She just moved up to 1A on my oshi list! Man....I can't imagine anyone in the 48G with the stones to do that!!!!
OMG....she's just incredible!!!
Well... It's been kind of done many times before. NMB48 did a couple of Nagiichi lives wearing bikini tops, Amai kokanketsu suit was mostly a bikini, for some time in Blue Rose live they were with the jacket closed and eventually some of them would open it an show a bikini (I remember Ohori and Sayaka doing it), the previous year (or maybe the year before) there was a Summer festival in which a lot of girls did a bikini competition and went on stage wearing it, and SKE48 has done the same more than once in concerts.
