I don't mind the guests, really. They're probably there to keep the 3 girls from getting worn out too fast.
I also like the setlist. They didn't sing those songs that have been beaten to death like Shall We love, Momoiro, All For One, etc. The only regret for me is that there's no 2nd Tanpopo song.

Oh, and that there's no duet within the group. I was expecting that.
Oh, and if you look at the setlist, except for vi-yu-den songs and Otome song, the other songs are totally new to Rika. No Country Rika, no Tanpopo, no MM.
