Jogo, a Special Grade cursed spirit in Jujutsu Kaisen, possesses the highly destructive innate technique called Disaster Flames. Disaster Flames allow Jogo to manipulate flames in both short and long-range applications, instantly killing normal humans and critically injuring curse users and Jujutsu Sorcerers.
He was born of humanity's fear and negative association with volcanoes and other fire-related natural disasters. This resulted in a highly intelligent cursed spirit with massive levels of cursed energy even for a special grade.
