The Idolmaster: Cinderella Girls aired this winter season and showed signs of fatigue throughout the franchise. The studio creates just another idol group for a new anime adaptation and follows the same patterns as its predecessors. Making the girls struggle their way to fame, but in the end all is well.
This formula seems to work since the sales are steady. With sales of blu-ray volume 1 being 1,325 units in the week of April the 27th till May 3rd, plus thousands of extra sales with CD’s in the same week. The interest in the franchise seems high. In total unit size it may not be the best selling anime, but profitable it remains when you consider the high retail prices. Examples such as the Oreimo Volume 4 blu-ray which at release sells for about 7560 yen or 62 USD each or the fancy blu-ray box one of Fate/Stay Night UBW 2015 goes out for about 34463 yen or a whopping 287 dollars.
That being said, the main drive of the Idolmaster anime is the music, which seems to be pretty steady in sales and a good indication that the series is catchy with its audience or even beyond as the music can be targeted to a broader audience and can be more easily distributed.
The Cinderella anime in itself seems to lose some of its charm. As I said, the formula is pretty much the same. Given, it is difficult to change it into something drastically different, but I want them to build more on the characters, an element that was more present in the first Idolmaster adaptation or even Love Live! where the girls are given a background story. The franchise remains best enjoyed in its native region where idol groups are more common and the topic at hand is more relatable.
