>>4320187I like Sonia and Chiaki.
I liked Sayaka when she was the cutesy designated love interest, but it became hard to tell what they wanted her personality to be after the murder. Like they went back and forth on her morality too much, and I'm more of the type to prefer her normal side than the psychotic one. To contrast, Sonia has weird disturbing interests but they make it clear she still cares about everyone and doesn't want anyone to die, despite her fascination with learning about serial killers and how they have a different "value system."
