The anime version of Kurosugi Shinsaku's manga features Rina and Shiori as its main characters. These women are not someone you want to mess with, especially when they're out late at a karaoke bar. One night, the staff at the karaoke bar tries to take advantage of them, leading to an argument over the bill. However, instead of backing down, Rina and Shiori decide to fight back. As a form of revenge, they rape the karaoke staff and force them to have sex with each other.
