Before October 31st, the hidden traitor within Jujutsu High makes his final move.
Kokichi Muta, known as Mechamaru, had secretly cooperated with the curse alliance. Born with a Heavenly Restriction that left his body frail and immobile, he bargained with Mahito:
Information in exchange for healing.
However, he never intended to betray humanity fully. Once healed through Idle Transfiguration, he attempted to eliminate Mahito and warn Jujutsu High.
He deployed an arsenal of remote-controlled cursed puppets and a massive stored cursed energy construct designed specifically to kill Mahito.
Mahito evolved mid-battle.
He unveiled his perfected form and Domain Expansion.
Mechamaru was killed.
Before dying, he activated contingency communication devices to alert Gojo and the others.
But it was too late.
The operation had already begun.
At 7:00 PM, multiple massive curtains descend over Shibuya.
The barriers serve layered purposes:
Trap civilians underground.
Prevent sorcerers from entering.
Specifically allow Satoru Gojo through.
A message spreads among trapped civilians:
“Bring Satoru Gojo.”
The enemy understands his psychology.
He will come alone.
Gojo arrives at Shibuya Station.
The underground platforms are packed with thousands of civilians.
He cannot use large-scale destruction techniques.
Immediately, he is confronted by:
Jogo
Hanami
Choso
Transfigured humans
The curses do not attempt to overpower him directly.
They stall.
They rotate attacks.
They force him to protect civilians.
Gojo demonstrates overwhelming superiority even under restriction.
He dodges, counters, and disables Jogo and Hanami effortlessly.
However, Mahito floods the station with transfigured humans.
Gojo refuses to abandon civilians.
He refrains from using Hollow Purple.
The battlefield becomes a test of precision.
Realizing conventional combat will not end the stalemate, Gojo activates:
Domain Expansion — Unlimited Void
But only for 0.2 seconds.
Inside the domain, targets are overwhelmed with infinite information.
Even 0.2 seconds paralyzes civilians for months.
Gojo calculates precisely.
He incapacitates all transfigured humans simultaneously.
He then instantly eliminates Hanami.
Jogo survives but is gravely wounded.
For a moment, victory appears certain.
Then he arrives.
Suguru Geto stands before Gojo.
Alive.
Gojo freezes.
Six Eyes analyze:
The body is authentic.
The cursed energy is authentic.
The presence is real.
Yet something is wrong.
Gojo demands an explanation.
The man smiles.
He removes the stitches across his forehead.
The brain within speaks.
He introduces himself:
An ancient sorcerer.
Later known as Kenjaku.
He reveals:
He transplanted his brain into Geto’s corpse after Gojo killed him.
The Prison Realm descends.
Activation condition:
The target must remain within four meters for one minute of perceived time.
Gojo is immobilized not physically —
But psychologically.
Memories flood back:
Riko’s death.
Geto’s defection.
Their final conversation.
Killing his best friend.
He processes the impossibility.
The shock.
The betrayal of reality itself.
One minute passes inside his mind.
The Prison Realm activates.
The cube closes.
The strongest sorcerer vanishes from the battlefield.
The curses retreat.
The balance of the world shatters instantly.
With Gojo gone:
Cursed spirits surge globally.
Sorcerer command structure destabilizes.
The higher-ups lose their greatest deterrent.
The battlefield descends into chaos.
But the night is far from over.
Shibuya continues burning.
The sealing of Gojo accomplishes what no enemy could achieve through force.
It removes the axis of stability.
For years, every crisis had an ultimate solution:
Call Gojo.
Now there is none.
The curse alliance transitions from harassment to annihilation.
What follows is massacre, escalation, and irreversible loss.
But the turning point — the moment history fractures —
Is the second the Prison Realm closes.
Everything leading here mattered:
Riko’s death created emotional vulnerability.
Geto’s body provided the perfect disguise.
Mechamaru’s failed resistance prevented warning.
The Goodwill Event proved coordinated curse strategy.
Yuji’s survival ensured Sukuna remained in play.
The higher-ups’ rigidity weakened unity.
The sealing was not an accident.
It was engineered across years.
And it succeeded because Gojo hesitated.
Not out of weakness.
But because he was human.
