Up Up Girls (K) have a new costume set and logo, following their first solo live show with the new lineup on 2/28.
http://www.upupgirlskakkokari.com/Edit: I watched the 2/28 live. I didn't like most of the setlist, but they're already a little better than they were at their first event performance. Of course Sekine absolutely still stands out as obviously being much more experienced. Yurika (the blue one) weirdly sounds kind of like Saho Akari sometimes? Really threw my brain once when I wasn't looking at the screen.
UUG(2)'s Yuria has graduated from high school.
