Ah-Ungyo Prayer

Ah-Ungyo Prayer (阿吽形祈念, Aungyō Kinen) is a powerful form of Onmyōdō unique to the Spriggan, God Serena — being one of the highest forms of summoning known to the arts; it's also considered to be the only one he knows, having no interest in said art in lieu of his immeasurable talent in it. Even amongst other Onmyōdō forms, it's incredibly powerful and versatile, having a myriad of uses — further denoting to the man's prowess.

According to him, the magic is a personification of his "godly" nature, believing that one should have as many retainers to match such a position — common trait known to all worshipped deities. To this extent, he alternatively calls this magic Godly Servant Manifestation (神人僕表明, Shinjinboku Hyōmei) — another example of his hubris; despite such naming, it proves the Spriggan's justification as a powerful magic.

Recognized as a Caster Magic, it's a Subspecies Magic of Ceremonial Manifestation Magic — another form of Onmyōdō, utilizing its foundations to bring forth such powerful familiars to fight on the Spriggan's behalf. Due to its usage, it's considered to be an unorthodox fighting style. Regardless, this magic is considered to be one of God Serena's most used — nearly matching his Naturion Rampage, his signature.

Overview
"Y'see?! Even the Gods bow down before my presence and come at my beckon call! It's a clear sign that I'm one to be feared, something that should be forever drilled into the core of your being as you're slowly destroyed by these divine servants of mine!"
