The Stars launched in a hurry and with new CG groups. From previous experience that at most 4 characters can be make in a part. (The only part which used up all 4 quotas in original series is when aikatsu first launched, with Mizuki and Soleil)

The first part finished Hime, Yozora, Yume, Rola first, as Flower Song Class and Moon Beauty Class are the class of Yume, Rola and Koharu, it is normal for 2 senpai perform as demonstration and Yume Rola are the biggest rival.

The second part featured Ako and Mahiru, and also Tsubasa and Yuzu's CG were made for movie.

It is believed that in part 3 Koharu will have the chance but not singing Dream Stage as the singing is free styled, no need to match the characters so Nanase won't be the singer and there will not be live performance. Ep 30, maybe, singing Future Transit/Summer Tears Diary.

Anime is more flexible than that of DCD. They need to prepare the CG models first for DCD. Anime can arrange different performance so as to cover the unmade models.
