Back Street Girls -GOKUDOLS- - S01

After failing their boss one last time, yakuza members Kentarou, Ryou, and Kazuhiko are given two options: have their organs harvested and sold, or fly to Thailand for sex reassignment surgery and become pop idols. A year of brutal training later, the three thugs have been reborn as Airi, Chika, and Mari. They debut as the amateur idol group The Goku Dolls and set their sights on making it to the top. But even after all the feminizing brainwashing they were forced to sit through, the three idols have kept the yakuza spirit alive in their hearts. To fix that, their boss brings in Mandarin Kinoshita, a legendary manager whose idol groups have never failed. With their lives on the line, the reluctant yakuza have to work with their new manager to unleash their inner cuteness and become the kind of successful idols their tyrannical boss can truly be proud of.
