Sorcery Boosters (ソーサリー・ブースター) are described as breakthrough magic amplifiers that illegally went into production several years prior to the main story. The criminal organization, No Head Dragon, is believed to be responsible for their development and is heavily involved in their distribution. Each booster is specifically designed to use one type of magic, so the type of magic that can be used by the magician differs based on the booster's specifications.
