The Grip of Murder (in Japanese: 呪術「殺戮の兇手」 Jujutsu: Satsuriku no Kyoushuu; Sorcery: Evil Hand of Slaughter) is an ancient, alchemical Slavic curse that poisons and kills its infected victims with the increasing hatred and malice of people they murdered and it is used by the Regent of the Mask, a dangerous high-ranking member of a powerful cult of modern-day alchemists known as the Lords of Alchemy. Also another skilled spellcaster among the ranks of the Lords of Alchemy is the cult's charismatic leader and Cliff's grandfather Ashtear Higgins who too is capable of mastering the Grip of Murder and he will not hesitate to inflict it upon those who would dare to oppose him and his followers.
