The IDOLM@STER Cinderella Girls: U149

アイドルマスター シンデレラガールズ U149

The U149 in the title refers to the aspiring idols at the center of it all: who stand at under 149 centimeters tall. Together with the help of their similarly squat rookie producer, these idols aim to make it to the top! As the announcement card puts it:
"This story is about growth of little idols and their little producer."
