Yuji Itadori, a naturally gifted high school athlete with little direction in life, stumbles into the world of cursed spirits when his school's Occult Research Club unseals a rotting finger belonging to Ryomen Sukuna, the legendary King of Curses. To protect his friends from the swarm of curses the finger attracts, Yuji swallows it — and Sukuna's consciousness awakens inside him. Sentenced to death by the jujutsu world for harboring Sukuna, Yuji is given a reprieve by the sorcerer Satoru Gojo: find and consume all of Sukuna's remaining fingers, then die.
