I don’t think y’all read the first chapter properly. Oyuki was on the verge of death and that’s when Tama found her body. Oyuki willing let Tama take over her body and her soul went to heaven so to make things clear her body wasn’t dead she just choose to leave her body and give it to Tama beside Mutsu mentioned Tama is a weak demon she is unable to take over someone’s body if they didn’t willing give it up
