"Berjanjilah padaku kita akan menikah saat dewasa!"
Yuta Okkotsu menyaksikan kematian kekasih masa kecilnya dalam kecelakaan lalu lintas. Rika berubah menjadi roh terkutuk. Dihantui oleh rohnya, Okkotsu ingin mengakhiri hidupnya. Namun, ia dibawa ke Sekolah Jujutsu oleh Penyihir Jujutsu terkuat, Satoru Gojo. Di sana, Okkotsu bertemu teman-teman sekelas barunya: Maki Zen'in, Toge Inumaki, dan Panda, lalu membuat keputusan.
"Aku ingin memiliki keberanian untuk terus hidup!"
"Aku akan mematahkan kutukan Rika di Sekolah Jujutsu."
Di sisi lain, seorang penjahat misterius telah muncul. Dia tak lain adalah Suguru Geto, pria yang dibuang oleh Sekolah Jujutsu karena membantai nyawa tak berdosa dengan kejam. Suguru ingin membangun surga bagi Penyihir Jujutsu dan melenyapkan semua yang bukan penyihir. Dia akan melepaskan seribu kutukan di Shinjuku dan Kyoto. Bisakah Okkotsu menghentikan Suguru sebelum terlambat? Bisakah dia mematahkan kutukan Rika?


“Promise me we’ll marry each other when we grow up!”
Yuta Okkotsu witnessed the death of his childhood sweetheart in a traffic accident. Rika was turned into a cursed spirit. Haunted by her spirit, Okkotsu wanted to end his life. But he was taken to the Jujutsu High by the most powerful Jujutsu Sorcerer, Satoru Gojo. There, Okkotsu met his new classmates: Maki Zen'in, Toge Inumaki, and Panda and made a decision.
“I want to have the courage to live on!”
“I'll break Rika's curse at Jujutsu High.”
On the other hand, a mysterious villain has shown up. He is none other than Suguru Geto, the man banished by Jujutsu High for the massacre of innocent lives in cold blood. Suguru wants to build a paradise of Jujutsu Sorcerers and eliminate all non-sorcerers. He will unleash a thousand curses in Shinjuku and Kyoto.
Can Okkotsu stop Suguru before it’s too late? Can he break Rika’s curse?
