Basics

 * curse (呪い) General term for the negative energy stemming from the emotions of humans. It can also refer to cursed spirits.
 * cursed spirit Spiritual monster that is formed from the cursed energy that leak out from regular non-sorcerer humans. Like sediments that clump together and gain sentience. Thus, they accumulate in places with bad memories (e.g. schools and hospitals). Large negative feelings toward the same concept or idea will also form Curses. In Japan, the average number of mysterious deaths and missing persons exceed 10,000 annually are caused by cursed spirits. Also referred to as simply, Curses.
 * cursed energy Power source resulting from negative human emotions. Used by sorcerers and cursed spirits to fuel their jujutsu. Can be used to reinforce the user's body.
 * cursed object Item with a dark history that contains cursed energy. They generally consist of the remnants of ancient people. The objects have commonly been used as a protective ward against lesser cursed spirits.
 * cursed tool Support items used by jujutsu sorcerers that are already imbued with a curse.
 * exorcism Using cursed energy to get rid of a cursed spirit. Since their bodies are composed of cursed energy, cursed spirits cannot be harmed be removed with purely physical attacks.
 * grade Ranking system in place for all jujutsu users and related items that scale them from the lowest: Grade 4 to highest: Special Grade. These include sorcerers, cursed spirits, cursed objects, and Cursed Tools.
