High schooler Yuuji Itadori leads a quiet life, spending time in the Occult Club or visiting his bedridden grandfather. His world changes when he unknowingly encounters a cursed item, triggering a series of supernatural events. After swallowing the item—a finger of the demon Sukuna Ryoumen, the King of Curses—Yuuji is thrust into the dangerous realm of Curses, malevolent beings born from human negativity. As Yuuji gains new, powerful abilities, he discovers the deadly threat these Curses pose. Introduced to Tokyo Prefectural Jujutsu High School, he embarks on an irreversible journey as a Jujutsu sorcerer, facing powerful enemies.
