Kingdom of Skulls

Kingdom of Skulls (頭蓋骨の王国, Zugaikotsu no Ōkoku), is a Caster Magic and a dangerous and powerful form of the Black Arts created by Macabrenus Goetion some generations ago; it's part of the Death God Triad (, Desu Goddo Toraiado; lit. "Three Reaping Scythes of the Underworld") — serving as part of the reason he's known as the "Ferryman of the Underworld" (黄泉渡し守, Kousen Watashimori), amongst the previous and current generations of the Spriggan Twelve. It serves as one of his signature magics, alongside The Sinner's Golgotha, and most recently — Memento Mori.

It's one of the few magics that makes use of Magical Barrier Particles, molding its entirety into something similar to a Curse; this is ironically fitting, as its creator has been called a Demon on various occasions by his allies and enemies alike. Due to its effects, it's considered to be a Subspecies Magic — deriving from Death Magic.
