I may be Kisora biased, but I think she can now go full idol mode at times. She really shined at Tokyo Idol Festival, especially during Jiriri Kiteru.
Tho I still don't understand Ami. I know she's improving and all, but she's still raw af. Why add a new girl that had no singing and dance experience, can't relocate and has to miss several practices?
At this point, I feel like the only way they can improve Tsubaki Factory is to add a few top-notch members (including a really good vocalist) and force the current line-up to step up their game. ^^;
