Kagaseo

Kagaseo(天香香背男, Lit. "Supreme Master of The Primordial Void") may very well be the most powerful being in all of conceivable existence. Kagaseo is an ineffable entity whom The Choshin themselves descended from and are connected to. Due to being the god of primordial nothingness, all things are related to and are a part of Kagaseo, which in turn allows him to exact dominance over every form of existence.
