Cursed Spirits (呪じゅ霊れい, Jurei?), or simply Curses (呪のろい, Noroi?), are a race of spiritual beings invisible to humans, incarnated from the cursed energy that leaks out of humans over time due to their negative emotions. Cursed spirits haunt and bring harm to humanity and are consequently the primary targets of jujutsu sorcerers and their exorcist work.
