Suema was Dr. Kisugi's final victim—or would have been, five years before the series begins. That brush with a serial killer left a mark; she became deeply fascinated by criminal psychology, which honestly made her stick out among her peers. Most people didn't really get why she was so into it.
Her life takes another turn when she meets Nagi Kirima. Through that connection, Suema develops a parallel obsession with the strange supernatural events happening around her city. As the Boogiepop series unfolds, she's constantly digging, trying to piece together what's really going on behind all the incidents that keep happening. It's this dual interest—the criminal underworld and the unexplainable—that drives her forward throughout the story.
