Hidden in plain sight, an age-old conflict rages on. Supernatural monsters known as Curses terrorize humanity from the shadows, and powerful humans known as Jujutsu sorcerers use mystical arts to exterminate them. When high school student Yuuji Itadori finds a dried-up finger of the legendary Curse Sukuna Ryoumen, he suddenly finds himself joining this bloody conflict.Attacked by a Curse attracted to the finger's power, Yuuji makes a reckless decision to protect himself, gaining the power to combat Curses in the process but also unwittingly unleashing the malicious Sukuna into the world once more. Though Yuuji can control and confine Sukuna to his own body, the Jujutsu world classifies Yuuji as a dangerous, high-level Curse who must be exterminated.Detained and sentenced to death, Yuuji meets Satoru Gojou—a teacher at Jujutsu High School—who explains that despite his imminent execution, there is an alternative for him. Being a rare vessel to Sukuna, if Yuuji were to die, then Sukuna would perish too. Therefore, if Yuuji were to consume the many other remnants of Sukuna, then Yuuji's subsequent execution would truly eradicate the malicious demon. Taking up this chance to make the world safer and live his life for a little longer, Yuuji enrolls in Jujutsu High, jumping headfirst into a harsh and unforgiving battlefield.
