Hi All!
I'm a newbie at this series, and two main questions I have are:
I assume Nagi took a human form that's a reflection of her mind's-eye of her ideal human self (she doesn't really appear much different when she first met young Jin years before), so if true, does the manga or anime give us a hint of what Zange-chan
really looks like apart from Hakua?
I think the longer Zange remains in Hakua's body and shares identical (guided) experiences, it will be an advantage to her to maintain the status quo, especially if her/their stage life becomes highly successful. Zange is very pragmatic and knows staking a place and station in the human world is very beneficial for her ego and powers. Also the corporeal life might be appealling to formally bodiless deity Zange, and a human body's sensory and sensual delights might appeal to her curiosity and taste and preferences. The same might hold true for Hakua, who now has intimate access to a God's experiences and powers. It could even happen that they develop a "parallel" personality after a couple of years which is a de facto merge of sorts, especially since Hakua's still young. By age thirty after such sharing and commonalities, there might be very little difference in the two minds that inhabit Hakua's body, so in effect you'd have a third new "composite" personality there.
Anyway, that's my take! Hope it's not too off the wall!
Take care all!
