Another good episode and finally some insight into Misaki's background. It seems she was abused when she was a little younger and has had such an effect on her, that she turned out this way. As Yukimura said "I figured she was just eccentric and helpful", that's how I saw it also. It seems Satou is like the last resort to her life, and if he doesn't need her than no one else will, because in her opinion Satou is lower than her.

I wonder if she'll try and kill herself or something, and Satou saves her, a complete reversal from a few episodes back.

This is also a novel.
