Well Satio having Ashera's heart makes sense because Mahiru and Satio worked together and Mahiru once held Ashera in possession so there's chance that Satio has Ashera's heart, but we might be wrong at the same time because the first progenitor said that he will be by his side forever so he may have Ashera's heart. It's a big mystery though, the dissappearance of the first progenitor, why he turned ashera into a demon and Mahiru sealing Ashera into a weapon and turing him into a cursed gear.
