SUPER☆GiRLS without Saori is very surreal, but I'm so excited for Koume! I would have followed her in any group she ended up joining. I think she'll be a great fit and will really, really help the group. Saori was my second favorite member, and now it's easily Koume. Saori included a photo of the audience at Pacifico Yokohama and the turnout looked great (it's a 5,000+ venue). Rika is the new leader and color coding for the new members is silver for Koume, light green for Naapon, and royal blue for Risa.
The first single with the three new members, evidently performed during the encore.
