If we actually do start getting adult μ'ses as part of the bluebird storyline is that based or cringe?
Personally i like it since i love mature women and also i've always wanted to see them older after sunshine cucked us out of it. Plus i just think it fits bluebird's setting, when love live and school idols are dead, the most famous group's members coming back to guide these new girls and help revive the culture is a great idea for a sequel. they didnt actually need to be there in sunshine cause it was the opposite scenario where love live was bigger than ever before and aqours were one of many following them
Though if they really return i dont want them to be the entire focus, we have all the new girls too to give character development
