Chapter 1

Megumi Fushiguro hunts a powerful cursed object at Sugisawa Municipal High School, where Yuji Itadori's tangled club affiliations threaten to shut down the Occult Research club. After a last visit to his dying grandfather, Yuji is told by Megumi that a special grade curse endangers the campus and its students. The two return to fight off the spirits, but a stronger entity overwhelms them and wounds Megumi. Moved by his grandfather's final wish, Yuji devours the cursed object to gain power, and rather than dying, he is transformed when the object incarnates inside him.

Sent to Sendai City to retrieve a special grade cursed object, Megumi finds an empty shed and phones his teacher, who only laughs and orders him not to come back empty-handed. At Sugisawa High, Yuji and his clubmates Setsuko Sasaki and Takeshi Iguchi tease the student council president, who threatens to dissolve the club. Their numbers fall short until the track coach reveals he secretly enrolled Yuji, hoping to claim his freakish athletic talent. Yuji wins a shot put challenge with ease, hurling the ball thirty meters. Meanwhile, Megumi senses a grade 2 curse perched over the rugby field and suspects a connection to the object hidden at the school.

Yuji visits his grandfather at the hospital, where the old man's parting words urge him to help others and die surrounded by people. Megumi confronts Yuji in the lobby, explaining that a worn talisman has unsealed a danger. The hidden object turns out to be a finger belonging to a mighty curse, and it draws spirits to Sasaki and Iguchi. Megumi summons his Divine Dogs through the Ten Shadows Technique but arrives too late as the two are overtaken, then is wounded and thrown outside by the stronger curse.

Because a curse can only be expelled by another curse, Yuji's bare-handed strikes prove useless. Determined to spare everyone a gruesome death, he eats the cursed finger to obtain cursed energy. Megumi expects him to die instantly, noting the one in a million chance that the object would incarnate instead. Yuji transforms and obliterates the attacking curse, leading Megumi to realize that Ryomen Sukuna has been reborn. Sukuna craves the slaughter of all humanity, yet Yuji's will reasserts control over his own body. Unwilling to risk it, Megumi declares he will exorcise the curse now called Yuji Itadori.
