Arcanemagoria

Arcanemagoria (兇暴積悪の変幻自在具現 (アーケインマゴリア), Ākeinmagoria; lit. "Phantasmagorical Embodiment of Myriad Atrocious Sins") is considered to be one of the more powerful forms of Caster Magic and a very infamous form of the Black Arts; what makes this magic unique is that it's usable only by Demons — acting as one of their most powerful weapons at their disposal. It's commonly seen as the antithesis to Angel Magic and has close ties with Devil Magic, the latter of which is believed to be its twin counterpart due to their parallel origins.

Due to the nature of this unique magic, it's considered to be a form of Subspecies Magic — deriving from the basic concepts of darkness element, something that's synonymous to Demons. However, due to the immense amounts energy needed to utilize such a destructive force, it's usable by a select few. For those who've witnessed this magic's might first-hand, it's been dubbed as the "Hell's Guardian" (陰府の護者, Yomi no Hogosha); it's one of the few magics that's able to counter the Holy Relics of the Zentopian Church, which are known to be the bane of all forms of evil.
