Many people are probably familiar with the concept of "singing cowards. Japan is probably one of the few countries where this kind of genre is not something shameful. On the contrary, many young girls over the age of 16 strive to join a famous idol producer in order to become rich and popular. The five girls in this anime are no exception.
