The third season of Jujutsu Kaisen. 
After the Shibuya Incident, a deadly jujutsu battle known as the Culling Game orchestrated by Noritoshi Kamo erupts across ten colonies in Japan. 
Haunted by guilt over the mass killings in Shibuya and wary of Sukuna’s interest in Fushiguro, Itadori chooses not to return to Jujutsu High. Instead, he teams up with Choso to exorcise the countless cursed spirits unleashed by Noritoshi Kamo.
Amid this chaos, the Jujutsu Headquarters revokes Yuji Itadori’s suspended death sentence and appoints special-grade sorcerer Yuta Okkotsu as his executioner. 
Newly awakened modern sorcerers and resurrected ancient ones, now fighting as players in the Culling Game, collide with conflicting motives, driving the world once more toward an age ruled by jujutsu.
