That's true. If this isn't the training camp round and she isn't in Tokyo she probably hasn't had to sign some confidentiality agreement. What was her followers on Twitter before the wota found her? Was it really little? If it was like less then 50 she probably didn't think anything of asking the question because it was probably mostly friends and family.
Can't we all tweet Tsunku and send him the link. Someone translate a good sentence into Japanese and we can all spam him with pleads for Cuca's addition to 11th gen. My only worry is that Tsunku wouldnt hold another audition for a year or two and I'm betting it will be after Sayumi and Reina graduate. Still we don't know when that will be and after that I'm going to assume another HUGE gap in auditions platinum era style unless a kyukkie or Jyukkie graduates shortly after.
