I don't get you guys who clearly know this series got axed and rate it a 1 because of it. it would never have a satisfying ending and that's not the fault of the creator, especially of an adaptation. This ending reads like the comic it was serialized in went under, which doesn't seem to be the case. I guess LN publishers didn't want to split their budget on this and the anime at the same time. Hate to break it to you but adaptations are most of the market in manga, anime, and even Light Novels, which you can check on the chapters page.
I really like this story and I guess I'll got watch the anime and see how its going. That's at least a fully planed production so it won't just end in a sudden way.
