Psssssst that’s not Hiyori, sorry Yatoti fans (myself included) That’s Izanami, Ebisu’s mother. She’s the queen of the underworld, which is where Yato and Ebisu end up going. She basically takes the form of the person the one looking at her is the most comfortable with, which in Yato’s case is none other than his beloved Hiyori. That’s why he looks uneasy because she tries to get him “out of his comfort zone” if you will with Hiyori’s face. Just wanted to clear the confusion and probably excitement over what seems to be a shipping moment. Sorry for the news.
