A small figure—Yuta Okkotsu, returned from Africa—steps over a corpse. "Gojo-sensei... I'm coming." Episode 10: "The Sound of Collapse" The end of an era.

The season’s tone shifts. Geto begins secretly questioning everything. The fall of a hero

Gojo, clinically dead for a few seconds, experiences a vision of the universe's core. He understands the essence of cursed energy— reverse cursed technique . He heals himself. When he confronts Toji again, he is no longer arrogant. He is absolute . Purple light—Hollow Purple—erases Toji in an instant.

Kenjaku (the ancient curse possessing Geto’s body) activates the "Shibuya Incident." A veil traps millions inside the busiest crossing. Gojo arrives—cocky again, but sharp. He exorcises curse after curse. But Kenjaku unleashes the Prison Realm —a cube that can seal anything, even infinity.

Kenjaku gives a chilling speech to the surviving curse users: "The age of sorcerers is over. The age of evolved humans begins."

The antagonist: Toji Fushiguro, the "Sorcerer Killer"—a man with zero cursed energy but inhuman physical prowess. He attacks without warning. Gojo, overconfident, is stabbed through the chest. As he falls, Toji whispers, "The strongest? You're just a talented brat." Gojo’s rebirth. Geto’s first crack.

Nobara lands a critical blow on Mahito’s soul—but Mahito touches her face. Her left eye explodes. She falls, smiling faintly. "I did good, didn't I?" Yuji loses both his mentor and his friend in minutes. He goes berserk, black flashes erupting.
