Before the Shibuya Incident, a girl’s cursed energy awakens after her mother dies in a car accident—drawing the attention of the higher-ups, who handle her brutally and discard her when she proves too unstable. Left beaten at the gates of Tokyo Jujutsu High, she’s taken in under Satoru Gojo and his students, including Yuji Itadori and Megumi Fushiguro. But her cursed energy behaves in unnatural, reactive ways—marking her as something far more dangerous than a typical sorcerer, and a problem the higher-ups may not be finished with.
