If you think it's a sweet pet, no, it's not. It's sad.
If you think it's an idol drama, no, it's not. Its main line is ghost hunting. If you think its setting is ridiculous, yes, because it has a new world view. If a demon can save all mankind, is it worth saving? If human civilization is lost, will it be replaced by another civilization?
I'm sorry, I shouldn't live in this broken world.
