What could easily be a generic BR rip off quickly becomes something different as it steadily adds to what is happening. At first it looks like a general shonen, but has a surprising level of unreliable narration and people lying to themselves. It even plays with formalistic structure in a way similar to what some of the 80s DC mature titles did. Even something as simple as exposition can be delivered with a constant series of crosscuts and scene jumps which wouldnt even quite work in film. It really takes the medium as far as it can.

And thats all before the issue of the flowers comes up. Basically, this is a ero guru masterpiece. Worth reading for the character design and mutations and bodily warping/destruction alone.
