Second season of The iDOLM@STER Cinderella Girls.

Ray is a young wunderkind inventor living in Victorian England. His life is turned upside down when he receives a special package hailing from the United States, sent by his grandfather, Lloyd Steam. The package contains a device called a Steam Ball, a device so powerful that it can drive any machine that requires steam with a nearly limitless amount of energy. Ray is instructed to not let the Steam Ball fall into the wrong hands, which include the mighty O'Hara Foundation, who desperately want to bring the Steam Ball back into their control so they can achieve their less than noble goals. He will need to use every bit of his brilliance in order to dodge the countless goons that are sent to snatch the device from him. It will be a battle between good and evil, a battle for redemption, a battle for the future!

Ten years after the Bubble War, the dichotomy between the rich and the poor in the world becomes more prominent and Japan is no exception. The rich seek to satisfy their desires and derive pleasure for themselves, and Tokyo has materialized into such a city as a result. Saiga, once a war photographer, works for Hibara Ginza in the capitalist state of Tokyo. He infiltrates the Roppongi Club, a secretive base located in the red light district of the city, to collect information about them. However, he was caught in the process and brought forward to a girl called Kagura who was in the midst of a ritual. His contact with Kagura awakens his special ability: the power to make things explode when photographed. In order to unravel the mystery behind the Roppongi Club and Kagura, Saiga begins his solitary battle.

After his father's sudden death, Ceddie moves to England as an heir to his grandfather, the Earl of Dorincourt. The Earl is a stubborn and selfish old man.
