventional physics.
A destructive force capable of overwhelming even supernatural systems.
White Wings
Activation Condition:
Absolute protective intent or divine awareness.
Effect:
Extreme stabilization of vector calculations.
Grants resistance to higher-dimensional mental interference and limited manipulation of causality vectors.
Sora stared at the progress indicators beneath them.
Black Wing Unlock Progress: 85%
White Wing Unlock Progress: 30%
"Almost there…"
He murmured quietly.
"Simply crushing weaker opponents isn't enough."
"To surpass Level 5 and reach Level 6 — Absolute Ability User, I need stronger stimulation."
Vector manipulation was not merely power.
It was calculation.
Understanding.
Deconstructing the laws governing reality itself.
Black Wings represented destructive calculation.
White Wings represented protective calculation.
Chaos and order.
Both were extremes of the same system.
Yet even after defeating multiple Special Grade-level threats, Sora still felt an invisible barrier.
"Then I need more computing capacity."
His gaze shifted toward the system shop.
One module glowed softly with pale gold light.
[Advanced Computing Assistance Module]
"System."
"Purchase it."
A prompt appeared instantly.
[Cost: 10,000 Points]
Confirm purchase?
"Confirm."
The moment the points disappeared—
A tidal wave of information flooded his brain.
It felt like replacing an outdated processor with a quantum computer.
No—
More than that.
It felt like rising from a two-dimensional plane into three dimensions.
The world suddenly unfolded before him.
Every molecule in the air.
Every dust particle.
Every vibration in the floor.
All of it became data.
Clear.
Precise.
Calculable.
He could even see the flow of cursed energy drifting through the air.
Previously invisible currents now appeared like luminous rivers.
Their direction.
Their speed.
Their density.
Everything.
"...So this is evolution."
Sora slowly opened his eyes.
Blue light flickered faintly in his pupils.
Not cursed energy—
But the projection of pure computational processes.
His mind now processed information at terrifying speed.
To him—
The world seemed slower.
Almost as if time itself had stretched.
He clenched his fist lightly.
The air around his hand twisted.
A transparent vortex appeared.
This wasn't brute force.
It was precise manipulation of spatial vectors.
He had calculated the weakest structural point in the surrounding air—
Then folded it.
"At this level…"
"I should be able to analyze more complex techniques."
For example—
Gojo Satoru's Limitless.
Infinity was essentially the infinite division of space.
A phenomenon similar to the Achilles and the tortoise paradox.
Previously Sora could only counter it indirectly with reflection.
But now—
Perhaps he could analyze the algorithm of spatial division itself.
And break through it.
Or—
Ryomen Sukuna's slashing techniques.
Those attacks sever space directly.
But if Sora could calculate the spatial coordinates of the slash before it formed—
He might be able to cut the cut itself.
An amusing thought.
Suddenly—
Another system notification appeared.
[Host Strength Has Reached Bottleneck.]
[Special Reward Quest Triggered.]
Quest: Echoes of Time
Description:
Some regrets cannot be erased—even by the strongest power.
Unless…
We return to the past.
Objective:
Travel to the Hidden Inventory timeline and alter the outcome of that summer.
Reward:
Full Unlock — Vector Manipulation: Black WingsRevelation of a hidden truth about the world
Activation Condition:
Automatically begins after completion of the current story arc.
Sora smiled faintly.
"Returning to the past…"
The summer in question.
The turning point of the modern jujutsu world.
The mission to protect Riko Amanai, the Star Plasma Vessel.
The rise of the legendary duo—
Satoru Gojo
and
Suguru Geto.
And the man who shattered that era.
The Sorcerer Killer.
Toji Fushiguro.
A man with Heavenly Restriction—
A body with zero cursed energy.
Yet powerful enough to kill the strongest sorcerers.
That summer changed everything.
Riko's death.
Geto's descent.
Gojo's isolation at the summit of strength.
The entire trajectory of the jujutsu world shifted.
"If that moment could be rewritten…"
Sora whispered.
"…then the future might change as well."
His eyes darkened slightly.
"Toji Fushiguro…"
"The Sorcerer Killer."
"You can nullify cursed techniques with the Inverted Spear of Heaven."
"You can disrupt cursed energy."
"But can you erase physical laws?"
"Can you sever momentum?"
"Can you cut vector calculations?"
Sora closed the system interface.
Then lay down on the bed.
He fell asleep almost instantly.
Because he knew—
A far greater stage was approaching.
A battle that would transcend time itself.
Where science would confront sorcery.
And the fate of the jujutsu world—
Could be rewritten.
