I don't get the sentiments that readers are supposed to see one group or any character as ugly. To me, those are just prejudices and insecurities voiced by the various characters. We're not meant to believe them but maybe just to believe that Kurokawa and others have assimilated those views.
I have zero tolerance for bullying, so I'd like to see the redemption theme pushed further with Fujishiro; however, I agree with others that its already more believable and respectable than what we usually see in manga of this genre. No one's perfect. Kudos to the author for not having her magically lose her brash ways.
I personally prefer to be around people who speak their minds, even if what they say isn't always "nice" by societal norms. But there's a difference between being frank and bullying. (I like Fujishiro's character until I revisit the first chapter.)
On a different note, Kurokawa's character was extra pathetic this chap. Hopefully the next update does something for her while also giving some sign of plot development. Sheesh. At least the panels still look good.
