The Special Grade cursed spirit tilted its head slightly.
Both of its faces showed confusion.
It could not understand why the human standing before it had not been crushed like the others.
In its perception, the cursed-energy shockwave it had just released should have been enough to erase everything in the hall.
"Hehehe…"
The curse laughed again.
But this time its tone carried a trace of cruelty.
Its body suddenly vanished.
Fast.
Too fast.
Even Megumi Fushiguro, lying on the ground, barely managed to open his eyes.
But his vision could only capture a faint blur.
The curse had already moved.
The next moment—
It appeared behind Yagami Sora.
A pale arm swung downward like a blade.
Its sharpened nails glowed with a cold metallic sheen, easily capable of slicing through armored steel.
If the strike landed—
It would rip out Sora's heart instantly.
"Yagami! Behind you!" Yuji Itadori shouted.
He struggled to stand, ignoring the pain throughout his body.
But he couldn't move fast enough.
Yet Sora didn't even turn around.
CLANG—!
A metallic collision rang out through the hall.
The cursed spirit's arm stopped a few centimeters from Sora's back.
An invisible layer blocked the attack.
The vector reflection field.
Then—
The reaction force erupted.
The cursed spirit's arm was violently thrown backward.
Its body staggered.
Several of its claws cracked under the reflected impact.
"What?"
Yagami Sora slowly turned around.
His hands were still in his pockets.
His expression was cold.
"Didn't you eat today?"
"That little bit of strength…"
"…isn't even enough for a massage."
The cursed spirit roared in fury.
Its pride as a Special Grade entity had been humiliated.
Its mouth opened wide—
And dozens of compressed cursed-energy projectiles fired out like machine-gun rounds.
RAT-TAT-TAT-TAT-TAT!
Explosions echoed throughout the hall.
Each projectile blasted massive craters into the floor.
Concrete shattered.
Dust clouds filled the air.
Sora's figure disappeared inside the storm of explosions.
"Yagami!" Nobara shouted.
Tears formed in the corners of her eyes.
That level of bombardment could destroy armored vehicles.
How could a human survive it?
Then—
A lazy voice came from within the smoke.
"That's it?"
"…How disappointing."
A gust of wind swept through the hall.
Sora waved his hand.
The dust cleared instantly.
He stood exactly where he had been before.
Unharmed.
Every cursed-energy projectile had changed direction the moment it touched the invisible field surrounding his body.
Some were deflected into the ceiling, blasting open the dome.
Others smashed into the floor.
Some even collided with each other mid-air, neutralizing their energy in bursts of light.
Not a single attack touched him.
Not even a speck of dust reached his coat.
This was the terrifying nature of Reflection.
As long as the attack possessed a vector—
Velocity, direction, or momentum—
It could be calculated.
And reversed.
Whether it was a physical strike or cursed-energy blast—
Before Sora's calculations, it meant nothing.
Against a cursed spirit that relied purely on brute cursed energy, his system barely needed effort.
The system was currently operating at less than ten percent computational load.
"Finished?"
Sora finally pulled one hand out of his pocket.
He raised a finger and beckoned toward the curse.
"Then it's my turn."
The cursed spirit paused.
Its instincts screamed danger.
This human was different.
It stopped its reckless barrage and began gathering its cursed energy.
The Sukuna finger in its hand emitted a faint ominous glow.
It was drawing power from it.
The cursed energy around the curse condensed rapidly.
A massive black sphere formed before it.
The air around the sphere warped violently.
Even light seemed to be swallowed.
A pure concentration of cursed energy.
Enough power to level the entire detention center.
Megumi's face turned pale.
"Run!"
"We can't stop that!"
"That thing will vaporize us!"
"Run?"
Yagami Sora stepped forward.
"That word doesn't exist in my dictionary."
He raised his right hand.
Palm facing upward.
"Since you prepared such a grand gift…"
"…I'll accept it."
The black sphere shot toward him.
Wherever it passed—
The floor cracked.
The air burned.
Sora didn't dodge.
His palm met the attack directly.
At that instant—
Time seemed to slow.
His brain entered overdrive.
The system processed information at extreme speed.
Mass.
Velocity.
Energy density.
Rotational momentum.
Cursed-energy wavelength.
Every parameter was calculated instantly.
"Vector…"
"…Reverse."
BOOM—!!!
The black sphere stopped.
Then—
Like a ball struck by an invisible force—
It rebounded upward.
Faster than before.
It shot directly back toward the cursed spirit.
The curse had no time to react.
Its primitive instincts could not understand what had happened.
Its own ultimate attack slammed directly into its face.
The explosion filled the sky like a blazing firework.
A massive cursed-energy storm swept through the hall.
The distorted space trembled violently.
Even the barrier field surrounding the detention center seemed unstable.
Yuji.
Megumi.
Nobara.
All three stared in complete shock.
"…That's insane…"
Yuji whispered.
"A fight between Special Grade sorcerers…"
Megumi muttered.
"…looks like this?"
Kicking the enemy's ultimate attack back like a ball.
That was simply unfair.
