The start of this manga was a little bit puzzling, throwing us immediately in a dark, mysterious world, and then it got better and better with time. The plot, the characters' development, the twists (oh, how I love those mesmerizing plot twists) and the art are extremely well-made and perfectly thought out.

And then there's the end.
It's unfitting for such a great story in my opinion. It looks extremely rushed to me and ... "narrow". I expected either a more open end or a much more developed one. It leaves me with an unfinished taste.
Too bad, it could have been an amazing 10/10 if not the disappointing end.
