Fans have spotted a familiar face in the lineup of Jujutsu Kaisen's second season, as this is not Geto Suguru's debut in the popular anime. The curse user was the main antagonist of the hit film Jujutsu Kaisen 0 but overall has remained a bit of a mystery, especially considering teenage Geto is a kind-hearted, considerate sorcerer. This varies massively from the villain status he achieved while fighting Yuta, Maki, and other jujutsu high students.
