After a cursed spirit incident that provoked your cursed technique to awaken, you become noticed by Jujutsu Tech and you're offered to join. If you do, you become a Grade 4 sorcerer at Tokyo Jujutsu High. If you don't join, you become a curse user and work against Jujutsu Tech.

Your faction and cursed technique are up to you. Protect people from curses or destroy people with them.
