Obana, an investigator, usually works at a cabaret club to gather information. Recently, patch-type aphrodisiacs using illegal ingredients have become prevalent, and in order to eradicate the criminal organization that deals with aphrodisiacs, I will contact a man who has information. I went to a hotel with a man to get information, but since I didn’t say anything important, I made the man drink a capsule-type transmitter under the guise of a drunkenness, and found out the location of the organization.
