This scene from Mieruko-chan came out of total left field.
Was there a need for Miko’s father to be a ghost? Probably not. Nevertheless, that is the direction this show went in. And yet, what is that thing hurting? Could it be your heart?
Keep in mind this revelation took place as this giant demon-like creature was just lurking in the background. Or, in other words, something else was going on that was pretty damn distracting. But that’s misdirection for you, and this series pulled it off spectacularly.
