Jogo
The main foe in the Jujutsu Kaisen series is Jogo. He was a particular grade-cursed spirit of undeclared alignment with Mahito, Hanami, and Dagon. Jogo envisioned a society where his kind ruled the planet and thought curses were the real humanity. His arrogance characterized Jogo as a cursed spirit. He was wise, firm in all his convictions, and willing to offer his life for long-term success.
One of many unregistered special grades that surfaced in 2018 was Jogo. He was created as a result of humankind's apprehension of and hostility toward volcanoes and other fire-related natural calamities. As a result, a cursed spirit with exceptional intelligence and levels of cursed energy was created.
He is an immensely strong Curse, with as much cursed energy in him as eight to nine of Sukuna's fingers. Jogo can incinerate opponents in a matter of seconds with his variety of fire and lava strikes.
His Ember Insects let him accurately attack his opponent at a distance while his Disaster Flames Technique generates mini-volcanoes that erupt and destroy anything they touch. Any ordinary sorcerer stuck inside his Domain Expansion: Coffin of the Iron Mountain would be instantaneously engulfed in flames.
Jogo was extraordinarily quick and managed to get past numerous grade 1 sorcerers. Before they could react, he blitzed Nanami and Maki one after the other, lighting them both on fire. One of the swiftest jujutsu sorcerers, Naobito, was even outmaneuvered by Jogo, who then burned him to death.
