Sheryl's manga premiere extra pages:

Q: At first, she only had one song?
K: Before we found May'n, sheryl's connection with the story was just as far as singing one or two songs.

Ranka's booklet:

Kawamori: It's always the more interesting to start off at the point before somebody becomes an idol
K: If we're still doing a slow pace in today's era, nobody would be interested at all. So we decided to showcase a girl who is already popular and let the audience hear her sing, so that we could use her to describe the process of another girl's rise to being an idol at the same time.

There is a lot more to translate, maybe somebody here can help us a bit
