I’m looking for a novel where the protagonist is a ghost. I would like a world with a similar power structure of Lord of the Mysteries. Rather they not be a pervert. also an adult instead of a teenaged ghost would be a plus.
I know only this with ghost/soul protagonist https://www.novelupdates.com/series/two-as-one-princesses/
https://www.novelupdates.com/series/mulberry-song/ Is a josei shortstory, so it might not be what you're looking for.
