Goth: Wristcut Jiken

Morino is the strangest girl in school—how could she not be, given her obsession with brutal murders? And there are plenty of murders to grow obsessed with, as the town in which she lives is a magnet for serial killers. She and her schoolmate will go to any length to investigate the murders, even putting their own bodies on the line. And they don't want to stop the killers—Morino and her friend simply want to understand them.
