I have to say I'm surprised at the high ratings and praises. The art is good for sure and the subject matter is interesting and fairly unique, but the story is just abysmal to me. Berserk, vinland saga, ASOIAF and the rest are maybe similar in style, but just miles apart from this one in quality, imo. I kept asking myself over and over where the point was, where the motivation was, and where the personalities were. The main villain is especially 2d, but the protagonists weren't much better. They all had the same story, they just looked different. It kinda felt like shock and gore for its own sake, and that's just not enough for me.
Not to mention all the asspulled deus ex machinas (or maybe diabolo ex machinas in this case). At no point were we given prior clues to the plot points, at no point is it explained how or why the villain was so good at his job. It was like watching Sherlock, but without following his process. He just steps out and goes "you did it", case closed. Not very interesting, intriguing, or satisfying storytelling in my book.
There, rant over. Not trying to take anything away from those that like it, I just had to vent.
