I discovered this manga years ago and was eagerly waiting for each release. The story features an interesting premise and the art is gorgeous, but and this is a big BUT I hate the big loli factor and the sexualising of the female cast. Don't get me wrong, I don't care much for them being a goth loli or a information broker in a hoodie or whatever, but the leading pictures for each chapter are where I draw the line.
So this is a great read, but if you have a bigger problem with manga-ka sexualizing kids (and not in the panchira kind of way) this could deter you from an otehrwise great manga.
