This is the number 2 rated manga (novel tho) on myanimelist.net, it's been really good so far! For some reason like no one has read it even though it's so good. I was wondering if anyone else here has? I mean it's so interesting because it's so different and unique, I've never read anything like it. The description on Mal says nothing about what this novel is actually about, so don't base any opinions on that if you are thinking of reading it.
