Kentarou, Ryou, and Kazuhiko of the yakuza have failed their boss for the last time. They face a daunting decision: organ harvest and sale or a trip to Thailand for sex reassignment surgery to become pop idols. Following a year of strenuous training, the brute trio transforms themselves into Airi, Chika, and Mari, collectively known as The Goku Dolls. Their aspiration to become the top idol group, however, is challenged by the persistence of their yakuza nature despite extensive feminization conditioning. In an effort to remedy this, their boss hires the renowned manager, Mandarin Kinoshita, who has never had an idol group fail under his leadership. Now, with their futures hanging in the balance, the yakuza members must cooperate with their new manager to discover their inner charm and achieve the success that their domineering boss can genuinely take pride in.
