Since the very beginning of Jujutsu Kaisen, one sorcerer alone has reigned supreme in the verse. Prevailing in every battle that comes his way, defeating opponents without breaking a sweat, and having so much power he can influence even the Jujutsu elders, Gojo Satoru is well and truly an unbeatable force. He is the pinnacle of strength in the series. Gojo is a role model every jujutsu sorcerer admires, and the sorcerer all curses or cursed users fear running into.
