This show really does have an interesting take on the afterlife. In our society, it’s easy to think of the afterlife as this perfectly ordered place where everyone is judged fairly by some ultimate being. But what if the afterlife is finite like our world? What if there are limitations? Judgments can be bottle-necked by this information bureau and arbiters are judging humans based on having no experience being human. If your afterlife was something like this, would you still want to believe in it?
Anyway, it looks like the point of this show is putting the unnamed human with Decim in order to create a more “human” arbiter, presumably just as part of Nona’s personal experiment. I wonder what’s going on with the people for next week’s episode…what would they need to have to require a specialist?
