King Magic

King Magic (国王魔法 Kokuō Mahō) is a Caster, Lost Magic which is in the category of Black Arts utilized by the Demon, Regis.

Description
King Magic is a form of magic exclusive to Regis. It is regarded as one of the most devastating forms of Black Arts to exist, simply due to the tremendous exertion an opponent can feel by being exposed to it. Regis is thought to be the embodiment of this very magic into a physical form, which is channeled through his usage of this magic. It is a magic that is derived from Zeref's own persona, taking upon both a physical and magical form, the former being Regis and the latter being this magic. Simply put, King Magic is one that causes authority to be placed unto any being in known existence, by creating what is regarded as a "Sovereignty Chain" (主権鎖 Shuken Kusari). Utilizing one's levels of Eternano as a basis, Regis is able to create a number of individuals in a chain of "sovereignty", which then dictates their limits and strengths. Regis' usage of this magic, simply put, causes everything that is below him in the chain (which is mostly everything) to become one of his "subjects". Becoming his subject causes a mental distortion within his opponents, and through the enormous difference in Eternano levels that is further accentuated through this magic, Regis causes the mind and body of the opponent to be completely submitted to his own will. As long as he is able to maintain a difference in magical energy, whether it be through the exertion of an aura or otherwise, this submission will retain. Yet there is one weakness outside of this simple weakness, in that if an individual from outside of the prescribed chain by Regis enters the scene and exerts their magical energy to counteract Regis' own influence, the effects of King Magic will be dispelled.
