i just write what i think about the reveals
theory 1: first inari is killing parents of kitsune to raise there childrens as there loyal servants
theory 2: mc is nt a ghoul hybrid but a full ghoul at least thats what i understood from the last chapters.
a ghoul is created by a ghoul flame put into a human, the stone he has is also a ghoul and has a flame
so maybe it was an accident that he got turned into a ghoul ? or his parents experimentet with it?
so he looks human and is still strong is cause his flame is frome the stone
