Oh God, I'm positively salivating at the image of her running head-first into this particular brick wall. Kudou is going to serve her the most magnificent humble pie conceived by man. The look of sheer, undiluted, perfect contempt on his face as he walked past her... A cockroach (aka the insect so detested by the Japanese that it gets mosaic censored in manga) could only dream of inciting that much disgust. I hear the cockroach union has already inquired into whether she would be available to teach lessons.
I suppose her mother is even worse since she's effectively created this monster, so I hope whatever Kaya gets herself into, she drags her mother down with her. And that waste of oxygen that is her stepfather. Much more useful people could be breathing that.
