In the world of Jujutsu Kaisen, power meant cursed energy.
And Toji Fushiguro had none.
One evening, Toji was walking down a quiet road with his small son, Megumi Fushiguro. The sky was orange, the wind calm. Megumi held his father's finger tightly.
"Dad… will I become strong?" Megumi asked.
Toji glanced down at him. "You already are."
For a rare moment, Toji felt something close to peace.
Then the atmosphere changed.
Four sorcerers stepped out from the shadows, their cursed energy thick in the air.
"That child belongs to the Zenin bloodline," one of them said coldly. "Hand him over."
Toji smirked. "Try taking him."
In an instant, the road turned into a battlefield. Toji moved faster than sight. One sorcerer fell with a broken neck. Another collapsed with a blade through his chest. But while protecting Megumi, Toji's movements slowed for a split second.
A barrier technique activated.
Just for a few seconds.
And those seconds were enough.
When Toji shattered the barrier, the sorcerers were already fleeing with Megumi.
Toji chased them into the forest.
He found them.
He killed them.
But he was too late.
Megumi lay motionless on the cold ground.
For the first time in his life, Toji didn't feel anger.
He felt emptiness.
He lifted his son's small body into his arms and looked at the sky.
"They killed you… because of cursed energy."
His expression changed.
Cold.
Dead.
Final.
"Then I'll kill every sorcerer in this world."
That night, the man with zero cursed energy made a vow.
And somewhere far away, the strongest sorcerers felt it—
A hunter had chosen his prey.
And the Sorcerer Killer had begun his war.
