Three girls from Edo who belong to a certain entertainment agency and are an idol unit before their debut, ‘Shitamachi Shojotai’. When they debuted, they were strictly instructed by three people, the president, producer, and assistant producer. Guidance and, of course, sexual harassment lessons. It begins with a series of abuse and punishment electric massage machines, and forced sex. A debut that was greeted with endurance to endure such austerity. However, at the time of the toast, they are forced by drunken men and end up in a big orgy.
