This is the first volume of a series of manga, but unfortunately, it didn't really feel like it stands on its own. As an origin story, it's rather slow-paced and repetitive. The flashbacks were confusing at first, but I eventually became used to them and understood the way the story was being told. My main problem is, I'm not sure this volume is compelling enough to make me want to read the next. I kept hoping we would find out the meaning behind the cult and its leader, but that is clearly one (or more) volumes away. I feel the germ of an interesting story is here, but I'm not seeing quite yet.
