Risa Aioi

Occupation: Police Detective, Tokyo Metropolitan Police

Five years ago, she got abducted and ended up developing stockholm syndrome. She now has a tendency to fall in love with culprits based solely on the fact that they're criminals. Aioi is unlikely to arrest the preparator due to that fact. However, no preparator would ever run away with her. She also keeps photos of the people that she loved in the past in her own personal space in the precinct.
