The thing that I remember most distinctly from this series is the really ugly artwork. Like, this artist's style is terrible. I can barely remember the story (only that I found it tedious and boring and pointless) but the ugliness of everything has never faded from my memory.
I could honestly pick apart the style because it's horrendous on every front. Everyone looks weird and uncanny. I checked the first and last chapters and the author's only real style change is that she used really fat lines at first and then got to using thinner, more sketch-like lines, but the anatomy and weird, huge, bug-like eyes and terrible aesthetic remained.
Since manga is a visual medium, the art plays a big role and for me, a very ugly style will kill any possible merit the story may have had, which is why I maybe got 3-4 volumes into this before I couldn't take it any longer and trashed it.
It may seem harsh, but this manga has the ugliest style I've ever seen that wasn't deliberately made to be ugly and cartoonish, like a lot of gag or children's manga.
