As I see it, though, that’s about where the similarities end. Where do humans (within the context of this series) go when they die? Do they end up in “Heaven” (the Sky World), where Elmina’s father rules? Will they end up in the ghost/spirit world? Or do they simply no longer exist? What about when someone from any of the other world dies?

To me, calling the Sky World “Heaven” suggests that “people from other worlds come to this world when they die”.

Likewise, it being “Heaven” suggests that Elmina’s father created everything, and has been around forever. Rather, I’m guessing he was born something like 50 or so years ago, and his father was king before him.

That’s where I get a “misleading” feel from it. A viewer can make assumptions about the world and characters.

That said, the Sky World undoubtedly was based on the Christian concept of Heaven, so it’s understandable for them to use that name in the English dub.

I’m kind of a literal person, so when I hear the Sky World dubbed as “Heaven”, I get this feeling like anyone watching only the dub will believe it’s supposed to be exactly the Christian concept of Heaven, with Elmina’s father being the Christian God. I’m sure anyone watching the series only in English will realize it’s not literally the same.
