Cursed energy is a concept from the world of Jujutsu Kaisen, a popular manga and anime series. It refers to a form of negative energy generated by human emotions, particularly fear, anger, and sadness. This energy can manifest in various ways, often leading to the creation of cursed spirits, which are malevolent entities that feed on this negativity. In the series, skilled individuals known as Jujutsu Sorcerers harness cursed energy to combat these spirits and protect humanity. They can manipulate this energy for various techniques, allowing them to exorcise curses and defend against supernatural threats. Understanding cursed energy is essential for both sorcerers and those affected by curses.
