Reception
In the time that it has been released, the manga has received overall criticism by fans, although there are some that feel it's a great adaptation to the original game. Most of the fans criticize it for a variety of reasons. Some aren't exactly in favor of the new art style. Others heavily dislike the fact of a new story. Rather than only Madotsuki's story, Poniko's and Masada's are being told. Another change was that the story was told with dialogue, as opposed to the original which was all about the player's interpretation. There are many other reasons.
