So instead of separating the sexes why not just make some people infertile (namely the poor)? This manga makes no damn sense what gain could you get from separating the sexes into different sections. You have these metropolis but you can't figure out how to make some people infertile so men and women can live together in the same bubble? So much of this manga makes no sense to me you could tell this was 19 year old Kentaro trying to think of something fantasy wise I would've loved to have seen Kentaro do a scifi cyberpunk manga but sadly that will never come tofruition.
