Jujutsu Kaisen 0 (Complete Guide, Story & Characters)
Jujutsu Kaisen 0 is the official prequel to Jujutsu Kaisen, created by Gege Akutami.
It was originally published as Tokyo Metropolitan Curse Technical School and later renamed to connect it with the main series. This prequel is essential because it introduces key characters, explains the power system, and sets up major events that influence the main storyline.
Jujutsu Kaisen 0 Story Summary
The story begins with Yuta Okkotsu, a deeply troubled high school student who is haunted by a powerful cursed spirit, his childhood friend Rika Orimoto.
Rika is not an ordinary curse. She is extremely violent and protects Yuta at all costs, often harming anyone who gets close to him. Because of this dangerous situation, Yuta is taken in by Satoru Gojo, the strongest jujutsu sorcerer, and enrolled at Tokyo Jujutsu High.
Through training and missions, Yuta slowly learns to control his cursed energy and accept Rika’s presence instead of fearing it. At the school, Yuta meets fellow students:
- Maki Zenin – a skilled weapon user with no cursed energy
- Toge Inumaki – a sorcerer who uses cursed speech
- Panda – a unique cursed corpse with emotions
The Main Conflict – Yuta vs Geto
The central antagonist of the story is Suguru Geto, a powerful curse user with a radical ideology.
Geto believes that only jujutsu sorcerers should exist, and he plans to eliminate non-sorcerers to create a new world. To achieve this, he targets Yuta, intending to take control of Rika, one of the most powerful cursed spirits ever known.
This leads to an intense final battle between Yuta and Geto, where Yuta fully embraces his power and unleashes Rika’s true strength.
