Yuji Itadori, a seemingly ordinary high school student, possesses extraordinary physical strength that catches the eye of every sports club. However, he prefers to spend his time with the school's outcasts in the Occult Research Club, engaging in baseless paranormal activities. One fateful day, Yuji encounters a cursed item when the club unseals a mysterious object, unknowingly triggering a chain of supernatural events that thrusts him into the dark world of Curses—malevolent beings born from human negativity and malice. In a desperate attempt to save his friends from these terrifying entities, Yuji swallows the cursed item, which is later revealed to be the finger of Sukuna Ryomen, the infamous King of Curses. This act binds Sukuna's soul to Yuji's, forcing them to share one body. Guided by the powerful sorcerer Satoru Gojo, Yuji enrolls in the Tokyo Prefectural Jujutsu High School, an institution dedicated to training sorcerers to combat Curses. As he begins to walk the path of a Jujutsu sorcerer, Yuji realizes that he can never turn back from this life, embracing his newfound powers to exorcise Curses and protect the innocent. Thus begins the heroic tale of a boy who becomes a Curse himself to fight against the very entities that threaten humanity, learning the true meaning of "the right death" along his perilous journey.
