Description

Just before their long awaited major label debut, the idol Ridori-Troy is caught in a car accident. When they wake up, they find themselves in a different world like the Warring States Period, where idols are militant.

In order to return to their original world, they have to meet the ruler of the other world, the "Tenka-bito". In order to do so, the boys have to participate in a contest to determine the number one idol, but this is the beginning of hardship.
