That's because it's effectively an advertisement for the light novel, which apparently only ended recently.

So nothing was really resolved, and that's how it ends? Was this axed?
Overall I'd say the whole manga was 8/10 for me, but just for that ending it went to 6/10. I mean come on, something like that isn't a proper ending.
