Sorry, if I missed this, but do we know how many albums there will be?
Because Album 01 has Miracle Night sung by Haruka Amami, Makoto Kikuchi, Ami Futami, Mami Futami, and Iori Minase. Then, you have Album 02 which has Boku-tachi no Resistance sung by Miki Hoshii, Chihaya Kisaragi, Yayoi Takatsuki, and Hibiki Ganaha. So, what's left is Azusa, Takane, and Ritsuko for the next song.
So, will there be more albums with songs sung by a different set of 765 pro idols? Sounds kind of short to stop at Album 03.
