While Yuji Itadori trains under Satoru Gojo, a new threat moves in the shadows.
Mahito is a special-grade cursed spirit born from humanity’s hatred of other humans. Unlike Jogo, whose existence embodies fear of the earth, Mahito is fascinated by the human soul. To him, humans are raw material. Their forms are clay. Their pain is curiosity.
He believes the shape of the body is determined by the shape of the soul.
With a single touch, he can reshape it.
This ability is called Idle Transfiguration.
Junpei Yoshino is a high school student isolated and bullied by his classmates. He is intelligent, withdrawn, and harbors deep resentment toward the cruelty of others.
One night at a movie theater, Mahito slaughters several humans in front of him using transfigured humans. Instead of killing Junpei, Mahito engages him in conversation.
Mahito nurtures Junpei’s bitterness.
He presents himself as someone who understands hatred.
Junpei, alienated and angry, begins meeting Mahito in secret.
Meanwhile, Grade 1 Sorcerer Nanami Kento investigates the theater incident.
Nanami is a former salaryman who returned to jujutsu society. He operates by strict logic and professionalism, believing overtime work is irrational and sorcerer life is cruel but necessary.
Yuji is assigned to assist him.
Nanami explains to Yuji:
Sorcerers are not heroes.
They are technicians managing disasters.
During the investigation, Yuji encounters Mahito for the first time.
Mahito unleashes transfigured humans.
Yuji instinctively fights with overwhelming physical strength.
When Yuji lands a punch infused with cursed energy, Mahito experiences something unexpected.
Yuji can strike his soul directly.
Because Yuji houses Sukuna, his understanding of the soul is unconsciously deeper.
Mahito retreats, intrigued.
For the first time, he feels fear.
Mahito manipulates Junpei further, encouraging him to act on his hatred.
Junpei poisons his classmates during a school assembly.
Yuji arrives to stop him.
Instead of fighting, Yuji tries to understand him.
Junpei hesitates.
He considers change.
Mahito appears.
In front of Yuji, Mahito touches Junpei’s shoulder.
Junpei’s soul is twisted.
His body grotesquely transforms.
Yuji screams for Sukuna to heal him.
Sukuna refuses.
Junpei dies in agony.
Mahito laughs.
This is Yuji’s first irreversible failure.
He could not save Junpei.
He could not force Sukuna to help.
He could not prevent death.
For the first time, Yuji feels genuine hatred.
He declares:
“I’ll kill you.”
Not as a hero.
Not as a savior.
But as executioner.
Nanami arrives to assist Yuji.
Nanami’s technique, Ratio Technique, allows him to create weak points at a 7:3 ratio on anything.
He overwhelms Mahito initially.
However, Mahito begins evolving mid-battle.
He learns rapidly.
He begins reshaping himself creatively.
The battle escalates into Mahito’s Domain Expansion:
Self-Embodiment of Perfection
Inside, any contact guarantees Idle Transfiguration.
Nanami is cornered.
Yuji breaks into the domain from outside.
Because Sukuna resides within Yuji, Mahito cannot touch Yuji’s soul without risking Sukuna’s retaliation.
Mahito is forced to retreat again.
Mahito realizes something fundamental:
Humans and curses grow through conflict.
He matures emotionally during battle.
He begins viewing Yuji as his natural enemy.
Not ideologically.
Existentially.
Behind the scenes, Mahito reunites with:
Jogo
Hanami
Choso
The man wearing Geto’s body
They discuss the larger objective.
The goal is no longer random chaos.
The goal is structural disruption.
And they identify the greatest obstacle:
Satoru Gojo.
Mahito acknowledges that they cannot defeat Gojo directly.
They must separate him.
During this arc, Gojo remains untouchable.
When Jogo previously attempted to kill him, Gojo demonstrated overwhelming superiority:
Infinity made him unreachable.
Unlimited Void paralyzed Jogo instantly.
He treated a special-grade curse like a training dummy.
The curses understand:
As long as Gojo exists, their revolution is impossible.
The idea of sealing him begins to take shape.
Junpei’s death reshapes Yuji’s philosophy.
He accepts:
Some people cannot be saved.
Curses must be eliminated.
Nanami sees potential in Yuji but recognizes the emotional burden he carries.
Mahito continues to experiment, refining Idle Transfiguration.
The alliance solidifies around a singular long-term plan.
The stage expands beyond individual tragedy.
The conflict is no longer isolated missions.
It is becoming a war.
