Curses are born from human fear, hatred, regret, and despair. Most humans cannot see them. They leak cursed energy unconsciously, feeding the very monsters that threaten them.
To combat these manifestations, a hidden society exists:
Jujutsu Sorcerers.
They are trained from youth. They are ranked. They are deployed like soldiers. And they die young.
The balance of this world quietly rests on one individual:
Satoru Gojo — The Strongest.
But the story does not begin with him.
It begins with a boy who swallowed a finger.
Yuji is physically extraordinary but not originally connected to jujutsu. He lives by a simple moral philosophy given by his grandfather:
“Help people. Make sure they have a proper death.”
When a cursed object sealed at his school attracts a powerful curse, Yuji encounters:
Megumi Fushiguro — a jujutsu sorcerer from Tokyo Jujutsu High.
A special-grade cursed object: one of Ryomen Sukuna’s 20 fingers.
Sukuna was once a human sorcerer so powerful that even after death, his remains became indestructible cursed objects.
To save his friends, Yuji swallows the finger.
Sukuna incarnates.
For a moment, the King of Curses stands in the modern world.
But Yuji suppresses him.
This is unprecedented.
Yuji is immediately sentenced to death by the higher-ups.
A Sukuna vessel is too dangerous to exist.
Satoru Gojo intervenes.
He proposes a compromise:
Delay execution.
Have Yuji consume all 20 fingers.
Execute him afterward.
The higher-ups reluctantly agree.
Yuji is enrolled at Tokyo Jujutsu High.
His execution is only postponed.
Yuji trains under Gojo.
He learns:
Cursed energy is negative emotion.
It must be controlled precisely.
Physical strikes must be infused simultaneously with cursed energy.
He develops Divergent Fist — imperfect cursed energy timing causing a delayed second impact.
Meanwhile, Gojo demonstrates to Yuji the overwhelming gap between himself and special-grade curses when he effortlessly defeats Jogo.
This scene establishes a truth:
There are levels to this world.
And Gojo stands alone at the top.
Yuji, Megumi, and Nobara are sent to a juvenile detention center.
A special-grade cursed womb has manifested.
The ranking was misjudged.
Inside, the environment transforms into a domain-like space.
They encounter a newly incarnated special-grade curse.
They are outmatched instantly.
Yuji is killed when Sukuna rips out his heart to gain control.
Sukuna defeats the special-grade curse effortlessly.
But he refuses to restore Yuji unless Yuji accepts a binding vow.
Yuji dies.
For a moment, the protagonist is gone.
In Sukuna’s innate domain:
Sukuna proposes a deal.
Yuji will be revived.
In exchange, Sukuna may take control for one minute when he says “Enchain.”
Yuji will forget the vow.
Yuji refuses at first.
Sukuna kills him again inside the domain.
Yuji eventually accepts.
He revives.
The binding vow is sealed.
This moment will matter later.
Megumi was willing to summon something catastrophic (implied Mahoraga) to survive.
Nobara faced mortality for the first time.
Yuji realizes:
Sorcerers die horribly.
There is no heroism.
Only survival.
Meanwhile, the higher-ups note:
Yuji’s existence is destabilizing.
In the background:
Mahito.
Jogo.
Hanami.
They discuss killing humans and overthrowing sorcerers.
And behind them—
A man with Geto Suguru’s face.
This is Kenjaku, though not yet revealed.
They begin preparing something much larger.
The Cursed Womb Arc establishes:
Yuji is not a chosen hero — he is a ticking time bomb.
The higher-ups value control over morality.
Sukuna is not an ally — he is patiently waiting.
Gojo’s protection is the only reason Yuji lives.
And most importantly:
If Gojo were removed —
Yuji would die immediately.
This is the first quiet setup for Shibuya.
