I think episode 8? I'm intrigued by Bishamon and her horde of regalia (how does she command so much loyalty?), and I am shipping Hiyori/Yukine/Yato OT3. (I also liked Hiyori's mortal friends from the opening episodes and wish they'd turn up again, but I suspect I'm out of luck on that.)

I do spend a lot of time being concerned about what happens to Hiyori's body while she's off gallivanting as a spirit, though. She seems to just leave it lying in the street an awful lot.
