Risa Aoyanagi holds the position of Inspector within Division 02 of the Criminal Investigation Department at the Ministry of Welfare's Public Safety Bureau, identified by number 00475-AEFD-98369-1 and operating under the codename Balto 1. Born December 9, 2084, she stands at 172 cm with a slender, fit physique. Her features include brown eyes, dark brown hair cut bluntly with side bangs swept right, and a distinguishing beauty mark beneath her left eye. Her registered address is in Tokyo's Koto Ward, Fukagawa district, with her father, Takeshi Aoyanagi in Kokubunji City, as her emergency contact. Aoyanagi graduated from Tokyo Metropolitan Daichi Junior High School in March 2100 and enrolled at the Private Inada Academy of Higher Education. She majored in Electronic Information Engineering within the Faculty of Information Engineering, graduating in March 2104. That April, she joined the Public Safety Bureau's Career Training Institute, completing training by September. She was immediately assigned as Inspector to Division 02 in October 2104. She obtained a standard automobile driver's license in March 2104 and an Information Security Specialist license in December 2107. Her personality blends professionalism with underlying warmth. Characterized as restrained, capable, and possessing a mature demeanor, she demonstrates a strong sense of justice and dedication to protecting civilians, persisting in her duties despite injury or disadvantage. She maintains firm belief in the Sibyl System's judgments, though this conviction falters when confronted with criminals exhibiting unexpectedly low Crime Coefficients, causing emotional distress. A playful side emerges through her enjoyment of games, and she occasionally socializes with colleagues, such as sharing drinks with Nobuchika Ginoza at his dormitory. Aoyanagi's history includes significant personal tragedy: in February 2113, she was compelled to use a Dominator's Lethal Eliminator mode on Ryogo Kozuki, an Enforcer under her command for approximately ten years who attempted to flee during the Helmet Riots. This event caused profound grief, with sources implying a romantic relationship may have existed between them prior to his demotion. Her investigative work features in *Sinners of the System: Case.2 - First Guardian*, set summer 2112. Teaming with veteran Enforcer Tomomi Masaoka, she investigates an unmanned drone attack on the Ministry of Defense. This case involves military pilot Teppei Sugo, whose squad was killed during an overseas operation. Aoyanagi and Masaoka uncover a military bio-weapon test that caused the squad's deaths, leading to Sugo's mental deterioration and eventual recruitment as an Enforcer. During this investigation, she treats Masaoka with respect, reflecting her collaborative approach. Within Division 02, Aoyanagi maintains professional relationships. She considers Nobuchika Ginoza a friend due to their simultaneous entry into the Bureau, though their interactions remain largely work-focused. Her relationship with Akane Tsunemori is collegial but marked by disagreement over Tsunemori's perceived recklessness in detective work. Aoyanagi experienced Tsunemori's poor cooking skills firsthand when offered instant noodles augmented with poorly prepared vegetables and eggs. Her narrative concludes during *Psycho-Pass* Season 2 events. Responding to a hostage crisis at a mental health facility manipulated by antagonist Kirito Kamui, Aoyanagi attempts to protect civilians. Kamui engineers a scenario where the hostages' Crime Coefficients spike artificially, forcing Division 3 personnel to deem them targets for lethal elimination. In the ensuing chaos, Aoyanagi is fatally shot by a Dominator wielded by Sugo, now an Enforcer under her command. Kamui orchestrated this outcome to test whether Dominators could be used against fellow officers.
