IPZ-580 Extremely ephemeral female investigator Aino Kishi

Aino is a female detective who was once a hostage in a series of female assault cases. At that time, there was a tragic past in which her lover, a colleague detective, died in the line of duty while rescuing Aino...One day, a hostess in Roppongi was murdered, and Aino, who saw the situation at the scene, was the woman at that time. I'm convinced it's the work of a violent demon! A female detective is prepared to sacrifice herself in search of clues to arrest the criminal.
