Investigator Kohana usually works at a cabaret club to gather information. Recently, patch-type aphrodisiacs using illegal ingredients have become widespread, and she comes into contact with a man who has information to eradicate the criminal organization that deals in aphrodisiacs. She goes to a hotel with the man to get information, but he won't tell her the important details, so she gives him a capsule-type transmitter, pretending it's a hangover, and finds the organization's location.
