After an unspecified major failure, Yakuza underlings Kentaro, Ryo and Kazuhiko are forced by their boss, Inugane, to either commit seppuku and sell their organs or go to Thailand to undergo sex reassignment surgery, and train to become idols. They choose the latter and debut as Airi, Mari and Chika, the Gokudols. They suffer abuse from Inugane as he trains them to become idols. Still, their hearts are Yakuza, and their brotherhood is strong.
