^^ OMG YES!!! And they put her as center for the dance break too with the dance part that Riho used to have
^ I agree. The group is pretty flexible in that sense because they have the right amount of established talent as a reliable "go to", but when recording comes and suddenly other members have either improved or done miraculous takes, they have enough room to give either older (in terms of seniority) emerging talent like Erina or younger like Miki an actual chance at spotlight along with the established talent, which was showcased well in their latest single. Then, of course, there are members who are still budding who will occasionally get nudged (like Akane and Haachin getting serifus), but there's not too many members like that that it leaves the group to rely on only the same few established members single after single, resulting in predictability as to who will get lines/spotlights in new songs and issues regarding the same few people "hogging" all the lines single after single.

And this is suppose to be one of Kobushi's "back girls." That group just doesn't know the meaning of "weak members," it's simply that some are weaker by comparison but they're all strong lol
