No, World’s End Harem is not just another controversial NSFW anime show, it has so much potential that the story is definitely going somewhere other than the desires of the people having to copulate. It’s the right mix of a mystery and some fun in between but is it based on something like a manga or a light novel? If so, what is the status of it?
