K.K. gained sudden fame through attention on internet and TV commercials. Her talent agency is a company named ●ss●-, with part of the initials concealed here to imply the real name without directly stating it.

The existence of such material offers a glimpse into the hidden side of the entertainment industry, and the circumstances of its release and distribution represent a true symbol of the underground world.
