Obana, an investigator, usually works at a cabaret club to gather information. Recently, she has been exposed to patch-type aphrodisiacs using illegal ingredients, and in order to eradicate the criminal organization dealing with aphrodisiacs, she will contact a man with information. She goes to a hotel with a man to get information, but she doesn't tell the point, so she pretends to wake up from drunkenness and makes the man drink a capsule-type transmitter to find out the location of her organization.
