Jujutsu Kaisen is a Japanese manda/anime series that follows the story of high school student Yuji Itadori, as he joins a secret organisation of Jujutsu Sorcerers in order to kill a powerful Curse named Ryomen Sukuna, of whom Yuji becomes the host.
This Pop! features Satoru Gojo, a special grade jujutsu sorcerer and widely recognised as the strongest in the world. Satoru is the pride of the Gojo Family, the first person to inherit both the Limitless and the Six Eyes in four hundred years. He works as a teacher at the Tokyo Jujutsu High and uses his influence to protect and train strong young allies.
He comes here unleashing the Hollow Purple technique, which is the fusion of both Red and Blue, a secret ability known to only a few in the Gojo Family. It represents motion and reversal, a fusion of convergence and divergence that collides both infinites to generate an imaginary mass. The effect takes the target out of reality, instantly erasing everything the technique hits without exception. So as you can see, it's kind of a big deal.
